Economists have long debated a simple blueprint for poor countries to become rich, but many rapidly developing economies have stalled in what is known as the 'middle-income trap.' According to the World Bank, as of 2024, 108 countries are classified as middle-income, with per capita GDP between $1,136 and $13,845. These nations often struggle to transition from low-cost labor to higher-value industries.
Research by the World Bank and economists like Barry Eichengreen shows that countries such as Brazil, South Africa, and Malaysia have experienced growth slowdowns after reaching middle-income status. The trap occurs when a country loses its competitive edge in low-wage manufacturing but lacks the innovation and infrastructure to compete in advanced sectors.
A 2024 study by the McKinsey Global Institute highlighted that only 13 economies have successfully transitioned from middle-income to high-income since 1960, including South Korea and Singapore. Success factors include investment in education, technology adoption, and institutional reforms.
The World Bank's 2024 World Development Report emphasized that middle-income countries need to shift from 'investment-led' to 'innovation-led' growth to escape the trap. Without such changes, many risk prolonged stagnation.
