摘要：We use a North-South model with property right differences and resource dynamics to study the effects of trade on resource use and welfare. Autarky is likely to Pareto-dominate free trade in the long run when the environment is quite fragile, and the result is reversed when the environment is quite resilient. Trade may cause an environmentally poor country to drag down its richer trading partner, when they degrade their stocks which would be preserved under autarky. It may enable the environme...

摘要：We study a duopoly game in which firms commit to a batch technology before competing in sales quantities. Adopting a batch technology requires the quantity produced to equal an integer number of batches and allows sales to be less than production. When larger batch sizes lower unit production costs (as in the U.S. airline industry with its economics of density), subgame perfect equilibrium sales quantities are unique and more competitive than the Cournot equilibrium quantities of a one-shot ga...

摘要：This article extends Hopenhayn and Rogerson's analysis of firing taxes by introducing a flexible form of capital and considering transitionary dynamics. The article finds that capital is not important for understanding the long run and welfare effects of firing taxes. However, capital is crucial for determining the short run consequences of eliminating this type of policy.

摘要：We propose exact tests and confidence sets for various structural models typically estimated by IV methods, such as models with unobserved regressors, which remain valid despite the presence of identification problems or weak instruments. Two approaches are considered: (1) an instrument substitution method, which generalizes the Anderson-Rubin procedure. and (2) a sample-split method, that allows the use of generated regressors. Projection techniques are also proposed for inference on general ...
