Default Risk in Equity Returns   总被引:17,自引:0,他引:17  
This is the first study that uses Merton's (1974) option pricing model to compute default measures for individual firms and assess the effect of default risk on equity returns. The size effect is a default effect, and this is also largely true for the book‐to‐market (BM) effect. Both exist only in segments of the market with high default risk. Default risk is systematic risk. The Fama–French (FF) factors SMB and HML contain some default‐related information, but this is not the main reason that the FF model can explain the cross section of equity returns.  相似文献

Foresight is rooted in deep understanding [A.N. Whitehead. Lecture notes from address to the Harvard Business School, 1931]. Such understanding requires that we shall have first looked back to the past before venturing forward into the future. This paper uses Weick’s and colleagues’ sense making perspective in order to explore this critical relationship between the past and the future [[2], [3], [4], [5], [6] and [7]]. In particular, key sense making properties will be applied to a crisis, an occurrence of school-place violence that occurred in the United States in 1999. We shall then ask how this organization and its diverse external stakeholders used their understanding of this event to learn how to prevent such crises from occurring in the future. In other words, how capably was hindsight constructed and then how was it used to strengthen foresight into the future? This paper will conduct a theory-based empirical examination of a crisis event and its aftermath to understand how hindsight can be sharpened and then used to improve organizational foresight.  相似文献

Risk management in an organization represents a decisive function in seizing opportunities and managing the risks that can affect a business's reputation, prosperity, growth, value creation, stakeholder engagement, long-term survival, and a firm's contribution to sustainable development. For this paper, we conduct a systematic literature review of 148 indexed studies and uses the “Six Ws” (what, who, why, where, when, and how) approach to understand the linkages between sustainability and risk management. This study's findings reveal that the management of environmental, social, and governance (ESG) concerns plays a mitigation's function on business risks.  相似文献

The authors discuss how policy-makers could use new market-based solutions to dismantle NPLs. They examine viable solutions for NPLs and then study the Italian State Guarantee Scheme for NPL Securitization (GACS) to highlight how public actors could efficiently use public resources to solve the NPL problem.  相似文献

Using quarterly data for a panel of advanced economies, we show that synchronized fiscal consolidation (stimulus) programmes in different countries make their business cycles more closely linked. We also find: (i) some evidence of decoupling when an inflation targeting regime is unilaterally adopted; (ii) an increase in business cycle synchronization when countries fix their exchange rates and become members of a monetary union; (iii) a positive effect of bilateral trade on the synchronization of business cycles. Global factors, such as a rise in global risk aversion and uncertainty and a reversal of nonstandard expansionary monetary policy, can also reduce the degree of co‐movement of business cycles across countries. From a policy perspective, our work shows that an inflation targeting regime coupled with simultaneous fiscal consolidations can lead to more business cycle synchronization.  相似文献

The profound financial crisis generated by the collapse of Lehman Brothers and the European sovereign debt crisis in 2011 have caused negative values of government bond yields both in the USA and in the EURO area. This paper investigates whether the use of models which allow for negative interest rates can improve option pricing and implied volatility forecasting. This is done with special attention to foreign exchange and index options. To this end, we carried out an empirical analysis on the prices of call and put options on the US S&P 500 index and Eurodollar futures using a generalization of the Heston model in the stochastic interest rate framework. Specifically, the dynamics of the option’s underlying asset is described by two factors: a stochastic variance and a stochastic interest rate. The volatility is not allowed to be negative, but the interest rate is. Explicit formulas for the transition probability density function and moments are derived. These formulas are used to estimate the model parameters efficiently. Three empirical analyses are illustrated. The first two show that the use of models which allow for negative interest rates can efficiently reproduce implied volatility and forecast option prices (i.e. S&P index and foreign exchange options). The last studies how the US three-month government bond yield affects the US S&P 500 index.  相似文献
