We characterize the set of communication equilibrium payoffs of any undiscounted repeated matrix-game with imperfect monitoring and complete information. For two-player games, a characterization is provided by Mertens, Sorin, and Zamir (Repeated games, Part A (1994) CORE DP 9420), mainly using Lehrer's (Math. Operations Res. (1992) 175) result for correlated equilibria. The main result of this paper is to extend this characterization to the n-player case. The proof of the characterization relies on an analogy with an auxiliary 2-player repeated game with incomplete information and imperfect monitoring. We use Kohlberg's (Int. J. Game Theory (1975) 7) result to construct explicitly a canonical communication device for each communication equilibrium payoff. 相似文献

Previous studies document that forecast accuracy impacts analyst career outcomes. This paper investigates the influence of forecast accuracy on coverage assignments. I show that brokerage houses reward accurate analysts by assigning them to high-profile firms and penalise analysts exhibiting poor accuracy by assigning them to smaller firms. The coverage of high-profile firms increases the potential for future compensation linked to investment banking and trading commissions. In addition, covering such firms increases analysts' recognition from buy-side investors, which, in turn, increases the likelihood of obtaining broker votes and votes for the Institutional Investor star ranking. Overall, my results indicate that high forecast accuracy leads to increased future compensation. 相似文献

This study surveys the empirical literature in which the gravity equation has been used to study the effect of economic integration agreements (EIAs) on international trade flows. We show that most studies either focus on improving the methodology to assess regionalism’s overall impact, or on a small set of well-known agreements without necessarily adopting new methodological improvements. We bridge this gap by providing individual estimates for EIAs on world trade, while employing first-differencing techniques to correct for endogeneity bias and account for phase-in effects. Overall, EIAs promote trade by at most 50 %. Surprisingly, more than half of the EIAs investigated have had no discernible impact on trade at all, while only about one quarter of the agreements are trade promoting. Characteristics of these agreements, such as their institutional quality, design, and their members’ involvement in the World Trade Organisation, shed more light on how this variation can be understood. 相似文献

The 1997 Economic Census data on minority and women-owned businesses reveals distinct cross-state and cross-county differences in ownership characteristics. The breakdown of this data into racial groups provides the opportunity to study the geographical features of black enterprise. As will be seen, both in aggregate and across states and counties, significant differences exist in the prevalence and magnitude of black and white enterprise. I propose a "legacy of slavery" hypothesis to explain these observed differences. Preliminary analysis indicates that this hypothesis has considerable explanatory power. A significant negative relationship exists between the geographical concentration of slavery in 1840 and the current prevalence and magnitude of black-owned enterprise. At the state level, this relationship remains even after controlling for the normal business climate as indicated by white enterprise levels. County level regressions with state fixed-effects yield similar estimated coefficients. In total, I find that the legacy of slavery has reduced the number of black-owned businesses by at least 71,009 and sales by $27.3 billion per year. 相似文献

Employee stock options (ESOs) are a popular way of remunerating employees. We analyse factors at the firm and option level affecting the employee's decision to exercise ESOs before they mature. Exercises over the period 1998–2004 are analysed and the key factor influencing early exercise is found to be dividends. Exercises frequently occur well before maturity, but in most cases little time value is sacrificed. Our findings have implications for the ‘fair’ valuation of ESOs in companies’ financial statements, as required by the relevant Australian accounting standard, AASB 2. 相似文献

How can the pension schemes be sustainably financed? This is an important issue particularly with regard to the demographic changes in many industrialized countries but also in other emerging economies such as China and India. In this paper, we use a macroeconomic model of overlapping generations to analyze the impacts of the demographic changes as well as the interactions between pension system, bond and stock markets. Furthermore, we examine how the pension system influences the distribution of wealth, consumption and saving within generations. We found out that an aging population will cause a drastic decline. Moreover, we examined which impacts on individuals?? welfare demographic changes can have for an existing pay-as-you-go pension scheme. An increase of pension age combined with a decrease of the contributions seems to be the best policy. On the other hand, increases in contributions as a result of demographic changes show the highest welfare losses. 相似文献

AbstractThis article examines contemporary French retail history, studying both transformations in retail structures and evolutions in government retail policies from 1945 to 1973. It notably questions the existence of a defined public policy for the retail sector. Based on extensive archival research, it is designed to offer an overview of the topic in order to familiarise international scholars with French retail history, while stimulating discussion and providing case material to enable comparisons with other national cases. 相似文献
