In this article, we consider a knowledge accumulation problem within an organization that cannot prevent the worker from quitting and using the knowledge outside the organization. We show that knowledge accumulation is delayed: The fraction of working time allocated to knowledge creation is...

We investigate economic depreciation of natural capital for cases of nonstationary output prices, technology, and interest rates. For the former two cases (exogenous movements in prices and technology), constant consumption emerges under a strategy of investing to cover off economic...

We analyze a class of two-stage games where rival firms incur real resource costs in manipulating their marginal costs, so as to influence the outcome of the game they want to play in stage two. Marginal costs may be manipulated by various means, such as redistribution of productive assets,...

The authors study optimal nonrenewable resource royalty contracts when the extracting agent has private information on costs. This is a dynamic incentive problem in which the repeated relationship between the principal and the agent is constrained by initial reserves. Commitment is limited to...

Consider the optimal time path of a tax on capital income, the proceeds of which are transferred to labor in a lump sum. It is known from earlier open-loop formulations that, if the optimal rate of tax converges to a point, it converges to zero, implying that, in the long run, a tax on capital...
