This paper studies the causal mechanisms behind persistent poverty. Using original data on Boran pastoralists of southern Ethiopia, we find that heterogeneous and nonlinear wealth dynamics arise purely in adverse states of nature. In favorable states, expected herd grow is quasi-linear and...

Our main contribution is then...

Using a broad cross-country sample, we distinguish among competing theoretical predictions...

Inward and outward direct investment (FDI) stocks and flows tend to go together, across countries and over time. The countries that invest extensively abroad are usually also large recipients of FDI.

We provide an analysis of real economic growth prospects in emerging markets after financial liberalizations. In contrast with previous research, we identify the financial liberalization dates and examine the influence of liberalizations while controlling for a number of other macroeconomic and...

This paper provides an empirical investigation of the medium-term determinants of current accounts for a large sample of industrial and developing countries. The analysis is based on a structural approach that highlights the roles of the fundamental macroeconomic determinants of saving and...

Since the late 1980s the global intellectual property rights (IPR) system has been strengthening dramatically as much of the developing world introduces patent protection for new drug products. This may lead to more research on drugs to address developing country needs. As there are identifiable...
