We analyze the institutional determinants of U.S. financial market regulation with a general model of the policy-making process in which legislators delegate authority to regulate financial risk at both the firm and systemic levels. The model explains changes in U.S. financial regulation leading up to the financial crisis. We test the predictions of the general model with a novel, comprehensive data set of financial regulatory laws enacted specifically between 1950 and 2009. The theoretical and empirical analysis finds that economic and political factors impact Congress’ decision to delegate regulatory authority to executive agencies, which in turn impacts the stringency of financial market regulation, and our estimation results indicate that political factors may have been stronger and resulted in inefficiencies. 相似文献

基于2005—2018年中国内地285个地级市数据,对城市科技人才集聚与全要素生产率(简称“TFP”)进行测度分析,实证考察科技人才集聚对TFP的影响。结果表明:①城市科技人才集聚与TFP空间分异特征显著,但二者具有较强的时空一致性,即科技人才集聚特征显著的城市,其TFP也相对稳定;②城市科技人才集聚对TFP的影响呈倒U型,但研究期内大多数城市仍处于集聚效应占主导阶段,科技人才集聚通过提升城市技术进步水平促进TFP增长,而科技人才集聚对技术效率的影响呈倒U型;③不同类型城市科技人才集聚对其TFP影响的异质性显著,且适宜集聚区间也存在差异。省会城市及一、二线城市等优势特征显著的城市所能承受的科技人才集聚规模上限更高,有利于通过释放集聚红利促进TFP增长,而非省会城市、三线及以下城市等则拐点值较低。 相似文献

We examine the effect of a regulator-led advocate for minority shareholders on merger and acquisition (M&A) performance in China. In recent years, the China Securities Regulatory Commission established the China Securities Investor Services Center (CSISC), which began its ownership of 100 shares of public firms in 2016. The CSISC advocates for the interests of minority shareholders proactively. Focusing on abnormal stock returns in M&A announcements, we find that acquirers that have the CSISC as a shareholder (CSISC acquirers) exhibit higher positive abnormal stock returns than non-CSISC acquirers. Cross-sectional analysis suggests that the core results are mainly driven by firms with severe agency problems and weak external/internal monitoring, and those not controlled by the state. In addition, we find that CSISC acquirers have better long-term performance and encounter more M&A failures than non-CSISC acquirers. Our findings indicate that although the CSISC only holds 100 shares of listed companies, it plays an effective role in monitoring and driving firms to make appropriate M&A decisions. 相似文献

The legal and compliance departments in organizations have more influence than ever before. Why then are companies so vulnerable to legal liability? The problem may not be with talented legal professionals, but with the lack of legal knowledge held by MBAs and other business school graduates that make day-to-day decisions in modern organizations. Firms can close this knowledge gap and minimize legal liability by training their managers in legal astuteness—the ability of a manager to address legal issues successfully—by instilling four essential traits: respecting the rule of law, recognizing legal issues, resolving problems proactively, and reporting complex legal issues to experts. Job candidates should also be screened for traits of legal astuteness. A legally astute candidate, especially a graduate of a business school that requires legal education for all its students, can be a cultural ambassador for legal astuteness and a valuable liaison between legal and compliance departments and the candidate’s functional area. A legally ignorant candidate will require significant training and a frank assessment of the legal risk they bring to the organization. Modern firms in today’s legal environment face two choices: hire a legally astute manager now or deal with a compliance headache later. 相似文献

We suggest that the distortion of the positive risk–return relation in the ICAPM is a consequence of trading by informed investors to exploit mispricing. We hypothesize and demonstrate that a non-positive (strongly positive) risk–return relation following positive (negative) market returns is attributed to short-selling (purchasing) of overpriced (underpriced) stocks along with optimistic (pessimistic) expectations conditional on good (bad) market news. We verify this asymmetry in the risk–return relation through the indirect risk–return relation conditional on good (bad) market news. We also find that the attenuation (reinforcement) of the positive risk–return relation is more profound in high- (low-) sentiment periods. 相似文献

This study explores the conditional version of the capital asset pricing model on sentiment to provide a behavioural intuition behind the value premium and market mispricing. We find betas (β) and the market risk premium to vary over time across different sentiment indices and portfolios. More importantly, the state β derived from this sentiment-scaled model provides a behavioural explanation of the value premium and a set of anomalies driven by mispricing. Different from the static β–return relation that gives a flat security market line, we document upward security market lines when plotting portfolio returns against their state βs and portfolios with higher state βs earn higher returns. 相似文献

This study details how psychological, financial, and social factors shape employee deviant interpersonal behaviors during a pandemic. Data were collected with a survey of 372 front-line employees of hotels and analyzed with PLS-SEM. The findings showed social disconnectedness and perceived risk of unemployment leads to perceived isolation, which further creates depression in employees. The findings also showed that depression is positively related to employee deviance. Financial strain is a major cause of perceived isolation, depression, and deviant behaviors among front-line employees. Results also proved that social support reduces fear of isolation, depression, and employee deviance. This study provides guidelines that hotels need to understand the psychological stance of employees and design policies to overcome employee perceived fears and psychological disorders. 相似文献
