We examine in detail the circumstances under which reciprocity, as defined in Bagwell and Staiger (1999), leads to fixed world prices. We show that a change of tariffs satisfying reciprocity does not necessarily imply constant world prices in a world of many goods and countries. While it is...

To the surprise of many, price deviations between markets characterized by imperfect competition have often been little affected by lower transport costs. In a Cournot model we show that if firms' decisions to segment markets are endogenous, then lower transport costs are, in many cases,...

This paper provides a new, unified, and flexible framework to measure and characterize a convergence process. Specifically, we formally define the notion of price convergence and propose a model to represent a wide range of transition paths that converge to a common steady-state. Our framework...

It is well known that business cycles in OECD countries exhibit a remarkable degree of synchronization. Much less known is that the peak of the OECD cycle is associated with high prices of labor-intensive products and low prices of capital-intensive ones. We document this cyclical behavior of...

This paper presents a stylized model of international trade and asset price bubbles. Its central insight is that bubbles tend to appear and expand in countries where productivity is low relative to the rest of the world. These bubbles absorb local savings, eliminating inefficient investments and...

We survey the recent empirical and theoretical developments in the literature on the relation between prices and exchange rates. After updating some of the major findings in the empirical literature, we present a simple framework to interpret this evidence. We review theoretical models that...

A market regime-switching model is developed that has rate of trade identified using a rent-weighted approach. The model also indirectly accounts for the impacts of other competitors through separate specifications of variation parameters across alternate seasons. Commodity futures prices are...
