Kululähenemine

Kululähenemine, also known as convergence, is a phenomenon in economics where the economic growth rates of different countries or regions become more similar over time. This process is often driven by various factors, including technological advancements, globalization, and the spread of economic institutions and policies. Convergence is a key concept in development economics, as it suggests that economic disparities between countries can be reduced over time.

Theories of convergence propose different mechanisms that explain why countries might experience economic growth and why this growth might be similar across countries. One prominent theory is the Solow growth model, which suggests that convergence occurs due to the accumulation of capital and technology. Another theory, the endogenous growth theory, emphasizes the role of institutions, human capital, and innovation in driving convergence.

Empirical evidence supports the existence of convergence, although the pace and extent can vary. For instance, in the long run, countries tend to converge in terms of per capita income, but the process can be slow and uneven. Factors such as initial conditions, political stability, and the effectiveness of economic policies can influence the convergence process.

Convergence has significant implications for international development and policy-making. It suggests that economic growth is not solely determined by initial conditions but can be influenced by long-term factors. Policymakers often focus on promoting convergence by investing in education, infrastructure, and institutions to accelerate economic growth and reduce poverty. However, achieving convergence requires sustained effort and cooperation among countries to address global challenges such as climate change and inequality.
