We consider optimal fishery management under the assumption of increasing returns that is supported by previous empirical evidence. We improve the tractability and realism of the previous approaches by introducing flow adjustment costs on changes in harvest rate. Our framework is the first to...

Long-term observers of urban communities know that the housing quality distributions of communities and the changes of these distributions over time encompass not one but a variety of patterns. The equilibrium outcome derived from the housing market literature explains one pattern of change....

In this paper we study a capital accumulation model in an optimal control theoretic framework, where the capital stock and the investment rate are modeled as state variables and the change in the investment rate as control. Adjustment costs are introduced for both investment rate and the change...

A wealth of literature, reviewed in the first section of this paper, is concerned with the occurence of multiple equilibria in economic optimization models and with the resulting history dependence of optimal solutions. Typically, the existence of multiple equilibria is associated with market...

This paper presents techniques to solve for optimal simple monetary policy rules in rational expectations models. Both pre-commitment and discretionary solutions are considered. The techniques described are notable for the flexibility they provide over the structure of the policy rule being...

This paper is my ongoing research on welfare analysis using real business cycle approach. In this paper, I have modeled heterogeneous households with different income potential and paying different tax rates. The model incorporates progressive tax rates and computes its effects on the welfare of...

Dynamic models with inequality constraints pose a challenging prob- lem for two major reasons: Dynamic Programming techniques often necessitate a non established differentiability of the value function, while Euler equation based techniques have problematic or unknown convergence properties....
