ADRs,Analysts, and Accuracy: Does Cross Listing in the United States Improve a Firm's Information Environment and Increase Market Value? 总被引:10,自引:0,他引:10
This paper investigates the relation between cross listing in the United States and the information environment of non‐U.S. firms. We find that firms that cross list on U.S. exchanges have greater analyst coverage and increased forecast accuracy than firms that are not cross listed. A time‐series analysis shows that a change in analyst coverage and forecast accuracy occurs around cross listing. We also document that firms that have more analyst coverage and higher forecast accuracy have higher valuations. Furthermore, the change in firm value around cross listing is correlated with changes in analyst following and forecast accuracy, suggesting that cross listing enhances firm value through its effect on the firm's information environment. Our findings support the hypothesis that cross‐listed firms have better information environments, which are associated with higher market valuations. 相似文献

In this study we examine the association among confirming management forecasts, stock prices, and analyst expectations. Confirming management forecasts are voluntary disclosures by management that corroborate existing market expectations about future earnings. This study provides evidence that these voluntary disclosures affect stock prices and the dispersion of analyst expectations. Specifically, we find that the market's reaction to confirming forecasts is significantly positive, indicating that benefits accrue to firms that disclose such forecasts. In addition, although we find no significant change in the mean consensus forecasts (a proxy for earnings expectations) around the confirming forecast date, evidence indicates a significant reduction in the mean and median consensus analyst dispersion (a proxy for earnings uncertainty). Finally, we document a positive association between the reduction of dispersion of analysts' forecasts and the magnitude of the stock market response. Overall, the evidence suggests that confirming forecasts reduce uncertainty about future earnings and that investors price this reduction of uncertainty. 相似文献

Debt in industry equilibrium 总被引:10,自引:0,他引:10
This article shows (1) how entry and exit of firms in a competitiveindustry affect the valuation of securities and optimal capitalstructure, and (2) how, given a trade-off between tax advantagesand agency costs, a firm will optimally adjust its leveragelevel after it is set up. We derive simple pricing expressionsfor corporate debt in which the price elasticity of demand forindustry output plays a crucial role. When a firm optimallyadjusts its leverage over time, we show that total firm valuecomprises the value of discounted cash flows assuming fixedcapital structure, plus a continuum of options for marginalincreases in debt. 相似文献

Profit-sharing and employee ownership in companies have attracted considerable interest, yet there has been little research on factors predicting the adoption and maintenance of these plans. This study uses new data from a survey of 500 US public companies, and panel data on corporate financial variables, to examine factors predicting the presence and adoption of profit- sharing and employee stock ownership plans (ESOPs) in the 1975–91 period. Several findings support productivity-related motivations for such plans (including higher R&D levels among old profit-sharing firms, and recent adoption of job enrichment programmes among new profit-sharing firms), while others support flexibility-related motivations (including higher variance in profits prior to the adoption of profit-sharing plans and ESOPs). Unionized firms were less likely to have either type of plan in 1975, but equally likely to adopt them subsequently (often in concessionary contracts). Comparisons of cross-sectional and panel results illustrate advantages of panel data in disentangling the causes and effects of profit-sharing and ESOPs. 相似文献

Previous findings that related diversification creates value have been called into question over concerns about methodology and measures. Reviewing existing theory to consider how a firm's knowledge base interacts with its product market activity, I address several of these concerns by creating a measure of technological diversity based on citation‐weighted patents. The measure indicates a firm's opportunity for corporate diversification based on economies of scope in valuable knowledge assets, is defined for both single‐ and multibusiness firms, and is not correlated with more fundamental aspects of diversification, such as the number of businesses in the corporate portfolio. Evidence from a large sample of firms shows the positive relationship between diversification based on technological diversity and market‐based measures of performance, controlling for R&D intensity and capital intensity as further indicators of the type of assets underlying diversification. Results hold when controlling for the endogeneity of diversification and performance in a cross‐sectional sample or when controlling for unobserved factors using panel data.

Employee Stock Options, Corporate Taxes, and Debt Policy 总被引:5,自引:0,他引:5
We find that employee stock option deductions lead to large aggregate tax savings for Nasdaq 100 and S&P 100 firms and also affect corporate marginal tax rates. For Nasdaq firms, including the effect of options reduces the estimated median marginal tax rate from 31% to 5%. For S&P firms, in contrast, option deductions do not affect marginal tax rates to a large degree. Our evidence suggests that option deductions are important nondebt tax shields and that option deductions substitute for interest deductions in corporate capital structure decisions, explaining in part why some firms use so little debt. 相似文献

Prior research into illegal goods has typically looked at one-way effects, such as illegal demand on legal demand. This research investigates a previously unexamined component of the market, illegal supply. The authors examine the supply and demand of legal goods and their illegal counterparts as a market system of four interdependent components. This research makes theoretical and empirical contributions by evaluating illegal supply in this system. Simultaneous equations estimate each market component on the others using data from the motion picture industry. The results find illegal supply has no effect on legal supply (movie screens), positive effects on illegal demand (piracy downloads), and some effect on legal demand (box office revenues). Timing effects highlight this: illegal supply has a positive effect on legal demand during a film’s opening week, but no effect post-launch. The other market components have positive effects on illegal supply (except legal supply, which is negative in the opening week). Additionally, illegal demand has a negative effect on legal demand during the opening week of release, but not in the subsequent weeks. This finding alleviates prior research tension as to whether piracy helps or hurts legal sales, as omitting illegal supply could result in biased estimates. 相似文献

Over the past decade, social media have become an increasingly important component in the ways broadcasters communicate with their audiences. A relative newcomer to that mix is the social network Pinterest, which enables followers to post photos and other types of visuals based on topics of interest. A content analysis examined how 85 local television stations are using that social network for promotion and branding. Results showed that, rather than promotion, use of Pinterest primarily revolves around lifestyle content, including postings by stations and interactivity by followers. 相似文献
