We explore the impact of corporate social responsibility (CSR) ratings on sell‐side analysts' assessments of firms' future financial performance. We suggest that when analysts perceive CSR as an agency cost they produce pessimistic recommendations for firms with high CSR ratings. Moreover, we theorize that, over time, the emergence of a stakeholder focus shifts the analysts' perceptions of CSR. Using a large sample of publicly traded U.S. firms over 15 years, we confirm that, in the early 1990s, analysts issue more pessimistic recommendations for firms with high CSR ratings. However, analysts progressively assess these firms more optimistically over time. Furthermore, we find that analysts of highest status are the first to shift the relation between CSR ratings and investment recommendation optimism. Copyright © 2014 John Wiley & Sons, Ltd.  相似文献

In this study, we investigate the financial and monetary policy responses to oil price shocks using a Structural VAR framework. We distinguish between net oil-importing and net oil-exporting countries. Since the 80s, a significant number of empirical studies have been published investigating the effect of oil prices on macroeconomic and financial variables. Most of these studies though, do not make a distinction between oil-importing and oil-exporting economies. Overall, our results indicate that the level of inflation in both net oil-exporting and net oil-importing countries is significantly affected by oil price innovations. Furthermore, we find that the response of interest rates to an oil price shock depends heavily on the monetary policy regime of each country. Finally, stock markets operating in net oil-importing countries exhibit a negative response to increased oil prices. The reverse is true for the stock market of the net oil-exporting countries. We find evidence that the magnitude of stock market responses to oil price shocks is higher for the newly established and/or less liquid stock markets.  相似文献

An attempt is made to provide some insight into the determinants of manufaturing investment in Greece. For this purpose an accelerator-relative costs-profits model is used and both the putty-putty and putty-clay versions are examined. Estimates reveal that demand and profits factors play an important role in investment decision while the impact of relative inputs cost is significant mainly in the short run. Window regression experiments show that there is a dramatic fall in profits elasticity of investment and a corresponding increase in the significance of demend factor in the later periods.  相似文献

This study focuses on the wealth‐protective effects of socially responsible firm behavior by examining the association between corporate social performance (CSP) and financial risk for an extensive panel data sample of S&P 500 companies between the years 1992 and 2009. In addition, the link between CSP and investor utility is investigated. The main findings are that corporate social responsibility is negatively but weakly related to systematic firm risk and that corporate social irresponsibility is positively and strongly related to financial risk. The fact that both conventional and downside risk measures lead to the same conclusions adds convergent validity to the analysis. However, the risk‐return trade‐off appears to be such that no clear utility gain or loss can be realized by investing in firms characterized by different levels of social and environmental performance. Overall volatility conditions of the financial markets are shown to play a moderating role in the nature and strength of the CSP‐risk relationship.  相似文献

We formulate a model of preferences with non-addictive habits, where consumption is required to be non-negative at all times, but can fall below a “standard of living” index that aggregates past consumption. We study the consumption-portfolio problem taking account of the non-negativity constraint on consumption, and provide a constructive proof for the existence of an optimal policy on a finite time-horizon [0,T]. We show that the consumption constraint binds up to an endogenous stopping time τ∗∈[0,T], after which it remains slack until T. A decomposition of constrained consumption involving an Asian average-strike capped call-option is demonstrated.  相似文献

An investment model where firms mitigate adverse hold‐up effects using hiring and personnel policies is theoretically investigated and empirically scrutinized. While no evidence for the prediction of differing worker characteristics, other than gender, across firms is found, demand (firm) side factors are evident in the hiring process. Evidence on other personnel policies is consistent with theory, which predicts firms with high‐investment expenditures resist unions, utilize more temporary and shift‐time workers and conduct more multitask training. Wages in high‐investment firms are higher, more sensitive to unemployment and experience variables that exhibit greater effects than in low‐investment firms.  相似文献

ABSTRACT * : The author highlights the problems and prospects of public enterprises within the European Union, as well as the major adjustments considered necessary for these enterprises to fulfil their role. He argues that general criteria determining whether the production of goods and services should be in the public sector cannot be readily established in the European Union, since public supply does not solely depend on the specific economic characteristics of the particular good or service, but also on the prevailing social, cultural and economic conditions in each country, on the economic policy pursued, and on the structural characteristics of its private and public sectors, including entrepreneurial and trade union behaviour.  相似文献

An equity market is called diverse if no single stock is ever allowed to dominate the entire market in terms of relative capitalization. In the context of the standard Itô-process model initiated by Samuelson (1965) we formulate this property (and the allied, successively weaker notions of weak diversity and asymptotic weak diversity) in precise terms. We show that diversity is possible to achieve, but delicate. Several examples are provided which illustrate these notions and show that weakly-diverse markets contain relative arbitrage opportunities: it is possible to outperform or underperform such markets over any given time-horizon. The existence of this type of relative arbitrage does not interfere with the development of contingent claim valuation, and has consequences for the pricing of long-term warrants and for put-call parity. Several open questions are suggested for further study.Received: January 2004, Mathematics Subject Classification (2000): 60H10, 91B28; 60J55JEL Classification: G10We are grateful for the helpful remarks offered by seminar audiences at Columbia, Yale, Princeton, the Sloan School of MIT, Boston University, the Mathematical Institute in Oberwolfach, and the Universities of Athens, Connecticut/Storrs and Texas/Austin. Special thanks go to Professors Jérôme Detemple, Julien Hugonnier, Ralf Korn, Andrew Lo, Mark Lowenstein and Steven Shreve. We are also indebted to Dr. Adrian Banner for a number of discussions that helped sharpen our thinking about these problems, and to the referees and editors for suggestions that improved the exposition. A significant part of this work was completed in the spring semester of 2002, while the second author was on sabbatical leave at the Cowles Foundation for Research in Economics, Yale University. He is grateful to the Foundation for its hospitality.  相似文献
