This paper incorporates commodity stockholding into a short run, stochastic global general equilibrium model. A mix of econometric and calibration techniques are used to reconcile model outcomes with historical stockholding and price behavior. The resulting framework is useful for analyzing...

Simple plots of data show that malaria has a negative correlation with national income per capita, whether looking across countries at a point in time, or looking at a single country over time. Some countries have been able to move from an equilibrium characterized by low income and high...

This study tests the null hypothesis that it is sufficient to interview only the household head to obtain accurate information on household income. Results show that using a husband’s estimate of his wife’s income does not produce statistically reliable results for poverty analysis....

This study uses a unique firm-level dataset to examine how falling trade costs from 1993-2001 affected entry, exit, productivity, and exporting in the Korean manufacturing sector. We verify many of the predictions of recent heterogeneous-firm models of international trade. For example, falling...

An analytical model is developed to explain the increasing tendency of pork packers to produce their own hogs. Upstream integration is motivated by recent events including increasing hog buyer consolidation and a need for traceability, but is held in check since it lowers upstream managerial...

The FTC's "shared monopoly" case was the focus of U.S. antitrust activity during the late 1970s, but prosecution of the cereal industry was terminated in 1981. We estimate the degree of market power in the industry, and find an increase in multilateral power after 1981.

We utilize a global trade model to generate distributions of commodity and factor prices based on observed uncertainty in rice production. This is done for three trade policy regimes. We then assess their impact on domestic price variability and the likelihood of marginal households falling into...
