This is the first study to document evidence of technical trading effectiveness at firm level in the Chinese A-share market by investigating the relationship between excess profits of technical trading rules and firm-specific characteristics. Our results reveal that firms with higher excess profits from technical trading have more noise traders and higher institutional ownership and that those firms tend to be growth firms with lower liquidity and higher firm-specific uncertainty. Further analysis shows that the profitability of technical trading rules is unsustainable and the excess profits of the highest technical trading profit quintile portfolio disappear in the following year. 相似文献

Sequels have become a profitable strategy in the U.S. motion picture industry because of their strong name recognition. However, while the established positioning of a sequel may help insulate it from competing firms' advertising messages, its familiarity may cause moviegoers to be more easily satiated with advertising from the sequel. Therefore, this study examines how sequels differ from original concept movies in terms of their ad effectiveness. We focus our analysis on pre-launch periods, given these periods' importance in shaping the financial outcomes of motion pictures. We consider the weekly online search volume of a movie as a measure of consumer interest in it, and thus as an intermediate response to pre-launch advertising. We then develop a model that assumes ad effectiveness can decline, due to copy and repetition wearout, and increase, due to forgetting, over time. We find that copy wearout is greater for original movies, while repetition wearout and forgetting are greater for sequels. These findings suggest that sequels should allocate more in early pre-launch periods and less immediately before release, relative to originals, to maximize pre-launch consumer interest. 相似文献

This study presents analysis of the impact of “official product” sports sponsorships with the National Football League (NFL),
Major League Baseball (MLB), the National Hockey League (NHL), the National Basketball Association (NBA), and the Professional
Golfers Association (PGA) on the stock prices of sponsoring firms. The primary finding of the study is that, in the main,
announcements were accompanied by increases in shareholder wealth. The 53 sponsors analyzed experienced mean increases in
stock valuations of about $257 million. A multiple regression analysis of firm-specific stock price changes and selected corporate
and sponsorship attributes indicates that official product sponsorships with the NBA, NHL, and PGA and those with smaller
market shares were associated with the largest gains in share prices. Although corporate cashflow (a proxy for agency conflicts)
is statistically unrelated to shareholder approval, sponsorships by high-technology companies were associated with stronger
stock price reactions than otherwise. Finally, product congruence with the sponsored sport was positively related to changes
in stock prices.

This study examines whether corporate social responsibility (CSR) committees associate with the external assurance of CSR reports. Specifically, we consider the presence and effectiveness of CSR committees. Using a sample of Australian firms over the period 2004–2016, we show the mere presence of a CSR committee is not related to the external assurance of CSR. However, CSR committee effectiveness is positively related. In addition, firms with higher CSR committee effectiveness are more likely to seek external assurance provided by the Big4 accountancy firms and acquire financial audit and CSR assurance services from the same provider. Taken together, CSR committee effectiveness plays an active role in CSR assurance services. Our results are particularly relevant to those with interests in understanding the demand and choice of external CSR assurance services, as well as the impact of corporate governance mechanisms on these services. 相似文献

Trade policy barriers and high transaction costs hinder developing countries from taking the full advantages of the global trading system. In order to help developing countries overcome the problem, the World Trade Organization (WTO) launched the Aid for Trade (AFT) initiatives in its Ministerial Conference held in Hong Kong in 2005. We examine the effects of AFT inflows on bilateral trade costs facing 133 developing countries while accounting for differences in their location on the contours of various measures of institutional quality. Our results from the estimation of a mixed effects (random-intercept and random-coefficient) model indicate that institutional quality significantly affects the extent to which AFT reduces bilateral trade costs. An important policy implication of our findings is that an economically robust and sustainable reduction in bilateral trade costs facing developing countries requires the presence of both promulgated and effectively functioning institutions such as regulatory power and the rule of law. 相似文献
