Optimal taxation in life-cycle economies
We use a very standard life-cycle growth model, in which individuals have a labor-leisure choice in each period of their lives, to prove that an optimizing government will almost always find it optimal to tax or subsidize interest income. The intuition for our result is straightforward. In a life-cycle model the individual?s optimal consumption-work plan is almost never constant and an optimizing government almost always taxes consumption goods and labor earnings at different rates over an individual?s lifetime. One way to achieve this goal is to use capital and labor income taxes that vary ...

Private money and reserve management in a random matching model
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 central clearinghouse, which they call the treasury. The liabilities are redeemed according to a stochastic process that depends on the endogenous trades. The treasury removes the banking technology from banks that are not able to meet the redemptions in a given period. This, together with the market ...

Private money and reserve management in a random-matching model
In this paper, we develop a model of money and reserve-holding banks. We allow for private liabilities to circulate as media of exchange in a random-matching framework. Some individuals, which we identify as banks, are endowed with a technology to issue private notes and to keep reserves with a clearinghouse. Bank liabilities are redeemed according to a stochastic process that depends on the endogenous trades. We find conditions under which note redemptions act as a force that is sufficient to stabilize note issue by the banking sector.

A general equilibrium analysis of parental leave policies
An important feature of the U.S. labor market is that, even after controlling for measurable differences in education and experience, the average wage of women with children is 89 percent of the average wage of women without children. This "family gap" in wages accounts for almost half the gender gap in wages. Proponents of mandatory-leave policies argue that career interruptions associated with fertility have long-lasting effects on female employment and are costly in terms of human-capital losses for females. Despite the fact that mandatory leaves are widely applied in developed ...

On the aggregate and distributional implications of productivity differences across countries
We develop a quantitative theory of human capital with heterogeneous agents in order to assess the sources of cross-country income differences. The cross-sectional implications of the theory and U.S. data are used to restrict the parameters of human capital technology. We then assess the model's ability to explain the cross-country data. Our quantitative model generates a total-factor-productivity (TFP) elasticity of output per worker of 2.8. This implies that a factor of 3 difference in TFP is amplified through physical and human capital accumulation to generate a factor of 20 difference in ...

A quantitative theory of the gender gap in wages
Using panel data from the National Longitudinal Survey of Youth (NLSY), we document that gender differences in wages almost double during the first 20 years of labor market experience and that there are substantial gender differences in employment and hours of work during the life cycle. A large portion of gender differences in labor market attachment can be traced to the impact of children on the labor supply of women. We develop a quantitative life-cycle model of fertility, labor supply, and human capital accumulation decisions. We use this model to assess the role of fertility on gender ...
