股权再融资、盈余管理与大股东的寻租行为

我国上市公司处于大股东的超强控制状态,大股东与中小股东之间存在严重的信息不对称,导致大股东在股权再融资过程中表现出强烈的盈余管理动机.本文研究了我国资本市场参与者的行为与盈余管理之间的关系,并分析了对资本配置效率的影响效应.大股东通过操纵报告盈余来改变会计盈余的时间分布和误导投资者,从而攫取更多的隐性收益,造成资本市场配置效率的降低.研究结果表明:(1)大股东通过盈余管理在股权再融资过程中可以获得中小股东无法得到的隐性收益;(2)大股东的收益随着盈余管理程度的增加而提升,中小股东的财富随着盈余管理程度的增加而降低;(3)盈余管理程度的增加将降低上市公司的资本配置效率和企业价值.因此,大股东通过盈余管理实现了对小股东财富的掠夺效应,造成了上市公司资本配置效率、公司价值、声誉和后续融资能力的下降.     

Market power and rents in global supply chains

Market power and competition policy in food supply chains has emerged as an important economic issue in economics, and a highly sensitive item on the policy agenda. Consolidation is taking place in the food industry, both in high‐income countries and in emerging economies, but the impact of concentration in global food chains on efficiency and rent distribution is more nuanced and complex than often claimed. We review the literature and extend it by developing a model which explicitly takes into account market imperfections and contract enforcement problems in supply chains. Increased competition benefits farms by improving contract conditions, but contract enforcement becomes more complicated.     

银行监管的法价值追求

经济在发展,法价值追求并非是一成不变的。从美国银行监管的历史可以看到,银行监管法律制度的核心价值由单一的追求效率变为单一的寻求安全,再转向有安全保障的效率优先;从银行监管的法价值角度分析,效率、安全和公平是银行监管的法价值追求,银行监管的具体措施都应体现出兼顾效率、安全和公平,以效率优先的价值追求,且三者的地位随着银行业运行态势的变化而逐步变化。     

The Terms of Trade and the International Transfers of Productivity Gains

In international economic relations, when movements of labour are limited and fiscal redistributive policies non-existent, changes in the terms of trade (the ratio between the prices of exports and imports) are the main driving force for the international redistribution of incomes or of productivity gains. The concept of productivity flows linked to price changes can be extended from the interindustry framework to deal with international relations bringing some new insights into the terms of trade issues. The paper develops a conceptual framework for the computation of international flows of productivity gains, taking into consideration the role of exchange rates and the meaning of Purchasing Power Parities. It is completed by a set of computations on Swiss relations with the rest of the world.     

我国房地产市场的泡沫检验——基于现值模型

本文以35个大中城市指数为基础,利用现值模型对我国东中西部地区房地产市场泡沫的存在性进行了检验.检验结果表明,我国东部和西部地区存在明显的房地产泡沫,其中东部特别是长江三角洲地区的房价租金比涨幅最大.而中部地区除武汉之外的房价租金比一直较为平稳,几乎不存在泡沫现象.     

Preemptive entry in differentiated product markets

Summary. Models of spatial competition are typically static, and exhibit multiple free-entry equilibria. Incumbent firms can earn rents in equilibrium because any potential entrant expects a significantly lower market share (since it must fit into a niche between incumbent firms) along with fiercer price competition. Previous research has usually concentrated on the zero-profit equilibrium, at which there is normally excessive entry, and so an entry tax would improve the allocation of resources. At the other extreme, the equilibrium with the greatest rent per firm normally entails insufficient entry, so an entry subsidy should be prescribed. A model of sequential firm entry (with an exogenous order of moves) resolves the multiplicity problem but raises a new difficulty: firms that enter earlier can expect higher spatial rents, and so firms prefer to be earlier in the entry order. This tension disappears when firms can compete for entry positions. We therefore suppose that firms can commit capital early to the market in order to lay claim to a particular location. This temporal competition dissipates spatial rents in equilibrium and justifies the sequential move structure. However, the policy implications are quite different once time is introduced. An atemporal analysis of the sequential entry process would prescribe an entry subsidy, but once proper account is taken of the entry dynamics, a tax may be preferable.

Political Economy of Industrial Development in Vietnam’s Telecommunications Industry: A Rent Management Analysis

This article contributes to the current debate in economics on the uses and benefits of rents and rent seeking. On the one hand, public choice and neoliberal scholars highlight the redistributive and damaging aspects of rent seeking, thus rendering the policy suggestion to completely eradicate rents and rent seeking in an economy. On the other hand, institutional and development economists point out the inherent theoretical inconsistencies shown in the earlier models, and suggest that certain types of rent and rent seeking could be growth-enhancing. Using the Developmental Rent Management Analysis, this article assesses the industrial development of the telecommunications industry in Vietnam using two case studies. Qualitative research points out a number of rent management factors contributing both to the industry’s failure before the early 2000s and its subsequent success thereafter. The successful development of the telecommunications industry was fundamentally based on (i) favorable political support for rent creation, (ii) an effective structure of rent allocation and implementation, and (iii) credible incentives and pressures that encouraged local firms’ industrial upgrading. The Vietnamese experience suggests that rents can be developmental, conceivably side-by-side with rent seeking, cronyism and corruption.     

公共租赁住房成本租金与定价研究

完善公共租赁住房定价机制是保持公共租赁住房建设与管理可持续发展的重要内容。本文在实地调研杭州、湖州、嘉兴、绍兴、台州、丽水等地区公共租赁住房开发成本状况的基础上,选取了较有代表性的几个地区,对公共租赁住房的成本租金进行了测算,并通过比较公共租赁住房租金定价的国际经验,对浙江省公共租赁住房的租金定价提出了建议。     

产权界定、市场禁入与农村非正规金融——由我国第一家私人钱庄兴衰引发的思考

通过对改革开放后第一家私人钱庄兴衰的史实进行重新考察和审视,本文经研究发现,尽管权力当局把资金自由交易权界定给了监管部门,但因监管成本和信息成本过高而无法保障该产权,个人会通过参与各类非正规金融活动来攫取一部分置于公共领域的权利。本文还基于交易费用理论解释了我国金融市场禁人政策出现松动的原因,也即维持扭曲型二元金融制度的成本以及严禁农村非正规金融活动的费用都越来越高,而且国内的经济形势也提出了放松监管的要求,在这些因素的作用下监管部门执行原有金融抑制政策的力度终于降低了。     

战后日本实现金融深化的路径分析

战后赶超期日本通过"温和"的金融约束实现了金融深化,但金融约束政策在应该放松甚至退出的时机没有放松或退出阻碍了金融体系促进经济增长的作用;金融自由化以来日本通过市场增进--体系重建与改进监管并进的路径实现了金融深化.日本的经验证明金融部门的深化可以促进经济发展,但其效果视不同经济体的发展阶段而不同,不同经济体应视各自经济体的情况选择金融深化的手段.日本金融深化过程中金融制度"创新"与"监管"并举的做法对后危机时代各国金融体系的重建具有重要的借鉴意义.
