Since the early 1980s, the U.S. economy has experienced a growing wage differential: high-skilled workers have claimed an increasing share of available income, while low-skilled workers have seen an absolute decline in real wages. How and why this disparity has arisen is a matter of ongoing...

We use the structure of the Melitz (2003) model to compare the cost of living and welfare across countries, while incorporating product variety measured by the count of barcodes or firms. For 47 countries, we compare welfare relative to the United States to conventional measures of real...

Many price indices must be constructed without quantity data at the elementary level. We show that for some consumer goods in the United States and other countries, one can approximate expenditure shares using weights derived from the retail distribution of sellers. These weights are based on...

Among the interesting changes in the U.S. economy in recent years have been the substantial changes in the age distribution of income and its components. These changes are interesting in and of themselves, but also are an important background against which to interpret aggregate economic...

The substantial post war decline in the U.S. saving rate has added great impetus to the debate over whether public debt policy crowds out saving. Rather than attempting to reject specific saving models, empirical research on debt policy and savings has primarily focused on the impact of...

This paper develops a general equilibrium two country, two commodity dynamic simulation model of international trade in commodities and financial claims. The model generalizes the Heckscher-Ohlin static theory of trade by incorporating costs of quickly adjusting levels of capital stocks in...

The 'China shock' operated in part through the housing market, and that is an important reason why the China shock was as big as it was. If housing prices had not responded at all to the China shock, then the total employment effect of the China shock would have been reduced by more than...

This paper is the first attempt to structurally estimate the impact of globalization on markups, and the effect of changing markups on welfare, in a monopolistic competition model. To achieve this, we work with a class of preferences that allow for endogenous markups and firm entry and exit that...

Since 1995, growth in productivity in the United States appears to have accelerated dramatically. In this paper, we argue that part of this apparent speed-up actually represents gains in the terms of trade and tariff reductions, especially for information-technology products. We demonstrate how...

China eventually becomes the world's saver and, thereby, the developed world's savoir with respect to its long-run supply of capital and long-run general equilibrium prospects. And, rather than seeing the real wage per unit of human capital fall, the West and Japan see it rise by one fifth by...
