Price Momentum and Idiosyncratic Volatility

We find that returns to momentum investing are higher among high idiosyncratic volatility (IVol) stocks, especially high IVol losers. Higher IVol stocks also experience quicker and larger reversals. The findings are consistent with momentum profits being attributable to underreaction to firm-specific information and with IVol limiting arbitrage of the momentum effect. We also find a positive time-series relation between momentum returns and aggregate IVol. Given the long-term rise in IVol, this result helps explain the persistence of momentum profits since Jegadeesh and Titmans (1993) study.

It Takes Two: The Incidence and Effectiveness of Co‐CEOs

This study examines the phenomenon of co‐CEOs within publicly traded firms. Although shared executive leadership is not widespread, it occurs within some very prominent firms. We find that co‐CEOs generally complement each other in terms of educational background or executive responsibilities. Our results show that firms most likely to appoint co‐CEOs have lower leverage, a more limited firm focus, less independent board structure, fewer advising directors, lower institutional ownership, and greater levels of merger activity. The governance structure of co‐CEO firms suggests that co‐CEOships can serve as an alternative governance mechanism, with co‐CEO mutual monitoring substituting for board or external monitoring and co‐CEO complementary skills substituting for board advising. An event study indicates that the market reacts positively to appointments of co‐CEOs while a propensity score analysis shows that the presence of co‐CEOs increases firm valuation.

Territorial Tax System Reform and Corporate Financial Policies

We examine the effect of a permanent change to a country corporate income repatriation tax system on corporate financial policies. In 2009, Japan and the United Kingdom switched from a worldwide system to a territorial system for the taxation of repatriated foreign earnings, effectively reducing the tax liabilities of most multinational firms when repatriating earnings. We find that after the change firms accumulate less cash, pay out larger amounts through dividends and share repurchases, and invest less abroad. We do not find that the tax system change has significantly affected domestic investments even when controlling for capital constraints.

A survey of litigation in corporate finance

Purpose The purpose of this paper is to review research on litigation in corporate finance. Design/methodology/approach This paper surveys studies on the estimation of litigation risk, litigation costs, stock reaction to lawsuit announcement, and the effect of litigation on corporate financial policies and outcomes. Findings The first section presents a survey of studies that estimate litigation risk. The authors then discuss a set of studies that focus on the various costs associated with litigation. The third area of review is about studies which estimate the market reaction to a lawsuit announcement. The next section surveys studies that examine the relation between litigation and a variety of corporate policies, behaviors, and outcomes. The authors then discuss the emerging literature on how corporate political connections can influence the outcome of litigation. The survey concludes with a brief summary and a discussion of suggestions for future research involving corporate litigation. Originality/value By providing an extensive review of the literature on litigation in corporate finance, this survey can help researchers to identify recent trends in litigation research and select promising new avenues of investigation in the field.

Investment Bank Expertise in Cross-Border Mergers and Acquisitions

We study the influence of country expertise of investment banks in facilitating cross-border merger deals by analyzing a large international sample of M&A deals. We provide evidence that the geographical proximity, cultural affinity, and local experience of investment banks advising bidding firms on cross-border M&A deals significantly decrease the time to completion required to complete the deal, significantly increase the probability of completion of the deal and the operating performance of the acquiring firm after the deal. The cultural affinity between the bank and the target country and the expertise of the acquirer on the target country have also a significant positive effect on the stock market reaction at the announcement of the deal. Our results are robust to firm, deal, country specific factors, and endogeneity concerns.

A Face Can Launch a Thousand Shares (and a 0.80% Abnormal Return)

In this paper we examine the market reaction—price and volume—to the appearance of a firm in the Whos News column of The Wall Street Journal. We differentiate between those firms whose articles are accompanied by a picture of an executive and a control set of firms whose articles on the same day are not accompanied by a picture. The results show a more pronounced market reaction to the “cum picture” articles, consistent with the incomplete information theory of Merton [1987] and the heuristic-based familiarity hypothesis. There is no evidence of significant long-run abnormal performance for the sample firms.
