This study examines both the quantity and price of risk exposure for different segments of financial intermediaries. Overall, we find evidence of market segmentation in the U.S. financial services industry. Specifically, we find that securities firms, consistently over the sampling period 1974–1994, had the most market risk exposure with the lowest market risk premium. Banks' market risk fluctuated over the sampling period. Banks increased their market risk-taking after the shift in monetary target in October 1979 and the announcement of the risk-based capital requirements in July 1988. The banks' market risk became the highest and insignificantly different from securities firms'. The results are consistent with the moral hazard argument; that is, banks took on more risk to take advantage of government guarantees as their charter value declined. Banks were subject to relatively high interest rate risk premium. However, in response to increased interest rate volatility and decreased charter value after October 1979, banks (while they increased their market risk exposure) lowered their interest rate risk exposure to an insignificant level. The results suggest that the federal safety net may have been perceived by the market as covering only market risk but not interest rate risk. Overall, we find little evidence of interest rate risk exposure, suggesting the prevalence of hedging programs using interest rate derivatives. The interest rate risk premiums, unlike the risk exposure, differ across financial intermediaries.  相似文献

Credit risk transfer and contagion   总被引:3,自引:0,他引:3  
Some have argued that recent increases in credit risk transfer are desirable because they improve the diversification of risk. Others have suggested that they may be undesirable if they increase the risk of financial crises. Using a model with banking and insurance sectors, we show that credit risk transfer can be beneficial when banks face uniform demand for liquidity. However, when they face idiosyncratic liquidity risk and hedge this risk in an interbank market, credit risk transfer can be detrimental to welfare. It can lead to contagion between the two sectors and increase the risk of crises.  相似文献

The loan market is a hybrid between a public and a private market, comprised of financial institutions with access to private information about borrowing firms. We test whether this is reflected in informationally efficient price formation in the loan market vis-a-vis the equity markets, and reject this private information hypothesis. We also reject a liquidity hypothesis which suggests that equity markets always lead loan markets, despite bank lenders' access to private information, because of greater liquidity in equity markets. We further test, and reject, an asymmetric price reaction hypothesis that states that loan returns are more sensitive to negative information whereas equity returns respond symmetrically to both positive and negative information. We find evidence most consistent with an integrated markets hypothesis that suggests that both the equity and syndicated bank loan markets are highly integrated such that information flows freely across markets. This is particularly true when the equity market makers are also loan syndicate members.   相似文献

Abstract

Metabolic syndrome and its association with mortality have not been studied in insured lives populations. The Swiss Re Study evaluated metabolic syndrome prevalence and associated mortality from all causes and circulatory disease in a cohort of 35,470 predominantly healthy individuals, aged 18–83 years, who were issued life insurance policies between 1986 and 1997. Metabolic syndrome was defined using the National Cholesterol Education Program (NCEP) Expert Panel Adult Treatment Panel (ATP) III guidelines. The NCEP obesity criteria were modified with a prediction equation using body mass index, gender, and age substituted for waist circumference. Adjustments also were made for nonfasting triglyceride and blood glucose values. Risk ratios for policyholders identified with metabolic syndrome were 1.16 (P = .156) for mortality from all causes and 1.45 (P = .080) for mortality from circulatory disease compared with individuals without the syndrome. Risk was proportional to the number of components, or score, of the metabolic syndrome present. Risk ratios for metabolic syndrome score were 1.14 (P < .001) for mortality from all causes and 1.38 (P < .001) for mortality from circulatory disease compared with individuals without metabolic syndrome factors. In both all-cause and circulatory death models, relative risk was highest for the blood pressure risk factor. Based on a modified NCEP definition, increased mortality risk is associated with metabolic syndrome in an insured lives cohort and has life insurance mortality pricing implications.  相似文献

Prior literature suggests that the market underreacts to the positive correlation in a typical firm's seasonal earnings changes, which leads to a post‐earnings‐announcement drift (PEAD) in prices. We examine the market reaction for a distinct set of firms whose seasonal earnings changes are uncorrelated and show that the market incorrectly assumes that the earnings changes of these firms are positively correlated. We also document that positive (negative) seasonal earnings changes in the current quarter are associated with negative (positive) abnormal returns in the next quarter. Thus, we observe a reversal of abnormal returns, consistent with a systematic overreaction to earnings, rather than the previously documented PEAD. Additional analysis indicates that financial analysts similarly overestimate the autocorrelation of these firms, although to a lesser extent. We also find that the magnitude of overestimation and the subsequent price reversal are inversely related to the richness of the information environment. Our results challenge the notion that investors recognize but consistently underestimate earnings correlation and provide a new perspective on the inability of prices to fully reflect the implications of current earnings for future earnings. That is, we show that investors predictably overestimate correlation when it is lacking, but underestimate it when it is present.  相似文献

While technology and health care delivery are inextricably and increasingly intertwined and technology has driven major advances in quality and efficiency in health care, technology does not replace the need for a thinking human being in care delivery. The term "technicity" refers to the tension created by the ability of humans to think versus their risk of being exploited as objects subservient to technologies. Drawing upon the philosophical works of Thoreau, Heidegger, and others, the authors pause on the conundrum created by expanding technology with the assumption that technological "improvements" should be evaluated with caution. Health care information systems are an example of tools that have improved our ability to collect and store information, but when systems "go down," staff can be rendered helpless. Similarly, technology can impose personal distance between the patient and provider in instances where staff are positioned as a mechanism for collecting data rather than a person interacting with another person. In some cases, health care providers function as navigators helping patients reach the correct pharmaceutical, rather than as teachers helping patients seek better health. Lastly, the tendency toward systems analysis in the context of the complex hospital environment leads solely toward uniform solutions rather than instances where a customized solution is warranted.  相似文献

We examine the effect of a federally-funded local infrastructure spending program on local unemployment rates. To address the likely funding endogeneity problem, we exploit variation in spending due to pork-barreling, and find that higher government expenditure on roads substantially reduces local unemployment.  相似文献

Public disclosure programs that collect and disseminate information about firms’ environmental performance are increasingly popular in both developed and developing countries. Yet little is known about whether they actually improve environmental performance, particularly in the latter setting. We use detailed plant-level survey data to evaluate the impact of India’s Green Rating Project (GRP) on the environmental performance of the country’s largest pulp and paper plants. We find that the GRP drove significant reductions in pollution loadings among dirty plants but not among cleaner ones. This result comports with statistical and anecdotal evaluations of similar disclosure programs. We also find that plants located in wealthier communities were more responsive to GRP ratings, as were single-plant firms.  相似文献
