  1. Golden Parachutes and the Wealth of Shareholders

    Golden parachutes (GPs) have attracted substantial attention from investors and public officials for more than two decades. We find that GPs are associated with higher expected acquisition premiums and that this association is at least partly due to the effect of GPs on executive incentives. However, we also find that firms that adopt GPs experience negative abnormal stock returns both during and subsequent to the period surrounding their adoption. This finding raises the possibility that even though GPs facilitate some value-increasing acquisitions, they do have, on average, an overall negative effect on shareholder wealth; this effect could be due to GPs weakening the force of the market for control and thereby increasing managerial slack, and/or to GPs making it attractive for executives to go along with some value-decreasing acquisitions that do not serve shareholders' long-term interests. Our findings have significant implications for ongoing debates on GPs and suggest the need for additional work identifying the types of GPs that drive the identified correlation between GPs and reduced shareholder value.

  2. How Do Staggered Boards Affect Shareholder Value? Evidence from a Natural Experiment

    The well-established negative correlation between staggered boards (SBs) and firm value could be due to SBs leading to lower value or a reflection of low-value firms' greater propensity to maintain SBs. We analyze the causal question using a natural experiment involving two Delaware court rulings―separated by several weeks and going in opposite directions―that affected the antitakeover force of SBs. We contribute to the long-standing debate on staggered boards by documenting empirical evidence consistent with the market viewing SBs as leading to lower firm value for the affected firms.

  3. Boardroom Centrality and Firm Performance

    Firms with central or well-connected boards of directors earn superior risk-adjusted stock returns. Initiating a long position in the most central firms and a short position in the least central firms earns an average risk-adjusted return of 4.68% per year. Firms with central boards also experience higher future growth in return-on-assets (ROA) with analysts failing to fully reflect this information in their earnings forecasts. Return prediction, growth in ROA, and analyst forecast errors are concentrated among firms with high growth opportunities or firms confronting adverse circumstances, consistent with boardroom connections mattering most for firms that stand to benefit most from the information communicated and resources exchanged through the network of board members. Overall, our results suggest that board of director networks provide economic benefits that are not immediately reflected in stock prices.

  4. Learning and the Disappearing Association Between Governance and Returns

    The correlation between governance indices and abnormal returns documented for 1990–1999 subsequently disappeared. The correlation and its disappearance are both due to market participants' gradually learning to appreciate the difference between good-governance and poor-governance firms. Consistent with learning, the correlation's disappearance was associated with increases in market participants' attention to governance; market participants and security analysts were, until the beginning of the 2000s but not subsequently, more positively surprised by the earning announcements of good-governance firms; and, although governance indices no longer generated abnormal returns during the 2000s, their negative association with firm value and operating performance persisted.

Working Papers

  1. Measurement Errors of Expected Returns Proxies and the Implied Cost of Capital

    This paper presents a methodology to study implied cost of capital's (ICC) measurement errors, which are relatively unstudied empirically despite ICCs' popularity as proxies of expected returns. By applying it to the popular implementation of ICCs of Gebhardt, Lee, and Swaminathan (2001)(GLS), I show that the methodology is useful for explaining the variation in GLS measurement errors. I document the first direct empirical evidence that ICC measurement errors can be persistent, can be associated with firms' risk or growth characteristics, and thus confound regression inferences on expected returns. I also show that GLS measurement errors and the spurious correlations they produce are driven not only by analysts' systematic forecast errors but also by functional form assumptions. This finding suggests that correcting for the former alone is unlikely to fully resolve these measurement-error issues. To make robust inferences on expected returns, ICC regressions should be complemented by realized-returns regressions.

  2. Expected Returns Dynamics Implied by Firm Fundamentals

    We provide a tractable stock valuation model to study the dynamics of firm-level expected returns and their valuation impact using two firm fundamentals: book-to-market ratio and ROE. Applying the model to the cross-section of firms, we find that expected returns and expected profitability are highly persistent and time-varying. Our fundamentals-implied estimates of expected returns across time horizons exhibit strong return predictability up to three years ahead, and produce an aggregate equity term structure that tracks economic conditions. The implied term structure is upward sloping during normal or expansion periods, but flattens or inverts during economic downturns or times of high uncertainty. Finally, we show that ignoring the dynamics of expected returns can produce large valuation errors.

  3. Search Based Peer Firms: Aggregating Investor Perceptions Through Internet Co-Searches

    Applying a "co-search" algorithm to Internet traffic at the SEC's EDGAR website, we develop a novel method for identifying economically related peer firms. Our results show that firms appearing in chronologically adjacent searches by the same individual (Search Based Peers or SBPs) are fundamentally similar on multiple dimensions. In direct tests, SBPs dominate GICS6 industry peers in explaining cross-sectional variations in base firms' out-of-sample (a) stock returns, (b) valuation multiples, (c) growth rates, (d) R&D expenditures, (e) leverage, and (f) profitability ratios. We show that SBPs are not constrained by standard industry classification and are more dynamic, pliable, and concentrated. Our results highlight the potential of the collective wisdom of investors―extracted from co-search patterns―in addressing long-standing benchmarking problems in finance.

  4. Can Implicit Regulation Change Financial Market Behavior? Evidence from Spitzer's Attack on Market Timers

    This paper explores a natural experiment setup from the 2003-2004 mutual fund scandals to evaluate the effectiveness of implicit regulation on financial markets behavior. On average, buy-and-hold investors lost 218 basis points annually from 1998 to 2002 to market timers. Buy-and-hold investors suffered further economic losses from higher cash holdings, portfolio turnover, fund fees, and substantially lower fund performance that resulted from market timing fund churn. Intensified threat of regulation from the 2003-2004 scandals resulted in the industry's self-regulation by, among other things, voluntary adoption of fair value pricing. I find strong evidence that their self-regulation reduced the market timing motive as well as fund churn in international mutual funds in the post-2004 period, and reduced dilution by 93%.

  5. Evaluating the Implied Cost of Capital Estimates

    Characterizing a firm's true (but unobservable) expected returns as the normative benchmark, we develop a two-dimensional framework for evaluating the relative performance of implied cost-of-capital (ICC) estimates. First, in time-series, variations in ICC estimates should reflect changes in true expected returns rather than changes in measurement errors. Second, cross-sectionally, ICC estimates should predict future realized returns. Using this framework, we compare seven alternative ICC measures and show that several perform quite well along both dimensions, and all do much better than Beta-based estimates. In addition, we provide evidence on the importance of appropriate matching between the earnings forecasting method (analyst vs. mechanical) and the valuation model. Overall, our evidence provides significant support for the broader adoption of ICCs as firm-level expected return proxies.

  2. Say on Pay: Qualcomm, Inc. Shareholders Vote 'Maybe' in 2012

    This case centers around Qualcomm shareholders' 2012 Say-on-Pay vote and the dispute between the Institutional Shareholder Services and management regarding the appropriateness of the CEO's compensation plan. Was ISS right that Qualcomm CEO's pay was inflated and justified by benchmarking to aspirational peers? Or was management correct that its CEO's pay is warranted by Qualcomm's recent firm performance?
