I discuss the role of economic theory in empirical work in development economics with special emphasis on general equilibrium and political economy considerations. I argue that economic theory plays (should play) a central role in formulating models, estimates of which can be used for...

Environmental quality in many developing countries is poor and generates substantial health and productivity costs. However, existing measures of willingness to pay for environmental quality improvements indicate low valuations by affected households. This paper argues that this seeming paradox...

In a calibrated version of the model, transition paths after a policy change can display rapid growth, as in modern growth 'miracles.' In these economies policies that promote technology inflows are much more effective than subsidies to human capital accumulation in accelerating growth. A policy...

Per capita income in the richest countries of the world exceeds that in the poorest countries by more than a factor of 50. What explains these enormous differences? This paper returns to several old ideas in development economics and proposes that linkages, complementarity, and superstar effects...

Most recent cross-country analyses of economic growth have neglected the importance of physical geography. This paper reviews the distinctive development challenges faced by economies situated in tropical climates. Using geographic information system (GIS) mapping, the paper presents evidence...

Poor countries must specialize in standardized. labor-intensive commodities. Middle income countries may have a richer menu of options available to them if their labor force is reasonably well-educated and skilled. This paper is motivated by the possibility that there may exist multiple...

Among developing countries, there was no gross relationship between real income per capita in 1960 and subsequent growth in per capita income. However, once other significant influences, such as education, changes in labor force participation rates, inflows of foreign investment, price...

Substantial research in development economics has highlighted the presence of weak institutions, market failures and distortions in developing countries. Yet, much of the knowledge generated in international trade comes from workhorse models that abstract from these frictions. This review...

Research at the intersection of development and spatial economics is increasingly important to address pressing issues in rapidly-urbanizing cities in low- and middle- income countries. This handbook chapter presents the canonical spatial model and then explores it through the lens of...
