Product and process productivity: Implications for quality choice and conditional exporter premia

We develop a model of international trade with two dimensions of firm heterogeneity. The first dimension is “process productivity”, which is how we denote the standard concept of productivity as modeled in the literature. The second one is “product productivity”, defined as firms' ability to develop high-quality products spending small fixed outlays. The distinction between these two sources of productivity, together with the assumption that iceberg trade costs decrease with quality, delivers various conditional exporter premia as theoretical predictions. Conditional on size, exporters sell higher quality products, charge higher prices, pay higher input prices and higher wages, and use capital more intensively. Some of these predictions had already been documented in the empirical literature but lacked a theoretical framework for properly interpreting them. We conduct systematic tests of these predictions using manufacturing establishment data for India, the U.S., Chile, and Colombia, and find strong support for the model.     

Asleep at the Wheel (Again)? Bank Audits During the Lead‐Up to the Financial Crisis

We present the first large‐sample empirical evidence on U.S. auditors' responses to changes in entity‐level audit risk during 2006–2007, the period leading up to the financial crisis of 2008–2009. Treating fiscal year 2005 engagements as a pre‐crisis benchmark, we find that audit attention during fiscal year 2006 and 2007 bank audit engagements shifted in line with the shifting audit risks. One implication of these findings is that auditors were able to recognize and respond to financial statement impacts of the macroeconomic shocks that unfolded during the lead‐up to the crisis. Another implication is that auditors' failure to issue advance warnings of increasing auditee riskiness during the time leading up to the financial crisis more likely reflects limitations of extant accounting and auditing rules rather than a lack of auditor awareness or attention to those risks.     

The composite dividend tax rate

Dividends often impose taxes on investors. However, as certain prior financial models indicate, they also can produce a tax gain from leverage. Hence the composite marginal dividend tax rate can be specified as the nominal rate minus the offsetting tax gain from leverage. Although this principle has been embedded in theoretical models for more than 40 years, no prior study has examined empirically whether the dividend-induced tax gain from leverage influences dividend policy. We address this empirical void and find dividends decrease in the nominal dividend tax rate and increase in the offsetting tax gain from leverage. In addition, we find the composite tax rate outperforms traditional measures in explaining dividend policy for our full sample of firms. Consistent with prior theory, we also find the composite rate varies in influence according to the financing source for a dividend.     

Barriers to Entry and Competitive Behavior: Evidence from Reforms of Cable Franchising Regulations

Between 2005 and 2008, nineteen of the fifty states of the U.S. reformed the franchising process for cable television, significantly easing entry into local markets. Using a difference‐in‐differences approach that exploits the staggered introduction of reforms, we find that prices for ‘Basic’ service declined systematically by about 5.5 to 6.8 per cent following the reforms, but we find no statistically significant effect on average price for the more popular ‘Expanded Basic’ service. We also find that the reforms led to increased actual entry in reformed states, by about 11.6% relative to non‐reformed states. Our analysis shows that the decline in price for ‘Basic’ service holds for markets that did not experience actual entry, consistent with limit pricing by incumbents. To control for potential state‐level shocks correlated with the reforms, we undertake a sample‐split test that finds larger declines in prices for both ‘Basic’ and ‘Expanded Basic’ services in local markets which faced a greater threat of entry (because they were close to a prominent second entrant). Our results are consistent with limit pricing models that predict incumbents respond to increased threat of entry, and suggest that the reforms facilitated entry and modestly benefited consumers in reformed states.
