Site Summer Workshops in Theoretical Economics

该补助金为参加斯坦福大学理论经济学研究所（SITE）每年夏季举办的年度经济理论夏季讲习班的参与者提供部分旅费援助。这个为期六周的研讨会汇集了杰出的学者以及年轻的经济学家，介绍和讨论他们目前的研究。该研讨会系列现已进入第29个年头，并继续作为经济理论和数理经济学创新主题研究的国际论坛。斯坦福大学为该项目提供全面的行政支持和设施。考虑列入1999年讲习班的一些专题，如一般均衡，是发展和贸易效率服务基础设施司的长期兴趣所在。另外，以理论模型、计算方法、地方财政问题为基础的实证研究等，是近年来研究的新方向，今后也将继续研究。一般均衡模型在经济理论中仍然具有重要意义，在公共经济学、宏观经济学等其他领域也经常使用。最初，阿罗和德布鲁考虑了一整套国家或有商品的竞争市场，以及对称信息。这是对实际市场经济的不切实际的描述，解释了对不完全市场的持续兴趣。SITE的目标是鼓励研究，寻求市场不完全性的理论解释，没有这些解释，我们就缺乏一个适当的框架来分析旨在纠正随之而来的低效率的政策的效果。计算在经济分析中起着越来越重要的作用。经济学家和数学家正在开发算法来计算日益复杂的经济模型的均衡。SITE选择计算理论和实践作为特别重点，因为它是数理经济学中日益活跃的领域。例如，开发了动态随机竞争平衡模型的求解方法;将数值泛函文献中的方法应用于动态模型，评估了算法的收敛性和误差;还积极研究了具有许多代理人的动态经济的计算方法。

This grant provides partial assistance with travel expenses of participants in the annual Summer Workshops on Economic Theory conducted each summer by the Stanford Institute of Theoretical Economics (SITE). This six-week collection of workshops brings together prominent scholars as well as younger economists for presentation and discussion of their current research. This workshop series is now in its 29th year and continues to serve as an international forum for the study of innovative topics in economic theory and mathematical economics. Stanford University provides full administrative support and facilities for the program. Some topics considered for inclusion in the 1999 workshops such as general equilibrium, are long-term interests of SITE. Others, such as empirical work based on theoretical models, computational methods, and issues in local public finance, represent new directions that SITE has taken in recent years and expects to continue in future years.General equilibrium models continue to be of great importance and interest in economic theory, and are frequently used in other fields, such as public economics and macroeconomics. Originally Arrow and Debreu considered competitive markets for a complete set of state contingent commodities, and symmetric information. This is an unrealistic description of actual market economies that explains the continuing interest in incomplete markets. SITE's aim is to encourage research that seeks theoretical explanations of market incompleteness, without which we lack a proper framework for analyzing the effects of policies designed to remedy the consequent inefficiencies. Computation is playing an increasingly important role in economic analysis. Economists and mathematicians are developing algorithms to compute equilibria of increasingly complex economic models.SITE has selected computational theory and practice for special emphasis because it is an increasingly active field in mathematical economics. For example, solution methods for dynamic stochastic competitive equilibrium models were developed; methods from the numerical functional literature are being applied to dynamic models, algorithms for convergence and errors have been evaluated; and there is also active work on computational methods for dynamic economies with many agents.
