Abstract During 2004 and 2005, long-horizon interest rates fell sharply in major international government bond markets (Greenspan's “conundrum”). This common fall mainly reflected lower long real rates. To investigate possible causes, the authors apply a no-arbitrage affine modeling framework to understanding the UK real term structure. The authors find that time-varying term premia are important in explaining movements in long real forward rates. And, although there is evidence that long-horizon expected short real rates declined over the conundrum period, the authors’ results suggest that lower term premia played the dominant role. This could be consistent with the so-called “search for yield” and excess liquidity explanations for the conundrum.

This paper examines the evolution of corporate boards following a large performance decline. Over 40% of the original directors depart the board during the three years following underperformance. Measures of initial CEO influence over the board such as CEO ownership are associated with smaller increases in board independence and less board turnover. The underperforming firms undergo a strong recovery subsequently, with the largest performance improvement occurring among firms that experience no turnover on their boards and among firms that do not change their board independence. We conclude that the large board turnover experienced by underperforming firms presents significant challenges for subsequent recovery.
Abstract This paper shows that a New Year's gambling preference of individual investors impacts prices and returns of assets with lottery features. January call options, especially the out-of-the-money calls, have higher retail demand and are the most expensive and actively traded. Lottery-type stocks outperform their counterparts in January but tend to underperform in other months. Retail sentiment is more bullish in lottery-type stocks in January than in other months. Furthermore, lottery-type Chinese stocks outperform in the Chinese New Year's Month but not in January. This New Year effect provides new insights into the broad phenomena related to the January effect.

ABSTRACT We find that lower ex ante earnings volatility leads to higher Post–Earnings Announcement Drift (PEAD). PEAD is a function of both the magnitude of an earnings surprise and its persistence. While prior research has largely investigated market reactions to the magnitude of the earnings surprise, in this study we show that the persistence of the earnings surprise is equally important. A unique feature of the anomalous PEAD returns documented here concerns the association between abnormal returns and trading frictions. Besides demonstrating that firms with lower earnings volatility have higher abnormal returns, we also find that lower earnings volatility firms have lower trading frictions. Taken together, these findings imply that higher abnormal returns are associated with lower trading frictions. We exploit this implication to empirically demonstrate that PEAD returns due to earnings volatility are not concentrated in the firms with the largest trading frictions, which is in contrast to the findings in prior anomaly studies.

We examine the relation between corporate governance and firms' information environments. We use the passage of state antitakeover laws in the U.S. as a source of exogenous variation in an important governance mechanism to identify changes in firms' information environments. We find that information asymmetry and private information gathering decreased and that financial statement informativeness increased following the passage of the antitakeover laws. Cross-sectional analyses indicate that the increased level of financial statement informativeness is attributable to firms that are most likely to access equity markets rather than managerial entrenchment, managerial career concerns, or managers' pursuit of the quiet life.

We use a proprietary data set with detailed executive compensation information to examine the relationship between the incentives of the tax director and GAAP and cash effective tax rates, the book-tax gap, and measures of tax aggressiveness. We find that the incentive compensation of the tax director exhibits a strong negative relationship with the GAAP effective tax rate, but little relationship with the other tax attributes. We interpret these results as indicating that tax directors are provided with incentives to reduce the level of tax expense reported in the financial statements.
We examine the structure of communications in accounting research by analyzing patterns of citations among authors who have published in five major journals between 1984 and 2008. Understanding communication structures is important because they shape academic knowledge creation, which prominent scholars have claimed has become narrowly focused and self-perpetuating in accounting due to a specific type of communication structure - 'tribalism.' We use a mathematical algorithm and other analyses to distinguish among five types of communication structures. We find that the field contains multiple clusters, with some clusters being centered on research topics alone, a finding consistent with a 'normal academic field.' Remaining clusters are more narrowly based – on combinations of topics, methods and theory bases – and all but one of them represent a “small world” structure because they are close together and exhibit frequent communication. Both normal academic fields and small worlds have been shown to contribute positively to innovation in research. The economics-based archival financial accounting cluster exhibits some properties of a tribal structure because, while researchers in other clusters communicate toward this cluster, the cluster sends most of its outbound communication to itself. A contribution of our study is that it shows that tribalism is not as rampant as previously suggested. Also, our findings suggest the field has become less tribal over time. Further, we identify 'hub' researchers who attract communications from multiple clusters and whose articles build on, and cite, work from multiple clusters. These individuals are instrumental in moving fields away from tribalism. Finally, we discuss possible determinants and consequences of the existing communication structure.

We study efficient non-linear taxation of labour and capital in a dynamic Mirrleesian model incorporating political economy constraints. Policies are chosen sequentially over time, without commitment. Our main result is that the marginal tax on capital income is progressive, in the sense that richer agents face higher marginal tax rates.

The sensitivity of stock options' payoff to return volatility, or vega, provides risk-averse CEOs with an incentive to increase their firms' risk more by increasing systematic rather than idiosyncratic risk. This effect manifests because any increase in the firm's systematic risk can be hedged by a CEO who can trade the market portfolio. Consistent with this prediction, we find that vega gives CEOs incentives to increase their firms' total risk by increasing systematic risk but not idiosyncratic risk. Collectively, our results suggest that stock options might not always encourage managers to pursue projects that are primarily characterized by idiosyncratic risk when projects with systematic risk are available as an alternative.
