This study examines whether firms engage in income-decreasing real earnings management before open market stock repurchases to reduce the cost of stock buybacks. In the short run, managers have the ability to underproduce inventory and increase discretionary expenditures, thus decreasing current period earnings. We find that managers engage in both of these activities before repurchasing their firms’ shares, especially the latter. Also, companies increase their discretionary spending before making repurchases to a greater extent following the passage of the Sarbanes–Oxley Act of 2002 as well as when they are financially healthy and have high marginal tax rates. Finally, we document that firms with the most income-decreasing real earnings management experience the largest positive abnormal returns during the subsequent period. Our findings highlight the importance of considering firms’ use of real operating decisions, as opposed to just opportunistic disclosure practices, around significant corporate events, such as the repurchase of their own stock. 相似文献

Summary For the sampling scheme ofMidzuno [3] andSen [4], which provides unbiased ratio estimators an expression for the variance of the estimator does not seem to be available
in literature. An expression for the same is derived in this note. 相似文献

We develop a game-theoretic model to study the timing of new product preannouncement and launch under competition. We derive firms’ optimal timing choices and conducted a numerical analysis to evaluate the role of various factors. Our analytical and numerical results showed that anticipated competitor’s timing choices are the most significant factors. A firm should not preannounce early unless the preannouncement is effective in creating pent-up demands. However, the preannouncement and launch should be rushed if the quality or profit margin of the new product is high, and postponed if the market share of the existing product is high. The market leader should preannounce earlier in a simultaneous game than in a sequential game, but the opposite for the market follower. Data collected from the microprocessor industry validated our model. 相似文献

Critical thinking is a skill that potential employers expect all graduates to possess. Hence, most business management programs consider critical thinking as an important student learning goal. Unfortunately, there is ambiguity about how to best assess critical thinking, both as a skill and a learning outcome. The authors empirically demonstrate how they measure the critical thinking ability of their students in different settings, and how their critical thinking ability improves as they progress through the business program. 相似文献

Objectives: In China, both human urinary kallindinogenase (HUK) and 3-n-butylphthalide (NBP) are recommended for clinical use to improve cerebral blood circulation during an acute ischemic stroke (AIS). The objective was to evaluate the economic value of HUK vs NBP for patients with AIS from a Chinese payer’s perspective.Methods: An economic evaluation based on data of patients who have been treated with either HUK (n?=?488) or NBP (n?=?885) from a prospective, phase IV, multi-center, clinical registry study (Chinese Acute Ischemic Stroke Treatment Outcome Registry, CASTOR) was conducted to analyze the cost and effectiveness of HUK vs NBP for AIS in China. Before the analysis, the patients were matched using propensity score. Both a cost-minimization analysis and a cost-effectiveness analysis were conducted to compare the matched pairs. A bootstrapping exercise was conducted for the matched arms to demonstrate the probability of one intervention being cost-effective over another for a given willingness-to-pay for an extra quality-adjusted life-year (QALY).Results: After propensity score matching, 463 pairs were matched. The overall medical cost in the HUK arm is USD 2,701.20, while the NBP arm is USD 3,436.83, indicating HUK is preferred with cost-minimization analysis. Although the QALY gained in the HUK arm (0.77176) compared with the NBP arm (0.76831) is statistically insignificant (p?=?.4862), the cost-effectiveness analysis as exploratory analysis found that, compared with NBP, HUK is a cost-saving strategy with the lower costs of USD 735.63 and greater QALYs gained of 0.00345. Among the 5,000 bootstrapping replications, 100% indicates that HUK is cost-effective compared with NBP under a 1-time-GDP threshold; and 97.12% indicates the same under a 3-time-GDP threshold.Conclusion: This economic evaluation study indicates that administrating HUK is a cost-saving therapy compared with NBP for managing blood flow during AIS in the Chinese setting. 相似文献

Joint space multidimensional scaling maps are often utilized for positioning analyses and are estimated on survey samples
of consumer preferences, choices, considerations, or intentions so as to provide a concise spatial depiction of the competitive
landscape including relevant dimensions or attributes, competing brands, and consumers in the same joint space representation.
Care has to be given concerning the underlying scale properties of such survey data so as not to distort the resulting joint
space positioning map. We present a new joint space multidimensional scaling procedure for positioning analyses for displaying
the structure in such survey data when such common ordered successive category measurement scales such as Likert, Edwards,
semantic differential, etc., are employed. We present the technical details of this stochastic ordered preference multidimensional
scaling vector model as well as the maximum likelihood estimation-based algorithm devised for parameter estimation. Favorable
comparisons are made with several existent multidimensional scaling methods in representing the internal structure for such
data in marketing positioning studies. An actual commercial positioning application concerning large sports utility vehicles
consideration to buy judgments is presented with predictive validation comparisons with other multidimensional scaling joint
space procedures. 相似文献

We analyze the contents of print ads in the motion picture industry (e.g., number of reviews quoted in the ad, the presence of a top reviewer, size of the ad, star, director, etc.). We find that external validation (a recommendation by a top reviewer) is more important to revenues than the informative content of the ad. 相似文献
