East Asia experienced extensive economic growth in the second half of the 20th century while Latin America saw stagnated growth and decline. This was largely due to differences in total factor productivity. Latin America adopted import substitution industrialization which led to inefficient state-owned enterprises, high inflation, and vulnerability to external shocks. In contrast, East Asian countries limited government intervention and inflation while promoting exports, education, savings, and sustainable growth through balanced budgets and market policies. As a result, East Asia saw investment exceed 20% of GDP annually and rapid growth, while Latin America suffered from low productivity following economic shocks.
