High-temperature exposure risk,corporate performance and pricing efficiency of the stock market

Using the daily temperature data of the national meteorological stations, we measure the high-temperature exposure risk of Chinese A-share listed enterprises, investigate the impact of high-temperature exposure risk on corporate prime operating revenue and performance, and further discuss securities analysts' forecasts for this risk. We find that increased exposure to high temperature reduces corporate prime operating revenue, and the response of enterprises to high-temperature risk will lead to a rise in management expenses and the deterioration of business performance. Further evidence suggests that securities analysts generally underestimate or ignore the impact of high-temperature exposure risk, and our results are robust to different measures and samples.

Stochastic durations,the convexity effect,and the impact of interest rate changes

This article shows that the equilibrium models of bond pricing do not preclude arbitrage opportunities caused by convexity. Consequently, stochastic durations derived from these models are limited in their ability to act as interest rate risk measures. The research of the present article makes use of an intertemporal utility maximization framework to determine the conditions under which duration is an adequate interest rate risk measure. Additionally, we show that zero coupon bonds satisfy those equilibrium conditions, whereas coupon bonds or bond portfolios do not as a result of the convexity effect. The results are supported by empirical evidence, which confirms the influence of convexity on the deviation of coupon bond returns from equilibrium.     

Risk‐Adjusted Measures of Value Creation in Financial Institutions

Abstract Many financial institutions assess portfolio decisions using RAROC, the ratio of expected return to risk (or ‘economic’) capital. We use asset pricing theory to determine the appropriate hurdle rate, finding that this varies with the skewness of asset returns. We quantify this discrepancy under a range of assumptions showing that the RAROC hurdle rate differs substantially, being higher by a factor of five or more for equity which has a right skew compared to debt which has a pronounced left skew, and also between different qualities of debt exposure. We discuss implications for both financial institution risk management and supervision.
