The paper examines optimal annuitization for retirees with potential post-retirement work.

problem Post-retirement labor participation complicates optimal annuitization decisions.
method Stochastic control, optimal stopping, expected utility maximization, martingale methodology, duality techniques.
result The optimal annuitization time is linearly dependent on initial wealth, with or without labor income.

Labor productivity in developed countries is analyzed and modeled. Modeling is based on our previous finding that the rate of labor force participation is a unique function of GDP per capita. Therefore, labor productivity is fully determined by the rate of economic growth, and thus, is a secondary economic variable. In…
