This paper develops an open economy model with heterogeneous final goods producers who simultaneously choose whether to export their goods and whether to use imported intermediates. The model highlights mechanisms whereby import policies affect aggregate productivity, resource allocation, and...

France has seen a marked deterioration in its export performance in the last 10 years or so. Previous empirical research pointed out that weak export performance was due to i) vigorous domestic demand; ii) lower mark-ups due to head-to-head competition with Germany; iii) low non-price...

We illustrate a new source of comparative advantage that is generated by countries' different ability to adjust to technological change. Our model introduces substitution of workers in codifiable (routine) tasks with more efficient machines, a process extensively documented in the labor...

I first summarize and critically discuss the different normative views that are operational in the academic literature on education. Afterwards, I analyze how prioritarians would allocate resources in a dynamic model of skill formation and compare it to utilitarians and Rawlsians. I finish with...

We study the role of inter-group differences in the emergence of conflict. In our setting, two groups compete for the right to allocate societys resources, and we allow for costly intergroup mobility. The winning group offers an allocation, that the opposition can either accept, or reject and...

Trade and innovation cause structural change. Productive factors must flow from declining to growing industries. Banks play a major role in cutting credit to non-viable firms in downsizing sectors and in providing new credit to finance investment in expanding, innovative sectors. Structural...

This paper studies the employment and reallocation effects of minimum wages in Germany in a search-and-matching model with endogenous job search effort and vacancy posting, multiple employment levels, a progressive tax-transfer system, and worker and firm heterogeneity. I find that minimum wages...

How do banks facilitate creative destruction and shape firm turnover? We develop a dynamic general equilibrium model of bank credit reallocation with endogenous firm entry and exit that allows for both theoretical and quantitative analysis. By restructuring loans to firms with poor prospects and...

For reward-based crowdfunding, we introduce the strategy-proof Generalized Moulin-Shenker mechanism (GMS) and compare its performance to the prevailing All-Or-Nothing mechanism (AON). Theoretically, GMS outperforms AON in equilibrium profit and funding success. We test these predictions...

Recent trade agreements have shifted their focus to non-tariff barriers such as regulations and product standards, which have been traditionally treated as pure domestic policies. The imposition of such standards reallocates production from small to large, high quality firms. We model...
