Our simple model features agents heterogeneous in skill and risk aversion, incomplete financial markets, and redistributive taxation. In equilibrium, agents become entrepreneurs if their skill is sufficiently high or risk aversion sufficiently low. Under heavier taxation, entrepreneurs are more...

To help first- or second-year graduate students in economics apply their theoretical training, this paper shows how to solve a simple and intuitive computable general equilibrium (CGE) model using a calculator. Because this simplified Harberger model uses Cobb Douglas functional forms for...

Uneven development within countries suggests that domestic trade frictions are important. Trade flows within a country, however, are rarely observed. We employ a new dataset on trade between fifteen Chinese treaty ports to examine the importance of domestic frictions around the year 1900. The...

How likely is trade liberalization to produce efficiency gains in the presence of imperfect competition, scale economies, and higher-than-average wages in the modern sectors -- all common features of developing economies? These features create a potential conflict to the extent that traditional...

This paper reviews recent methodological developments in the empirical analysis of imperfectly competitive markets highlighting outstanding problems. Some of these problems are econometric; e.g. the need for a deeper understanding of the small sample properties of our estimators. Most of the...

This paper develops the idea that when markets are imperfectly competitive, final producers may gain from a joint venture that produces part of their input requirements even though marginal cost exceeds the input's market price. Production by the joint venture lowers the market price of the...

This paper examines the effect of tariffs and exchange rates on U.S. prices of Japanese cars, trucks and motorcycles. In particular, we test whether the long run pass-through of tariffs and exchange rates are identical: the symmetry hypothesis. We find that this hypothesis is easily accepted in...

The global pattern of foreign direct investment (FDI) is quite similar to the world trade pattern. In particular, intraindustry FDI between rich nations is almost as pervasive as intraindustry trade among rich nations. In the standard' MNC model (of Markusen, Venables, Brainard, and others), FDI...
