Quantile forecasts of daily exchange rate returns from forecasts of realized volatility 总被引:2,自引:0,他引:2
Quantile forecasts are central to risk management decisions because of the widespread use of Value-at-Risk. A quantile forecast is the product of two factors: the model used to forecast volatility, and the method of computing quantiles from the volatility forecasts. In this paper we calculate and evaluate quantile forecasts of the daily exchange rate returns of five currencies. The forecasting models that have been used in recent analyses of the predictability of daily realized volatility permit a comparison of the predictive power of different measures of intraday variation and intraday returns in forecasting exchange rate variability. The methods of computing quantile forecasts include making distributional assumptions for future daily returns as well as using the empirical distribution of predicted standardized returns with both rolling and recursive samples. Our main findings are that the Heterogenous Autoregressive model provides more accurate volatility and quantile forecasts for currencies which experience shifts in volatility, such as the Canadian dollar, and that the use of the empirical distribution to calculate quantiles can improve forecasts when there are shifts. 相似文献

The early prediction of bad debtors in revolving loans in Mexico is a relevant current issue. The proposed econometric model of behavioral scoring considers the changes in the characteristics of consolidated clients and produces better results than those obtained with methodology used by the CNBV on provisions. The obtained results show the possibility of replacing the current model, minimizing the expected loss and increasing the ROA of Mexican financial institutions in 2.20% complying the methodology and statistical testing criteria according to the Unique Banking Dispositions and the guidelines of Basel II on credit risk. 相似文献

We study the influence of market signals and agency problems on the decision to cancel an announced acquisition. We find major differences between deals involving private vs. public targets. First, controlling for the value of expected synergies, acquisitions are less likely to be cancelled when the target is private rather than public. This finding supports learning rather than the alternative common-information hypothesis. Second, better manager-shareholder interest alignment makes the cancellation of a “bad” deal more likely only when the target is a private firm. This suggests bidder agency problems have a greater influence on acquisition outcome (i.e., learning) when the target is private. Third, cancellation is more likely for private targets when their post-announcement abnormal returns are low, especially if the method of payment includes stock. This indicates that it is important to control for bidder overvaluation when testing the managerial learning hypothesis. Overall, both the learning and agency hypotheses help explain observed differences in deal completion by target type. 相似文献

Can Investors Identify Managerial Discretion in Corporate Social Responsibility Practices? The Moderate Role of Investor Protection 下载免费PDF全文
Jennifer Martínez‐Ferrero Óscar Villarón‐Peramato Isabel María García‐Sánchez 《Australian Accounting Review》2017,27(1):4-16
This paper analyses investors’ ability to identify if managers use corporate social responsibility as an entrenchment practice to conceal the risk of dismissal associated with managerial discretion and if this detection is determined by the level of investor protection orientation. Results based on an international database of 1949 companies show that investors and markets do not identify managerial entrenchment based on the promotion of sustainable practices, except when such entrenchment is developed by companies located in countries with strong investor protection. In these countries, investors identify and penalise such companies with lower financial performance. 相似文献

Until the outbreak of the recent economic and financial crisis, Spain was leading the ranking of countries with the largest share of temporary employees. During the crisis this share has fallen to its lowest level in decades, but this does not mean that working conditions in Spain have improved. The flow of new temporary contracts is larger than ever before. A particularly striking feature is the steep growth in the volume of fixed-duration contracts lasting less than a week or a month. We document these trends and analyse how this phenomenon has affected the transition from temporary to permanent employment. 相似文献

Construction prices are lower in developing countries in ICP 2005, which has raised these countries' capital/output ratio in Penn World Tables 7 and 8 and affected growth analyses. We estimate the Colombia/U.S. price ratio for office and apartment buildings in 2005 as a test of the validity of the ICP 2005 methodology for estimating these prices. Our estimate of the Colombia/U.S. price ratio is almost twice the ICP 2005 estimate. We confirm the validity of our results by estimating the cost of constructing office and apartment buildings using 2005 prices for construction materials, equipment, and labor in both countries. 相似文献

Since the 1990s, Argentinean dairy‐processing cooperatives have lost considerable amounts of members and market share. We analyse their current role by investigating the characteristics of farmers who continue delivering to them and price differentials between cooperatives and investor‐oriented firms (IOFs). A probit regression model applied to 917 farmers suggests that cooperative farmers are more disadvantaged than farmers delivering to IOFs in terms of education, farm size and productive technology. Moreover, t‐tests applied to data representing 70 per cent of national volume indicate that farmers delivering to cooperatives are between 11 per cent and 29 per cent smaller than those delivering to IOFs, depending on province. A hierarchical multilevel regression model applied to 9,720 transactions among farmers and processors shows that, after controlling for quantity and quality, cooperatives pay lower (3.5%) but more stable prices than IOFs. In a context of rapid structural change, we observe a market in which larger farmers deliver to IOFs and smaller farmers deliver to cooperatives and conclude that, at the expense of paying lower prices, cooperatives may act as buyers of last resort for otherwise disadvantaged farmers. 相似文献

The present study shows how the evaluation of sport motivation according to Achievement Goal Theory is different if the criteria
used are predominant goal orientation or motivational profile combination, as well as presenting its relationship with other
variables such as the amount of sport practise or the level of competition and success achieved. Seventy two men and women
participated, all students of Physical Educational and Sport Science, completing the Questionnaire on Motivational Orientation in Sport ((Guivernau and Duda, Revista de Psicología del Deporte, 5, 1994) a Spanish adaptation of the Task and Ego Orientation in Sport Questionnaire, TEOSQ, (Duda, J Sport Exerc Psychol, 11, 1989)). The results showed the existence of different motivational relationships
with variables of the practise of sport, depending on the type of profile used. Finally, the practical implications of these
findings are discussed with respect to the motivational climate generated in the teaching of Physical Education. 相似文献

This research focuses on examining the relationship between some attributes of assurance providers and the level of sustainability assurance. By using the propensity to issue negative conclusions in the assurance statement as an indicator of the level of assurance, we examine whether the brand name and industry specialisation of the practitioners have an impact on the assurance opinion issued. Using an international sample of 1233 firm-year observations over the period 2007–2014, the findings document the impact of the brand reputation and industry specialisation of assurance providers on the level of assurance. The probability of detecting material errors and omissions in a sustainability report is higher if it is verified by a Big 4 auditing firm and by an industry expert as an assurance practitioner. The greater experience in providing audit services and the relevant skills and training provided by Big 4 firms, as well as the greater knowledge and experience of industry experts, increase the propensity to report more accurate opinions about a sustainability report. The findings are robust for alternative measures for the level of assurance and the industry specialisation. 相似文献
