This paper provides an empirical analysis of how the U.S. Social Security and Medicare system affects the labor supply of older males in the presence of incomplete markets. The authors estimate a dynamic programming model of the joint labor supply and Social Security acceptance decision. The...

This paper introduces a new detailed data set of high-frequency observations on inventory investment by a U.S. steel wholesaler. Our analysis of these data leads to six main conclusions: orders and sales are made infrequently; orders are more volatile than sales; order sizes vary considerably;...

This paper analyzes the asymptotic convergence properties of policy iteration in a class of stationary, infinite-horizon Markovian decision problems that arise in optimal growth theory. These problems have continuous state and control variables, and must therefore be discretized in order to...

We construct a stochastic dynamic programming model as the basis of an empirical framework within which to examine the effects of different sequences of work and rest on the daily productivity of workers who planted trees in the province of British Columbia, Canada, comparing the intertemporal...

We present a dynamic extension of the classic static model of Bertrand price competition that allows competing duopolists to undertake cost-reducing investments in an attempt to “leapfrog” their rival to attain low-cost leadership—at least temporarily. We show that leapfrogging occurs in...
