When investors sell one asset and quickly buy another (“reinvestment days”), their trades suggest the original mental account is not closed, but is instead rolled into the new asset. Retail investors trading on their own accounts display a rolled disposition effect, selling the new position when its value exceeds the initial investment in the original position. On reinvestment days, these investors display no disposition effect (consistent with no disutility from realizing a loss) and make better selling decisions. Using a laboratory experiment, we show that reinvestment causally reduces the disposition effect and improves trading.

Foster and Hart (2009) introduce an objective measure of the riskiness of an asset that implies a bound on how much of one’s wealth is ‘safe’ to invest in the asset while (a.s.) guaranteeing no-bankruptcy. In this study, we translate the Foster–Hart measure from static and abstract gambles to dynamic and applied finance using nonparametric estimation of risk-neutral densities from S&P 500 call and put option prices covering 2003–2013. The dynamics of the resulting ‘option-implied Foster–Hart bound’ are assessed in light of other well-known option-implied risk measures including value at risk, expected shortfall and risk-neutral volatility, as well as high moments of the densities and several industry measures. Rigorous variable selection reveals that the new measure is a significant predictor of (large) ahead-return downturns. Furthermore, it grasps more characteristics of the risk-neutral probability distributions in terms of moments than other measures and exhibits predictive consistency. The robustness of the risk-neutral density estimation is analyzed via Monte Carlo methods.

We examine how organizational form affects corporate payouts. Conglomerates pay out more than pure plays in both cash dividends and total payouts (cash dividends plus share repurchases). Furthermore, their payouts are more sensitive to cash flows compared to pure-play firms. The sensitivity of payouts to cash flow increases as the cross-segment correlation in a conglomerate decreases. Corporate payouts increase after mergers and acquisitions (M&As), especially among M&As in which acquirers and targets are less correlated. These results suggest that the coinsurance among different divisions of a conglomerate allows them to pay out more cash flow to their shareholders than pure-play firms.

Before filing suit, a plaintiff can take a financial position in a defendant firm. A short position benefits the plaintiff by transforming a negative expected-value claim into a positive expected-value one and by enhancing the claim's settlement value. If the capital market is less than strong-form efficient, the plaintiff also benefits directly from the decline in the defendant's stock price. When the defendant is privately informed about the case's merits, bargaining failures can arise. While aggressive short-selling benefits the plaintiff at the expense of the defendant, moderate levels of short-selling can benefit the defendant and raise the settlement rate.

Researchers frequently proxy for managers’ non‐GAAP disclosures using performance metrics available through analyst forecast data providers (FDPs), such as I/B/E/S. The extent to which FDP‐provided earnings are a valid proxy for managers’ non‐GAAP reporting, however, has been debated extensively. We explore this important question by creating the first large‐sample data set of managers’ non‐GAAP earnings disclosures, which we directly compare to I/B/E/S data. Although we find a substantial overlap between the two data sets, we also find that they differ in systematic ways because I/B/E/S (1) excludes managers’ lower quality non‐GAAP numbers and (2) sometimes provides higher quality non‐GAAP measures that managers do not explicitly disclose. Our results indicate that using I/B/E/S to identify managers’ non‐GAAP disclosures significantly underestimates the aggressiveness of their reporting choices. We encourage researchers interested in managers’ non‐GAAP reporting to use our newly available data set of manager‐disclosed non‐GAAP metrics because it more accurately captures managers’ reporting choices.

Whistleblowers are ostensibly a valuable resource to regulators investigating securities violations, but whether there is a link between whistleblower involvement and the outcomes of enforcement actions is unclear. Using a data set of employee whistleblowing allegations obtained from the U.S. government and the universe of enforcement actions for financial misrepresentation, we find that whistleblower involvement is associated with higher monetary penalties for targeted firms and employees and with longer prison sentences for culpable executives. We also find that regulators more quickly begin enforcement proceedings when whistleblowers are involved. Our findings suggest that whistleblowers are a valuable source of information for regulators who investigate and prosecute financial misrepresentation.

The size premium has been accused of having a weak historical record, being meager relative to other factors, varying significantly over time, weakening after its discovery, being concentrated among microcap stocks, residing predominantly in January, relying on price-based measures, and being weak internationally. We find, however, that these challenges disappear when controlling for the quality, or its inverse, junk, of a firm. A significant size premium emerges, which is stable through time, robust to specification, not concentrated in microcaps, more consistent across seasons, and evident for non-price-based measures of size, and these results hold in 30 different industries and 24 international equity markets. The resurrected size effect is on par with anomalies such as value and momentum in terms of economic significance and gives rise to new tests of, and challenges for, existing asset pricing theories.

This paper investigates the impacts of defined-benefit (DB) pension plans on the corporate investment choices between diversifying and non-diversifying investments. We find a firm's DB plan coverage is negatively associated with its propensity of making a major investment. Subject to a major investment decision, however, the firms with higher DB plan coverage is more likely to diversify, i.e. acquire firms abroad or in other industries, rather than invest in fixed assets or make non-diversifying (i.e. domestic horizontal) acquisitions. Moreover, in diversifying acquisitions, they are more likely to invest in countries or industries with strongly unionized workforce. Further analysis on post-investment performance shows that firms with higher DB plan coverage experience a greater improvement in operating profitability after a diversifying acquisition, and the improvement mainly comes from a higher asset turnover rather than cost reduction. On the other hand, DB plan sponsoring firms experience a decline in profitability after a large capital expenditure or a non-diversifying acquisition. We propose both bargaining motive and conforming motive can explain these results.

This paper quantitatively assesses time inconsistency, moral hazard, and political ideology in monopoly regulation of electricity distribution. We specify and estimate a dynamic model of utility regulation featuring investment and moral hazard. We find underinvestment in electricity distribution capital aiming to reduce power outages and use the estimated model to quantify the value of regulatory commitment in inducing greater investment. Furthermore, more conservative political environments grant higher regulated returns but have higher rates of electricity loss. Using the estimated model, we quantify how conservative regulators thus mitigate welfare losses due to time inconsistency but worsen losses from moral hazard.
