It studies how economic growth, poverty reduction, and social welfare can be achieved through various policies and strategies. This field examines factors such as education, health, and infrastructure, which are essential for fostering sustainable development. Researchers in development economics analyze the effectiveness of international aid, trade policies, and investment in promoting economic progress. They also explore the role of institutions, governance, and social factors in shaping economic outcomes.
