In this paper, we build a dynamic model with endogenous firm-level productivity that involves ex ante identical firms behaving differently in equilibrium. Heterogeneity arises in equilibrium as firms choose different dates to adopt a new technology. We investigate the effects of international...

U.S. Presidential Executive Order 13141 commits the United States to a "careful assessment and consideration of the environmental impacts of trade agreements." The most direct mechanism through which trade liberalization would affect environmental quality in the U.S. is through changes in the...

Theoretical ambiguity exists regarding the potential benefits of adopting a uniform tariff schedule. In this paper, we investigate the empirical evidence on this question. From cross-country growth regressions over the period 1988-97 we find a nonlinear relationship between a country's standard...

In numerous studies, economists have found little empirical evidence that environmental regulations affect trade flows. In this paper, we propose and test several common explanations for why the effect of environmental regulations on trade may be difficult to detect. We demonstrate that while...

Barriers to trade are commonly viewed as a result of political systems in which politically influential groups benefit from and successfully lobby for protection. However, trade policy is a highly inefficient tool for redistributing income. Although recent theoretical research has focused on...

In this article, industrial evolution is driven by endogenous technology choices of firms, generating a rich environment that includes the possibility of a dramatic shakeout. The likelihood, magnitude, and timing of this shakeout are characterized and depend not only on the size of an innovation...
