Exchange rate exposure and foreign exchange derivatives: do ineffective hedgers modify future derivatives use?

Recent studies examining the relationship between stock returns and exchange rate changes have provided evidence that the exchange rate exposure of non-financial companies is reduced by the use of foreign exchange derivatives. Building on such research, this study investigates whether past ineffective derivative hedging contributes to explaining future derivatives use. To the extent that companies monitor the effectiveness of their currency risk management practices, past ineffective hedgers can be expected to modify their future use of foreign exchange derivatives accordingly. In our study of 94 non-financial US multinationals, we provide evidence that the change in derivatives use from 1996–1998 to 1998–2000 can be explained in part by the ineffective hedging of currency risk in 1996–1998, controlling for variables associated with theories of optimal hedging. Additional analyses confirm that such primary results are robust to firm size, the level of foreign operations, and the use of derivatives to partially hedge currency risk. Our results imply that as exchange markets and risk management practices change, the use of derivatives to manage exchange rate risk also changes. Our contribution to this field of study is that we find evidence that past ineffective hedgers tend to increase their future use of FXDs.     

The Cost of Capital of Cross‐listed Firms

This paper analyses the cost of capital of firms with foreign equity listings. Our purpose is to shed light on the question whether international and domestic asset pricing models yield a different estimate of the cost of capital for cross‐listed stocks. We distinguish between (i) the multifactor ICAPM of Solnik (1979) and Sercu (1980) including both the global market portfolio and exchange rate risk premia and (ii) the single factor domestic CAPM. We test for the significance of the cost of capital differential in a sample of 336 cross‐listed stocks from nine countries in the period 1980–99. Our hypothesis is that the cost of capital differential is substantial for firms with international listings, as these are often large multinationals with a strong international orientation. We find that the asset pricing models yield a significantly different estimate of the cost of capital for only 12% of the cross‐listed companies. The size of the cost of capital differential is around 50 basis points for the US, 80 basis points for the UK and 100 basis points for France.     

对我国上市银行非经常性损益披露的分析和建议

本文通过分析2001至2004年上市银行年报非经常性损益的披露状况,对照监管部门法规,发现存在披露不充分的现象,对非经常性损益的确认也有理解偏颇,由此造成很多重大的可疑事项未计入非经常性损益。本文认为这对银行利润的真实性产生一定的影响,故建议政策制定者制定更详细的法规来规范披露行为,并就一些特殊事项做出释疑。     

Progressive stress accelerated life tests under finite mixture models

In this paper, progressive stress accelerated life tests are considered when the lifetime of a product under use condition follows a finite mixture of distributions. The experiment is performed when each of the components in the mixture follows a general class of distributions which includes, among others, the Weibull, compound Weibull, power function, Gompertz and compound Gompertz distributions. It is assumed that the scale parameter of each component satisfies the inverse power low, the progressive stress is directly proportional to time and the cumulative exposure model for the effect of changing stress holds. Based on type-I censoring, the maximum likelihood estimates (MLEs) of the parameters under consideration are obtained. A special attention is paid to a mixture of two Rayleigh components. Simulation results are carried out to study the precision of the MLEs and to obtain confidence intervals for the parameters involved.     

转型期国有企业改革的伦理困惑与破解--基于中国的实践和西方的经验

经济转型意味着旧的"社会契约"被打破,而新的契约尚未订立,作为企业行为调控机制的伦理作用得以彰显.我们在分析市场经济体制下,西方企业在不同管理时代的"伦理"与"绩效"关系的基础上,阐明企业伦理本身的特有属性及经营绩效的内涵;同时结合中国国有企业目前面临的伦理困惑,认为国有企业要破解这些伦理困惑,就必须根据变化了的现实对其管理伦理进行合理定位,以"社会期望"为前提谋求企业与社会的和谐,以市场经济游戏规则为准谋求企业之间的和谐,以人本管理为依托达到企业与员工关系的和谐统一、以生态优先为基准谋求企业与自然的伙伴关系,以与全球经济接轨为基础实现国有企业组织个性化,以"权威声誉、伦理声誉"营造社会激励伦理行为的氛围.     

金融租赁公司的利率风险及管理对策

金融租赁公司所面临的诸多利率风险中,成熟期错配风险是最为关键的,久期模型是其通用的衡量方法。金融租赁公司的久期缺口分析是利用久期管理利率风险的主要方法,但久期模型运用中也存在着诸如久期对称成本高、利率风险免疫动态性及凸性等问题。金融租赁公司面对利率上升的风险,应采取设立风险管理部门、做好基础资料积累与分析、加强利率走势预测及对金融衍生工具的研究等对策措施。     

Banks’ non-traditional activities under regulatory changes: impact on risk,performance and capital adequacy

Using the big six Canadian chartered banks quarterly financial statements and daily stock market data from 1982 to 2018, we examine the impact of non-interest income on Canadian banks’ risk, performance and capital under the different major regulatory changes made to the Bank Act of Canada. Our results show that Canadian banks’ expansion into non-traditional activities had slightly decreased their risks and significantly improved their performance benefitting from income diversification. Moreover, while adhering to capital adequacy regulation, reshuffling banks’ portfolio towards non-traditional activities did not reduce Canadian banks’ capital ratio. In spite of the re-regulation towards universal banking against ring-fencing, this feature buttresses the effectiveness of capital adequacy regulation in Canada in linking banks capital allocation with their risk taking.

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。     

Monetary Policy,Trend Inflation,and Unemployment Volatility

The literature has long agreed that the DMP model (after Diamond 1982, Mortensen 1982, Pissarides 1985) with search and matching frictions in the labor market can deliver large volatilities in labor market quantities, consistent with empirical data, only if there is at least some wage stickiness. I show, however, that the model can deliver nontrivial volatilities without wage stickiness, as long as it has price dispersion and nonzero long‐run inflation rates. I find that by keeping inflation at a positive rate, monetary policy may be accountable for the large standard deviations observed on labor market variables. In addition, the Shimer (2005) puzzle disappears under monetary policy shocks.
