We build a heterogeneous life-cycle model which captures a large number of salient features of individual labor supply over the life cycle, by education, both along the intensive and extensive margins. The model provides an aggregation theory of individual labor supply, firmly grounded on...

We develop a theory of educational quality to study how quality could account for schooling decisions regarding higher education (secondary and above), and how the distribution of educational attainment and educational quality differ with the level of development. In a general equilibrium closed...

The authors 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 the authors identify as banks, are endowed with the technology to issue notes and to record-keep reserves with a...

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...

This paper studies the role of social security and tax and transfer programs for understanding cross-country differences in labor supply late in the life cycle. First, we use the Survey of Health, Ageing, and Retirement in Europe (SHARE) as well as the U.S. Health and Retirement Study (HRS) to...

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...

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...

This paper presents evidence that the spread between the marginal product of capital and the return on financial assets is mich higher in poor than in rich countries. A model with costly intermediation is developed. In this economy, individuals choose at each instant whether to work or to...

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,...
