Site Summer Workshops in Theoretical Economics

这笔赠款为每年夏季斯坦福理论经济研究所(SITE)举办的年度经济理论夏季讲习班的参加者提供部分旅费援助。这个为期六周的研讨会汇集了知名学者和年轻的经济学家，介绍和讨论他们目前的研究。这一系列研讨会现已进入第29个年头，并继续成为研究经济理论和数理经济学创新主题的国际论坛。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年研讨会的一些主题，如一般均衡，是现场的长期利益。其他方面，如基于理论模型、计算方法和地方公共财政问题的实证工作，代表了SITE近年来采取的新方向，并预计将在未来几年继续下去。一般均衡模型继续在经济理论中具有重要意义和兴趣，并经常用于其他领域，如公共经济学和宏观经济学。最初，阿罗和德布鲁认为竞争市场是一套完整的状态或有商品和对称信息的市场。这是对实际市场经济的不切实际的描述，解释了人们对不完全市场的持续兴趣。SITE的目的是鼓励研究寻求对市场不完备性的理论解释，如果没有这样的研究，我们就缺乏一个适当的框架来分析旨在补救由此导致的低效的政策的影响。计算在经济分析中发挥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特别强调计算理论和实践，因为它是数理经济学中一个日益活跃的领域。例如，发展了动态随机竞争均衡模型的求解方法；数值泛函文献中的方法正被应用于动态模型，收敛和误差的算法已被评估；以及在具有多个代理人的动态经济的计算方法方面也有积极的工作。

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.
