In Search of Labor Demand

American Economic Review 2018 108(9), 2714-2757 open access
We propose and estimate a novel specification of the labor demand curve incorporating search frictions and the role of entrepreneurs in new firm creation. Using city-industry variation over four decades, we estimate the employment -wage elasticity to be -1 at the industry-city level and -0.3 at the city level. We show that the difference between these estimates likely reflects the congestion externalities predicted by the search literature. Also, holding wages constant, an increase in the local population is associated with a proportional increase in employment. These results provide indirect information about the elasticity of job creation to changes in profits.

Is Sell‐Side Research More Valuable in Bad Times?

Journal of Finance 2018 73(3), 959-1013
Because uncertainty is high in bad times, investors find it harder to assess firm prospects and hence should value analyst output more. However, higher uncertainty makes analysts’ tasks harder, so it is unclear whether analyst output is more valuable in bad times. We find that in bad times, analyst revisions have a larger stock‐price impact, earnings forecast errors per unit of uncertainty fall, and analyst reports are more frequent and longer. The increased impact of analysts is also more pronounced for harder‐to‐value firms. These results are consistent with analysts working harder and investors relying more on analysts in bad times.

Institutional and Legal Context in Natural Experiments: The Case of State Antitakeover Laws

Journal of Finance 2018 73(2), 657-714
We argue and demonstrate empirically that a firm's institutional and legal context has first‐order effects in tests that use state antitakeover laws for identification. A priori, the size and direction of a law's effect on a firm's takeover protection depends on (i) other state antitakeover laws, (ii) preexisting firm‐level takeover defenses, and (iii) the legal regime as reflected by important court decisions. In addition, (iv) state antitakeover laws are not exogenous for many easily identifiable firms. We show that the inferences from nine prior studies related to nine different outcome variables change substantially when we include controls for these considerations.

Supplier Internal Control Quality and the Duration of Customer-Supplier Relationships

The Accounting Review 2018 93(3), 59-82
Internal controls influence information quality, thus affecting the ability of supply chain partners, who rely on collaborative systems of information sharing, to reliably contract. Using SOX-related internal control assessments as a proxy for internal control quality and U.S. GAAP-mandated major customer disclosures, we find that supplier internal control quality influences supply chain relationship duration. Specifically, our evidence demonstrates that: (1) poor internal control quality increases the likelihood of subsequent customer-supplier relationship termination; (2) timely control weakness remediation attenuates termination likelihood; and (3) weaknesses affecting customer contracting drive the effect of internal control quality on relationship termination. Our results control for supplier operational quality and performance, and are robust to propensity score matching techniques, controls for reverse causality, and alternative proxies for relationship termination and internal control quality. Overall, our findings are consistent with customers viewing strong supplier controls as important, albeit overlooked, contracting elements with significant implications for supply chain relationships.

Does Fair Value Accounting Provide More Useful Financial Statements than Current GAAP for Banks?

The Accounting Review 2018 93(6), 257-279
Standard setters contend that fair value accounting yields the most relevant measurement for financial instruments. We examine this claim by comparing the value relevance of banks' financial statements under fair value accounting with that under current GAAP, which is largely based on historical costs. We find that the combined value relevance of book value of equity and income under fair value is less than that under GAAP. We also find that fair value income is less value-relevant than GAAP income because of the inclusion of transitory unrealized gains and losses in fair value income. More surprisingly, we find that book value of equity under fair value is not more value-relevant than under GAAP, due both to divergence between exit value and value-in-use and to measurement error in fair value estimates. Overall, our results suggest that financial statements under fair value accounting provide less relevant information for bank valuation than financial statements under current GAAP.

Custom Contrast Testing: Current Trends and a New Approach

The Accounting Review 2018 93(5), 223-244
Contrast analysis has become prevalent in experimental accounting research since Buckless and Ravenscroft (1990) introduced it to the accounting literature over 25 years ago. Since its initial introduction, the scope of contrast testing has expanded, yet guidance as to the most appropriate methods of specifying, conducting, interpreting, and exhibiting these tests has not. We survey the use of contrast analysis in the recent literature and propose a three-part testing approach that provides a more comprehensive picture of contrast results. Our approach considers three pieces of complementary evidence: the visual evaluation of fit, traditional significance testing, and quantitative evaluation of the contrast variance residual. Our measure of the contrast variance residual, q2, is proposed for the first time in this work. After proposing our approach, we walk through six common contrast testing scenarios where current practices may fall short and our approach may guide researchers. We extend Buckless and Ravenscroft (1990) and contribute to the accounting research methods literature by documenting current contrast analysis practices that result in elevated Type I error and by proposing a potential solution to mitigate these concerns.

Evaluating Strategic Forecasters

American Economic Review 2018 108(10), 3057-3103
Motivated by the question of how one should evaluate professional election forecasters, we study a novel dynamic mechanism design problem without transfers. A principal who wishes to hire only high-quality forecasters is faced with an agent of unknown quality. The agent privately observes signals about a publicly observable future event, and may strategically misrepresent information to inflate the principal’s perception of his quality. We show that the optimal deterministic mechanism is simple and easy to implement in practice: it evaluates a single, optimally timed prediction. We study the generality of this result and its robustness to randomization and noncommitment.

Immigration Restrictions as Active Labor Market Policy: Evidence from the Mexican Bracero Exclusion

American Economic Review 2018 108(6), 1468-1487 open access
An important class of active labor market policy has received little impact evaluation: immigration barriers intended to raise wages and employment by shrinking labor supply. Theories of endogenous technical advance raise the possibility of limited or even perverse impact. We study a natural policy experiment: the exclusion of almost half a million Mexican bracero farm workers from the United States to improve farm labor market conditions. With novel labor market data we measure state-level exposure to exclusion, and model the absent changes in technology or crop mix. We fail to reject zero labor market impact, inconsistent with this model.

The Leverage Ratchet Effect

Journal of Finance 2018 73(1), 145-198
Firms’ inability to commit to future funding choices has profound consequences for capital structure dynamics. With debt in place, shareholders pervasively resist leverage reductions no matter how much such reductions may enhance firm value. Shareholders would instead choose to increase leverage even if the new debt is junior and would reduce firm value. These asymmetric forces in leverage adjustments, which we call the leverage ratchet effect , cause equilibrium leverage outcomes to be history‐dependent. If forced to reduce leverage, shareholders are biased toward selling assets relative to potentially more efficient alternatives such as pure recapitalizations.

Off the Charts: Massive Unexplained Heterogeneity in a Global Study of Ambiguity Attitudes

The Review of Economics and Statistics 2018 100(4), 664-677 open access
Ambiguity attitudes have been prominently used in economic models, but we still know little about their demographic correlates or their generalizability beyond the West. We analyze the ambiguity attitudes of almost 3,000 students across thirty countries. For gains, we find ambiguity aversion everywhere, while ambiguity aversion is much weaker for losses. Ambiguity attitudes change systematically with probabilities for both gains and losses. Much of the between-country variation can be explained through a fewmacroeconomic characteristics. In contrast, we find massive unexplained variation at the individual level. We also find much unexplained heterogeneity in individual responses to different decision tasks.
