We present a two-country, two-good model in which there do not exist any markets for international trade in¯nancial assets. We compare the predictions of this model to those of two other models, one in which markets are complete and a second in which a single non-contingent bond is traded. Wē nd that only the¯nancial autarky model can generate volatility in the terms of trade similar to that in data for the°oating rate period and, at the same time, account for observed cross-country output, consumption, investment and employment correlations. We interpret our¯ndings as evidence that the extent of international borrowing and lending opportunities is important for the international business cycle.
We conduct a systematic empirical study of cross-sectional inequality in the United States, integrating data from the Current Population Survey, the Panel Study of Income Dynamics, the Consumer Expenditure Survey, and the Survey of Consumer Finances. In order to understand how different dimensions of inequality are related via choices, markets, and institutions, we follow the mapping suggested by the household budget constraint from individual wages to individual earnings, to household earnings, to disposable income, and, ultimately, to consumption and wealth. We document a continuous and sizable increase in wage inequality over the sample period. Changes in the distribution of hours worked sharpen the rise in earnings inequality before 1982, but mitigate its increase thereafter. Taxes and transfers compress the level of income inequality, especially at the bottom of the distribution, but have little effect on the overall trend. Finally, access to financial markets has limited both the level and growth of consumption inequality.
This paper explores the macroeconomic and welfare implications of the sharp rise in U.S. wage inequality . In the data, cross-sectional earnings variation increased substantially more than wage variation, due to a sharp rise in the wage-hours correlation. At the same time, inequality in hours worked and consumption remained roughly constant through time. Using data from the PSID, we decompose the rise in wage inequality into changes in the variance of permanent, persistent and transitory shocks. With the estimated changes in the wage process as the only primitive, we show that a standard calibrated OLG model with incomplete markets can successfully account for all these patterns in cross-sectional U.S. data. Through a set of counter-factual experiments, we assess the role of each component of the wage process for the evolution in the various dimensions of inequality. The model also allows us to investigate the welfare costs of the rise in inequality: we find that the unconditional expected welfare loss is equivalent to a 5 percent decline in lifetime income for the worst-affected cohorts, those entering the labor market in the mid 1980's. Ex post, these costs are widely dispersed across agents, due both to differences in permanent individual attributes and to differences in labor market histories. An extensive sensitivity analysis verifies the robustness of our results to alternative preferences and borrowing limits, and to the inclusion of female labor force participation.

Terms of use: Documents in AbstractWhat shapes the optimal degree of progressivity of the tax and transfer system? On the one hand, a progressive tax system can counteract inequality in initial conditions and substitute for imperfect private insurance against idiosyncratic earnings risk. At the same time, progressivity reduces incentives to work and to invest in skills, and aggravates the externality associated with valued public expenditures. We develop a tractable equilibrium model that features all of these trade-offs. The analytical expressions we derive for social welfare deliver a transparent understanding of how preferences, technology, and market structure parameters influence the optimal degree of progressivity. A calibration for the U.S. economy indicates that endogenous skill investment, flexible labor supply, and the externality linked to valued government purchases play quantitatively similar roles in limiting desired progressivity.
We combine publicly available data from Freddie Mac, the Decennial Census of Housing, and the Bureau of Economic Analysis to construct the first constant-quality aggregate price index for the stock of residential land in the United States. We uncover five main results: (a) since 1970, residential land prices have grown faster but (b) have also been twice as volatile as existing home prices; (c) averaged from 1970 to 2003, the nominal stock of residential land under 1-4 unit structures accounts for 38% of the market value of the housing stock and is equal to 50% of nominal annual GDP; (d) the real stock of residential land under 1-4 unit structures has increased an average of 0.6% per year since 1970; and (e) residential investment leads the price of residential land by three quarters. We also estimate that in 2003:Q3 the nominal value of the entire stock of residential land is the same as annual GDP. Finally, we show for the US data that the logarithms of the nominal price index for residential land, disposable income, and interest rates are cointegrated.
