We use Bayesian meta-analysis methods to estimate the impact of unconditional cash transfers (UCTs) on twelve primary outcomes from 114 studies of 72 UCT programs in middle and low income countries. Cash transfers generate strong and positive average treatment effects on ten of thirteen...

This paper studies the pattern of allocation of foreign aid from various donors to receiving countries. We find considerable evidence that the direction of foreign aid is dictated by political and strategic considerations, much more than by the economic needs and policy performance of the...

In this paper I discuss the effectiveness of foreign aid from a historical perspective. I show that foreign aid is a relatively new concept in economics, and I emphasize the role of exchange rate policies in the foreign aid controversies of the 1970s through 1990s. I show that in the early 1980s...

The conventional wisdom that Africa is not reducing poverty is wrong. Using the methodology of Pinkovskiy and Sala-i-Martin (2009), we estimate income distributions, poverty rates, and inequality and welfare indices for African countries for the period 1970-2006. We show that: (1) African...

We exploit differences in the mortality rates faced by European colonialists to estimate the effect of institutions on economic performance. Our argument is that Europeans adopted very different colonization policies in different colonies, with different associated institutions. The choice of...

Several studies link modern economic performance to institutions transplanted by European colonizers and here we extend this line of research to Asia. Japan imposed its system of well-defined property rights in land on some of its Asian colonies, including Korea, Taiwan and Palau. In 1939 Japan...

We estimate the respective contributions of institutions, geography, and trade in determining income levels around the world, using recently developed instruments for institutions and trade. Our results indicate that the quality of institutions trumps' everything else. Once institutions are...

Whereas traditional explanations of differences in long-run paths of development across the Americas generally point to the significance of differences in national heritage or religion, we highlight the relevance of stark contrasts in the degree of inequality in wealth, human capital, and...

Does economic development depend on geographic endowments like temperate instead of tropical location, the ecological conditions shaping diseases, or an environment good for grains or certain cash crops? Or do these endowments of tropics, germs, and crops affect economic development only through...
