We introduce an element of centralization in a random matching model of money that allows for private liabilities to circulate as media of exchange. Some agents, which we identify as banks, are endowed with the technology to issue notes and to record-keep reserves with a central clearinghouse,...

Then, we build a theory of labor supply with heterogeneous agents consistent with these empirical facts.  The key features of the model are life-cycle, incomplete markets, nonlinear wage schedules, an intensive and extensive margin in labor supply, and a social security system.  We calibrate...

In this paper, we first use household survey data to documents facts on the heterogeneity and life-cycle dynamics of labor supply across many European countries and the U.S. We also document a substantial variation in the out-of-pocket medical expenses faced by individuals across countries. We...

This paper has three contributions. First, we document various facts about the labor supply decisions of men and women in the US over their life-cycle. For cohorts of male and female individuals in the PSID, we study the life-cycle profile of average hours worked, the variance of log hours, and...

human capital understates differences across countries by a factor of 2.

We develop a quantitative life-cycle theory of occupational choice decisions, economic inequality, and financial frictions. The model is calibrated to life-cycle evidence on occupational choices and their persistence, earnings inequality, and consumption inequality in the Brazilian data. An...

There is a negative mean-dispersion relationship between the log of mean annual hours in an occupation and the standard deviation of log annual hours in that occupation. We document this pattern using data from the 1976-2011 Current Population Survey (CPS) and various Survey of Income and...
