In this paper we theoretically and empirically model import demand and export supply behavior of firms for the U.S. economy from 1967-1982. A producer theoretic approach based on duality theory is used to derive econometric systems of producer supply and demand functions that are consistent with...

We build a quantitative model of trade with multistage manufacturing value chains, which features iceberg trade costs and technology differences across both goods and production stages. We estimate technology and trade costs via the simulated method of moments, matching bilateral shipments of...

Tradeoffs between monetary wealth and fatal safety risks are summarized in the value of a statistical life (VSL), a measure that is widely used for the evaluation of public policies in medicine, the environment, and transportation safety. This paper demonstrates the widespread use of this...

This paper examines the stability of import and export demand functions for the United States over the 1975q1-2001q2 period. Using the Johansen maximum likelihood approach, an export demand function is readily identified. In contrast, there appears to be a structural break in the import demand...

This paper argues that the theoretical foundations for the gravity equation are general, while the empirical performance of the gravity equation is specific to the type of goods examined. Most existing theory for the gravity equation depends on the assumption of differentiated goods. We show...

In this paper, a structural gravity model is presented which features intra-sector heterogeneity in agricultural productivity systematically linked to land and climate characteristics. The "systematic heterogeneity" (SH) gravity model predicts that countries with similar land and climate...

We use micro data for Ireland to estimate how export participation and the export revenue of incumbent exporters respond to tariffs and real exchange rates. Both participation and revenue, but especially revenue, are more responsive to tariffs than to real exchange rates. Our estimates translate...

We develop a Ricardian model to explore the role of trade in spreading the benefits of" innovation. The theory delivers an equation for bilateral trade that gravity specification, but identifies underlying parameters of technology. We estimate the" equation using trade in manufactures among the...
