This paper examines the role of lumpy consumer durables and market power in generating endogenous cycles which seem to be consistent with the facts. When goods are durable, past consumption choices determine the current market size which consists of consumers who have not purchased the good...

Income disparity across countries has been large and widening over time. We develop a tractable model where factor requirements in production technology do not necessarily match a country's factor input profile. Appropriate assimilation of frontier technologies balances such multi-dimensional...

This paper develops tools and techniques to study the impact of exogenous changes in factor supply and factor demand on factor allocation and factor prices in economies with a large number of goods and factors. The main results of our paper characterize sufficient conditions for robust monotone...

The extent to which like-with like marry is important for inequality as well as for the outcomes of children that result from the union. In this paper we present evidence on changes in assortative mating and its implications for household inequality in the UK. Our approach contrasts with others...

We analyze how relative wage movements across birth cohorts and education groups during the 1980s affected the distribution of household consumption. The analysis integrates the labor economics literature on time variation in the wage structure with the consumption insurance literature. In...

Recent research has documented that income inequality in the United States has increased dramatically over the prior three decades. There has been less of a consensus, however, on whether the increase in income inequality was matched by an equally large increase in consumption inequality. Most...

Using longitudinal data for 1968-2009 for male household heads, we determine the prevalence of pre- retirement age disability and its association with a wide range of outcomes, including earnings, income, and consumption. We then employ some of these quantities in the optimal social insurance...

Earnings dynamics are much richer than typically assumed in macro models with heterogeneous agents. This holds for individual-pre-tax and household-post-tax earnings and across administrative (Social Security Administration) and survey (Panel Study of Income Dynamics) data. We estimate two...
