This project examines a variety of dynamic problems in public finance, macroeconomics and industrial organization. In tax theory the project determines the characteristics of optimal taxation of capital and labor income, using nonlinear numerical techniques, and incorporating reasonable restrictions on government behavior. It also computes the political outcomes if governments cannot precommit to optimal policies. In industrial organization the project examines a dynamic model of oligopoly which allows firms to choose both quantities and prices, essentially merging the Bertrand and Cournot models. The dynamic model is used to examine the strategic importance of investment, learning, signalling and the incentives for merger. The project also develops numerical techniques which are necessary to examines these dynamic problems with general specifications of demand and supply. The research on tax policy is especially timely and important. The investigator's past work demonstrated that there are substantial differences between the results obtained from standard tax analysis and results from truly dynamic and stochastic models. This project establishes the robustness of the theoretical results by developing more realistic models. The loss due to nonoptimal rules is determined by comparing the optimal policy with alternatives.

该项目考察了公共财政、宏观经济和产业组织中的各种动态问题。在税收理论中，该项目利用非线性数值技术确定了资本和劳动收入的最优税收特征，并对政府行为进行了合理的限制。它还计算如果政府不能预先承诺最优政策的政治结果。在产业组织中，该项目考察了寡头垄断的动态模型，该模型允许企业选择数量和价格，本质上合并了贝特朗和古诺模型。动态模型用于考察投资、学习、信号和并购激励的战略重要性。该项目还开发了一些数值技术，这些技术对于用需求和供应的一般规格来检查这些动态问题是必要的。对税收政策的研究显得尤为及时和重要。研究者过去的工作表明，标准税收分析的结果与真正动态和随机模型的结果之间存在实质性差异。本项目通过建立更现实的模型来建立理论结果的稳健性。非最优规则的损失是通过比较最优策略和备选策略来确定的。
