Macroeconomics

Macroeconomics studies the economy as a whole, operating with aggregated indicators. Unlike microeconomics, which analyzes the behavior of individual economic agents, macroeconomics examines aggregate output, the general price level, aggregate employment, and other indicators that characterize th...

The central concept in macroeconomics is aggregate output — the total volume of goods and services produced in the economy over a certain period. The most common measure of aggregate output is gross domestic product (GDP). GDP represents the market value of all final goods and services produced w...

There are three equivalent methods of calculating GDP. The production method sums the value added by all sectors of the economy. The expenditure method aggregates all expenditures on final products: household consumption, firm investments, government purchases, and net exports. The income method ...

The formula for GDP by expenditure is as follows: Y = C + I + G + NX, where Y is gross domestic product, C is consumer spending by households, I is gross private domestic investment, G is government purchases of goods and services, and NX is net exports (exports minus imports).

National Accounts: The System for Measuring the Economy The System of National Accounts (SNA) is a comprehensive statistical toolkit for the measurement and analysis of macroeconomic processes. It allows for systematic tracking of income and expenditure flows, the formation and use of savings, an...

Main Macroeconomic Income Indicators Gross Domestic Product (GDP) measures the value of products produced within the country, regardless of the nationality of the factors of production. Gross National Product (GNP) takes into account the products produced by national factors of production, regard...

Net National Product (NNP) is obtained by subtracting depreciation from GNP: NNP = GNP – depreciation. NNP reflects the “net” increment in the nation’s wealth, not including spending on restoring worn-out capital.

National Income (NI) represents the aggregate income earned by all factors of production: NI = NNP – indirect taxes + subsidies. National income breaks down into wages, corporate profits, interest, rent, and self-employment income.

Components of GDP: Anatomy of Economic Growth A detailed analysis of the components of GDP allows us to understand the sources and quality of economic growth. Each component has its own dynamics, drivers, and cyclical characteristics. For an investor, the ability to read the structure of GDP open...

Consumption: The Largest Component of the Economy Household consumer spending traditionally accounts for 50% to 70% of GDP in developed economies. Consumption is divided into three categories: durable goods, non-durable goods, and services.

Durable goods include automobiles, furniture, household appliances, and electronics. This is the most volatile component of consumption, highly dependent on the economic cycle and consumer confidence. In periods of economic uncertainty, consumers postpone purchases of expensive goods, making this...

Non-durable goods cover food products, clothing, fuel, and other everyday demand goods. This component is more stable, since basic needs must be met regardless of the economic situation.

From Macroeconomics to Corporate Profits Macroeconomic indicators do not exist in isolation from financial markets. Growth in real GDP, the structure of demand, and the output gap directly and indirectly influence corporate revenues, equity valuation multiples, and sector allocation. Understandin...

GDP and Corporate Profits Aggregated corporate profits are closely linked to nominal GDP. Empirical studies show that over the long term, growth in corporate profits roughly corresponds to growth in nominal GDP. However, in the short term, profits are significantly more volatile than GDP due to c...

Structural changes also affect the profit share. Globalization and technological shifts over recent decades have contributed to an increase in the profit share within developed economies, owing to a decrease in labor’s share. However, this trend may reverse under the influence of political and de...

Valuation Multiples and Economic Growth Equity valuation multiples (such as P/E, EV/EBITDA, and others) are sensitive to expectations of economic growth. Higher expectations for GDP growth usually support higher multiples, as investors are willing to pay a premium for anticipated future profit gr...

GDP per Capita: Measuring Well-being GDP per capita is one of the most commonly used indicators for international comparisons of the level of economic development and well-being. This indicator is calculated by dividing a country’s nominal or real GDP by its population. Despite its apparent simpl...

Nominal GDP per Capita Nominal GDP per capita is calculated at current prices and converted into a single currency (usually US dollars) at the market exchange rate. This indicator is useful for assessing a country's economic weight in the global economy and its purchasing power in international m...

Purchasing Power Parity (PPP) Purchasing Power Parity (PPP) is a theoretical exchange rate at which an identical basket of goods and services costs the same in different countries. PPP eliminates the impact of differences in price levels and allows for a more accurate comparison of the real stand...

Differences Between Nominal GDP and GDP at PPP For developed countries with a high price level (the US, Switzerland, Scandinavian countries), GDP at PPP is usually lower than nominal GDP. For developing countries with lower price levels (China, India, Russia), GDP at PPP is significantly higher t...

Structural characteristics: the anatomy of the economy Understanding the structural characteristics of an economy is critically important for macroeconomic analysis and investment decisions. The structure of the economy determines its sensitivity to various shocks, its growth potential, inflation...

The classic division of the economy distinguishes three sectors: primary (agriculture, extraction), secondary (manufacturing, construction), and tertiary (services). Modern classification often adds a quaternary sector (information technology, finance, R&D). The share of sectors in GDP and employ...

For an investor, the sectoral structure determines the country's sensitivity to various factors. Economies with a high share of extractive industries (Russia, Saudi Arabia, Norway) are highly dependent on commodity prices. Economies dominated by manufacturing (Germany, South Korea, China) are sen...

The degree of openness of an economy is measured by the ratio of external trade turnover (export + import) to GDP. Small open economies (Singapore, Netherlands, Belgium) have an indicator above 100%—trade turnover exceeds GDP due to re-export and deep integration into global supply chains. Large ...

Labor Market: Key Concepts and Indicators The labor market is one of the most important macroeconomic markets, directly influencing the welfare of the population, consumer spending, and inflationary processes. For investors, labor market analysis provides valuable information about the state of t...

Structure of the Labor Force The working-age population includes all individuals of a certain age, usually from 16 to 64 years, who are potentially capable of working. However, not all working-age citizens wish or are able to work. The labor force is the part of the working-age population that ei...

Employed are individuals who have a job, regardless of whether it is full-time or part-time employment. Unemployed are individuals who do not have a job but are actively seeking it and are ready to start working.

Key Labor Market Indicators The unemployment rate is the ratio of the number of unemployed to the size of the labor force:

Classification of unemployment: causes and characteristics Unemployment is heterogeneous in its nature and causes. Understanding the different types of unemployment is critically important for assessing the state of the economy and the prospects of monetary policy. Each type of unemployment has i...

Frictional unemployment Frictional unemployment arises in the process of the normal functioning of the labor market and is associated with searching for jobs and changing places of employment. Even in a perfectly functioning economy, it takes time for workers to find suitable vacancies, and for e...

Structural unemployment Structural unemployment arises due to a mismatch between workers’ skills and qualifications and the requirements of existing vacancies. This mismatch may be geographical (jobs and workers are located in different regions), professional (other specialties are in demand), or...

Cyclical unemployment Cyclical unemployment is associated with fluctuations in economic activity and occurs during periods of recession, when aggregate demand falls below the potential level. When demand for goods and services declines, companies reduce production and lay off workers. Cyclical un...

NAIRU: the connecting link between the labor market and inflation The concept of NAIRU (Non-Accelerating Inflation Rate of Unemployment) is key for understanding the relationship between the labor market and inflation. For investors, NAIRU serves as a benchmark for assessing inflation risks and f...

Theoretical Foundations of NAIRU NAIRU represents the level of unemployment at which inflation remains stable—neither accelerating nor decelerating. If actual unemployment falls below NAIRU, the labor market becomes tight, workers gain stronger bargaining positions regarding wages, and wage growt...

NAIRU is closely related to the concept of the natural rate of unemployment but has a more operational character. Central banks use NAIRU estimates to calibrate monetary policy: if unemployment is significantly below NAIRU, this is a signal for tightening; if above—for easing.

Estimating NAIRU and Its Uncertainty NAIRU is not directly observable and must be estimated using statistical methods. This creates significant uncertainty: NAIRU estimates for the same country and period may differ by 1–2 percentage points depending on the methodology. NAIRU estimates are revise...

The state of the labor market has multiple channels of influence on financial markets and investment decisions. Understanding these channels allows an investor to translate employment and unemployment data into portfolio positioning.

Central banks consider the labor market as a key indicator of economic activity and inflationary pressure. The US Federal Reserve has a dual mandate: maximum employment and price stability. The European Central Bank, while formally focusing on inflation, also takes the condition of the labor mark...

The labor market affects corporate profits through several mechanisms. Wages are the largest line item of operating expenses for most companies. Wage growth squeezes operating margins if companies cannot fully pass on cost increases to prices. Employment and wages define the disposable household ...

The impact of the labor market differs by sector depending on labor intensity and pricing power. Labor-intensive sectors with limited pricing power (retail, restaurants, hotels) are most vulnerable to wage growth. Their margins are squeezed, and the ability to pass on costs to prices is limited b...

Hysteresis in the Labor Market Hysteresis (from the Greek “lagging behind”) describes a phenomenon whereby temporary shocks have a permanent impact on the economic system. In the labor market, hysteresis means that periods of high unemployment can lead to a sustained increase in the natural rate ...

Mechanisms of Hysteresis Loss of human capital is one of the key channels of hysteresis. Prolonged unemployment leads to the loss of professional skills, especially in rapidly changing industries. Technologies develop, work methods change, and the unemployed person loses touch with these changes....

The "insider-outsider" effect describes the division of the labor market into insiders (those with jobs) and outsiders (the unemployed). Insiders possess bargaining power in relations with employers, since replacing them involves costs. In wage negotiations, insiders do not take into account the ...

Stigmatization of the long-term unemployed creates informational asymmetry. Employers consider prolonged unemployment as a signal of low productivity or motivation of the candidate, even if the real cause was a macroeconomic shock. Studies show that résumés with a long break in employment receive...

Measuring Inflation: Indices and Methodology Inflation—a persistent increase in the general price level—is one of the most important macroeconomic phenomena, directly affecting investment returns, monetary policy, and economic welfare. Accurate measurement of inflation represents a complex method...

Consumer Price Index (CPI) The Consumer Price Index (CPI) is the most widely used measure of inflation. It measures the change in the cost of a fixed consumer basket of goods and services, representative of the expenditures of a typical household. The methodology for calculating the CPI includes ...

The inflation rate is calculated as the percentage change in the index over a period: $\pi = \frac{CPI_t - CPI_{t-1}}{CPI_{t-1}} \times 100\%$.

Usually, annual rates (change over 12 months) and monthly rates (change over a month, often annualized) are published.

Types of inflation: mechanisms and sources Inflation can have various causes and mechanisms of development. Diagnosing the type of inflation is critically important for selecting appropriate economic policy measures and assessing investment consequences. Demand-pull inflation, cost-push inflation...

Demand-pull inflation arises when the aggregate demand in the economy exceeds the aggregate supply at current prices. Excessive demand leads to rising prices, as buyers compete for a limited quantity of goods and services. Causes of excessive demand include expansionary monetary policy (low inter...

Demand-pull inflation is usually accompanied by economic growth, low unemployment, and a positive output gap. This is a “good” type of inflation in the sense that the economy is operating at full capacity. However, it requires tightening of monetary policy to prevent overheating.

The classic monetarist position states that “inflation is always and everywhere a monetary phenomenon.” From this point of view, sustained demand-pull inflation is possible only with excessive growth of the money supply.

The Phillips Curve describes the empirical relationship between inflation and unemployment and is one of the central tools of macroeconomic analysis and monetary policy. Understanding this relationship is critically important for forecasting inflation and for the actions of central banks.

In 1958, New Zealand economist William Phillips discovered a stable negative relationship between the rate of nominal wage growth and the level of unemployment in the United Kingdom during the period from 1861 to 1957. Later, this relationship was reformulated in terms of price inflation and unem...

The intuition of the Phillips Curve is simple: when unemployment is low, the labor market is tight, workers have strong bargaining positions, wages rise, costs increase, and companies raise prices. When unemployment is high, workers' bargaining power is weak, wage growth slows, and inflation decr...

Initially, the Phillips Curve was interpreted as a stable trade-off between inflation and unemployment: policymakers could choose a combination of low unemployment with high inflation or high unemployment with low inflation.

Inflation and Investment Returns Inflation has a fundamental impact on investment returns, eroding the purchasing power of nominal incomes. Understanding the difference between nominal and real returns, as well as the impact of inflation on various asset classes, is a key skill for an investor.

Nominal and Real Return Nominal return is the return expressed in monetary units without considering changes in purchasing power. Real return is nominal return adjusted for inflation, reflecting the change in real purchasing power. Approximately, the real return is calculated as the difference be...

Fisher Equation The Fisher equation connects nominal and real interest rates with inflation expectations: $ i = r + \pi^e $ where $i$ is the nominal rate, $r$ is the real rate, and $\pi^e$ is expected inflation. This equation has important practical implications. Nominal rates should compensate...

Impact of Inflation on Asset Classes Fixed-rate bonds are the most vulnerable assets to inflation. Inflation growth reduces the real value of fixed coupons and principal, and also leads to an increase in nominal rates and a decline in bond prices. Long-term bonds are more sensitive due to their g...

Inflation expectations play a central role in modern macroeconomics and monetary policy. If economic agents expect high inflation, they make decisions that turn this inflation into reality—workers demand wage increases, companies raise prices, landlords increase rents. Understanding the mechanism...

Adaptive expectations assume that people extrapolate from past experience. Expected inflation is formed on the basis of actual inflation in previous periods. If inflation was 5%, people expect approximately the same inflation in the future. This model describes the inertia of inflationary process...

Rational expectations, proposed by Robert Lucas, imply that economic agents use all available information and understand the structure of the economy. They do not make systematic errors in their forecasts. If the central bank announces policy easing, rational agents revise their expectations upwa...

In practice, expectation formation represents a hybrid of these approaches. Some agents monitor policy and macroeconomic data closely. Others rely on simple extrapolation rules. The degree of “rationality” depends on the costs of acquiring information and the benefits of more accurate forecasts.

The Aggregate Demand and Aggregate Supply Model (AD-AS) is a central tool of macroeconomic analysis, enabling an understanding of the mechanisms for determining the price level and the volume of output in the economy. For an investor, the AD-AS model provides a framework for interpreting macroeco...

Aggregate demand (AD) represents the total volume of goods and services that all economic agents are willing to purchase at each given price level. The AD curve reflects a negative relationship between the price level and real output: when prices decrease, aggregate demand increases; when prices ...

Aggregate demand consists of four components: household consumption (C), firm investment (I), government purchases (G), and net exports (NX):

Changes in aggregate demand at a constant price level lead to a shift in the AD curve. A rightward shift indicates an increase in aggregate demand, a leftward shift a decrease.

Aggregate supply (AS) describes the overall volume of goods and services that producers are willing to produce and sell at every given price level. There is a fundamental difference between short-run and long-run aggregate supply, and this distinction is key to understanding macroeconomic dynamics.

In the long run, the volume of production is determined by real factors—capital stock, quantity and quality of labor, technologies—and does not depend on the price level. The long-run aggregate supply curve (LRAS) is vertical and located at the level of potential GDP. Potential GDP is the maximum...

A shift in LRAS signifies a change in the productive potential of the economy. Shift factors include capital accumulation (investment), growth of the labor force (demographics, migration), technological progress (innovation, R&D), and improvement of institutions (property rights, rule of law).

In the short run, there is a positive relationship between the price level and the volume of production: as prices rise, producers are willing to increase output. The short-run aggregate supply curve (SRAS) has a positive slope. The positive slope of SRAS is explained by several mechanisms.

Equilibrium in the AD-AS Model The AD-AS model allows one to analyze how the interaction of aggregate demand and aggregate supply determines the price level and the level of production in the economy. Equilibrium and deviations from it have direct consequences for inflation, unemployment, and fin...

Short-Run Equilibrium Short-run equilibrium is achieved at the intersection point of the AD and SRAS curves. At this point, the amount of output that firms are willing to produce equals the amount of output for which there is demand. The price level balances demand and supply. Short-run equilibri...

If short-run equilibrium lies to the left of LRAS, the economy produces less than potential—a recessionary gap. If it lies to the right—the economy is overheated, creating an inflationary gap.

Transition to Long-Run Equilibrium The economy tends to return to long-run equilibrium through the mechanism of wage and price adjustment. In the case of a recessionary gap, high unemployment puts downward pressure on wages, shifting SRAS downward, increasing output and reducing prices. In an inf...

Macroeconomic Regimes and Investment Strategies The economy can be in various "regimes," characterized by different combinations of growth, inflation, and policy. Identifying the current regime and forecasting its change are key tasks of macro investing.

Overheating of the Economy (Overheating) Overheating occurs when aggregate demand persistently exceeds potential output. Characteristic signs include a positive and growing output gap, unemployment below NAIRU, accelerating inflation, rising wages, high capacity utilization, credit boom. In overh...

Investment Implications of Overheating: caution toward long bonds (rate increases), preference for short durations, caution toward growth stocks with high valuations, relative preference for value and cyclical sectors, opportunities in commodities (inflation protection).

Soft Landing Soft landing is a scenario where the economy slows to a sustainable growth rate without recession. The central bank manages to cool an overheated economy without causing a crisis. This is the ideal scenario sought by policymakers, but historically it rarely occurs.

Asymmetric Shocks in the AD-AS Model The aggregate demand and supply (AD-AS) model allows for the analysis of the impact of various economic shocks and the policy response to them. Asymmetric shocks deserve particular attention—situations in which economic disruptions unevenly affect different co...

Classification of Shocks Aggregate demand shocks shift the AD curve. A positive demand shock (increase in consumer confidence, fiscal stimulus, accommodative monetary policy) shifts AD to the right, increasing both output and price levels in the short term. A negative demand shock (crisis of conf...

Aggregate supply shocks shift the AS curve. A negative supply shock (increase in oil prices, natural disasters, trade barriers) shifts AS to the left, simultaneously reducing output and raising prices—creating stagflation. A positive supply shock (technological breakthrough, reduction in regulato...

Policy Dilemmas for Various Shocks Demand shocks create a relatively straightforward policy task. In the event of a negative demand shock, stimulating fiscal and monetary policy can restore output without inflationary consequences. A positive demand shock can be cooled down by tightening policy, ...

Solow Model: the foundation of economic growth theory The Solow model, developed by Robert Solow in 1956, is a cornerstone of the neoclassical theory of economic growth. It explains the long-term dynamics of per capita GDP through capital accumulation, population growth, and technological progres...

Basic assumptions of the model The Solow model is based on a production function that links output (Y) to capital (K) and labor (L) input: $Y = F(K, L)$. The production function demonstrates constant returns to scale: doubling all factors doubles output. At the same time, each factor individually...

The technological level (A) can be incorporated into the model in different ways. In the version with labor-augmenting technological progress, the production function is written as $Y = F(K, AL)$, where $A$ measures labor efficiency.

The key behavioral assumption is that households save a fixed proportion ($s$) of their income. Savings are directed toward investment, which increases the capital stock. Capital is also subject to depreciation at a constant depreciation rate ($\delta$).

Endogenous growth theories: technologies as the engine of the economy Endogenous growth theories, developed since the 1980s, answer a key question left open by the Solow model: where does technological progress come from? In endogenous growth models, technology is the result of purposeful investm...

Critique of exogenous growth The Solow model treats technological progress as “manna from heaven”—an exogenous factor not explained by the model. This is unsatisfactory for several reasons. Technology is the result of human activity, investment in R&D, education, and the infrastructure of knowled...

Romer’s model: R&D and ideas Paul Romer, in his 1990 model, proposed to endogenize technological progress through the R&D sector. Ideas (technologies, knowledge) possess special properties: they are nonrivalrous (use of an idea by one agent does not hinder others) and partially excludable (patent...

AK models: capital in a broad sense The simplest endogenous growth models—AK models—eliminate diminishing returns to capital by broadening its definition. Capital includes not only physical capital, but also human capital, knowledge, organizational capital. The production function $Y = AK$ has co...

Determinants of economic growth: a comprehensive view Economic growth is determined by a multitude of interconnected factors. Understanding these factors allows investors to assess the long-term potential of economies, select country allocation, and identify structural investment themes.

Accumulation of physical capital Investments in physical capital — machinery, equipment, buildings, infrastructure — increase labor productivity and expand the productive capacities of an economy. A high investment rate (the share of investments in GDP) is associated with faster growth, especiall...

Human capital and education Human capital — education, skills, health of the workforce — is a key factor of productivity. More educated workers master new technologies faster, use equipment more efficiently, and are capable of innovation. The quality of education is more important than its quanti...

Technological progress and innovation Technological progress — growth of total factor productivity (TFP) — is the only source of sustainable growth in welfare in the long term. Technologies allow the production of more with the same factor costs. Sources of technological progress include propriet...

Economic growth and investment selection Economic growth is directly connected to investment returns, but this connection is neither simple nor linear. Understanding the nuances of the relationship between growth and returns allows investors to avoid common misconceptions and form more well-groun...

GDP growth and stock returns: the paradox At first glance, it seems obvious that fast-growing economies should provide higher stock market returns. However, empirical data does not support this intuition. The correlation between GDP growth rate and stock returns at the country level is weak or ev...

Quality growth and secular trends For stocks, earnings per share (EPS) growth is more important than GDP growth. Companies able to increase profits faster than the economy owing to competitive advantages, innovation, industry consolidation, are of particular interest—this is the quality growth st...

Emerging markets and convergence Emerging markets have historically demonstrated higher GDP growth rates thanks to the convergence effect. However, translating GDP growth into investment returns is not guaranteed and depends on the quality of corporate governance, protection of minority sharehold...

The middle income trap is a phenomenon of slowing economic growth observed in countries that have reached a medium level of development. Many countries successfully overcome poverty and attain the status of middle-income economies, but then their growth sharply slows down, and the transition to d...

The World Bank classifies countries by gross national income (GNI) per capita. Low-income countries have GNI below $1,085; lower-middle-income countries — $1,086-$4,255; upper-middle-income countries — $4,256-$13,205; high-income countries — above $13,205 (2022 thresholds). Statistics show asymme...

The exhaustion of extensive growth factors explains the slowdown. At early stages of development, growth is ensured by the movement of labor from low-productivity agriculture to industry, capital accumulation, and borrowing of foreign technologies. These sources of growth gradually become deplete...

The Asian Tigers (South Korea, Taiwan, Singapore) overcame the trap through massive investment in education and R&D, government industrial policy, focus on exports, and integration into global value chains. South Korea transformed from a producer of cheap goods to a technological leader in 30 yea...

Business Cycle: Anatomy of Economic Fluctuations The economy does not move along a straight line of growth but oscillates around a long-term trend, passing through phases of expansion and contraction. Understanding the economic cycle—its phases, characteristics, and transitions—is a key skill for...

Classical Phases of the Cycle Traditionally, four phases of the economic cycle are identified: expansion, peak, contraction/recession, and trough.

Expansion is characterized by growth in GDP, declining unemployment, rising company profits, increasing investment, and consumption. In the early stages of expansion, the economy recovers after a recession; in the later stages, it approaches full resource utilization.

The peak is the point of maximum economic activity, after which a downturn begins. At the peak, the output gap is positive, inflation often accelerates, and the central bank tightens policy. Signs of the peak include an inverted yield curve, declining confidence indicators, and slowing profit gro...

Theoretical explanations of business cycles Economists offer various explanations for the causes of economic fluctuations. Understanding these theories helps to interpret current economic events and forecast policy responses. Two main schools—the theory of real business cycles and new Keynesian m...

Real Business Cycle (RBC) Theory The real business cycle theory, developed in the 1980s by Kydland and Prescott, explains cyclical fluctuations by real (not monetary) factors, primarily technological shocks. Economic agents respond rationally to changes in productivity, and these responses create...

New Keynesian Macroeconomics New Keynesians retain the microeconomic grounding of models (rational optimizing agents), but introduce nominal rigidities—stickiness of prices and wages in the short term. These rigidities create the possibility for output fluctuations in response to demand shocks. P...

Monetary Neutrality and Non-Neutrality RBC and classical models assume monetary neutrality: changes in the money supply affect only nominal variables (prices), but not real variables (output, employment). New Keynesians assert short-term monetary non-neutrality: due to price stickiness, monetary ...

Financial cycles: leverage and deleverage In addition to the traditional business cycle, the economy experiences financial cycles—fluctuations in lending, asset prices, and financial conditions. Financial cycles are typically longer and have greater amplitude than business cycles. Understanding t...

Nature of the financial cycle The financial cycle reflects fluctuations in private sector lending, real estate and other asset prices, risk perception, and propensity for leverage. In the expansion phase of the financial cycle, credit grows faster than GDP, asset prices rise, lending standards ar...

Mechanisms of procyclical lending Lending has a pronounced procyclical dynamic. In good times, risk assessments decrease, collateral values rise, banks loosen standards, and borrowers increase debt. In bad times, the process reverses: risk assessments go up, collateral devalues, and credit contra...

Credit spreads and defaults Credit spreads—the difference in yield between corporate and government bonds—reflect perceived credit risk and the phase of the financial cycle. In the expansion phase, spreads narrow, indicating low risk perception and a search for yield. In the contraction phase, sp...

Sectoral dynamics in the economic cycle Different sectors of the economy react differently to the phases of the economic cycle. Understanding sectoral cyclic characteristics allows for sector rotation, increasing portfolio returns depending on the cycle phase.

Cyclical sectors (cyclicals) demonstrate high sensitivity to the economic cycle. Their revenue and profit rise sharply during expansion and fall sharply during recession. These include consumer discretionary goods (automobiles, furniture, entertainment), industrials (equipment manufacturing, cons...

Defensive sectors (defensives) are less sensitive to the cycle. Demand for their products is relatively stable regardless of economic conditions. These include consumer staples (food, beverages, household chemicals), healthcare (pharmaceuticals, medical services), utilities (electricity, gas, wat...

Sectors with mixed characteristics include technology (cyclical component in hardware, defensive in software), energy (depends on oil prices, which have their own dynamics), and real estate (sensitivity to rates and the economy).

Financial cycles: credit, assets, systemic risk Financial cycles describe fluctuations in credit activity, asset prices, and financial leverage in the economy. Unlike traditional business cycles, which are measured by changes in GDP, financial cycles have different amplitude, duration, and charac...

Characteristics of financial cycles Studies by the Bank for International Settlements (BIS) have identified key characteristics of financial cycles. They are significantly longer than business cycles—the average duration is 15-20 years compared to 8-10 years for business cycles. The amplitude of ...

The peaks of financial cycles often precede financial crises. The global financial crisis of 2008 occurred near the peak of the financial cycle in most developed countries. Similarly, the Asian crisis of 1997 followed a credit boom in the region.

Mechanisms of the financial cycle Procyclical lending amplifies fluctuations. During economic upswings, banks are eager to expand lending—collateral valuations rise, defaults are rare, and competition pushes towards loosening standards. Credit growth supports demand and asset prices, creating pos...

Monetary system: fundamentals of monetary analysis Money plays a central role in the functioning of the modern economy, providing exchange, valuation, and preservation of purchasing power. Understanding the nature of money, monetary aggregates, and the banking system is essential for analyzing mo...

Medium of exchange: money eliminates the necessity of a double coincidence of wants characteristic of barter, and significantly reduces transaction costs.

Measure of value: money serves as a unit of price measurement, simplifying comparison of the value of various goods.

In the modern economy, both cash (banknotes and coins) and non-cash money (bank deposits) fulfill the functions of money. The majority of the money supply in developed economies exists in non-cash form.

Instruments of the Central Bank Central banks possess a wide arsenal of tools for conducting monetary policy. Traditional instruments include the management of interest rates and open market operations. Non-traditional instruments, which gained prominence after the global financial crisis, includ...

Key Rate The main instrument of monetary policy for most central banks is the key (or base) interest rate. In the United States, this is the federal funds rate—the overnight interbank lending rate. In the Eurozone, it is the rate on main refinancing operations. In Russia, it is the key rate of th...

Open Market Operations Open market operations (OMO)—the purchase and sale by the central bank of securities (usually government bonds)—are used to manage the liquidity of the banking system and keep the key rate at the target level. When the central bank buys securities, it injects liquidity into...

Quantitative Easing (QE) Quantitative easing refers to large-scale asset purchases by the central bank to further stimulate the economy when the key rate is already close to zero. QE became widely used after the 2008 crisis by the Federal Reserve, ECB, Bank of England, and Bank of Japan. QE works...

How Monetary Policy Influences the Economy The transmission mechanism of monetary policy describes the channels through which decisions of the central bank affect economic activity and inflation. Understanding these channels is necessary for evaluating the effectiveness of policy and its impact o...

The traditional channel operates through the influence of interest rates on investment and consumption. Lowering the key rate makes borrowing cheaper for businesses, making more investment projects profitable. Lower mortgage and consumer loan rates stimulate the purchase of housing, automobiles, ...

The impact on investment is described through the cost of capital. If the expected return from an investment project exceeds the cost of financing, the project is implemented. Lowering rates expands the range of profitable projects.

The time lag between a rate change and its influence on investment and consumption ranges from several quarters to two years. This creates difficulties for fine-tuning the policy.

The yield curve—a graphical representation of the relationship between bond yields and time to maturity—is one of the most important tools for analyzing monetary conditions and economic expectations. The shape of the curve contains information about the market's expectations regarding future rate...

Under normal conditions, the yield curve has a positive slope: long-term rates are higher than short-term rates. This is explained by several factors. The expectations theory asserts that long-term rates reflect expected future short-term rates. The liquidity preference theory adds a term premium...

The short end of the curve (up to 2 years) is closely tied to current and expected central bank policy. The medium and long ends (5–30 years) reflect long-term expectations of growth, inflation, and the term premium.

A normal curve (positive slope) is typical for periods of economic growth. The market expects growth to continue, inflation to be moderate, and the central bank not to radically change policy.

Unconventional Monetary Policy The Global Financial Crisis of 2008 and the subsequent period led to the widespread adoption of unconventional monetary policy tools. When interest rates reached the zero lower bound (Zero Lower Bound, ZLB), central banks were forced to seek alternative ways to stim...

Quantitative Easing (QE) Quantitative easing is the purchase of financial assets (usually government bonds) by the central bank with the aim of increasing the monetary base and lowering long-term interest rates. Unlike traditional management of short-term rates, QE directly affects the long-term ...

The Federal Reserve carried out three rounds of QE: QE1 (2008-2010), QE2 (2010-2011), QE3 (2012-2014), growing its balance sheet to about $4.5 trillion. The European Central Bank launched a large-scale asset purchase program in 2015, expanding it to €2.6 trillion. The Bank of Japan has practiced ...

Negative Interest Rates Negative interest rates once seemed theoretically impossible—why pay to lend money when one could simply hold cash? Nevertheless, a number of central banks (ECB, Bank of Japan, Swiss National Bank, Riksbank, National Bank of Denmark) introduced negative rates on bank depos...

The Government Budget: Revenues, Expenditures, and Balance Fiscal policy—management of government revenues and expenditures—alongside monetary policy, is a key instrument of macroeconomic regulation. Understanding the structure of the budget, sources of revenue, and directions of expenditure is n...

Government revenues consist of tax and non-tax receipts. Tax revenues include income tax (personal income tax), corporate profit tax, value-added tax (VAT) or sales tax, social contributions (for pension and medical insurance), excise taxes (on alcohol, tobacco, fuel), customs duties, property an...

Non-tax revenues include income from government property (dividends of state-owned companies, rental payments), fees and charges for government services, proceeds from privatization, income from natural resources (for resource-rich countries).

The structure of revenues varies across countries. In the USA, income tax and social contributions play the main role. In European countries, the share of VAT and social contributions is higher. In resource-rich countries, revenues from oil and gas are significant.

Government debt—the accumulated volume of government borrowing—is a key indicator of a country's fiscal health. The level and dynamics of debt affect the credit rating, borrowing costs, and long-term economic stability.

The main indicator is the debt-to-GDP ratio. This parameter normalizes the size of debt to the size of the economy, allowing cross-country comparisons and tracking dynamics.

Gross and net debt are distinguished. Gross debt is the total volume of government liabilities. Net debt is gross debt minus government financial assets. For countries with sovereign wealth funds (Norway, Singapore, oil-producing countries), net debt can be significantly lower than gross or even ...

The structure of debt by currencies is important. Debt in the national currency is less risky since the central bank can create money to service it. Debt in foreign currency creates currency risk and default risk.

Fiscal Policy Effectiveness: Multipliers The fiscal multiplier measures the impact of changes in government spending or taxation on GDP. The size of the multiplier determines the effectiveness of fiscal policy as a tool for stimulating or cooling the economy. Estimates of multipliers are the subj...

Multiplier Concept The simplest Keynesian spending multiplier equals $1/(1-MPC)$, where $MPC$ is the marginal propensity to consume. If $MPC = 0.8$, the multiplier equals $5$: an increase in government spending by $1$ dollar raises GDP by $5$ dollars. Mechanism: government spending creates income...

Factors Influencing Multipliers In practice, multipliers are lower than theoretical values due to a number of factors.

Multipliers depend on the state of the economy. In recession, when the economy operates below potential, multipliers are higher: resources are idle, crowd-out effect is minimal, rates are low. Under full employment, multipliers are lower: extra demand creates inflation rather than output growth. ...

The influence of fiscal policy on financial markets Fiscal policy exerts a multi-channel influence on financial markets. Changes in taxes and spending affect economic growth, inflation, interest rates, and corporate earnings. Understanding these interrelations is necessary to assess the market co...

Impact on the bond market Fiscal expansion (growth in spending or reduction of taxes) increases the budget deficit and the need for borrowing. Growth in the supply of government bonds, all other things equal, raises their yields (lowers prices). This supply effect is particularly significant when...

Impact on the equity market Fiscal stimulus during a recession is usually positive for stocks: economic growth supports corporate earnings. However, the effect depends on the structure of the stimulus and the reaction of monetary policy. Lowering corporate taxes directly increases net profit and ...

Sectoral effects Fiscal policy has pronounced sectoral effects. Infrastructure spending is favorable for construction, manufacturers of building materials, heavy machinery. Increases in healthcare spending support medical companies, insurers, pharmaceuticals. Defense spending is important for the...

Fiscal Sustainability: When Debt Becomes a Problem Government debt is a normal instrument of fiscal policy that allows smoothing taxes and expenditures over time, financing investments, and responding to crises. However, excessive accumulation of debt can lead to a debt crisis, default, or forced...

Dynamics of Government Debt The basic debt dynamics equation links the change in the debt-to-GDP ratio with the primary balance and the difference between the interest rate and the growth rate. If the interest rate on the debt exceeds the nominal GDP growth rate ($r > g$), the debt automatically ...

Factors of Debt Sustainability The debt level alone does not determine sustainability. Japan has debt exceeding 250% of GDP without a crisis, while many countries have faced problems at 60-80% of GDP. Key factors include:

Mechanics of Debt Crises Debt crises often develop nonlinearly. Debt may accumulate for years without visible problems until some trigger alters market perception. Typical triggers include: political instability, unexpected recession, rising global interest rates, revelation of hidden liabilities...

Balance of payments: accounting for international transactions The balance of payments is a system for recording all economic transactions between residents of a country and the rest of the world. Analyzing the balance of payments is critically important for understanding a country’s external pos...

Structure of the balance of payments The balance of payments consists of three main accounts: the current account, the capital account, and the financial account. According to the rules of double entry, the sum of all accounts should equal zero (taking into account statistical discrepancies).

The current account reflects trade in goods and services, income from investments (interest, dividends), and current transfers (migrant remittances, aid). The trade balance—the difference between exports and imports of goods—is the largest component. A surplus in the current account means the cou...

The financial account reflects capital flows: direct investment, portfolio investment (stocks and bonds), other investment (loans, deposits), and central bank reserve assets.

Exchange Rates: Nominal and Real The exchange rate—the price of one currency expressed in units of another—is one of the most important macroeconomic variables for open economies. The dynamics of the exchange rate affect export competitiveness, the cost of imports, inflation, and the returns on f...

Nominal and Real Exchange Rates The nominal exchange rate is the relative price of currencies, observed on the foreign exchange market. The quotation can be direct (units of foreign currency per unit of domestic currency) or indirect (units of domestic currency per unit of foreign currency). The ...

where $E$ is the nominal rate, $P^*$ is the price level abroad, and $P$ is the domestic price level. The real rate reflects the relative prices of domestic and foreign goods and determines competitiveness.

The real effective exchange rate (REER) is the weighted average real rate relative to a basket of currencies of trade partners. REER is a comprehensive indicator of international competitiveness.

Currency Parities and Strategies The theory of exchange rates offers several concepts of equilibrium: purchasing power parity and interest rate parity. These concepts, though imperfect empirically, provide guidance for currency assessment and a foundation for investment strategies.

Purchasing Power Parity (PPP) Purchasing power parity states that the exchange rate should equalize the purchasing power of currencies. Absolute PPP: $E = P / P^*$, the rate equals the ratio of price levels. Relative PPP: the change in the rate equals the difference in inflation rates. Empiricall...

Interest Rate Parity Uncovered interest rate parity (UIP) links the difference in interest rates to the expected exchange rate change: $i - i^* = \frac{E^e - E}{E}$, where $i$ is the domestic rate, $i^*$ is the foreign rate, $E^e$ is the expected future rate. According to UIP, a higher rate is of...

Carry Trade Carry trade is a strategy of borrowing in a low-interest currency and investing in a high-interest currency. The profit arises if the high-yield currency does not depreciate by the amount of the rate differential. Empirically, UIP is systematically violated: high-yield currencies depr...

Managing currency risk in investments Currency risk—uncertainty of returns associated with changes in exchange rates—is an inevitable companion of international investments. Understanding the nature of this risk and strategies for managing it is critically important for building global portfolios.

Sources of currency risk For an investor holding foreign assets, the return in the home currency consists of the return of the asset in the local currency and the change in the exchange rate: $r = r^* + \Delta e$ (approximately), where $r$ is the return in the home currency, $r^*$ is the return i...

Currency risk hedging Hedging eliminates or reduces currency risk using derivative instruments. Forward contracts and currency swaps allow one to fix a future exchange rate. The cost of hedging is determined by the difference in interest rates (covered parity). The decision to hedge depends on se...

Currency diversification Holding assets in different currencies provides diversification. If currencies are not fully correlated, some currency movements are averaged out. For a global portfolio, holding assets in many currencies reduces currency risk relative to concentration in a single currency.

Global imbalances: who lends, who borrows Global imbalances—persistent large current account deficits and surpluses in different countries—are one of the central topics in international macroeconomics. The chronic U.S. deficit and the surpluses of China, Germany, and oil exporters create a system...

Measuring imbalances The current account of the balance of payments reflects the difference between exports and imports of goods and services, as well as net investment income and transfers. A current account deficit means that a country consumes more than it produces, financing the difference by...

Causes of imbalances Structural factors explain the persistence of imbalances. The high savings rate in Asia (China, Japan, South Korea) is linked to demographics, underdeveloped social insurance, and cultural factors. The low savings rate in the U.S. reflects the development of consumer credit, ...

Exchange rate manipulation—maintaining an undervalued currency stimulates exports and restrains imports, generating a current account surplus. China was accused of such a policy in the 2000s, accumulating $4 trillion in reserves.

Indicators of the real economy Monitoring macroeconomic indicators allows investors to track the state of the economy in real time and form expectations regarding its future dynamics. Understanding which indicators to look at, how to interpret them, and what impact they have on markets is a key s...

GDP and its components Gross Domestic Product is the most comprehensive measure of economic activity, but it is published with a delay (one month after the end of the quarter) and is subject to revisions. The advance estimate can differ significantly from the final figure. Quarterly GDP growth ra...

Production indicators Industrial Production — a monthly index of output volume in industry. More volatile than GDP, more timely. Important for analysis of the industrial cycle and related sectors. Capacity Utilization shows the degree to which productive capacity is being used. High utilization i...

Consumption and retail sales indicators Retail Sales — a monthly measure of consumer spending in the retail sector. Volatile due to seasonality and irregular purchases (automobiles). Core retail sales (excluding autos and gasoline) are more stable. Consumer Confidence (Consumer Confidence, Consum...

Key Indicators for Monetary Policy Central banks closely monitor labor market and inflation indicators when making decisions regarding monetary policy. For investors, these indicators are critically important for forecasting central bank actions and their impact on financial markets.

Labor Market Indicators Non-farm payrolls (NFP) — the monthly change in the number of employed persons in the US non-agricultural sector — is one of the most influential economic indicators. It is published on the first Friday of the month for the previous month. Strong NFP figures point to a hea...

Unemployment Rate shows the share of unemployed persons in the labor force. A decline in unemployment below NAIRU creates inflationary pressure.

Labor Force Participation Rate reflects the percentage of the working-age population engaged in the labor market. A low participation rate may indicate hidden unemployment.

From Data to Investment Decisions Macroeconomic data only acquires investment meaning within context. The same indicator can trigger opposite market reactions depending on current conditions, expectations, and interpretation. Understanding this context is the key to successfully utilizing macro d...

Role of Expectations Markets trade on expectations. If GDP growth is 3%, but 4% was expected, the market reacts negatively. If growth is 2% with expectations of 1%—positively. The consensus forecast—the average of analysts' expectations—serves as a benchmark for evaluating surprises. Surprise ind...

Context of the Economic Cycle Interpretation of data depends on the phase of the cycle. In the early stages of recovery, strong data is perceived positively: the economy is healing, profits are rising, the central bank maintains an accommodative policy. In late-cycle stages, strong data may be pe...

Central Bank Focus Markets interpret data through the prism of possible central bank reaction. If the Fed is focused on inflation, inflation data will have more impact than growth data. If the priority is employment, labor market numbers take center stage. Central bank communications (forward gui...

Composite Leading Indicators Composite Leading Indicators (CLI) aggregate numerous economic variables that have historically preceded the turning points of the business cycle. These indicators help forecast the direction of the economy over a horizon of 6–12 months. Understanding the methodology ...

Methodology of Construction The OECD publishes CLI for 39 countries and regions. The methodology includes several stages: selection of components, normalization, aggregation. Components are selected based on their leading properties relative to the reference series (usually industrial production ...

The Conference Board publishes the Leading Economic Index (LEI) for the US and other countries. The methodology is similar, but differs in the set of components and weights. For the US, the LEI includes 10 components, among them: average duration of the working week, initial claims for unemployme...

Interpretation of Signals Changes in the direction of CLI signal a possible change in the phase of the cycle. A sustained decline of CLI from a peak precedes a recession, while a sustained rise from a trough indicates recovery. However, not every change in CLI translates into an economic turning ...

Dynamic Stochastic General Equilibrium models, or DSGE models, have become the workhorses of modern macroeconomics, used by central banks and researchers to analyze policy and make forecasts. Understanding the fundamentals of these models helps an investor better interpret the forecasts and scena...

Dynamic: The models describe the behavior of the economy over time, taking into account the intertemporal choices of agents—decisions made today affect opportunities tomorrow.

Stochastic: The models include random shocks—technological, monetary, fiscal—which cause fluctuations in economic variables.

General Equilibrium: The models cover the entire economy, taking into account the interactions between the markets for goods, labor, capital, money. The choices of some agents affect conditions for others.

Vector Autoregressions and Applied Analysis Vector Autoregressions (VAR) are statistical models widely used for the empirical analysis of macroeconomic dynamics, forecasting, and the evaluation of policy effects. Unlike structural DSGE models, VAR models are atheoretical and allow the data to "sp...

Structure of a VAR Model A VAR describes a system of variables in which each variable depends on its past values and the past values of all other variables in the system. The simplest VAR(1) for two variables:

$y_{1t} = a_{11}y_{1,t-1} + a_{12}y_{2,t-1} + \varepsilon_{1t},$ $y_{2t} = a_{21}y_{1,t-1} + a_{22}y_{2,t-1} + \varepsilon_{2t}.$

VAR models do not require a priori theoretical restrictions on the structure of the economy. They estimate dynamic relationships between variables from the data.

Vector autoregression models (VAR) have become one of the main tools of empirical macroeconomics following the work of Christopher Sims in the 1980s. VAR allows for the analysis of interactions between multiple macroeconomic variables, traces the propagation of shocks throughout the economy, and ...

A VAR model represents each variable as a function of its own past values and the past values of all other variables in the system. If we model GDP, inflation, and the interest rate, each of these variables depends on lags of all three variables. The key advantage of VAR is that it requires minim...

The number of lags is chosen based on information criteria (AIC, BIC) or economic reasoning. Too few lags carry the risk of missing important dynamics. Too many lead to a loss of degrees of freedom and overfitting.

Impulse Response Functions (IRF) show how variables respond to a unit shock in one of the variables. For example, how do GDP and inflation react to an unexpected increase in the interest rate? The IRF traces the effect over time, indicating the magnitude, sign, and decay of the response.

Global Macro: investing based on macroeconomic analysis Global macro is an investment style based on the analysis of macroeconomic trends, policy, and global imbalances to form positions in various asset classes and regions. It is a top-down approach, in which the macroeconomic outlook determines...

Philosophy of global macro Global macro investors believe that macroeconomic factors—growth, inflation, policy—are the key drivers of asset class returns. Understanding and forecasting these factors makes it possible to form profitable positions.

Flexibility is a distinctive feature of global macro. Investors can be long or short in any asset class (stocks, bonds, currencies, commodities), in any region, using a wide range of instruments (cash, futures, options, swaps).

Key macro factors Growth and cycles: the phase of the economic cycle determines the relative attractiveness of asset classes. Expansion is favorable for equities; recession—for bonds. Inflation: the inflation regime influences the real return on bonds, the relative attractiveness of nominal vs. r...

Macroeconomic Factors and Asset Classes Different asset classes respond differently to macroeconomic conditions. Understanding these connections allows the translation of a macro perspective into asset allocation.

Government Bonds Government bonds of developed countries are a key instrument for expressing views on interest rates and the economic cycle. Positive conditions: recession, declining inflation, policy easing — growth in bond prices. Negative conditions: economic growth, inflation, tightening — fa...

Corporate Bonds Credit spreads are sensitive to the economic cycle. Widening: recession, increase in defaults, flight from risk. Tightening: economic growth, low defaults, hunt for yield. Relative value: high yield vs. investment grade, emerging vs. developed markets. Macro conditions determine r...

Equities Stocks as a whole respond positively to economic growth and corporate earnings. Negatively — to recessions and policy tightening. However, the relationship becomes more complex: too strong growth → tightening → negative for equities. Sector rotation: cyclical sectors lead in expansion, d...

Global Macro: strategies based on macroeconomic views Global macro is one of the oldest and most respected hedge fund strategies. Managers take directional positions in currencies, interest rates, commodities, and equities based on macroeconomic forecasts. Legendary managers—George Soros, Stanley...

Philosophy of Global Macro Global macro is based on the belief that macroeconomic trends, imbalances, and political changes create predictable asset price movements. Unlike strategies based on fundamental company analysis or technical chart analysis, macro focuses on the “big picture.” Key source...

Typical Trading Themes Divergence of monetary policy is a classic theme. If the Fed tightens policy and the ECB eases, this creates potential for dollar strengthening against the euro and widening of interest rate spreads. Position: long dollar/short euro, receive fixed rate in dollars/pay in euros.

Correction of imbalances—countries with chronic current account deficits, overvalued currency, rising external debt are vulnerable to crisis. Position: short the currency, short sovereign bonds, short banks of that country.

Macro regimes and their impact on assets The economy can be in various regimes characterized by different combinations of growth and inflation. Each regime creates specific conditions for different asset classes. Identifying the current regime and forecasting its change is a key task for the macr...

Classification of macro regimes Growth + low inflation (Goldilocks): an ideal regime for financial assets. Equities grow on profits. Bonds are stable with moderate rates. Central bank is neutral. Credit spreads are narrow. Volatility is low.

Growth + high inflation (Overheating): a risky regime. Equities can rise but face the threat of tightening. Bonds are under pressure due to rates. Commodities and real assets benefit. Volatility increases.

Recession + high inflation (Stagflation): the most challenging regime. Equities fall (recession of profits). Bonds are under pressure (inflation). Commodities may serve as a hedge. High quality defensive assets are valued.

Extreme Scenarios and Portfolio Protection Tail risk—the risk of extreme events with low probability but high impact—requires special attention in portfolio management. Stress testing allows assessment of portfolio behavior under adverse scenarios and preparation of protection strategies.

Nature of Tail Risk Financial markets exhibit “fat tails”—extreme movements occur more frequently than predicted by the normal distribution. “Six sigma” events happen every few years rather than once in a million years. Tail events are often associated with macroeconomic crises: financial crises,...

Integration of macro analysis into the investment process The concluding article of the macroeconomics course unites key concepts into a practical approach to using macro analysis in investing. Macroeconomics is not an abstract theory, but a tool for making more informed investment decisions.

Hierarchy of decisions Strategic asset allocation (SAA): long-term distribution among asset classes based on expected long-term returns, risk, and correlations. Macro factors (long-term growth potential, demographics, institutions) inform country allocation. Tactical allocation (TAA): medium-term...

Constructing a macro outlook Data collection: regular monitoring of key indicators — GDP, employment, inflation, PMI, market data. Use of the publication calendar. Synthesis: integration of data into a coherent picture. Where is the economy in the cycle? What is the dynamic? What imbalances have ...

Resources for macro analysts Official sources: publications of statistical agencies, central banks, international organizations (IMF, OECD, World Bank). Market indicators: yield curves, credit spreads, breakeven rates, implied volatility — reflect market expectations. Research: macroeconomic repo...

Stress testing is an analysis of how a portfolio behaves under extreme but plausible scenarios. In contrast to standard risk management, which focuses on “normal” conditions, stress tests explore tail risks—rare events with catastrophic consequences. After the financial crisis of 2008, stress tes...

Historical scenarios recreate the market conditions of past crises. How would the current portfolio have behaved in 2008? In 2020? During the Asian crisis of 1997? The advantage is realistic correlations and asset behavior. The disadvantage is that past crises may not repeat.

Hypothetical scenarios are constructed based on current risks and vulnerabilities. What will happen if a major economy defaults? In case of a sharp increase in inflation? In the event of a geopolitical conflict? Scenarios are developed by experts and may include events with no historical precedent.

Reverse stress tests start from an undesirable outcome (loss of X% of capital, insolvency) and determine which scenarios could lead to it. This helps to identify hidden vulnerabilities and risk concentrations.

Modern Monetary Theory: a revolution in macroeconomic thinking? Modern Monetary Theory (MMT) is an unorthodox macroeconomic theory that rethinks the role of government finances in countries with a sovereign currency. MMT challenges conventional wisdom about government debt, deficits, and monetary...

Sovereign currency issuer: a country that issues its own freely-floating currency (the USA, Japan, UK) technically cannot “go bankrupt” on debts denominated in that currency. The central bank can always create money to service the debt. This is fundamentally different from households or businesse...

Taxes do not finance spending: in the MMT framework, the government spends first (creates money), then collects taxes (destroys money). Taxes are not needed for financing, but to: create demand for the currency (taxes must be paid in the national currency), control inflation (removal of excess pu...

Real constraints: the limitation to government spending is not financial, but the real capacity of the economy. If spending exceeds productive potential—inflation arises. Inflation, not default, is the real constraint for a sovereign issuer.

Central Bank Digital Currencies (CBDC): The Digital Transformation of the Monetary System

CBDC: Digital transformation of the monetary system. Central Bank Digital Currencies (CBDC) are digital currencies issued by central banks. Unlike cryptocurrencies (decentralized, private), CBDCs represent government money in digital form. More than 130 countries (98% of global GDP) are studying ...

Retail CBDC: digital currency for the general public. A direct claim on the central bank, like cash, but in digital form. Examples: e-CNY (China), e-Naira (Nigeria), Sand Dollar (Bahamas).

Wholesale CBDC: for interbank settlements and financial institutions. Settlement between banks, securities transactions. Less revolutionary, but operationally significant.

Climate Economics: Macroeconomics of the Green Transition Climate change is not only an environmental issue; it is also a first-order macroeconomic problem. Climate change affects GDP growth, inflation, financial stability, and fiscal sustainability. Transition to a low-carbon economy requires a ...

Economics of Climate Change Physical risks: Direct economic losses from climate events—hurricanes, floods, droughts, wildfires. Destruction of infrastructure, agricultural losses, health impacts. Estimates: 10-23% of global GDP by 2100 under business-as-usual (Stern Review, Network for Greening t...

Carbon Pricing Carbon pricing is a central policy instrument for internalizing climate externalities. Cap-and-trade: Government sets a cap on emissions, companies trade permits. EU ETS is the largest system. Price €80-100/ton CO2 (2024). Carbon tax: Direct tax on emissions. Simpler administrative...

Macroeconomics of the Transition Investment requirements: Achieving net zero requires $4-6 trillion annual investment in clean energy, infrastructure, efficiency. Massive reallocation of capital from fossil fuels to renewables. Structural change: Declining industries (coal, oil & gas) vs. growing...
