Human-mediated seed dispersal is recognised as an important, but under-researched, issue. To assess the potential for tourists to act as unintentional seed dispersal agents, we reviewed published and unpublished data on seed dispersal via clothing, vehicles (cars) and in/on horses and donkeys, all of which can be used by tourists. Seeds from 754 species of terrestrial plants have been collected from these vectors, 15% of which are internationally recognised environmental weeds. Seeds were collected from personal clothing and equipment (228 species), the fur of donkeys and horses (42 species), horse dung (216 species) and vehicles (505 species). Most were herbs (429 species) or graminoids (237 species) and native to Europe. Annual Poa, White Clover, Kentucky Bluegrass and Yorkshire Fog were the most frequent species. There have been eight studies specifically on tourists, which identified 12 species on clothing, 26 on vehicles and 133 from horse dung. Methods that minimise the risk of tourists as human-mediated dispersal agents may therefore be appropriate for some tourism activities/destinations: suggestions are made. Further sampling using standardised experimental techniques is required to assess the relative risk associated with specific tourist activities and locations and determine which, and how much, seed is transported. 相似文献

We investigate the disclosure of non-IFRS performance measures by 400 companies from eight countries using IFRS Standards (Australia, France, Germany, Hong Kong, Italy, Singapore, Sweden and the United Kingdom) in the years 2005, 2008, 2011 and 2013 (1595 company-years). The incidence of disclosure is higher in UK and France but lower in Hong Kong, Germany and Singapore. Exclusions relating to impairment, tax, and mergers and acquisitions are frequent. Firms making non-IFRS disclosures are more likely to be larger, have higher leverage, and exhibit greater volatility in their reported income. Additional tests show national reporting traditions and practices affect non-IFRS disclosures. 相似文献

Do banks matter for the risk of a firm's investment portfolio? Evidence from foreign direct investment programs 下载免费PDF全文
Marie‐Ann Betschinger 《战略管理杂志》2015,36(8):1264-1276
The study explores the role of banks as debt and equity holders for the riskiness of a firm's investment strategy using a panel of Japanese firms in the electronics industry in the period 1992–2004 for the empirical analysis. Based on a conceptual framework grounded in agency and financial intermediation theories, we find that a larger involvement of banks as debt holders in a firm is associated with lower foreign direct investment portfolio risk, while the shareholdings of universal banks increase it, supporting the theoretical predictions.

Research summary: We show that private equity ownership (“PE backing”) of the acquirer is a signal of deal quality in cross‐border takeovers. As such, PE‐backed acquirers experience higher announcement returns in cross‐border takeovers, but only if targets are in poor information environments. We show that PE backing is a positive market signal because of PE firms' experience and networks that result from prior deals in target countries. We document that the market correctly anticipates that operating performance of PE‐backed acquirers increases as a result of cross‐border mergers and acquisitions (M&A). Managerial summary: We study cross‐border acquisitions by acquirers that are partially owned by private equity firms (“PE backing”). Cross‐border acquisitions are challenging as acquirers often have little information about targets. We document that investors react positively to cross‐border deals of PE‐backed acquirers—their stock prices increase upon deal announcements. However, this is only the case if targets are in countries with poor information environments. This is because PE backing allows acquirers to access PE firms' deal experience and networks. This makes it easier to identify and evaluate good targets, making it more (less) likely that a deal eventually creates (destroys) value. Consistent with this, we find that earnings of PE‐backed acquirers increase after buying targets in poor information environments. Copyright © 2016 John Wiley & Sons, Ltd. 相似文献

What is the relationship between niche and performance? We identify two types of niche positions—product niche and process niche—defined by the extent to which a firm offers distinctive products and has distinctive operational processes, respectively. We argue that the effect of each niche on firm performance is contingent upon network embeddedness—the extent to which a firm is involved in a network of interconnected inter‐firm relationships. Using data covering the period 1995–98 pertaining to venture capital firms and their holdings in initial public offerings (IPOs), we show that both product niche and process niche interact with network embeddedness to determine firm performance. Our findings suggest that the extent to which a firm offers distinctive products or processes will be more positively associated with firm performance when network embeddedness is high.

The purpose of this article is to provide an overview of the literature on what we currently know about the costs and benefits of auditing private company accounts. Our main conclusions are the following. First, there is much heterogeneity in factors driving audit demand in private companies and the value derived from the audit. Second, research provides support for improved financial reporting quality due to, and real economic benefits from, private company audits. Third, the cost–benefit analysis for private company audits is firm-specific and mandating the audit does not seem to be cost-effective and thus economically optimal for all private companies. Alternative services may better meet the needs of especially smaller private companies. Furthermore, mandating the audit is not necessarily an optimal solution since private companies with low demand for a high-quality audit are able to find an auditor that meets their requirements even under a mandatory regime. Hence, having a mandatory audit in place is no guarantee for universally high-quality audits and this seems most salient for private companies where auditors may be more prone to independence issues. We conclude by providing a number of directions for future research. 相似文献

We analyze credit watch and rating actions to better understand the role of credit watches in the credit rating process. We find that watch actions are more frequently prompted by specific, publicly known events than are rating actions. The likelihood that a watch action precedes a rating action varies systematically with proxies for investor demand for credit quality information and the adverse consequences of issuing a rating change prematurely. Credit watches occur more often in response to deterioration in credit quality, and issuers make concerted efforts to address the concerns that prompted down watches. Down watches are less likely than up watches to indicate the direction of the subsequent rating change. Watch announcements are associated with abnormal stock returns, indicating that credit watch actions are significant information events. Our results suggest that credit watches are informative and facilitate the stability of ratings by allowing firms to correct deficiencies and prevent downgrades. 相似文献

Using a unique proprietary data set of over 5400 realized and unrealized venture capital investments between 1980 and 2005, we examine the impact of demand-related factors, e.g. entrepreneurial activity, as well as supply-related factors, i.e. money provided by VC investors, on the return of individual VC investments. This way, we are able to shed more light on the question whether volatile VC investment returns are rather driven by fundamental changes with regard to the number of attractive investment opportunities or by the overreaction by investors. We find that rising demand for VC, i.e. an increase in entrepreneurial activity, results initially in higher returns. However, our results also indicate that overreaction on the supply side can be observed, destroying deal-level results. Overfunding, specifically overinvesting seems to be a recurring characteristic of the VC industry. In fact, contra-cyclical investment strategies yield highest deal-level returns. 相似文献

This study examines the relationship between use of international accounting standards and companies’ source of finance. We investigate the proposition contained in Nobes’ (1998) model that postulates outsider companies (those with a higher level of public finance) in weak equity–outsider markets (capital markets where public equity finance is not the dominant source of finance) are more likely to change their type of accounting system from one focused on information for creditors and tax authorities to one that meets the needs of external financiers. We found strong support for Nobes’ model. Using 408 German listed companies at 1999, we observed that companies with more outsider finance (the proportion of shares held by outsiders and the presence of public debt) were more likely to use international standards (U.S. GAAP or IAS). The results indicate the importance of controlling for source of finance at the company rather than country level in cross‐country studies investigating the benefits of adoption of international standards. 相似文献
