We find that credit risk indicators price equally in the long run for the first part of the sample, while the linkage is less robust for the second. Moreover we show that the estimated no-arbitrage relations differ from those suggested by the theory, reflecting other elements than credit risk into prices. In the short run, the dynamic relation suggest a two-way linkage among different markets for credit risk. Results from long term dynamic analysis suggest that both CDS and ASWPS contribute equally to price discovery, while OAS market moves ahead of the derivative market for the pre-Lehman period, especially for European firms. On the other hand, CDS market is the main forum for credit risk after Lehman bailout, irrespective of geographical areas.","PeriodicalId":11800,"journal":{"name":"ERN: Stock Market Risk (Topic)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81006370","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper investigates the weak form efficiency of the Colombo Stock Ex-change by analyzing returns on the two key indices of the exchange which are the All Share Price Index and the Milanka Price Index over a long term period commencing from the year 1985 up to the year 2009. Weak form efficiency is tested subjecting both the indices using returns both on a daily as well as a monthly basis testing the random walk hypothesis using four techniques of Autocorrelation and the use of a non-parametric test which is the runs test. Results of these tests prove that based on the daily returns that the market is weak form inefficient. When considering the monthly returns the runs test states that the market is efficient while Q statistic gives mixed results. The other tests are in line with the daily returns. The paper also considers anomalous behaviour in the Colombo Stock Exchange, with the intention of possibly identifying a day-of-the-week effect or a month-of-the-year-effect.","PeriodicalId":11800,"journal":{"name":"ERN: Stock Market Risk (Topic)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73397982","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In accordance with the regulatory guidelines, Daniel Kaltofen, Stephan Paul and Stefan Stein develop an ‘optimised segmentation approach’ with regard to the credit default event and measure the implications for regulatory capital requirements. As regards methodology, they present an innovative technique and test it on a data set of approximately 413,000 motor vehicle loans. By classifying loans according to selective predictors of default, the authors find that banks can achieve significant savings in terms of ensuring a lower regulatory capital requirement. This provides banks with the opportunity to increase lending capacity. The technique overcomes the disadvantages of the more familiar standard methods used in today’s bank risk management and delivers more robust results.","PeriodicalId":11800,"journal":{"name":"ERN: Stock Market Risk (Topic)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2006-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85297650","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In contrast with CAPM, realized variance by itself provides negligible information about future excess stock market returns; however, we uncover a positive and significant risk-return tradeoff in many countries after controlling for the (U.S.) consumption-wealth ratio. U.S. realized variance is also significantly related to future international stock market returns; more importantly, it always subsumes the information content of its local counterparts. Our results indicate that stock market variance is an important determinant of the equity premium.","PeriodicalId":11800,"journal":{"name":"ERN: Stock Market Risk (Topic)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2006-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76143981","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It makes contribution in three separate areas of production economics. First, we model producers' attitude toward risk and derive risk preference functions (without assuming any parametric form of the utility function and any distribution of the error term representing production risk) when risk arises from production uncertainty and technical inefficiency. Second, the standard production risk model is extended to accommodate technical inefficiency and producers' attitude toward risk. Finally, the technical efficiency model is generalized to accommodate production risk and producers' attitude toward risk.

Since prior studies find Standard & Poor's common stock rankings provide investors with a measure of risk, a ranking change may signify a change in risk. Common stock ranking changes made by Standard & Poor's may provide investors with a low-cost means of predicting the direction of future market risk. Internal memoranda containing ranking changes from June 1985 through May 1987 were obtained directly from Standard & Poor's. Using a sample of 191 upgrades and 582 downgrades, results indicate that mean portfolio betas change following Standard & Poor's memorandum dates for ranking changes.","PeriodicalId":11800,"journal":{"name":"ERN: Stock Market Risk (Topic)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1991-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87349328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
