We investigate the intertemporal relation between information asymmetry and equity issues, and particularly focus on which firms drive this relation. We find that when information asymmetry for a particular firm is low compared to the recent past, the firm is more likely to issue equity as opposed to debt. Importantly, this intertemporal association is driven by firms with high levels of information asymmetry. These firms are more prone to adverse selection costs and thus have more to gain by issuing equity after a narrowing of the information gap between managers and investors. Our findings are robust to various firm-specific proxies for information asymmetry.  相似文献

There are numerous ways to indicate the degree of banking competition across countries. Antitrust authorities rely on the structure-conduct-performance paradigm while academics prefer price mark-ups (Lerner index) or correlations of input costs with output prices (H-statistic). These measures are not always strongly correlated within or across countries. Frontier efficiency analysis is used to devise an alternative indicator of competition and rank European countries by their dispersion from a “competition frontier”. The frontier is determined by how well payment and other costs explain variations in loan-deposit rate spread and non-interest activity revenues. Overall, differences in competition appear to be small.  相似文献

We investigate whether or not there is a link between conservative accounting practices and the sensitivity of executive pay to accounting performance. Using several accrual‐based measures of accounting conservatism as well as alternative measures of accounting performance, we estimate an econometric model of CEO compensation that incorporates the interaction of accounting conservatism and accounting performance. Consistent with optimal contracting theory, we find that the sensitivity of executive pay to accounting performance is higher for firms that report conservative accounting earnings. These results support the hypothesis that accounting conservatism, by limiting earnings management opportunities and improving the reliability of accounting performance measures, allows firms to formulate contracts that tie executive compensation more closely to accounting performance.  相似文献

We identify finance professors’ opinions on the efficiency of the stock markets in the United States and assess whether their views on efficiency influence their investing behavior. Employing a survey distributed to over 4,000 professors, we obtain four main results. First, most professors believe the market is weak to semi-strong efficient. Second, twice as many professors passively invest than actively invest. Third, our respondents’ perceptions regarding market efficiency are almost entirely unrelated to their trading behavior. Fourth, the investment objectives of professors are, instead, largely driven by the same behavioral factor as for amateur investors–one's confidence in his own abilities to beat the market, independent of his opinion of market efficiency.  相似文献

Newly public companies must disclose significant risk factors in the offering prospectus. These disclosures are examples of “soft” or ambiguous information. Ambiguity models predict that investors will alter their portfolio weights and react to subsequent signals about such information. We test for these effects in a sample of 1,398 initial public offerings (IPOs) using word count ratios between soft and hard information as measures of ambiguity. We find a significant relationship between the soft information on risk and both initial and ex post measures of returns. These results support the view that soft information embeds ambiguity and that it influences investors’ portfolio choices.  相似文献

Seasoned equity offering (SEO) underpricing has increased dramatically since the early 1980s. While previous research has examined the determinants of SEO underpricing, these studies have not explored the effect of insider ownership on discounts. We find that this effect is twofold. First, higher insider ownership reduces float, thereby increasing price pressure and SEO underpricing. This effect is greatest in firms with low liquidity. Second, the greater the percentage of secondary shares offered, the lower the underpricing, suggesting that manager's pressure banks to reduce underpricing when their personal wealth is at stake. However, we find that this negative relation is mitigated if the firm employs a prestigious underwriter.  相似文献

The operating agreements of many business ventures include clauses to facilitate the exit of joint owners. In so‐called Texas Shootouts, one owner names a single buy‐sell price and the other owner is compelled to either buy or sell shares at that named price. Despite their prevalence in real‐world contracts, Texas Shootouts are rarely triggered. In our theoretical framework, sole ownership is more efficient than joint ownership. Negotiations are frustrated, however, by the presence of asymmetric information. In equilibrium, owners eschew buy‐sell offers in favor of simple offers to buy or to sell shares and bargaining failures arise. Experimental data support these findings.  相似文献

Previous research has examined the demand for life insurance policy loans using aggregate policy loan data. In contrast, we use a detailed household survey data set containing life insurance and policy loan information to alternatively, and in some cases more directly, examine the four hypotheses traditionally associated with policy loan demand. Our research provides the first U.S. evidence (in the post–World War II period) in support of the policy loan emergency fund hypothesis. In particular, we find that the more detailed emergency fund proxies used here reveal a significantly positive relation between loan demand and recent expense or income shocks.  相似文献

In an earlier edition of this journal, we published evidence relating to the nature of discount rates chosen by a sample of large Australian‐listed firms in the context of their goodwill impairment testing ( Carlin and Finch 2009 ). We argued that our evidence suggested that the rigour of the International Financial Reporting Standards (IFRS) goodwill impairment testing process was being undermined by inappropriate choice of discount rates on the part of many firms. In a commentary published alongside our article, questions were raised as to the validity of our conclusions and the methodology we applied in our study ( Gallery 2009 ). Subsequently, Bradbury has also contributed to the debate, raising similar concerns to those voiced by Gallery ( Bradbury 2010 ). In this brief paper, we provide further and better particulars in relation to our original dataset in a bid to assist those who have taken an interest in this debate to further inform their view of the merits (or otherwise) of the case we made in our original article.  相似文献

This paper points to some limitations of the narrow version of integral futures (IF) as represented in the recent special issue of Futures (2008, vol. 40, issue 2). I also propose several ways that the IF brand could be refreshed through a broader and deeper approach to integral futures by way of a scholarly engagement with other kindred discourses. The main focus of this paper is to open out beyond the “myth-of-the-given” in relation to the notion of integral and in this way broaden and deepen possibilities for integral futures.  相似文献
