Factors of Economic Growth

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, especially in the early stages of development. The quality of investment matters no less than the quantity. Investments in modern equipment embodying the latest technologies yield greater returns than investments in obsolete technologies. The effectiveness of investments depends on the quality of corporate governance, the financial system, and institutions. Infrastructure — transport, energy, telecommunications — creates positive externalities for the entire economy. Developed infrastructure reduces transaction costs, expands markets, and increases the productivity of the private sector.

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 quantity. Countries with high results in international tests (PISA, TIMSS) demonstrate higher growth than countries with formally high levels of education but low quality. Test scores in mathematics and natural sciences are especially significant for economic growth. The health of the population affects growth through labor productivity and the duration of active life. Investments in healthcare, especially in basic healthcare and prevention, have high social returns.

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 proprietary R&D (creation of new technologies), borrowing and adapting technologies from abroad, learning by doing, and the dissemination of knowledge through trade and foreign direct investment. For developing countries, borrowing technologies is often more effective than proprietary R&D. Openness to trade and foreign investment promotes the diffusion of technologies. However, for countries on the technological frontier, proprietary R&D is critically important.

Institutions and governance
The quality of institutions — protection of property rights, rule of law, effectiveness of the state, fight against corruption — is a fundamental factor of growth. Institutions determine the incentives for investment, innovation, and entrepreneurship. Weak institutions create uncertainty regarding property rights, increase transaction costs, and contribute to the redistribution of resources from productive activity to rent-seeking. This reduces investment and innovation. Empirical studies show that differences in institutions explain a significant part of cross-country differences in income levels. Countries with strong colonial-origin institutions (where colonizers established institutions for their own residence) are richer than countries with extractive institutions.

Demography
Demographic factors influence growth through the size of the labor force, the demographic dependency ratio, and the accumulation of human capital. The "demographic dividend" — growth in the share of the working population as fertility declines — creates a favorable window for economic growth. Population aging, on the other hand, poses challenges: shrinking labor force, increasing dependency ratio, and pressure on pension and healthcare systems. This is a structural factor affecting the long-term prospects of developed economies.

Application for investors
Assessing growth factors helps in country allocation. Countries with a favorable combination of factors — high investment, quality education, innovation potential, strong institutions, and favorable demography — have better long-term prospects. Structural investment themes are tied to growth factors: infrastructure in developing countries, educational technologies, automation amid population aging, companies benefiting from technological progress.
