We propose a short-run model of the extensive margin of trade and deploy it to distinguish and quantify domestic and cross-border margins. Our empirical focus is on the domestic extensive margin of trade (domestic distribution of a product) and its importance for quantifying policy and...

Starting with Romer [1987] and Rivera-Batiz-Romer [1991] economists have been able to model how trade enhances growth through the creation and import of new varieties. In this framework, international trade increases economic output through two channels. First, trade raises productivity levels...

This paper examines the relative "sophistication" of China's exports to the United States along two dimensions. First, I compare China's export bundle to those of the relatively skill- and capital-abundant members of the OECD as well as to similarly endowed U.S. trading partners. Second, I...

This paper deals with the role of trade regimes in determining economic performance and growth in the developing countries. The policy and empirical literatures on trade orientation and economic growth are critically reviewed; it is argued that a key limitation of these works has been the...

Japanese exports between 1880 and 1910 increased massively in volume, changed composition, and shifted away from leading industrialized countries toward poorer Asian neighbors. The product mix also varied with the level of development of the destination, with new products and specializations...

Does corporate diversification reduce shareholder value? Since firms endogenously choose to diversify, exogenous variation in diversification is necessary in order to draw inferences about the causal effect. We examine changes in the within-firm dispersion of industry investment, or diversity.'...

This paper examines the extent to which permanent terms-of-trade shocks have an asymmetric effect on private savings. The first part uses a simple three-period model to show that, if households expect to face binding borrowing constraints in bad states of nature, savings rates will respond...

The paper extends previous analysis of closed-economy inflation targeting to a small open economy with forward-looking aggregate supply and demand with some microfoundations, and with stylized realistic lags in the different transmission channels for monetary policy. The paper compares targeting...
