Market Failures in Real-Time Metering

Policies to promote real-time metering (RTM) require more than showing benefits from more timely responses to variations in cost. They require positive externalities to imply that too few meters would be installed through private transactions. RTM presents no systematic externalities when utilities must serve peak period users, and may present negative externalities under some conditions. Positive externalities are likely when electricity is rationed through blackouts. RTM may or may not increase welfare when peak period wholesale markets are not competitive; a prohibition on RTM might be appropriate in such situations even if metering itself were costless.     

信贷配给、内生金融约束与中小企业融资

中小企业的迅速崛起,对中国经济产生了不可估量的贡献,但是中小企业在取得巨大发展的同时却面临着融资难的困境,本文试图用“二元经济”模式下的“二重信贷配给”来解释中小企业融资困境,并提出中小企业解决融资困境的路径,即利率市场化、信贷联网体系和信贷担保体系。

中小企业融资困境的经济学解释

中小企业的迅速发展,使我国在整体经济不利的环境下保持了较快的增长速度。但是中小企业在取得巨大发展的同时,在信贷市场上却面临着商业银行的信贷配给,陷入融资难的困境。文章试图从信贷配给的视角解释商业银行面对中小企业的信贷配给,用二元经济模式下的双重信贷配给解释中小企业的融资困境,并且提出中小企业解决融资困境的一条可行性途径,即市场利率化,信贷信息联网以及信贷担保体系。

Models of Capital Investments with Private Information and Incentives: a Selective Review

The purpose of this paper is to selectively review research that addresses capital budgeting decisions in settings characterized by dispersed information and incentive problems. The papers are theoretical; they formulate and analyze models that vary in the number of periods considered, the number of economic actors involved, and the number of alternative projects available. The aims of the review are to describe some of the formulations that have been studied, to highlight their key economic and mathematical properties, to reveal their common economic forces, and to collect and organize their basic results.     

货币政策效果非对称性及"阀值效应"分析

本文基于1992年1季度至2005年2季度数据，运用LM检验和t检验，研究我国货币政策的非对称性以及“阀值效应”，得出我国货币政策的“阀值”在-0．08-0．05之间。货币政策的非对称性和“阀值”的存在是由于微观信贷市场上的信贷配给导致的。“阀值”和“阀值效应”的存在反映了信贷配给的强弱程度，“阀值”可以用作度量信贷配给程度的指标，它间接地反映了信贷市场的完善程度。     

论股权配给作用于宏观经济波动的机理

当宏观经济进入衰退阶段时,由于融资企业的股权配给,融资企业投资的边际破产成本上升,这将导致融资企业的投资下降,在投资乘数原理和加速数原理的相互作用下,会使宏观经济衰退更加严重,宏观经济陷入经济衰退与股权配给相互作用的恶性循环中,宏观经济衰退的程度会进一步加大。当宏观经济进入繁荣阶段时,具有与上述相类似的过程,会导致宏观经济持续过度繁荣。因此,股权配给是宏观经济波动的加速器。我国的现实是,从微观上看,上市公司具有强烈的股权融资偏好;从宏观上看,政府进行股权配给。两者的共同作用,使股权配给具有平抑宏观经济波动的功能。     

ON THE PROFITABILITY OF RESALE PRICE MAINTENANCE WHEN DEMAND IS UNCERTAIN

A previous study finds that in a market where a manufacturer faces uncertain demand and sells to consumers through competitive retailers, the manufacture wishes to support adequate retail inventories by imposing resale price maintenance (RPM). I show that if retail inventories are allocated to consumers through first‐come‐first‐served rule rather than efficient rationing rule in the game with unconstrained retail competition, imposing RPM may not be profitable. It may not encourage more retail inventories either. RPM may also lower consumer surpluses and social welfare. This study casts some doubt on the demand uncertainty theory that supports RPM.
