This paper shows that in a life-cycle framework, the optimal tax on capital crucially depends on how human capital is accumulated. We focus on three cases common to the macroeconomic literature: (i) Learning-By-Doing (LBD), (ii) Learning-Or-Doing (LOD), and (iii) exogenous accumulation. First,...

A well-established result in the literature is that Social Security tends to reduce steady state welfare in a standard life cycle model. However, less is known about the historical effects of the program on agents who were alive when the program was adopted. In a computational life cycle model...

Previous literature demonstrates that in a computational life cycle model the optimal tax on capital is positive and large. Given the computational complexities of these overlapping generations models it is helpful to determine the relative importance of the economic factors driving this result....

This paper considers the impact on optimal tax policy of including endogenously determined retirement in a life cycle model. Allowing individuals to determine when they retire causes the optimal tax on capital to increase by 75% because of two implicit changes in the aggregate labor supply...

There are large differences between the microeconometeric estimates of the Frisch labor supply elasticity (0-0.5) and the values used by macroeconomists to calibrate general equilibrium models (2-4). The microeconometric estimates of the Frisch are typically estimated by regressing changes in...
