Capitalization of software research and development costs (SDC) under SFAS No. 86 is the only exception to SFAS No. 2 which calls for immediate expensing of R&D costs. Although intangible assets have become increasingly relevant for firm valuation, they remain largely unexplored in audit...

What are the implications of major customer dependency, i.e., the degree of a supplier firm's dependency on its major customers, for external auditors? While the conventional view emphasizes the negatives of major customer dependency for client business risk, we find that suppliers with more...

This paper develops an overlapping generations model of optimal rebalancing where agents differ in age and risk tolerance. Equilibrium rebalancing is driven by a leverage effect that influences levered and unlevered agents in opposite directions, an aggregate risk tolerance effect that depends...

Standard portfolio advice is that agents should hold a constant share of risky assets. All agents cannot, however, follow this advice because supply and demand of risky assets must be equal. To study equilibrium rebalancing, the paper develops an overlapping generations model in which agents...

This paper investigates the welfare gains from European trade integration, and the role of comparative advantage in determining the magnitude of those gains. We use a multisector Ricardian model implemented on 79 countries, and compare welfare in the 2000s to a counterfactual scenario in which...

We develop a dynamic equilibrium model of labor demand with adverse selection. Firms learn the quality of newly hired workers after a period of employment. Adverse selection makes it costly to hire new workers and to release productive workers. As a result, firms hoard labor and under-react to...

This paper evaluates the role of sectoral heterogeneity in determining the gains from trade. We first show analytically that in the presence of sectoral Ricardian comparative advantage, a one- sector sufficient statistic formula that uses total trade volumes as a share of total absorption...

We develop a structural framework to identify the sources of cross-state heterogeneity in response to US tariff changes. We quantify the effects of unilaterally increasing US tariffs by 25 percentage points across sectors. Welfare changes range from −0.8 percent in Oregon to 2.1 percent in...
