We examine whether the information in cap and swaption prices is consistent with realized movements of the interest rate term structure. To extract an option-implied interest rate covariance matrix from cap and swaption prices, we use Libor market models as a modelling framework. We propose a flexible parameterization of the interest rate covariance matrix, which cannot be generated by standard low-factor term structure models. The empirical analysis, based on US data from 1995 to 1999, shows that option prices imply an interest rate covariance matrix that is significantly different from the covariance matrix estimated from interest rate data. If one uses the latter covariance matrix to price caps and swaptions, one significantly underprices these options. We discuss and analyze several explanations for our findings.  相似文献

This paper introduces measures of volatility and jump risk that are based on individual stock options to explain credit spreads on corporate bonds. Implied volatilities of individual options are shown to contain useful information for credit spreads and improve on historical volatilities when explaining the cross-sectional and time-series variation in a panel of corporate bond spreads. Both the level of individual implied volatilities and (to a lesser extent) the implied-volatility skew matter for credit spreads. Detailed principal component analysis shows that a large part of the time-series variation in credit spreads can be explained in this way.  相似文献

This article reports results from a framed market experiment conducted to examine whether milk choices are responsive to changes in the nutritional characteristics of milk products. Using a random‐effect Tobit model, we analyzed experimental data collected from 160 participants in urban Ethiopia. It shows that sensory properties play a key role in the acceptance of reduced‐fat milk while the provision of nutrition information has a mixed effect on a price premium. Further, a substantial percentage of participants were found to have a strong preference for whole milk while only 19% of them prefer reduced‐fat milk with 2.8% price premium. The study unveils a heterogeneous preference for the nutritional quality of milk products. Consumers’ health problems and socio‐demographic characteristics influence their preference for the nutritional quality of milk products. The result also shows a nutrition‐taste tradeoff, yet consumers place more value on sensory experience. Contrary to earlier studies, we found that prior belief about milk quality influences how consumers value sensory experience and nutrition information.  相似文献

Measuring Producers' Risk Preferences: A Global Risk-Attitude Construct   总被引:1,自引:0,他引:1  
In applied agricultural economic research various risk-attitude elicitation techniques are used. Here, we investigate whether risk-attitude measures rooted in the expected utility framework are related to measures rooted in the multi-item scale framework. Using a second-order factor analytical model, and data obtained from personal computer-guided interviews with 373 farmers, we investigate whether the common variance among the (latent) risk-attitude measures can be accounted for by a global risk-attitude construct. We find that the different risk-attitude measures are related, and that the global risk-attitude construct is significantly related to farmers' intention to use futures contracts. Our research suggests that farmers' risk attitude is a higher-order characteristic that cannot be effectively extracted by a single measure.  相似文献

Processes of politicization and depoliticization are increasingly studied in relation to urban contexts, and cities have been depicted as incubators of social movements. What has been largely ignored is why, in some cities, forces of politicization or depoliticization are stronger than in others. To address this question, this article compares two British cities—Manchester and Bristol—which have historically been central hubs of environmental resistance, but currently face similar depoliticizing forces: austerity, anti-squatting laws, police repression and activists’ disillusion with environmentalism. Curiously, these conditions have had very different impacts on the two environmental scenes. In Manchester they have caused environmental resistance to become replaced almost entirely by non-confrontational ‘alternatives’. In Bristol alternatives have emerged that tend to be in synergy with environmental resistance. The comparison thus suggests that Bristol is more conducive to maintaining environmental resistance under depoliticizing conditions. Findings suggest that differences can be attributed to features of the physical urban environment, including city size. Historically, these differences were not decisive. Yet, after a period of dwindling environmentalist energy in the UK, the number of environmentalist hubs has been reduced. This has prompted a reputational snowball that increasingly concentrates environmental resistance in the one city that best insulates the environmental movement from broader depoliticizing forces.  相似文献

We study the relative and absolute pricing of CMBX contracts (commercial real estate derivatives) during the recent financial crisis. Using a structural CMBX pricing model, we find little systematic mispricing relative to REIT equity and options. We do find short-term deviations from this relative pricing relationship that are statistically and economically significant. In particular, the CMBX market temporarily overreacts to news announcements. We provide evidence that this temporary mispricing is caused by price pressure due to hedging activities. Finally, an absolute pricing analysis provides no substantial evidence that CMBX contracts traded at fire sale levels during the crisis.  相似文献

We investigate earnings announcement lags (period from the end of the reporting period until the announcement date) for the good and the bad quarterly earnings news across different market sentiment periods as well as market reactions thereto. Companies listed on Baltic stock exchanges exhibit clear signs of strategic timing of earnings announcements. Earnings announcement lags for the bad news tend to be longer than those for the good news. This difference is more pronounced during low market sentiment periods. If the release of the bad news is postponed, abnormal return responses remain lower, as expected.  相似文献

Research offers mixed evidence about the risk management decision‐making process of producers. Whether producers’ characteristics drive behavior directly or through risk attitude remains a puzzle. We assess whether managerial/firm characteristics directly affect choices or if their influence occurs indirectly through impacts on risk attitude. The findings, which support indirect effects, indicate that failure to represent relationships between risk attitude, other characteristics, and behavior appropriately can mask the effect of risk attitude. A more complete understanding of the structure of decision‐making may assist economists, policymakers, and industry stakeholders in designing and targeting mechanisms to manage or transfer risk.  相似文献

This paper develops an interdisciplinary conceptual framework demonstrating the role of marketing in managing investor relationships. The framework illustrates how companies can turn investor relationships into market-based assets by analyzing and managing them from a relationship marketing and stakeholder perspective. Marketing can contribute to investor relationship management and increase shareholder value by lowering the cost of equity capital, increasing analyst coverage and stock liquidity, and reducing shareholder activism. An investigation among investor relations professionals working at publicly traded companies in the Euronext 100 stock index demonstrates the framework's empirical validity and provides managerial implications.  相似文献

We empirically compare Libor and Swap Market Models for the pricing of interest rate derivatives, using panel data on prices of US caplets and swaptions. A Libor Market Model can directly be calibrated to observed prices of caplets, whereas a Swap Market Model is calibrated to a certain set of swaption prices. For both models we analyze how well they price caplets and swaptions that were not used for calibration. We show that the Libor Market Model in general leads to better prediction of derivative prices that were not used for calibration than the Swap Market Model. Also, we find that Market Models with a declining volatility function give much better pricing results than a specification with a constant volatility function. Finally, we find that models that are chosen to exactly match certain derivative prices are overfitted; more parsimonious models lead to better predictions for derivative prices that were not used for calibration.  相似文献
