Bank Capital and Risk: Is Voluntary Disclosure Enough?

This paper considers whether banks have an incentive to disclose accurate information concerning their risk and capital adequacy. State-of-the-art capital regulation relies on quantitative capital requirements, bank supervision, and public disclosure of information to the markets. Is voluntary regulatory disclosure of risk information sufficient to achieve policy objectives? The game-theoretic model of this paper suggests that voluntary disclosure can be usefully supplemented with other regulatory tools, in particular with direct supervision and financial market discipline.     

Modeling coordinated foreign exchange market interventions: The case of the Japanese and U.S. interventions in the 1990s

During the past thirty years, central banks often intervened in foreign exchange markets. Sometimes they carried out foreign exchange market interventions on a unilateral basis. However, central banks often coordinated their foreign exchange market interventions. We develop a quantitative reaction function model that renders it possible to study the factors that made central banks switch from unilateral to coordinated interventions. We apply our model to the intervention policies of the Japanese monetary authorities and the U.S. Federal Reserve in the yen/U.S. dollar market during the period 1991–2001. To this end, we use recently released official data on the foreign exchange market interventions of the Japanese monetary authorities. JEL no. F31, F33, G14, G15     

ECB Foreign Exchange Intervention and the EURO: Institutional Framework,News, and Intervention

Using a unique intervention news data set, this paper investigates the impact of ECB intervention and intervention-related news (newswire reports) on the Euro exchange rate. A time-series study of news generated by ECB officials and market participants regarding intervention and the value of the Euro as well as an event study of firm reports of ECB intervention is conducted. Both studies find significant short-run effects on the Euro value, while only negative statements (official statements denying past intervention or ruling out future intervention) appear to have persistent effects.

Sub-debt Yield Spreads as Bank Risk Measures

Several recent studies have recommended greater reliance on subordinated debt as a tool to discipline bank risk taking. Some of these proposals recommend using sub-debt yield spreads as triggers for supervisory discipline under prompt corrective action (PCA). Currently such action is prompted by capital adequacy measures. This paper provides the first empirical analysis of the relative accuracy of various capital ratios and sub-debt spreads in predicting bank condition: measured as subsequent CAMEL or BOPEC ratings. The results suggest that some of the capital ratios, including the summary measure used to trigger PCA, have almost no predictive power. Sub-debt yield spreads performed slightly better than the best capital measure, the Tier-1 leverage ratio, albeit the difference is not significant. The performance of sub-debt yields satisfies an important pre-requisite for using sub-debt as a PCA trigger. However, the prediction errors are relatively high and further work to refine the measures would be desirable.     

Technical analysis and central bank intervention

This paper extends genetic programming techniques to show that US foreign exchange intervention information improves technical trading rules' profitability for two of four exchange rates over part of the out-of-sample period. Rules trade contrary to intervention and are unusually profitable on days prior to intervention, indicating that intervention is intended to halt predictable trends. Intervention seems to be more successful in checking such trends in the out-of-sample (1981–98) period than in the in-sample (1975–80) period. Any improvement in performance results from more precise estimation of the relationship between current and past exchange rates, rather than from information about contemporaneous intervention.     

责任会计在商业银行中的应用研究

本文认为,我国商业银行应推行责任会计,将商业银行内部划分为若干责任中心,把商业银行制定的预算、目标和任务按部门进行分解,形成各责任中心的预算、目标和任务,通过分部门核算的方式对各责任中心的目标预算执行情况进行控制,并对执行结果进行考核。使会计活动从记录、反映和监督商业银行的财务活动向为商业银行管理服务拓展,充分发挥预算、控制、考核、分析和经营决策的作用,从而保证商业银行经营管理目标的实现。
