Misvaluing Innovation

Review of Financial Studies 2013 26(3), 635-666
[We demonstrate that a firm's ability to innovate is predictable, persistent, and relatively simple to compute, and yet the stock market appears to ignore the implications of past successes when valuing future innovation. We show that two firms that invest the same in R&D can have quite divergent, but predictably divergent, future paths based on their past track records. A long-short portfolio strategy that takes advantage of the information in past track records earns abnormal returns of roughly 11% annually. Importantly, these past track records also predict divergent future real outcomes in patents, patent citations, and new product innovations.]

Corporate Governance Reform and Executive Incentives: Implications for Investments and Risk Taking

Contemporary Accounting Research 2013 30(4), 1296-1332
We investigate the mechanism through which the Sarbanes Oxley Act ( SOX ) was associated with changes in corporate investment strategies. We document that the passage of the governance regulations in SOX was followed by a significant decline in pay‐performance sensitivity (Delta) and incentives to take risk (Vega) in CEO s' compensation contracts. These changes in compensation contracts are related to a decline in investments, including research and development expenditures, capital investments and acquisitions. Moreover, consistent with the rules in SOX directly affecting CEO s' incentives to take risk, we document that the decline in investments exceeds the amount that would be expected from changes in compensation packages alone. Finally, we also find evidence that the changes in investments are related to lower operating performances of firms, suggesting that these changes were costly to investors. Our evidence speaks to the debate on how corporate governance regulation interacts with firms' and managers' incentives, and ultimately affects corporate operating and investment strategies. Our study suggests that one indirect cost of such regulations in SOX is the significant reductions in corporate risk‐taking activities in the post‐ SOX period. The changes in investments were in part due to changes in executive compensation contracts and in part related to increased executives' personal costs of engaging in risky activities.

How do staggered boards affect shareholder value? Evidence from a natural experiment

Journal of Financial Economics 2013 110(3), 627-641
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 presenting empirical evidence consistent with the market viewing SBs as leading to lower firm value for the affected firms.

Who gets credit after bankruptcy and why? An information channel

Journal of Banking & Finance 2013 37(12), 5101-5117
Conventional wisdom holds that individuals find it difficult to obtain new credit post-bankruptcy. Using credit bureau data, we test this hypothesis and show that more than 90% of bankrupt individuals receive credit shortly after filing. Individuals with good credit history prior to filing have reduced credit availability after bankruptcy while those with ex-ante low credit quality receive more credit. We show that credit supplied to low quality individuals is severely curtailed during the financial crisis. We also find that the default probability on new debt increases after bankruptcy, especially among individuals with high ex-ante credit score. These findings are consistent with an information channel, in which bankruptcy reveals new information about a borrower’s credit quality.

Financial Incentives and Fertility

The Review of Economics and Statistics 2013 95(1), 1-20
Using panel data on over 300,000 Israeli women from 1999 to 2005, we exploit variation in Israel's child subsidy to identify the impact of changes in the price of a marginal child on fertility. We find a positive, statistically significant, and economically meaningful price effect on overall fertility and, consistent with Becker (1960) and Becker and Tomes (1976), a small effect of income on fertility, which is negative at low and positive at high income levels. We also find a price effect on fertility among older women, suggesting that part of the overall effect is due to a reduction in total fertility.

Learning and the disappearing association between governance and returns

Journal of Financial Economics 2013 108(2), 323-348
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.

Legislating stock prices

Journal of Financial Economics 2013 110(3), 574-595 open access
We demonstrate that legislation has a simple, yet previously undetected, impact on stock prices. Exploiting the voting record of legislators whose constituents are the affected industries, we show that the votes of these “interested” legislators capture important information seemingly ignored by the market. A long-short portfolio based on these legislators' views earns abnormal returns of over 90 basis points per month following the passage of legislation. Industries that we classify as beneficiaries of legislation experience significantly more positive earnings surprises and positive analyst revisions in the months following passage of the bill, as well as significantly higher future sales and profitability. We show that the more complex the legislation, the more difficulty the market has in assessing the impact of these bills. Further, the more concentrated the legislator's interest in the industry, the more informative are her votes for future returns.

Misvaluing Innovation

Review of Financial Studies 2013 26(3), 635-666 open access
AFA Meetings in Chicago for helpful comments and suggestions. We are grateful for funding from the We demonstrate that a firm’s ability to innovate is predictable, persistent, and relatively simple to compute, and yet the stock market ignores the implications of past successes when valuing future innovation. We show that two firms that invest the exact same in research and development (R&D) can have quite divergent, but predictably divergent, future paths. Our approach is based on the simple premise that while future outcomes associated with R&D investment are uncertain, the past track records of firms may give insight into their potential for future success. We show that a long-short portfolio strategy that takes advantage of the information in past track records earns abnormal returns of roughly 11 percent per year. Importantly, these past track records also predict divergent future real outcomes in patents, patent citations, and new product innovations. Firms engage in a variety of activities. Some of these activities are straightforward, and easy to assess how they will impact firm value (e.g., maintenance capital expenditures). However, some of these activities, while crucially important for the discounted value of a
