More Than Words: Quantifying Language to Measure Firms' Fundamentals   总被引:3,自引:0,他引:3  
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

Price controls create opportunities for international arbitrage. Many have argued that such arbitrage, if tolerated, will undermine intellectual property rights and dull the incentives for investment in research‐intensive industries such as pharmaceuticals. We challenge this orthodox view and show, to the contrary, that the pace of innovation often is faster in a world with international exhaustion of intellectual property rights than in one with national exhaustion. The key to our conclusion is to recognize that governments will make different choices of price controls when parallel imports are allowed by their trade partners than they will when they are not.  相似文献

This paper presents the results from a field experiment that examines the effects of nonfinancial performance feedback on the behavior of professionals working for an insurance repair company. We vary the frequency (weekly and monthly) and the level of detail of the feedback that the 800 professionals receive. Contrary to what we would expect if these professionals conformed to the model of the Bayesian decision maker, more (and more frequent) information does not always help improve performance. In fact, we find that professionals achieve the best outcomes when they receive detailed but infrequent (monthly) feedback. The treatment groups with frequent feedback, regardless of how detailed it is, perform no better than the control group (with monthly and aggregate information). The results are consistent with the information in the latest feedback report being most salient and professionals in the weekly treatments overweighting their most recent performance, hampering their ability to learn.  相似文献

We investigate the employment consequences of private equity buyouts. We find evidence of higher job creation, on average, at the establishments operated by targets of politically connected private equity firms than at those operated by targets of nonconnected private equity firms. Consistent with an exchange of favors story, establishments operated by targets of politically connected private equity firms increase employment more during election years and in states with high levels of corruption. In additional analyses, we provide evidence of specific benefits experienced by target firms from their political connections. Our results are robust to tests designed to mitigate selection concerns.  相似文献

Using a matched sample of separately managed accounts (SMAs) and mutual funds (MFs) with the same portfolio manager and investment style, we find that concurrently managed MFs consistently underperform their SMA counterparts and generate more negative return gaps. Fund characteristics and liquidity betas fail to fully explain the underperformance. An event‐study analysis finds that the weights placed into top (bottom)‐performing stocks increase for existing SMAs (MFs) and negative return gaps increase for the MFs after the onset of concurrent management. We find that higher compensation collected by SMA fund managers are associated with more unseen managerial actions which positively contribute to the SMA return gap. Our results suggest that when managers concurrently manage both SMAs and MFs, they favor SMA performance over their MF performance.  相似文献

This paper studies an optimal insurance and reinsurance design problem among three agents: policyholder, insurer, and reinsurer. We assume that the preferences of the parties are given by distortion risk measures, which are equivalent to dual utilities. By maximizing the dual utility of the insurer and jointly solving the optimal insurance and reinsurance contracts, it is found that a layering insurance is optimal, with every layer being borne by one of the three agents. We also show that reinsurance encourages more insurance, and is welfare improving for the economy. Furthermore, it is optimal for the insurer to charge the maximum acceptable insurance premium to the policyholder. This paper also considers three other variants of the optimal insurance/reinsurance models. The first two variants impose a limit on the reinsurance premium so as to prevent insurer to reinsure all its risk. An optimal solution is still layering insurance, though the insurer will have to retain higher risk. Finally, we study the effect of competition by permitting the policyholder to insure its risk with an insurer, a reinsurer, or both. The competition from the reinsurer dampens the price at which an insurer could charge to the policyholder, although the optimal indemnities remain the same as the baseline model. The reinsurer will however not trade with the policyholder in this optimal solution.  相似文献

With the purpose of explaining professional audit costs in Swedish municipalities, we hypothesised that audit costs are partly driven by various signalling and monitoring incentives in order to manage stakeholder relationships. Our model of the determinants of audit costs was tested on data from Swedish municipalities, thus extending the study of audit costs to political organisations in a Scandinavian institutional context. The test supported to some extent the traditional propositions of organisational complexity, risk and market determinants, as well as the proposition of the political environment. Our results indicate that audit costs are used to signal accountability, thereby suggesting that audit as a signal could be managed without managing professional auditors.  相似文献

Bibliometrics is a fundamental field of information science that studies bibliographic material quantitatively. It is very useful for organising available knowledge within a specific scientific discipline. This study presents a bibliometric overview of accounting research using the Web of Science database, identifying the most relevant research in the field classified by papers, authors, journals, institutions and countries. The results show that the most influential journals are: The Journal of Accounting and Economics, Journal of Accounting Research, The Accounting Review and Accounting, Organizations and Society. It also shows that US institutions are the most influential worldwide. However, it is important to note that some very good research in this area, including a small number of papers and citations, may not show up in this study due to the specific characteristics of different subtopics.  相似文献

This paper analyses investors’ ability to identify if managers use corporate social responsibility as an entrenchment practice to conceal the risk of dismissal associated with managerial discretion and if this detection is determined by the level of investor protection orientation. Results based on an international database of 1949 companies show that investors and markets do not identify managerial entrenchment based on the promotion of sustainable practices, except when such entrenchment is developed by companies located in countries with strong investor protection. In these countries, investors identify and penalise such companies with lower financial performance.  相似文献
