We investigate market behavior in a setting where managerial incentives to manipulate earnings and market price should be apparent ex ante to market participants. We find evidence of abnormally low discretionary accruals in the period following announcements of cancellations of executive stock options up to the time the options are reissued. Nevertheless, analysts and investors are not misled. Discretionary accruals have little power in explaining stock price performance during this period. Moreover, discretionary accruals do not explain subsequent analyst forecast errors. Thus, our findings suggest that, in this transparent setting, analysts and investors do not respond to earnings management.

We devise a tractable model of firm dynamics with on-the-job search. The model admits analytical solutions for equilibrium outcomes, including quit, layoff, hiring, and vacancy-filling rates, as well as the distributions of job values, a fundamental challenge posed by the environment. Optimal labor demand takes a novel form whereby hiring firms allow their marginal product to diffuse over an interval. The evolution of the marginal product over this interval endogenously exhibits gradual mean reversion, evoking a notion of imperfect labor market competition. This in turn contributes to dispersion in marginal products, giving rise to endogenous misallocation. Quantitatively, the model provides a parsimonious reconciliation of leading estimates of rent sharing, the negative association between wages and quits, the link between job and worker flows, and the cyclicality of labor market quantities and prices.

This paper provides early evidence on the integration and impact of generative artificial intelligence (GenAI) in accounting at the accountant and task levels. Using survey data from 277 professional accountants, we document substantial heterogeneity in adoption patterns, perceived benefits, and concerns about GenAI. Using proprietary field data from an AI‐enabled accounting platform serving 79 small‐ and medium‐sized enterprises, we analyze over 200,000 transaction‐level records. We document that GenAI adoption is associated with significant productivity gains and systematic reallocation of effort away from routine data entry toward business communication and quality assurance tasks. GenAI use is also associated with improvements to financial reporting quality, evidenced by more granular ledgers and faster month‐end closing. Examining human–AI interaction, we find that accountants selectively intervene when AI confidence scores are low, consistent with complementarity between professional expertise and AI. A framed field experiment further shows that while AI assistance improves classification accuracy on average, reliance on non‐consensus AI recommendations can increase the risk of error. Overall, our findings highlight both the promise and the risks of GenAI in accounting and suggest that, in practice, AI is most effective as a tool that augments—rather than replaces—professional judgment.

We investigate whether Public Company Accounting Oversight Board (PCAOB) inspections affect the quality of internal control audits. Our research design improves on prior studies by exploiting both cross-sectional and time-series variation in the content of PCAOB inspection reports, while also controlling for audit firm and year fixed effects, effectively achieving a difference-in-differences research design. We find that when PCAOB inspectors report higher rates of deficiencies in internal control audits, auditors respond by increasing the issuance of adverse internal control opinions. We also find that auditors issue more adverse internal control opinions to clients with concurrent misstatements, who thus genuinely warrant adverse opinions. We further find that higher inspection deficiency rates lead to higher audit fees, consistent with PCAOB inspections prompting auditors to undertake costly remediation efforts. Taken together, our results are consistent with the PCAOB inspections improving the quality of internal control audits by prompting auditors to remediate deficiencies in their audits of internal controls.

How does the formation of cross-country teams affect the organization of work and the structure of wages? To study this question, we propose a theory of the assignment of heterogeneous agents into hierarchical teams, where less skilled agents specialize in production and more skilled agents specialize in problem solving. We first analyze the properties of the competitive equilibrium of the model in a closed economy, and show that the model has a unique and efficient solution. We then study the equilibrium of a two-country model (North and South), where countries differ in their distributions of ability, and in which agents in different countries can join together in teams. We refer to this type of integration as globalization. Globalization leads to better matches for all southern workers but only for the best northern workers. As a result, we show that globalization increases wage inequality among nonmanagers in the South, but not necessarily in the North. We also study how globalization affects the size distribution of firms and the patterns of consumption and trade in the global economy.

The fact that incumbent firms can immediately deduct research and development (R&D) investments from taxable income is generally believed to give them a strategic advantage over new firms that cannot deduct the investment cost, but instead generate a net operating tax loss carryover. Using an analytical model, we show that this conventional wisdom need not hold in a competitive environment. We examine operating and investment decisions in a duopolistic industry in which an initial investment in R&D yields an immediate tax benefit for one firm, but creates a net operating loss carryover for the other firm. If both firms invest in R&D, the firm with the net operating loss carryover makes more aggressive capital investment decisions following successful R&D. This may deter the incumbent firm from investing in R&D despite the lower aftertax costs of this investment. Changing the tax loss carryover rules would thus not only affects start‐up or loss firms, but would also affect the investment decisions of profitable firms in the same industry.

Prior to the Sarbanes–Oxley Act of 2002, audit partners experienced economic pressure to grow revenue from the sale of nonaudit services to their audit clients. To an auditor who is highly rewarded for revenue generation and growth, nonaudit services may represent a particularly strengthened economic bond with the client. Prior research shows that, in general, nonaudit service fees received in the current period do not impair audit quality. We examine a different setting. We propose that auditor independence can become impaired, and audit quality compromised, when clients that currently purchase relatively low amounts of nonaudit services, increase their purchases of nonaudit services from the auditor in the subsequent period. We test our prediction in the context of earnings management as a proxy for audit quality, measured by (a) performance‐adjusted discretionary accruals and (b) classification shifting of core expenses. Our results indicate that prior to the Sarbanes‐Oxley Act, rewards to the auditor in the form of future additional nonaudit service fees from current‐year high fee‐growth‐opportunity clients adversely affects audit quality. This effect is particularly strong among companies with powerful incentives to manage earnings. Our findings indicate that regulators should consider the multiperiod nature of the client–auditor relationship when contemplating policies that restrict nonaudit services, as well as the overall environment in which audit partners operate. This might include partner compensation arrangements that put pressure on audit partners to focus on increasing revenue at the expense of audit quality.

We examine the relationship between income volatility and life expectancy in mid-sized U.S. commuting zones between 2006 and 2014. We use a commercial dataset, InfoUSA, to measure income volatility which we link to estimates of life expectancy by gender, county, race, and income. We find that higher income volatility in a county is associated with lower life expectancy, but only at the bottom of the income distribution and primarily for non-Hispanic Whites. Though we cannot extrapolate our findings to individual-level relationships, we do link them to existing literatures on place-based differences in mortality and the relationship between volatility and health.

We propose a model of intergenerational transmission of education wherein children belong to either highly educated or low-educated families. Children choose the intensity of their social activities, while parents decide how much educational effort to exert. Using Add Health data, we find that, on average, children’s homophily acts as a complement to the educational effort of highly educated parents but as a substitute for the educational effort of low-educated parents. We also find that policies that subsidize kids’ socialization efforts can backfire for low-educated students because they tend to increase their interactions with other low-educated students.
