Understanding Earnings, Labor Supply, and Retirement Decisions

We develop and estimate a model in which individuals make decisions on consumption, human capital investment, labor supply, and retirement. Unlike all previous work, our model allows both an endogenous wage process (which is typically assumed exogenous in the human capital and earnings dynamics literature). In addition, we introduce health shocks. We estimate the model and match the life-cycle profiles of wages, hours and retirement from SIPP data. We analyze the impact of health shocks on retirement, as well as the effect of changes in payroll taxes and increases in the Normal Retirement Age on labor force participation of older Americans.
