How does technological progress in financial intermediation affect the economy? To address this question a costly-state verification framework is embedded into a standard growth model. In particular, financial intermediaries can invest resources to monitor the returns earned by firms. The...

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...

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...

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...

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...

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...

This paper studies the interaction between technology, a publicly available input that flows in from abroad, and human capital, a private input that is accumulated domestically, as the twin engines of growth in a developing economy. The model displays two types of long run behavior, depending on...

The empirical relationship between capital controls and the financial development of credit and equity markets is examined. We extend the literature on this subject along a number of dimensions. Specifically, we (1) investigate a substantially broader set of proxy measures of financial...
