基于IC卡的密钥管理系统

安全性是银行对交易媒介的基本要求,它包括两个方面:系统的安全性、金融交易数据的安全性。银行要求在金融交易发生和处理的整个过程中保障关键和重要数据的安全。IC 卡作为新涌现出的一种金融卡,除了要满足金融卡的基本安全要求外,还有一些具有卡的脱机交易以及卡上数据保护的安全要求。为了保证 IC 卡在金融业的应用向广度和深度方向发展,确保 IC 卡各种交易的安全性与可靠性,维护银行的信誉,有必要在 IC 卡应用中制定一套完整的、全面的安全体系。本文参照人行的 IC 卡规范并结合建设银行在 IC 卡应用与安全上的具体要求,提

中东欧转轨国家外资持股比例与银行竞争力、金融安全关系的实证考察

近年来我国银行业引进境外战略投资者的行为引发了理论界关于外资持股比例对中资银行竞争力提升与国家金融安全影响的争论。本文选取与我国具有相似的银行业改革历程、但改革先于我国的中东欧转轨国家为样本,实证考察这些国家外资持股比例与银行竞争力提升和金融安全之间的关系。得出的基本结论是:外资持股比例与银行竞争力的提升具有一定的联系,但并不十分紧密;从金融与经济关系的视角考察外资持股比例与金融安全的关系,并不能得出外资持股比例越高的银行对金融安全的威胁性越大的结论。     

Litigating crashes? Insights from security class actions

Investors tend to litigate large stock price declines, i.e., file ‘stock-drop lawsuits’. However, it is less clear whether the ex-ante threat of security class actions can deter stock price crashes in the first place. To answer this question, we exploit the 1999 ruling of the Ninth Circuit Court of Appeals that discourages security class actions as a quasi-exogenous shock, and find that reducing the threat of security class actions leads to a significant increase in stock price crash risk measured by negative skewness of stock returns. We reveal that the main effect is partially driven by a reduction in the timeliness of bad news disclosure and worsened earnings quality, which is consistent with the view that bad news hoarding serves as the key factor in the formation of a stock price crash. Our overall findings highlight the importance of security class actions in deterring the occurrence of firm-level negative tail events on the financial market.     

Pricing European Options by Numerical Replication: Quadratic Programming with Constraints

The paper considers a regression approach to pricing European options in an incomplete market. The algorithm replicates an option by a portfolio consisting of the underlying security and a risk-free bond. We apply linear regression framework and quadratic programming with linear constraints (input = sample paths of underlying security; output = table of option prices as a function of time and price of the underlying security). We populate the model with historical prices of the underlying security (possibly massaged to the present volatility) or with Monte Carlo simulated prices. Risk neutral processes or probabilities are not needed in this framework.     

Asymmetric information and imperfect competition in a continuous time multivariate security model

This paper deals with the problem of price formation in a market with asymmetric information and several risky assets. We then extend the multivariate security model of Caballé and Krishnan (1994) to a continuous time framework, and general utility function. Our model enables us to observe some results which are specific to multi security markets such as Giffen effect. An application of the main result will be the non trivial generalizations of the models of Back (1992) and Cho (1997).Mathematics Subject Classification (1991): 49L10, 60G44, 90A15JEL Classification: G11, G12The author would like to thank his supervisor H.

Anticipated foreign military threat, arms accumulation, and the current account in a small open economy

This paper examines the effects of an anticipated foreign military threat on consumption, the home weapons stock, and net foreign asset position in a small open economy. If the utility function is separable between butter and guns, the economy decreases both butter and guns when the news arrives, accumulates foreign assets prior to the foreign threat realization, and increases guns as the foreign threat realizes. If the utility function is nonseparable between butter and guns, the economy may have two dynamic responses. The first is similar to the separable case, except that consumption exhibits a discrete jump when the foreign threat realizes. The second is that the economy increases both butter and guns on impact, decumulates foreign assets prior to the foreign threat implementation, but either increases or decreases guns as the foreign threat realizes.     

Asset allocation and liquidity breakdowns: what if your broker does not answer the phone?

This paper analyzes the portfolio decision of an investor facing the threat of illiquidity. In a continuous-time setting, the efficiency loss due to illiquidity is addressed and quantified. For a logarithmic investor, we solve the portfolio problem explicitly. We show that the efficiency loss for a logarithmic investor with 30 years until the investment horizon is a significant 22.7% of current wealth if the illiquidity part of the model is calibrated to the Japanese data of the aftermath of WWII. For general utility functions, an explicit solution does not seem to be available. However, under a mild growth condition on the utility function, we show that the value function of a model in which only finitely many liquidity breakdowns can occur converges uniformly to the value function of a model with infinitely many breakdowns if the number of possible breakdowns goes to infinity. Furthermore, we show how the optimal security demands of the model with finitely many breakdowns can be used to approximate the solution of the model with infinitely many breakdowns. These results are illustrated for an investor with a power utility function.
