Free-Trade Areas and Welfare: An Equilibrium Analysis

This paper examines the welfare effects of the formation of a free-trade area. When a country is constrained to charge lower tariffs on imports from some countries, it is in its interest to reduce external tariffs as well. In alinear-quadratic model of intraindustry trade, the reduction in external tariffs induced by free-trade agreements is sufficiently large to make nonmember countries better off. Since only privately beneficial free-trade agreements are signed voluntarily, the formation of a free-trade area is a Pareto improvement. Owing to free-riding problems, however, the global free-trade area may not be a stable outcome.     

Reforming Social Welfare in Germany: An Applied General Equilibrium Analysis

Abstract. In this paper, the effects of social assistance reform proposals are discussed for the case of Germany using a computable general equilibrium model that incorporates a discrete choice model of labour supply. This allows us to identify general equilibrium effects of the reforms on wages and unemployment. The simulation results show that general equilibrium wage reactions mitigate labour supply effects and that unemployment in fact decreases. Wage reactions are thus sufficiently strong to prevent additional labour supply from translating into higher unemployment. The simulations indicate that major cuts in welfare payments are necessary to produce substantial employment effects.     

Migration, Jobs and Welfare: A General Equilibrium Analysis

Immigration has been an important element of the economic development of many countries, although in recent years there has been an intensification of doubts about the benefits of further immigration. This paper brings some simple general‐equilibrium modelling tools to bear on the question of the employment and welfare effects of immigration. Employment and taxation effects, rather than wage and distributional effects, are found to be crucial in determining the impact of immigration on the welfare of factor‐owners in the receiving country. These employment effects depend on the type of immigration and the substitutability or complementarity relationships between immigrant labour and unemployed labour. Certain types of immigration are shown to be Pareto‐improving for the receiving country, without any need for lump‐sum transfers. Simple numerical simulations illustrate the results.     

The Optimality of Arbitrary Partial Equilibrium Welfare Analysis

This paper characterizes the general equilibrium foundation of arbitrary partial equilibrium welfare analysis in second‐best economies. While prior theory recognizes the importance of market distortions affected by relative price changes, it offers little guidance about the necessary scope of Marshallian partial equilibrium analysis. The paper determines necessary and sufficient conditions for optima of Marshallian total surplus functions to characterize second‐best Pareto‐optimal allocations. While these conditions confirm much of the traditional approach to applied welfare economics, they bring doubt about its reliability for public policy and concerns over its systematic use to build conventional economic wisdom.     

Voluntary Export Restraints and Economic Welfare: A General Equilibrium Analysis

We derive some sufficient conditions for the Suzumura-Ishikawa proposition on voluntary export restraints to hold when their model is extended to a general equilibrium framework. The sufficient conditions are concerned with the magnitude of income effects which play no role in the partial-equilibrium analysis of Suzumura and Ishikawa.     

An Index of Segmentation in Local Labour Markets

This study tests for the existence of labour market segmentation by exploiting the variation in industrial structure across 59 labour market areas, as defined by MSAs. By creating an index of the relative explanatory power of standard and segmented earnings function models for each area, empirical evidence supports the hypothesis that segmentation exists and that the index reflects the degree of segmentation in local labour market areas.     

Resource Rights and Markets in a General Equilibrium Model of Production

Rights to a free resource lead to distributional deadweight losses in partial equilibrium. The present paper examines related distortions in a general equilibrium model of production with output prices constant for the small open economy. The free resource can result in lower output than a market with weak substitution in the other sector. The free resource also leads to a convex production frontier implying a price increase lowers output in the sector. Regarding policy, an import tariff, export subsidy, or price support would lower sector output. These general equilibrium distortions increase the incentives to favor resource markets over rights.     

市场结构、环境税与福利效应分析

运用短期局部均衡分析方法研究完全竞争市场和垄断市场条件下环境税对社会福利的影响.结果显示:在完全竞争市场条件下,对企业征收环境税可以增进社会福利.而在垄断市场条件下,环境税的福利效应具有不确定性,这取决于垄断造成的扭曲程度.如果垄断造成的扭曲较小,环境税仍然可以提高社会福利.但无论是增进抑或降低社会福利,对垄断企业征收环境税都不可能实现最优化,因为环境税在矫正污染外部性的同时,垄断造成产量水平下降导致福利损失增加,所以只能追求一个次优的结果,次优环境税低于完全竞争条件下的标准环境税.

中国地方官员的晋升锦标赛模式研究

本文研究了中国地方官员的治理模式——"晋升锦标赛治理模式"的性质与特征,并试图揭示这种特定模式与中国高速经济增长及其各种特有问题的内在关联。本文认为,晋升锦标赛作为中国政府官员的激励模式,它是中国经济奇迹的重要根源,但由于晋升锦标赛自身的一些缺陷,尤其是其激励官员的目标与政府职能的合理设计之间存在严重冲突,它目前正面临着重要的转型。     

Multivariate Analysis of the Condition of the Property Development Sector: Selected Local Real Estate Markets in the European Union

The aim of the study is to serve as a multidimensional analysis of relationships between the economic and financial standing of property developers and the residential property market situation. The discussion concerns the property development market situation in the context of the construction market situation, with particular emphasis on residential housing investment in selected EU countries. Property development companies whose activities focused on residential housing were assessed with respect to performance in the selected market on the stock exchange. Individual companies were classified using economic and financial indices. Despite the ongoing economic downturn in real estate markets, the results for these companies did not indicate poor performance on the stock exchange. In the study, a synthetic measure of development was used in linear ordering.     

Estimating Households' Preferences for Environmental Amenities Using Equilibrium Models of Local Jurisdictions

Much research has focused on the development of equilibrium models of local jurisdictions to analyze the formation of social structures and community characteristics. These models, however, have been subjected to little empirical testing. In a recent paper, Epple and Sieg (1999) developed a new method for estimating equilibrium models of local jurisdictions, but they did not include environmental amenities in their empirical application. In this paper, we extend and apply this new method to estimate households’ preferences for alternative environmental amenities in the Portland Oregon metropolitan area. We show that estimated structural parameters would be biased if environmental amenities are ignored. By including amenities into the structural models of local jurisdictions, households’ preferences for alternative environmental amenities and public goods are estimated. Parameter values underlying households’ residential choices are uncovered. Many of the empirical regularities observed in the data are replicated (JEL R1, R2, Q2).     

Providing Duty-Free Access to Australian Markets for Least-Developed Countries: A General Equilibrium Analysis

The Doha ministerial declaration commits WTO members to liberalising access to their markets for least‐developed countries (LDCs). Preferential trade policies have diverse impacts on the initiating country and its trading partners. These effects are of concern to scholars and policy makers. We use Australia as a case study to quantify the direct and indirect effects of providing preferential access to LDC imports entering Australian markets, using a general equilibrium model of the world economy. LDCs are projected to benefit and Australia is predicted to lose, reflecting adverse terms of trade effects. However, the magnitude of the adverse effect on Australia is small. If one was to view this initiative as an exercise in foreign aid, it suggests that Australia can provide a significant benefit to the poorest nations with which it trades, at almost no cost to itself.     

An Empirical Examination of Entry Patterns in Local Telephone Markets*

In this analysis we examine the market entry patterns of new local telephone companies. We construct and estimate a multinomial logit model using information describing numbering code distribution within local telephone markets and the associated income, density, and regulatory characteristics of these markets. Our findings support the conventional wisdom that facilities-based entry by new local competitors is more likely to occur in large urban telephone markets. In addition, we present evidence that, with the exception of territories served by Ameritech, entry is more likely to occur in Bell Operating Company service territories.     

浅析知识产权保护中混合策略纳什均衡模型的应用

知识产权保护不但受制于立法的完善和执法的力度,而且取决于自觉维权的意识和守法的环境。我国企业和科研机构知识产权保护意识薄弱,缺乏维护自身合法权益的能力,尊重他人知识产权的观念尚未形成社会主流。本文运用博弈论方法,分析了一个知识产权保护博弈案例中的混合策略纳什均衡解,得出从增加知识产权主体自觉维权意识和加大侵权者成本两方面实现知识产权有效保护的结论。     

商业银行行为与资产市场泡沫--一个基于中国制度背景的均衡模型

资产市场均衡价格高于其真实价格的部分即为泡沫,泡沫破灭将导致财富幻觉的消失,进而造成需求萎缩、投资不足、经济增长放缓等不良后果.文章研究表明,制度缺陷将导致资产市场理性泡沫的存在.在资产市场配额供给、商业银行承担两类代理成本、央行实施价格管制、监管当局实施资产比例管理等制度背景下,存在私人利益和正的边际私人利益的银行家,倾向于向资产市场过度供给贷款,从而导致风险资产价格相对于银行家无私人利益时的均衡资产价格而言,系统性地被高估.在商业银行与银行监管当局仅根据风险资产最近成交价格预测银行贷款组合或贷款低押物未来价值这一信息结构下,一次交易中所形成的资产市场泡沫,可能会随着时间的延续而逐渐累积.
