Managers' Trading Around Stock Repurchases

We analyze personal open market trades by managers around stock repurchases by tender offer. With the exception of Dutch auction offers, managers trade their firm's shares prior to repurchase announcements as though repurchases convey favorable inside information to outsiders. Prior to fixed price repurchase offers that do not follow takeover-related events, managers increase their buying and reduce their selling of their firm's shares. Prior to repurchases that follow takeover-related events, only a decrease in selling is found. No abnormal trading precedes Dutch auction repurchase offers.     

Sovereign Credit Risk,Banks' Government Support,and Bank Stock Returns around the World

We explore the joint effect of expected government support to banks and changes in sovereign credit ratings on bank stock returns using data for banks in 37 countries between 1995 and 2011. We find that sovereign credit rating downgrades have a large negative effect on bank stock returns for those banks that are expected to receive stronger support from their governments. This result is stronger for banks in advanced economies where governments are better positioned to provide that support. Our results suggest that stock market investors perceive sovereigns and domestic banks as markedly interconnected, partly through government guarantees.     

The audit expectation gap： A review of the contributing factors

The audit expectation gap is critical to the auditing profession because the greater the unfulfilled expectations from the public, the lower is the credibility, earning potential and prestige associated with the work of auditors. The aim of this paper is to uncover the causes of an audit expectation gap. It is revealed that the existence of an audit expectation gap is due to complicated nature of an audit function; conflicting role of auditors; retrospective evaluation of auditors＇ performance; time lag in responding to changing expectation; and self-regulation process of the auditing profession.     

WHY ARE AMERICANS ADDICTED TO BASEBALL? AN EMPIRICAL ANALYSIS OF FANDOM IN KOREA AND THE UNITED STATES

Theories of rational addiction posit that certain habit-forming goods—characterized by an increasing marginal utility of consumption—generate predictable dynamic patterns of consumer behavior. It has been suggested that attendance at sporting events represents an example of such a good, as evidenced by the pricing strategies of commercial sports interests. In this essay, we provide new evidence in support of rational addiction for the case of Major League Baseball but fail to find such support in data from the Korean Professional Baseball League. We then review the scientific literature on sports fans from the perspective of human behavioral ecology and propose a theory of endogenous habit formation among sports fans that could explain our findings .

DURABLE GOODS MONOPOLISTS AND BACKWARD COMPATIBILITY*

This paper provides an economic analysis on the choice of backward compatibility by a durable goods monopolist in the presence of network effects. We examine the time inconsistency problem faced by a monopolist in its dynamic provision of two compatible products. We suggest an economic reason why, and when it will be strategically optimal, for the monopolist to choose backward compatibility even though it is socially undesirable, and not to choose forward compatibility even though it is technologically possible. We also investigate the compatibility choices with and without price discrimination, and compare market outcomes with the social optimum. Two different social inefficiencies (planned obsolescence) which arise from the viewpoints of optimal consumption and optimal compatibility are discussed.     

HOW THE GLOBALIZATION OF R&D COMPETITION AFFECTS TRADE AND GROWTH

The implications of international R&D competition on trade and growth are investigated. The model is one in which a separate R&D sector competes with the manufacturing sector to secure human capital, and technology is licensed to manufacturers by the winner of a pre-emptive R&D competition. The results show that globalization of R&D competition leads to trade between countries (even identical countries), because the result of competition leads to a reallocation of human capital between sectors. The winning country exports technology and traditional goods, while the loser exports manufactured goods. Globalization with indiscriminate technology licensing increases the world's economic growth rate.
