Some critics of privatization argue that poor labor force restructuring is a key concern and that governments should establish better retrenchment programs. Using new data from a sample of 400 companies in the world, Chong and Lopez-de-Silanes test competing theories about the wisdom of...

Using panel data for Peru for 1994-2000, the authors find that when households receive two, or more services jointly, the welfare increases as measured by changes in consumption are larger than when services are provided separately. The increases appear to be more than proportional, as F-tests...

The authors examine the empirical links between current account deficits and a broad set of economic variables proposed in the literature. To accomplish this, they complement and extend previous research by using a large, consistent set of macroeconomic data on public and private domestic...

In much of the developing world, many farmers grow crops for local or personal consumption despite export options that appear to be more profitable.
