ABSTRACT We document widespread changes to the historical I/B/E/S analyst stock recommendations database. Across seven I/B/E/S downloads, obtained between 2000 and 2007, we find that between 6,580 (1.6%) and 97,582 (21.7%) of matched observations are different from one download to the next. The changes include alterations of recommendations, additions and deletions of records, and removal of analyst names. These changes are nonrandom, clustering by analyst reputation, broker size and status, and recommendation boldness, and affect trading signal classifications and back‐tests of three stylized facts: profitability of trading signals, profitability of consensus recommendation changes, and persistence in individual analyst stock‐picking ability.

ABSTRACT This study shows that the propensity to gamble and investment decisions are correlated. At the aggregate level, individual investors prefer stocks with lottery features, and like lottery demand, the demand for lottery‐type stocks increases during economic downturns. In the cross‐section, socioeconomic factors that induce greater expenditure in lotteries are associated with greater investment in lottery‐type stocks. Further, lottery investment levels are higher in regions with favorable lottery environments. Because lottery‐type stocks underperform, gambling‐related underperformance is greater among low‐income investors who excessively overweight lottery‐type stocks. These results indicate that state lotteries and lottery‐type stocks attract very similar socioeconomic clienteles.

ABSTRACT We show that the parent‐subsidiary structure of multinational firms created by cross‐border mergers and acquisitions is affected by the prospect of international double taxation. Specifically, the likelihood of parent firm location in a country following a cross‐border takeover is reduced by high international double taxation of foreign‐source income. At the same time, countries with high international double taxation attract smaller numbers of parent firms. A unilateral elimination of worldwide taxation by the United States is simulated to increase the proportion of parent firms locating in the United States following cross‐border mergers and acquisitions from 53% to 58%.

ABSTRACT We report evidence on the determinants of whether the relationship between a firm and its Chief Executive Officer (CEO) is governed by an explicit (written) or an implicit agreement. We find that fewer than half of the CEOs of S&P 500 firms have comprehensive explicit employment agreements. Consistent with contracting theory, explicit agreements are more likely to be observed and are likely to have a longer duration in situations in which the sustainability of the relationship is less certain and where the expected loss to the CEO is greater if the firm fails to honor the agreement.

ABSTRACT Accurate appraisal of hedge fund performance must recognize the freedom with which managers shift asset classes, strategies, and leverage in response to changing market conditions and arbitrage opportunities. The standard measure of performance is the abnormal return defined by a hedge fund's exposure to risk factors. If exposures are assumed constant when, in fact, they vary through time, estimated abnormal returns may be incorrect. We employ an optimal changepoint regression that allows risk exposures to shift, and illustrate the impact on performance appraisal using a sample of live and dead funds during the period January 1994 through December 2005.

ABSTRACT We propose and test a catering theory of nominal stock prices. The theory predicts that when investors place higher valuations on low‐price firms, managers respond by supplying shares at lower price levels, and vice versa. We confirm these predictions in time‐series and firm‐level data using several measures of time‐varying catering incentives. More generally, the results provide unusually clean evidence that catering influences corporate decisions, because the process of targeting nominal share prices is not well explained by alternative theories.

ABSTRACT Business connections can mitigate agency conflicts by facilitating efficient information transfers, but can also be channels for inefficient favoritism. I analyze these two effects in the mutual fund industry and find that fund directors and advisory firms that manage the funds hire each other preferentially based on the intensity of their past interactions. I do not find evidence that stronger board‐advisor ties correspond to better or worse outcomes for fund shareholders. These results suggest that the two effects of board‐management connections on investor welfare—improved monitoring and increased potential for collusion—balance out in this setting.

ABSTRACT The notion that firms have a debt ratio target that is a primary determinant of financing behavior is influential in finance. Yet, how definitive is the evidence? We address this issue by generating samples where financing is unrelated to a firm's current debt ratio or a target. We find that much of the available evidence in favor of target behavior based on leverage ratio changes can be reproduced for these samples. Taken together, our findings suggest that a number of existing tests of target behavior have no power to reject alternatives.

ABSTRACT Private equity funds are important to the economy, yet there is little analysis explaining their financial structure. In our model the financial structure minimizes agency conflicts between fund managers and investors. Relative to financing each deal separately, raising a fund where the manager receives a fraction of aggregate excess returns reduces incentives to make bad investments. Efficiency is further improved by requiring funds to also use deal‐by‐deal debt financing, which becomes unavailable in states where internal discipline fails. Private equity investment becomes highly sensitive to aggregate credit conditions and investments in bad states outperform investments in good states.

ABSTRACT We develop a framework for estimating expected returns—a predictive system —that allows predictors to be imperfectly correlated with the conditional expected return. When predictors are imperfect, the estimated expected return depends on past returns in a manner that hinges on the correlation between unexpected returns and innovations in expected returns. We find empirically that prior beliefs about this correlation, which is most likely negative, substantially affect estimates of expected returns as well as various inferences about predictability, including assessments of a predictor's usefulness. Compared to standard predictive regressions, predictive systems deliver different expected returns with higher estimated precision.
