Dynamic coordination games

Summary Gains from coordination provide incentives for delay. In this paper, the extent of delay is studied in a dynamic,N-person, coordination game. There is no social gain from delay, so an equilibrium with delay is always inefficient. For fixedN, there is no coordination failure when the period length is short: all equilibrium outcomes converge to the Pareto efficient outcome as the period length converges to zero. On the other hand, holding period length fixed, there exist equilibria in which delay is proportional toN, for arbitrarily large values ofN. In addition, it can be shown that the possibility of delay depends on the timing of strategic complementarities. However, under certain conditions, delay is shown to be a robust phenomenon, in the sense that well-behaved equilibria exhibit infinite delay forN sufficiently large.This paper grew out of discussions with Christophe Chamley. While writing it I benefited from discussions with Ken Binmore, Russell Cooper, Bob Rosenthal and Michael Manove. Joe Farrell, Drew Fudenberg, Martin Hellwig and Sawoong Kang made very useful comments on an earlier version that led to substantial improvements. Helpful comments were also made by seminar participants at the London School of Economics, the SUNY at Stoney Brook, the NBER Summer Institute, Northwestern University, and the University of Chicago. I would like to thank Nick Yannelis and an anonymous referee for their editorial advice.

国际税收管辖权协调问题研究

本文介绍国际税收管辖权的三种形式以及国际上的有关处理方式,重点说明我国对此的认识和实践,提出在体现国际税收管辖权划分的政府间避免双重征税协定中,要以立足国情、维护国家权益为出发点,协调处理好缔约双方税收管辖权的关系。     

货币政策与宏观审慎政策的协调

本文在梳理学术文献和国际经验基础上,讨论了货币政策与宏观审慎政策之间的潜在冲突和协调机制。国际文献的初步结论是,为了同时实现价格稳定和金融稳定目标,大部分情况下需要货币政策与宏观审慎政策反向操作(由于政策的替代性),但有时也需要两者同向操作(由于政策的互补性),最优政策组合取决于宏观冲击的类别和风险的来源。本文认为,选择最优组合是一个复杂的理论和实证问题,除了冲击类别和风险来源外,不同的金融体制和经济周期阶段也会影响选择结果。因此,货币政策当局与宏观审慎当局之间需要建立有效的协调机制,并加强对货币政策和宏观审慎政策“溢出效应”的分析能力。基于上述理论,针对我国“双支柱”决策的现状和问题提出如下改革建议:一是从法律上明确中央银行的金融稳定职责。二是建立在同一框架内分析货币政策与宏观审慎政策的方法和工具。三是将金融监管部门的主要宏观审慎政策决策权集中至中央银行。四是建立货币政策与宏观审慎政策的协调流程与机制。     

中国农地产权绩效:来自制度匹配的观点

从"资源集中功能"和"生活保障功能"转向"经济激励功能"和"(市场)主体培育功能",进而转向"资源配置功能",这是我国集体土地产权模式经济功能的演变路径,它反映了不同阶段我国国民经济发展对集体土地产权制度的客观要求。基于制度匹配观点的分析表明:(1)从计划经济到市场经济的发展过程中,我国集体土地产权制度其实需要不同的制度匹配;(2)未来我国集体土地产权制度改革、户籍制度改革和公共服务供给制度改革必须联动进行。     

Balancing the sequential logic of quality constructs in manufacturing-supplier relationships — Causes and outcomes

Manufacturers in business markets are experiencing a strong trend towards close versus distant relationships with suppliers. Three key relationship constructs in academic research are trust, commitment, and satisfaction. Although the relevant literature holds some evidence that trust and commitment are antecedent to satisfaction, the possibility that satisfaction plays a key mediation role between trust/commitment and other important outcomes (i.e., coordination, cooperation, and continuity) receives scant examination. This study tests this conceptual model by examining the relationships between manufacturers and suppliers. A random sample of small-to-medium-sized Norwegian manufacturers was contacted by phone in order to identify potential key informants. Shortly thereafter, a total of 581 surveys were mailed to the key informants. Two hundred and twelve surveys were returned, representing a response rate of 36.5%. Results support the conceptual model presented; trust and commitment relate positively to satisfaction; and satisfaction, in turn, relates positively to all three outcomes of coordination, cooperation, and continuity.     

On the Effects of Suggested Prices in Gasoline Markets

There is a widespread suspicion that suggested prices act as a focal point for individual firms when setting their prices. Oil companies announce suggested prices for gasoline stations in the Dutch retail market. We show that, compared to the gasoline spot market price, suggested prices contain additional information that explains retail price changes. We conclude that suggested prices have a horizontal coordinating effect in the sense that retail prices react to information that suggested prices contain and that is unrelated to firms’ costs (i.e., the information that firms use under normal competitive conditions).     

Understanding overall output efficiency in public transit systems: The roles of input regulations,perceived budget and input subsidies

This paper examines the combined effects of subsidies, regulations and perceived budget on overall output and technical efficiency in a sample of single-mode bus transit systems using an indirect production function. The main findings are that the average transit system is 67.21% output efficient and systematic and stochastic technical inefficiencies decrease output. In addition subsidies increase output, regulations decrease output and the overall budget effect is an increase in output. Additionally, it identifies the characteristics of two groups of transit systems whose perceived costs after subsidies and regulations are either less or greater than actual total costs.     

Planning and developing tourism within a public sector quagmire: Lessons from and for small countries

This paper examined public sector tourism in Northern Ireland, a small country on the periphery of Western Europe which is notorious for being over-governed. The authors found that its complex web of public sector tourism bodies created confusion and duplication within the industry. There was a lack of coordination and clear policy guidelines and many of the organisations were suffering from ‘partnership overload’. To make matters worse for Northern Ireland its National Tourism Organisation, faced with a reduced remit and shrinking budget, was not capable of making decisions and providing the strategic leadership that is required to drive the tourism agenda forward. Northern Ireland, and indeed any small country involved in tourism, could learn valuable lessons from Northern Ireland’s Celtic neighbours, Scotland, Wales and the Republic of Ireland, countries which have taken action to remove some of their layers of administration and bureaucracy and make public sector tourism more streamlined and manageable.
