Exploiting the fact that insiders trade for a variety of reasons, we show that there is predictable, identifiable “routine” insider trading that is not informative about firms’ futures. A portfolio strategy that focuses solely on the remaining “opportunistic” traders yields value‐weighted abnormal returns of 82 basis points per month, while abnormal returns associated with routine traders are essentially zero. The most informed opportunistic traders are local, nonexecutive insiders from geographically concentrated, poorly governed firms. Opportunistic traders are significantly more likely to have SEC enforcement action taken against them, and reduce trading following waves of SEC insider trading enforcement.

Public policy discussions typically favor greater corporate disclosure as a way to reduce firms' agency problems. This argument is incomplete because it overlooks that better disclosure regimes can also aggravate agency problems and related costs, including executive compensation. Consequently, a point can exist beyond which additional disclosure decreases firm value. Holding all else equal, we further show that larger firms will adopt stricter disclosure rules than smaller firms and firms with better disclosure will employ more able management. We show that mandated increases in disclosure could, in part, explain recent increases in both CEO compensation and CEO turnover rates.

We provide new evidence on the role of financial advisors in M&As. Contrary to prior studies, top‐tier advisors deliver higher bidder returns than their non‐top‐tier counterparts but in public acquisitions only, where the advisor reputational exposure and required skills set are relatively larger. This translates into a $65.83 million shareholder gain for an average bidder. The improvement comes from top‐tier advisors' ability to identify more synergistic combinations and to get a larger share of synergies to accrue to bidders. Consistent with the premium price–premium quality equilibrium, top‐tier advisors charge premium fees in these transactions.

This paper explores the economic role credit rating agencies play in the corporate bond market. We consider three existing theories about multiple ratings: information production, rating shopping, and regulatory certification. Using differences in rating composition, default prediction, and credit spread changes, our evidence only supports regulatory certification. Marginal, additional credit ratings are more likely to occur because of, and seem to matter primarily for, regulatory purposes. They do not seem to provide significant additional information related to credit quality.

To produce significant net present value, an entrepreneur has to differentiate her enterprise from the ordinary. To take collaborators with her, she needs to have substantial ownership, and thus financing. But it is hard to raise finance against differentiated assets. So an entrepreneur has to commit to undertake a second transformation, standardization, that will make the human capital in the firm, including her own, replaceable, so that outside financiers obtain control rights that will allow them to be repaid. A vibrant stock market helps the entrepreneur commit to these two transformations. The nature of firms and financing are intimately linked.

This paper uses novel data to examine the fleets of corporate jets operated by both publicly traded and privately held firms. In the cross‐section, firms owned by private equity funds average 40% smaller fleets than observably similar public firms. Similar fleet reductions are observed within firms that undergo leveraged buyouts. Quantile regressions indicate that these results are driven by firms in the upper 30% of the conditional jet distribution. The results thus suggest that executives in a substantial minority of public firms enjoy excessive perquisite and compensation packages.

I examine how media coverage of good and bad corporate news affects stock prices, by studying the effect of investor relations (IR) firms. I find that IR firms “spin” their clients' news, generating more media coverage of positive press releases than negative press releases. This spin increases announcement returns. Around earnings announcements, however, IR firms cannot spin the news and their clients' returns are significantly lower. This pattern is consistent with positive media coverage increasing investor expectations, creating disappointment around hard information. Using reporter connections and geographical links, I argue that IR firms causally affect both media coverage and returns.

Are some banks prone to perform poorly during crises? If yes, why? In this paper, we show that a bank's stock return performance during the 1998 crisis predicts its stock return performance and probability of failure during the recent financial crisis. This effect is economically large. Our findings are consistent with persistence in a bank's risk culture and/or aspects of its business model that make its performance sensitive to crises. Banks that relied more on short‐term funding, had more leverage, and grew more are more likely to be banks that performed poorly in both crises.

Mutual funds are held by investors in taxable and tax‐qualified retirement accounts. We investigate whether the characteristics, investment strategies, and performance of mutual funds held by these diverse tax clienteles differ. Examining both mutual fund distributions and mutual fund holdings, we find that funds held primarily by taxable investors choose investment strategies that result in lower tax burdens than funds held primarily in tax‐qualified accounts. Despite these differences, we find no evidence that any investment constraints that may arise from these tax‐efficient investment strategies result in performance differences between funds held by different tax clienteles.

According to conventional wisdom, annualized volatility of stock returns is lower over long horizons than over short horizons, due to mean reversion induced by return predictability. In contrast, we find that stocks are substantially more volatile over long horizons from an investor's perspective. This perspective recognizes that parameters are uncertain, even with two centuries of data, and that observable predictors imperfectly deliver the conditional expected return. Mean reversion contributes strongly to reducing long‐horizon variance but is more than offset by various uncertainties faced by the investor. The same uncertainties reduce desired stock allocations of long‐horizon investors contemplating target‐date funds.
