This paper examines hedging against a large market-wide shock in a model with heterogeneous firms and sunk costs of entry. If hedging is voluntary only the most efficient firms hedge against this shock, a finding in line with empirical evidence but at odds with standard motivations for risk management. Hedging affects the critical level of the marginal cost needed to operate in the market. A setting with mandatory hedging is associated with stronger competition than when hedging is voluntary which, in turn, is associated with stronger competition than when hedging is unavailable. 相似文献

We use machine learning with a cross-sectional research design to predict governance controversies and to develop a measure of the governance component of the environmental, social, governance (ESG) metrics. Based on comprehensive governance data from 2,517 companies over a period of 10 years and investigating nine machine-learning algorithms, we find that governance controversies can be predicted with high predictive performance. Our proposed governance rating methodology has two unique advantages compared with traditional ESG ratings: it rates companies' compliance with governance responsibilities and it has predictive validity. Our study demonstrates a solution to what is likely the greatest challenge for the finance industry today: how to assess a company's sustainability with validity and accuracy. Prior to this study, the ESG rating industry and the literature have not provided evidence that widely adopted governance ratings are valid. This study describes the only methodology for developing governance performance ratings based on companies' compliance with governance responsibilities and for which there is evidence of predictive validity. 相似文献
