We examine the relation between corporate liquidity and political connections measured via lobbying expenditures. This is an interesting question as many of the motives for holding cash should be diminished by political connections. Results indicate a significant and inverse relation between cash levels and lobby expenses and that the marginal value of cash decreases with lobbying. Taken together, these findings suggest firms react optimally to the reduced benefits of cash linked to political connections and that the market recognizes the weakened benefits of cash. Overall, our research shows another way political connections can shape corporate policy. 相似文献

Researchers often form ratios of variables to measure firm characteristics, but which ratios create the most powerful tests? For example, if we use ratios of book value of equity (BE) and market value of equity (ME), or earnings (E) and price (P), does it matter which variable appears in the denominator? Any variable in the denominator, when close to zero, creates outliers and is less likely to produce effective tests. Our tests, using data from 1972 to 2008, indicate the choice between reciprocals often produces significantly different outcomes. While ME/BE is a more commonly used control variable than BE/ME or LN(BE/ME), we find the latter two produce better results, even if the data are trimmed to mitigate the outlier problem. Similarly, using E/P generally produces better results than P/E, and while ratios with book value of assets (BA) in the numerator work better than those with it in the denominator, the difference is less pronounced than when BE or E is part of the ratio. While the focus of our empirical findings is on growth measures, the principal applies anytime a ratio has a denominator that is frequently near zero. 相似文献

Patents serve as an indicator of the innovation capability of countries, industries, or firms. Many Indian firms are in a transition to move from labor intensive segments to areas with higher value added which has been reflected in this research. The purpose of this study is to analyze patents issued during the period of 1997–2009 from the European Patent Office database and the United States Patent and Trademark Office database from the top one hundred Indian information technology firms. This study represents a novel empirical look at information technology industry innovations in India. A comprehensive set of statistical patent analyses are presented to provide practitioners with valuable knowledge to assist in business strategic planning. 相似文献

Using an expansion of the transition density function of a one‐dimensional time inhomogeneous diffusion, we obtain the first‐ and second‐order terms in the short time asymptotics of European call option prices. The method described can be generalized to any order. We then use these option prices approximations to calculate the first‐ and second‐order deviation of the implied volatility from its leading value and obtain approximations which we numerically demonstrate to be highly accurate. 相似文献

Consumers assess the credibility of online product reviews to guide their purchase decisions. However, little is known about how consumers determine the credibility of online product reviews. This article examines the effect of the level of detail in a product review and the level of reviewer agreement with it on the credibility of a review and consumers' purchase intentions for search and experience products. Overall, the results indicate that more credible reviews lead to higher purchase intentions. Interestingly, the findings also demonstrate that consumers determine the credibility of a review differently for search and experience products. For search products, consumers deem online reviews to be more credible when the reviews contain detailed information about the product. However, for experience products, consumers determine the credibility of a review by assessing the level of reviewer agreement with a review. The lack of diagnosticity of detailed information in online reviews of experience products is attributed to the idiosyncratic nature of experiences. Implications for research and practice are discussed. 相似文献

Personal presentation attributes have long been understood to affect perceptions of competence and capabilities. To that end, this study investigates seven attributes associated with favorable interview presentation, including overall physical attractiveness, neatness and grooming, clothing color, conservative versus trendy attire, professional versus casual attire, and body modification (including tattoos and piercings). Participants (n = 108), including students, faculty, and hospitality industry professionals, sorted an orthogonal array of 16 full-color, laminated cards that contained photos so that respondents could see levels of clothing color, clothing conservativeness, and degree of professional attire. The remaining attributes and their corresponding levels were shown on respective analog indicators. The conjoint analysis results indicate that grooming and professional attire are the most important attributes in shaping favorable perceptions. Furthermore, faculty perceived conservative clothing to be better while students and industry professionals indicated that trendy clothing creates a more favorable presentation on the part of a job candidate. 相似文献

While Chenoweth and Feitelson have done a service to the futures community by comparing the Global 2000 Report with The Resourceful Earth-two important books of the late 1970s/early 1980s—their comparison is flawed in three dimensions: (1) they treat the books as though they were intended to be accurate predictions of the future. Their intention, instead, was to influence public policy in certain, often contrasting, directions; (2) by using in 2000 the same data sources the two books used in the 1970s (rather than better data sources available now, but not then), the authors' comparative conclusions are often flawed; and (3) in spite of this, their own conclusions often do not seem to follow from the comparative data they present: using only the data the two authors present, The Resourceful Earth does not appear to have been more ‘accurate’ in ‘predicting’ the year 2000 than was the Global 2000 report. 相似文献
