Fiscal policy in the U.S. and other countries renders intertemporal budgets non-differentiable, nonconvex, and discontinuous. Consequently, assessing work and saving responses to policy requires global optimization. This paper develops the Global Life-Cycle Optimizer (GLO), a stochastic...

This paper compares two general methods of privatization social security: forced participation in the new privatized system vs. letting people choose between the new system or staying in social security (i.e., opting out). Simulations are performed using a large scale perfect-foresight OLG...

This paper uses the Auerbach-Kotlikoff Dynamic Life-Cycle Model (AK Model) to examine the macroeconomic and efficiency effects of privatizing social security, and a simple privatization proposal, the Personal Security System, to discuss other issues associated with privatization. According to...

This paper computes the expected present value of Social Security retirement benefits and taxes for households of different marital circumstances, incomes, and age cohorts. Also computed are the net gain or loss from participation in the system and the expected internal rate of return it offers...

The U.S. and other western economies are experiencing dramatic changes in growth and age structure of their populations. Fluctuations in birth rates are the most important determinants of these changes in the post war period. This paper examines the dynamic effects of baby "booms" and...

The effect of social security and other forms of government debt on national savings is one of the most widely debated policy questions in economics today. Some estimates suggest that social security has reduced U.S. savings by almost forty percent. This paper examines recent cross-section and...

This paper determines the standard of living reductions that young, middle aged, and older households would experience were the U.S. government to cut Social Security benefits (but not taxes) to deal with its well documented (see Gokhale and Smetters, 2005) long-term fiscal crisis. To determine...

Understanding how productivity varies with age is important for a variety of reasons. A decline in productivity with age implies that aging societies must increasingly depend on the labor supply of the young and middle age. It also means that policies designed to keep the elderly in the work...

Distingiishing "spot" versus "contract" views of the labor market is of critical importance to a host of economic issues ranging from wage flexibility over the business cycle to firm financial valuation. The structural features of U.S. private pension plans permit surprisingly strong inferences...

Does it pay to work? Given the number and complexity of federal and state tax and transfer systems, this is a tough question to answer. The problem is greatly compounded by the fact that what one earns in one year alters not just current taxes and transfer payments in that year, but in future...
