This paper considers cost-reducing R&D investment with spillovers in a Cournot oligopoly with overlapping ownership. We show that overlapping ownership leads to internalization of rivals. profits by firms and find that, for demand not too convex, increases in overlapping ownership increase (decrease) R&D and output for high (low) enough spillovers while it increases R&D but decreases output for intermediate levels of spillovers. There is scope for overlapping ownership to improve welfare provided that spillovers are sufficiently large. The socially optimal degree of overlapping ownership increases with the number of firms, with the elasticity of demand and of the innovation function, and with the extent of spillover effects. In terms of consumer surplus standard, the desirability of overlapping ownership is greatly reduced even under low market concentration. When R&D has commitment value and spillovers are high the optimal extent of overlapping ownership is higher. The results obtained are robust in the context of a Bertrand oligopoly model with product differentiation.

ABSTRACT This paper examines the demand- and supply-side factors associated with audit partner selection and assignment in the United States. First, we examine whether audit partner gender and experience are associated with board and management gender and experience. Second, we investigate whether engagement audit quality varies with audit partner gender and experience, controlling for selection effects. The results indicate that companies with more gender-diverse boards of directors and top management teams are more likely to have a female lead audit partner. In addition, the experience of the client's board is positively associated with the experience of the lead audit partner. In terms of audit quality, we find that higher audit fees are positively associated with female and more experienced audit partners. Our results shed light on the important role that partner characteristics play in the demand and supply sides of audit quality.

Oligopoly models of price competition predict that strategic firms exercise market power and generate inefficiencies. However, heterogeneity in firms’ strategic ability also generates inefficiencies. We study the Texas electricity market where firms exhibit significant heterogeneity in how they deviate from Nash equilibrium bidding. These deviations, in turn, increase the cost of production. To explain this heterogeneity, we embed a cognitive hierarchy model into a structural model of bidding and estimate firms’ strategic sophistication. We find that firm size and manager education affect sophistication. Using the model, we show that mergers which increase sophistication can increase efficiency despite increasing market concentration. (JEL D24, D43, G34, L13, L25, L94)

ABSTRACT We investigate the relation between tax avoidance and tax uncertainty, where tax uncertainty is the amount of unrecognized tax benefits recorded over the same time period as the tax avoidance. On average, we find that tax avoiders, i.e., firms with relatively low cash effective tax rates, bear significantly greater tax uncertainty than firms that have higher cash effective tax rates. We find that the relation between tax avoidance and tax uncertainty is stronger for firms with frequent patent filings and tax haven subsidiaries, proxies for intangible-related transfer pricing strategies. The findings have implications for several puzzling results in the literature.

ABSTRACT We find that firms that grant performance-contingent (p-c) equity awards with accounting-based vesting conditions to their CEOs have lower cost of debt and less restrictive loan terms. The benefits of p-c accounting-based awards on debt financing are greater when the moral hazard problem faced by debtholders is potentially more significant—for example, for firms with poorer credit ratings and lower asset tangibility. We find some evidence that certain types of p-c equity awards with stock price-based conditions increase the cost of debt financing. The adoption of p-c accounting-based awards increases firm value, as indicated by stock and bond event studies. Overall, our findings suggest that the incentive compatibility of accounting-based p-c awards mitigates the potential agency conflict between shareholders and debtholders.

ABSTRACT We examine the strategic effects of auditor tenure on the auditor's testing strategy and the manager's inclination to commit fraud. Most empirical studies conclude that longer tenure improves audit quality. Proponents of restricting tenure argue that longer tenure impairs auditor independence and a “fresh look” from a new auditor results in higher audit quality. Validating this argument requires testing whether the observed difference in audit quality between a continuing auditor and a change in auditors is less than the theoretically expected difference in audit quality without impairment. Our findings provide the guidance necessary for developing such tests. Our results show that audit risk (the probability that fraud exists and goes undetected) is lower in both periods for the continuing auditor than with a change in auditors. More importantly, we show that across both periods, expected undetected fraud is lower for the continuing auditor than with a change in auditors.

ABSTRACT The quality of financial statement (FS) audits integrated with audits of internal controls over financial reporting (ICFR) depends upon the quality of ICFR information used in, and its integration into, FS audits. Recent research and PCAOB inspections find auditors underreport existing ICFR weaknesses and perform insufficient testing to address identified risks, suggesting integrated audits—in which substantial ICFR testing is required—may result in lower FS audit quality than FS-only audits. We compare a 2007–2013 sample of small U.S. public company firm-years receiving integrated audits (accelerated filers) to firm-years receiving FS-only audits (non-accelerated filers) and find integrated audits are associated with higher likelihood of material misstatements and discretionary accruals, consistent with lower FS audit quality. We also find evidence of (1) auditor judgment-based integration issues, and (2) low-quality ICFR audits harming FS audit quality. Overall, results suggest an important potential consequence of integrated audits is lower FS audit quality. Data Availability: Data are publicly available from the sources identified in the text.

We examine the equilibrium effects of college financial aid policies building an overlapping-generations life cycle model with education, labor supply, and saving decisions. Cognitive and noncognitive skills of children depend on parental education and skills and affect education and labor market outcomes. Education is funded by parental transfers that supplement grants, loans, and student labor supply. Crowding out of parental transfers by government programs is sizable and cannot be ignored. The current system of federal aid improves long-run welfare by 6 percent. More generous ability-tested grants would increase welfare and dominate both an expansion of student loans and a labor tax cut.
