Interventions in Markets with Adverse Selection: Implications for Discount Window Stigma

I study the implications for central bank discount window stigma of a workhorse model of adverse selection in financial markets. In the model, firms (banks) need to borrow to finance a productive project. There is limited liability and firms have private information about their ability to repay their debts, which gives rise to the possibility of adverse selection. The central bank can ameliorate the impact of adverse selection by lending to firms. Discount window borrowing is observable and it may be taken as a signal of firms' credit worthiness. Under some conditions, firms borrowing from the discount window may pay higher interest rates to borrow in the market, a phenomenon often associated with the presence of stigma. I discuss these and other outcomes in detail and what they suggest about the relevance of stigma as an empirical phenomenon.     

Competitive effects of Basel II on US bank credit card lending

We analyze the potential competitive effects of the proposed Basel II capital regulations on US bank credit card lending. We find that bank issuers operating under Basel II will face higher regulatory capital minimums than Basel I banks, with differences due to the way the two regulations treat reserves and gain-on-sale of securitized assets. During periods of normal economic conditions, this is not likely to have a competitive effect; however, during periods of substantial stress in credit card portfolios, Basel II banks could face a significant competitive disadvantage relative to Basel I banks and nonbank issuers.     

Initial Margin Requirements, Volatility, and the Individual Investor: Insights from Japan

Initial margin requirements represent: (1) a cost impediment to the wealth constrained investor and (2) a potential way of mitigating excessive volatility. However, prior empirical research finds that margins are not an effective tool in reducing volatility. We consider the possibility that margins primarily affect certain stocks and investors. Specifically, we test whether margins affect individuals who, as a group, we believe to be the investors most affected when margin requirements change. Our initial empirical tests, however, do not support this contention.     

油(气)田储量技术经济综合评价理论与方法研究

本文从界定油(气)田(藏)储量技术经济综合评价的概念入手,阐述了综合评价的必要性和当前存在的问题;分析了油(气)勘探开发的特点,明确了综合评价在技术经济评价中的重要作用;针对综合评价要求实现定量评价指标与定性描述的有机结合,文章列举了当前综合评价普遍存在的问题为:指标选取不全面、指标权重的确定不够客观,从而形成综合评价的结果的简单无力,不足以作为决策的有力依据等;据此,文章提出构造综合评价指标体系,用层次分析法(AHP 法)确定指标权重的方法.再者,由于油(气)开发决策是模糊决策,因而本文运用模糊集合理论建立油(气)田(藏)储量技术经济综合评价的多层次、多算子二型模糊数学综合评价模型,并通过实例证明该方法的计算方便可靠,符合客观实际。     

发展中国家外汇储备激增的原因和对策

发展中国家外汇储备激增,其规模大大超过了一般要求水准。发展中国家储备激增的原因在于经济发展、危机预防需求增长和外汇管理政策的变动。发展中国家储备激增对本国经济和世界经济产生了多方面的影响。防范外汇储备激增带来的风险可采取改善汇率和外汇管理政策,增加外债偿付以及利用储备对国内金融机构重资本化等方式。

Voting requirements, concessions, international side payments and the European Monetary Union

This paper addresses the question of criteria for selection of EMU members. We identify two factors in the decision process: (1) The costs and benefits which the individual countries attribute to alternative EMU arrangements (`hard-core', medium-sized, all EU members), and (2) the binding institutional restrictions, i.e., the distribution of votes in the European Council and the minimum vote requirements. Within this framework the EU countries are assigned to different groups according to their degree of convergence. Based on stability concessions and side payments these groups decide on the final EMU composition. We show that minimum vote requirements can lead to a suboptimal size of the EMU and can threaten the feasibility of a multi-speed monetary union.

浅议我国最佳外汇储备规模

截止到2005年12月底，我国的外汇储备已达到8000亿美元，关于其数额是多是少的争论进行得如火如荼。本文对充足外汇储备给我国经济和社会带来的有利之处进行了理论上的分析后．又采取数学方法对我国2004年最佳的外汇储备数额进行了测算．得出了一个结论：我国的外汇储备并不多。然后，在此基础上对我国外汇储备的管理提出了几点建议。
