The Coase Theorem Revisited: Implications for Economic Transition

This paper supports the view expressed by other authors that Ronald Coase’s ideas are often misrepresented in the academic world. It restates some of Coase’s main findings with special emphasis on their relevance to processes taking place in Eastern Europe. The goal of this paper is to revisit Coasean theory, to prove that oftentimes it is misrepresented and misinterpreted and to show its relevance to some societies experiencing high transaction costs. The role of the legal system under high transaction costs is stressed in its importance to transitional economies experiencing staggeringly high transaction costs. This paper tries to shed light on the importance of transaction costs in the newly emerging markets and the respective role courts and the government should play in directing economic resources.

我国热气商品成本价格现状及监审对策研究

城市供热包括热电公司向城镇居民提供热水、热气以及向城市有关部门提供蒸汽。我国城市集中供应蒸汽的数量近5年中平均每年以3.1%速度在下降,而同期集中供应热水总量平均每年以9.4%的速度在增长。而热气生产单位由于热气价格由政府控制,已大大低于其成本,出现亏损。亏损还来源于生产热气的原料煤价格上涨过快、热气输送管道(线)维修、维护费用升高等。政府为了保护城市居民的切身利益,往往采取一定方式对热气生产单位进行暗补。对热气商品成本进行监审既要政策法规制度进行,更重要的是对热气商品进行市场化改革,变暗补为明补,并在政策上予以引导。     

中国房地产开发及投资经济效应分析

房地产业在我国国民经济中处于举足轻重的地位,房价的大幅涨跌都会对经济运行造成严重影响。从微观角度,通过对地产开发成本费用的分析,发现以地价和税收为主的整个政府性费用支出占到了房地产开发费用支出的近50%,而房地产开发所得的销售收入中也有近1/3以上的销售收入流向政府。因此,抑制过热的房地产市场,控制不断高涨的房地产价格,政府肩负重要责任。从宏观角度,通过对辽宁省2005年一季度到2010年底二季度的GDP数据以及房地产投资季度数据的定量分析,发现房地产投资与经济增长之间的长期弹性为0.48,存在长期均衡关系。     

History-based price discrimination and entry in markets with switching costs: A welfare analysis

We analyze history-based price discrimination in an asymmetric industry, where an incumbent, protected by switching costs, faces an entrant who does not have access to information about consumers’ purchase histories. We demonstrate that consumer surplus is higher with uniform pricing than with history-based price discrimination. We find that the entry decision is invariant to whether the incumbent implements history-based pricing or uniform pricing. This implies that the potential abuse of market dominance imposed by history-based price discrimination is exploitation, not exclusion. Finally, we establish that the profit gain to the incumbent from history-based pricing exceeds the associated loss to consumers.     

税收遵从成本对企业纳税遵从的影响分析——基于企业逃税模型的视角

在传统的A-S逃税模型中加入税收遵从成本因素分析以及对纳税遵从的影响,只适用于个人纳税。运用企业逃税模型分析税收遵从成本对企业纳税遵从的影响不仅符合企业实际,而且在我国更有现实意义。当前,应完善税收征管,简化税制,优化税收环境,从根本上降低企业税收遵从成本。     

More on the role of switching costs in service markets: A research note

The present paper focuses on several important and under-researched issues related to switching costs (SC) as a defensive marketing tool in retaining customers with complaint handling. While most previous research analyzed the effects of SC on the behavioral intent of customers, our findings have focused on the actual behavior of bank customers; that is, staying with or leaving the bank to which they had complained previously. The findings show that, of the six potential facets of SC, only two significantly affect the actual behavior of complainants, one directly (i.e., Continuity Costs) and the other as a moderator (i.e., Learning Costs). Likewise, a customer's evaluation of the complaint handling affects behavior directly.     

农业生产的特殊性与农业生产组织的选择

在农业生产的纵向一体化演变过程中,专业合作社是取代家庭分立生产的主要模式。农业生产与工业生产相比,它的生物性特质成为影响农业生产组织选择的重要因素。从农业生产的特殊性出发,结合新制度经济学的企业理论,可以解释农业生产组织的演进特征。对我国而言,农户生产的专业化趋向以及土地改革的深化将将有利于农业专业合作社的进一步发展。     

Hub location problems in transportation networks

In this paper we propose a 4-index formulation for the uncapacitated multiple allocation hub location problem tailored for urban transport and liner shipping network design. This formulation is very tight and most of the tractable instances for MIP solvers are optimally solvable at the root node. While the existing state-of-the-art MIP solvers fail to solve even small size instances of problem, our accelerated and efficient primal (Benders) decomposition solves larger ones. In addition, a very efficient greedy heuristic, proven to be capable of obtaining high quality solutions, is proposed. We also introduce fixed cost values for Australian Post (AP) dataset.
