We suggest that the geographical patterns of income differences across the world have deep underpinnings. We emphasize that economic development is a complex process driven by economic, political, social, and biophysical forces. Some economists have argued that the patterns reflect mainly the...

We present evidence on the differences in the intensity with which ten major technologies are used in 185 countries across the world. We do so by calculating how many years ago these technologies were used in the U.S. at the same intensity as they are used in the countries in our sample. We...

What obstacles prevent the most productive technologies from spreading to less developed economies from the world's technological frontier? In this paper, we seek to shed light on this question by quantifying the geographic and human barriers to the transmission of technologies. We argue that...

This paper reports on the first randomized evaluation of the impact of introducing the standard microcredit group-based lending product in a new market. In 2005, half of 104 slums in Hyderabad, India were randomly selected for opening of a branch of a particular microfinance institution...

Women's empowerment and economic development are closely related: in one direction, development alone can play a major role in driving down inequality between men and women; in the other direction, empowering women may benefit development. Does this imply that pushing just one of these two...

We explore the impact of British colonial institutions on the economic development of India. In some regions, the British colonial government assigned property rights in land and taxes to landlords whereas in others it assigned them directly to cultivators or non-landlords. Although Banerjee and...

Developing countries made considerable gains during the first decade of the 21st century. Their economies grew at unprecedented rates, resulting in large reductions in extreme poverty and a significant expansion of the middle class. But more recently that progress has slowed with an economic...

Is the high degree of gender inequality in developing countries--in education, personal autonomy, and more--explained by underdevelopment itself? Or do the societies that are poor today hold certain cultural views that lead to gender inequality? This article discusses several mechanisms through...

This research provides a single explanation for: (i) the persistence of malnutrition and (ii) the increased prevalence of metabolic disease (diabetes, hypertension, cardiovascular disease) among normal weight individuals with economic development. Our model is based on a set point for BMI or...

Analyzing a variety of cross-national and sub-national data, we argue that high adult mortality reduces economic growth by shortening time horizons. Higher adult mortality is associated with increased levels of risky behavior, higher fertility, and lower investment in physical and human capital....
