To understand why investors hold socially responsible mutual funds, we link administrative data to survey responses and behavior in incentivized experiments. We find that both social preferences and social signaling explain socially responsible investment (SRI) decisions. Financial motives play less of a role. Socially responsible investors in our sample expect to earn lower returns on SRI funds than on conventional funds and pay higher management fees. This suggests that investors are willing to forgo financial performance in order to invest in accordance with their social preferences. 相似文献

We develop a bid‐ask spread estimator from daily high and low prices. Daily high (low) prices are almost always buy (sell) trades. Hence, the high–low ratio reflects both the stock's variance and its bid‐ask spread. Although the variance component of the high–low ratio is proportional to the return interval, the spread component is not. This allows us to derive a spread estimator as a function of high–low ratios over 1‐day and 2‐day intervals. The estimator is easy to calculate, can be applied in a variety of research areas, and generally outperforms other low‐frequency estimators. 相似文献

This paper shows that low-risk anomalies in the capital asset pricing model and in traditional factor models arise when investors require compensation for coskewness risk. Empirically, we find that option-implied ex ante skewness is strongly related to ex post residual coskewness, which allows us to construct coskewness factor-mimicking portfolios. Controlling for skewness renders the alphas of betting-against-beta and betting-against-volatility insignificant. We also show that the returns of beta- and volatility-sorted portfolios are driven largely by a single principal component, which in turn is explained largely by skewness. 相似文献

We examine whether a simple quantitative measure of language can be used to predict individual firms' accounting earnings and stock returns. Our three main findings are: (1) the fraction of negative words in firm-specific news stories forecasts low firm earnings; (2) firms' stock prices briefly underreact to the information embedded in negative words; and (3) the earnings and return predictability from negative words is largest for the stories that focus on fundamentals. Together these findings suggest that linguistic media content captures otherwise hard-to-quantify aspects of firms' fundamentals, which investors quickly incorporate into stock prices. 相似文献

This paper offers a new approach that estimates the response of interest rates to inflation and the output gap at various points (quantiles) on the conditional distribution of interest rates. This offers an improvement on empirical estimates conducted only at the mean and also allows us to test the propositions that policy shows greater aggression to inflation in the reaction function in terms of a greater response coefficient as interest rates reach low levels, and increasing aggression as the lower bound is approached. We find support for the Taylor principle, a more aggressive response to inflation than under a Taylor rule, but no detectable evidence of increasing aggression as the zero lower bound is approached in the US and Japan. 相似文献

We use machine learning for relative valuation and peer firm selection. In out-of-sample tests, our machine learning models substantially outperform traditional models in valuation accuracy. This outperformance persists over time and holds across different types of firms. The valuations produced by machine learning models behave like fundamental values. Overvalued stocks decrease in price and undervalued stocks increase in price in the following month. Determinants of valuation multiples identified by machine learning models are consistent with theoretical predictions derived from a discounted cash flow approach. Profitability ratios, growth measures, and efficiency ratios are the most important value drivers throughout our sample period. We derive a novel method to express valuation multiples predicted by our machine learning models as weighted averages of peer firm multiples. These weights are a measure of peer–firm comparability and can be used for selecting peer-groups. 相似文献

The aim of this paper is to trace and explain variations in calculative and collaborative human resource management (HRM) practices between companies and across national borders. Variations and similarities are explained in terms of the convergence and divergence of HRM practices determined by national institutions, and the increasing influence of multinational companies (MNCs). We explore the diffusion of HRM practices in Europe over time, using data sets from two surveys conducted in several European countries in 1995 and 2000. We use institutional explanations for the development of three selected bundles of HRM practices: individual, calculative performance‐oriented practices; collective incentive schemes for the alignment of interests; and collaborative practices that seek to enhance the commitment of employees. We found substantial effects of country‐specific institutions and of the country of origin of MNCs, which clearly support the institutional duality thesis. Foreign‐owned MNCs, especially those that are US‐based, appear to moderate country‐specific institutional effects on the diffusion of the three HRM bundles. 相似文献

The introduction of the European Directive on Information and Consultation and the recent implementation of the Information and Consultation of Employees (ICE) Regulations into United Kingdom (UK) law have increased the focus on workplace representation arrangements. This paper examines the interplay between nonunion and union representative arrangements at Eurotunnel (UK) and assesses their effectiveness in representing the needs of employees over a 5‐year period. Importantly, the paper also examines the opportunities and challenges of both nonunion representation (NER) and union voice arrangements. The findings show that the effectiveness of nonunion structures as bodies representing the interests of employees in filling the lack of representation is questionable. However, union recognition through an employer–union partnership agreement has also raised important issues regarding the effectiveness, impact, and legitimacy of unions at Eurotunnel. The main implication of this research is that the existence of a mechanism—union or nonunion—for communication between management and employees at the workplace may not be a sufficient condition for effective representation of employee interests. In addition, while trade unions may provide greater voice than nonunion arrangements (thus the reluctance of management to accept such voice arrangements), the strength of voice is dependent on the legitimacy and effectiveness of trade unions in representing employees’ interests at the workplace. And that in turn depends on the union being perceived by the workforce as both representative and able to act independently. If the union cannot, it will not meet the needs of either employees or management—and could run the risk of being supplanted under the provisions of the new EU Directive on Information and Consultation with tougher requirements for compliance in terms of procedures for consultation and information disclosure. 相似文献
