In an arbitrage-free economy with non-zero bid-ask spreads the existence of payoffs whose price is lower than the price of a dominated payoff cannot be discarded in general. However, when the former price corresponds to trivial portfolios which involve buying or selling one unit of the basis assets, its presence, although not an arbitrage, is a severe market anomaly which we refer to as an inefficient quote. In an empirical study, we report evidence that indicates that in options markets both the frequency and the magnitude of these anomalies are substantial and we document puzzling patterns in their behavior. 相似文献

This paper investigates the determinants of a “successful” IPO from a corporate governance perspective upon a representative sample of European listings from 2000 to 2015. We use an extensive dataset of market performance, financial data, and corporate governance characteristics to run the investigation. Differently from previous studies, our analysis embraces both a short‐term perspective and a medium–long‐term perspective, where the board of directors seems to perform different tasks, moving from a value creation to a value protection strategy. Among the others, we find that board size, board independence, and their qualifications, together with their experience in other boards, are associated with a positive performance of the IPO in a short‐term horizon and in the medium–long‐term period, although significant differences emerge among those time perspectives. 相似文献

在企业纷纷实施高管年轻化战略的背景下,本文从股价崩盘风险的视角分析和检验了年轻高管风险偏好的经济后果及其作用机理。本文基于“个体认知观”和“代理冲突观”展开理论推演,采用中国沪深A股非金融上市公司的数据,检验发现,年轻高管会显著加剧企业未来的股价崩盘风险,且这种影响主要存在于民营企业,在国有企业并不显著。进一步针对具体作用机制的检验发现,年轻高管在投资决策中选择了更多能迅速提升个人收益的风险性投资项目,但在不能迅速提升个人收益的风险性投资项目上与年长高管没有显著差异。同时,年轻高管对股价崩盘风险的加剧效应仅仅存在于高管在上市公司领取薪酬的样本企业,且更高的独立董事比例能显著抑制年轻高管的股价崩盘风险加剧效应。这表明,年轻高管个体认知层面的风险偏好被其追求个人私利最大化的代理冲突所扭曲,进而为年轻高管风险偏好的“代理冲突观”提供了实证证据。 相似文献

Politicians frequently intervene in the regulation of financial accounting. Evidence from the accounting literature shows that regulatory capture by special interests helps explain these interventions. However, many accounting rules have broad economic or social consequences, such as their effects on income distribution or private sector subsidies. The perception of these consequences varies with a politician's ideology. Therefore, if accounting rules produce those consequences, ideology plausibly spills over and explains a politician's stance on the technical accounting issue, beyond special interest pressure. We use two prominent U.S. political debates about fair value accounting and the expensing of employee stock options to disentangle the role of ideology from special interest pressure. In both debates, ideology explains politicians’ involvement at exactly those points when the debate focuses on the economic consequences of accounting regulation (i.e., bank bailouts and top management compensation). Once the debates focus on more technical issues, connections to special interests remain the dominant force. 相似文献

This paper examines the relationship between cash holdings and performance in Italy over 36 years. Specifically, in light of the presence of conflicting evidence concerning the worth of cash stock, which could lead to a positive effect rather than a negative one, the role of moderating factors that can shape the magnitude of this relationship is investigated. The results show that the value of cash holdings is affected by firm‐specific characteristics, as well as factors related to the institutional context. Although other studies have analyzed moderators one at a time, this is the first work to consider how they jointly work. When the moderators are considered together, some of them become no longer statistically significant while others become even more economically and statistically relevant. 相似文献

AbstractUsing a hand-collected dataset, we examine share trading activity over the period 1882–1920 for the North British and Mercantile Insurance Company, one of the largest UK companies of the time. Our main finding is that the steady flow of rentiers into the shareholding constituency of this company stymied share trading activity. Another important finding is that share trading still occurred during the closure of the stock exchange in 1914, but on a much-reduced scale. We also find that there was a substantial boom in share trading and in insurance stock prices after World War I. 相似文献

In this paper, we examine the announcement effects of dividends with an emphasis on stock dividends in China's capital market. We find that dividend-paying stocks exhibit significantly positive abnormal returns while non-dividend-paying stocks show a negative announcement effect. Further, we document that the cumulative abnormal returns for pure stock dividends and combined dividends are the main drivers of this announcement effect. In contrast, pure cash dividend stocks experience no significant price run-up before announcement. The significant announcement effect of stock dividends is robust to controlling the earnings surprise effect. We offer some discussion of the possible explanations. 相似文献

We analyze the mechanism of return and volatility spillover effects from the Chinese to the Japanese stock market. We construct a stock price index comprised of those companies that have substantial operations in China. This China-related index responds to changes in the Shanghai Composite Index more strongly than does the TOPIX (the market index of the Tokyo Stock Exchange). This result suggests that China has a large impact on Japanese stocks via China-related firms in Japan. Furthermore, we find evidence that this response has become stronger as the Chinese economy has gained importance in recent years. 相似文献

On the day before the 2016 U.S. presidential election, the odds of Hillary Clinton winning the presidency, according to political prediction markets, were above 90%. Surprisingly, Donald Trump won the Electoral College handily. In this study, we examine how movements in specific stock prices foreshadowed the eventual outcome. Specifically, we conduct a series of standard event-study tests focused on pharmaceutical companies, which became a focal point during the presidential campaign. Results show that while stocks of pharmaceutical companies significantly underperformed the market prior to the election, prices substantially increased beginning three days before the election outcome. This increase is both statistically significant and economically meaningful and robust to various event-study methodologies. These results suggest that some sectors of the stock market seemed to anticipate the election outcome. 相似文献
