Necessity Is the Mother of Invention: Input Supplies and Directed Technical Change

Econometrica 2015 83(1), 67-100 open access
This study provides causal evidence that a shock to the relative supply of inputs to production can (1) affect the direction of technological progress and (2) lead to a rebound in the relative price of the input that became relatively more abundant (the strong induced-bias hypothesis). I exploit the impact of the U.S. Civil War on the British cotton textile industry, which reduced supplies of cotton from the Southern United States, forcing British producers to shift to lower-quality Indian cotton. Using detailed new data, I show that this shift induced the development of new technologies that augmented Indian cotton. As these new technologies became available, I show that the relative price of Indian/U.S. cotton rebounded to its pre-war level, despite the increased relative supply of Indian cotton. This is the first paper to establish both of these patterns empirically, lending support to the two key predictions of leading directed technical change theories.

Territorial Tax System Reform and Corporate Financial Policies

Review of Financial Studies 2015 28(8), 2250-2280
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.

Making Sense of One Dollar CEO Salaries

Contemporary Accounting Research 2015 32(3), 941-972
Abstract We examine the determinants and outcomes of Chief Executive Officers ( CEO s) accepting a $1 salary, a compensation practice that occurs relatively frequently in high‐profile firms and is debated by regulators, investors, and the media. Using a hand‐collected sample of 93 CEO s from 91 firms between 1993 and 2011, we examine the triggers preceding the $1 salary decision, the factors associated with the decision, subsequent stock returns, and the outcomes for the CEO s. Our evidence is consistent with two explanations for the phenomenon: (i) it is a gesture of sacrifice by CEO s of firms in crisis, and (ii) it is a signal of better future performance by CEO s of growing firms. Our analyses highlight the two different circumstances and shed light on an interesting debate that has thus far been supported only by anecdotal evidence.

Foreign Institutional Ownership and the Global Convergence of Financial Reporting Practices

Journal of Accounting Research 2015 53(3), 593-631
ABSTRACT This paper investigates whether foreign institutional investors affect the global convergence of financial reporting practices. Using several measures of reporting convergence, we show that U.S. institutional ownership is positively associated with subsequent changes in emerging market firms’ accounting comparability to their U.S. industry peers. We identify this association using an instrumental variable approach that exploits exogenous variation in U.S. institutional investment generated by the JGTRRA Act of 2003. Further, we provide evidence of a specific mechanism—the switch to a Big Four audit firm—through which U.S. institutional investors affect reporting convergence. Finally, we show that, for emerging market firms, an increase in comparability to U.S. firms is associated with an improvement in the properties of foreign analysts’ forecasts.

Optimal Contracting and the Organization of Knowledge

Review of Economic Studies 2015 82(2), 632-658
We study contractual arrangements that support an efficient use of time in a knowledge-intensive economy in which agents endogenously specialize in either production or consulting. The resulting market for advice is plagued by informational problems, since both the difficulty of the questions posed to consultants and the knowledge of those consultants are hard to assess. We show that spot contracting is not efficient because lemons (in this case, self-employed producers with intermediate knowledge) cannot be appropriately excluded from the market. However, an ex ante, firm-like contractual arrangement uniquely delivers the first best. This arrangement involves hierarchies in which consultants are full residual claimants of output and compensate producers via incentive contracts. This simple characterization of the optimal ex ante arrangement suggests a rationale for the organization of firms and the structure of compensation in knowledge-intensive sectors. Our findings correspond empirically to observed arrangements inside professional service firms and between venture capitalists and entrepreneurs.

Audit Firm Tenure, Non‐Audit Services, and Internal Assessments of Audit Quality

Journal of Accounting Research 2015 53(3), 461-509
ABSTRACT We use data from internal assessments of audit quality in a Big 4 firm to investigate the impact of audit firm tenure and auditor‐provided non‐audit services (NAS) on audit quality. We find that first‐year audits receive lower assessments of audit quality and that quality improves shortly thereafter and then declines as tenure becomes very long. Partitioning our sample between SEC registrants and private clients, we find that the decline in audit quality in the long tenure range is attributable to audits of private clients. For audits of SEC registrants, the probability of a high quality audit reaches its maximum with very long tenure. We also find that audit fees are discounted for first‐year audits but auditor effort is higher than in subsequent years. We find no association, on average, between total NAS fees and audit quality in the full sample but observe that total NAS fees are positively associated with quality for SEC registrants and negatively associated with quality for privately held clients. Our findings are important for regulatory policies related to audit firm tenure and auditor‐provided NAS.

Board Structure and Monitoring: New Evidence from CEO Turnovers

Review of Financial Studies 2015 28(10), 2770-2811
We use the 2003 NYSE and NASDAQ listing rules for board and committee independence as a quasinatural experiment to examine the causal relations between board structure and CEO monitoring. Noncompliant firms forced to raise board independence or adopt a fully independent nominating committee significantly increased their forced CEO turnover sensitivity to performance relative to compliant firms. Nominating committee independence is important even when firms had an independent board, and the effect is stronger when the CEO is on the committee. We conclude that greater board independence and full independence of nominating committees lead to more rigorous CEO monitoring and discipline.

The Cost of Capital for Alternative Investments

Journal of Finance 2015 70(5), 2185-2226
ABSTRACT Traditional risk factor models indicate that hedge funds capture pre‐fee alphas of 6% to 10% per annum over the period from 1996 to 2012. At the same time, the hedge fund return series is not reliably distinguishable from the returns of mechanical S&P 500 put‐writing strategies. We show that the high excess returns to hedge funds and put‐writing are consistent with an equilibrium in which a small subset of investors specialize in bearing downside market risks. Required rates of return in such an equilibrium can dramatically exceed those suggested by traditional models, affecting inference about the attractiveness of these investments.

Earnings Metrics, Information Processing, and Price Efficiency in Laboratory Markets

Journal of Accounting Research 2015 53(3), 555-592
ABSTRACT An enduring issue in financial reporting is whether and how salient summary measures of firm performance (“earnings metrics”) affect market price efficiency. In laboratory markets, we test the effects of salient earnings metrics, which vary in how they combine persistent and transitory elements, on investor information search, beliefs about value, offers to trade, and market price efficiency. We find that including transitory elements in salient earnings metrics causes traders to search unnecessarily for further information about these elements and to overestimate their effect on fundamental value relative to a rational benchmark. In contrast, separately displaying persistent elements in earnings increases the accuracy of traders’ value estimates. Prices generally reflect traders’ beliefs about value, and prices are most efficient when transitory elements are excluded from earnings metrics entirely. Our study contributes to research on salience effects in financial reporting by showing that including transitory elements in salient earnings metrics causes inefficient information search and biased beliefs about value that can aggregate to affect market prices. We also contribute to research in experimental markets by showing that redundant disclosure is not always beneficial; redundant disclosure of transitory earnings elements, in particular, appears to have negative consequences for investor behavior and market efficiency.
