Why do stock repurchases change over time?

Recent studies have shown the time trends of firm stock repurchase behavior. We examine these time changes for stock repurchase through the lens of real activities earnings management. Managers appear more likely to manipulate earnings through stock repurchases since the passage of the Sarbanes–Oxley Act (SOX) in 2002. Furthermore, suspect firms that just missed analyst earnings per share forecasts have higher incentives to manipulate earnings through stock repurchases. The results are not driven by changes in corporate governance associated with the passage of SOX. Overall, our results suggest earnings management can be a significant determinant of the dynamics of stock repurchases.     

Is there Causal Relationship between Money Supply Growth and Inflation in China? Evidence from Quantity Theory of Money

This study examines the causal relationship between Chinese money supply growth and inflation, using the bootstrap Granger full‐sample causality test and sub‐sample rolling‐window estimation test to determine whether such a relationship in China supports the quantity theory of money. The result indicates that there is a unidirectional relationship from inflation to money supply growth. However, considering structural changes in two series, we find that short‐run relationships using full‐sample data are unstable, which suggests that full‐sample causality tests cannot be relied upon. Then, we use a time‐varying rolling‐window approach to revisit the dynamic causal relationship, and the results show that money supply growth has both positive and negative impacts on inflation in several sub‐periods, and in turn, inflation has the same effects on money supply growth for China. These findings are basically consistent with the modern quantity theory of money from the perspective of money supply and price level. When money supply growth does not outweigh output growth, inflation should not be curbed only by decreasing money supply. It notes that a stable money supply growth is critical to price level stability and economic development in China.     

The Optimal Timing of Open Market Stock Repurchases

Using a continuous-time real options approach we determine the conditions under which a value-maximizing company would conduct an open market stock repurchase to exploit the undervaluation of shares. We find the optimal timing of such repurchases as well as the optimal amount a company should repurchase and analyze how it depends on market parameters. Obtaining the announcement returns from the authorization of stock repurchases from our model allows us to derive testable empirical implications.     

The overconfidence of investors in the primary market

We analyze the investment performance of 6993 investors bidding in 77 discriminatory IPO auctions in the Taiwan stock market between January 1996 and April 2000, and find that frequent bidders in these auctions have lower returns than infrequent bidders. The frequent bidders bid too aggressively and evaluate the IPO firms too optimistically, resulting in inferior performance. Despite being quite successful in their first few auction bids, the returns for frequent investors are gradually reduced in subsequent auctions. The multivariate model and the analysis of the possibility of perverse incentives of brokerage firms suggest that our findings cannot be explained by rational hypotheses, whereas in contrast, the theories on overconfidence and self-attribution bias can explain the increase in bidding frequency and the deterioration in return performance for bidders in IPO auctions.     

Entry mode choice in China's regional distribution markets: Institution vs. transaction costs perspectives

In this paper, we investigate the entry mode choice of a leading Taiwanese food company in setting up regional distributors in China's 312 sales districts. Our study shows that, in entry mode decisions, the institutional factors are more important than transaction cost considerations. Both formal and informal institutions are considered. Formal institutions refer to government prescribed institutions (laws and regulations), while informal institutions refer to rules prescribed by the industry and the society. Both institutions are shown to affect the entry mode choices but one important type of institution, professional norms, is conspicuously missing in China. Professional norms exert peer pressures on the practitioners in the same profession, forcing their behaviors to conform to a common pattern. In the absence of professional norms, the roles of network ties and mimetic behaviors are heightened and they become a proxy for professional norms. As a foreign enterprise operating in China's local markets, the Taiwanese food company attained legitimacy by forming alliances with local wholesalers and by following its predecessors in selecting organization forms.     

贸易财属性与贸易政策竞争均衡

本文利用两国两异质财货的产业内贸易模型,讨论贸易财属性与贸易政策竞争均衡的决定,并获得以下结论:(1)当两国政府均采取相同的进口或出口政策时,不论产品的消费性质,最适进口贸易政策均为课税;最适出口贸易政策将随贸易财的消费性质而定.替代品为出口补贴,互补品为出口课税.(2)当产品为替代品且厂商在两国市场均实行数量竞争的情况下,进口课税政策虽将成为两国政府的优势策略,但出口补贴政策则更具有效率.在产品为互补品且厂商在两国市场均实行价格竞争的情况下,当产品的互补程度较小(大)时,进口课税(出口课税)政策将成为两国政府的优势策略;当互补程度中等时,两国政府有可能采取差异性的贸易政策.     

Health insurance and precautionary saving: A structural analysis

Starr-McCluer (1996) documented an empirical finding showing that US households covered by health insurance saved more than those without coverage, which is inconsistent with the standard consumption–saving theory. This study conducts a structural analysis and suggests that institutional factors, particularly, a social insurance or safety net system and an employment-based health insurance system, can account for this puzzling finding. A dynamic equilibrium model is built that combines these two institutions with heterogeneous agents making endogenous decisions regarding saving, the labor supply and health insurance when they are young. The model, in which agents save in a precautionary manner, can generate Starr-McCluer?s empirical finding. The result implies that Starr-McCluer?s results are not inconsistent with the standard theory of saving under uncertainty, but it does indicate that the standard saving regression model is unable to reveal the precautionary saving motive. Counterfactual experiments are performed to provide implications for empirical analyses.     

Tax Auditing as a Public Good Game: An Experimental Study on Punishment and Compliance

Prior experimental studies on tax evasion generally assume that the budget and the probability of audit are exogenously given, and ignore taxpayers' incentives to detect evasion and their compliance behaviour under such incentives. The experimental evidence of the present paper shows that, on average, subjects are willing to spend 20 to 30% of their tax revenue on auditing. Compliance is also greatly improved if subjects can determine the budget and, hence, the probability of audit. These findings suggest that taking taxpayers' incentives to detect evasion into consideration is important for the design of compliance‐improvement audit schemes.     

Native American casino marketing on the web

The Internet and its component, the World Wide Web (WWW or Web), as well as the casino industry grew tremendously in the United States in the past decade. While there are various estimates about the future size of the Internet and the casino market, all agree that the two will continue to grow substantially. However, very few studies have discussed Internet use within the casino industry. This study reviewed 58 Class III Native American casino web sites. Content areas analyzed included introduction to the casino organization, local destination attractions, food and beverage services, accommodations, entertainment and recreation facilities, maps and directions to casinos, links to related commercial and regulatory agency web sites, and user friendliness. Web site features were evaluated based on marketing mix and principles.
