12.8 Economic development theories

Economic development theories emerged post-World War II to address global disparities. These theories evolved from linear models to complex approaches considering institutional, social, and environmental factors.

Contemporary development challenges include inequality, technological change, and climate impacts. Modern theories emphasize sustainable growth, human capabilities, and institutional quality to promote inclusive development in a globalized world.

Origins of development economics

• Development economics emerged as a distinct field in the mid-20th century focused on understanding and promoting economic growth in less developed countries
• Shaped by the global context of decolonization, Cold War tensions, and the need for post-war reconstruction in many parts of the world
• Sought to address the persistent economic disparities between industrialized nations and the developing world
