Consider a model with two types of jobs. The profitability of promoting a worker to a fast-track job depends not only on his or her observable talent, but also on incontractible effort. We investigate whether self-fulfilling expectations may lead to higher promotion standards for women. If...

We analyse the effects of different labour market policies — employment protection, unemployment benefits and payroll taxes — on job creation and technology choices in a model where firms are randomly matched with workers of different productivity and wages are determined by ex-post...

In this paper we study the effect of reference pricing on pharmaceutical prices and expenditures when generic entry is endogenously determined. We develop a Salop-type model where a brand-name producer competes with generic producers in terms of prices. In the market there are two types of...

Using a spatial competition framework with three ex ante identical firms, we study the effects of a horizontal merger on quality, price and welfare. The merging firms always reduce quality. They also increase prices if demand responsiveness to quality is sufficiently low. The non-merging firm,...

We examine if an expansion in the supply of public preschool crowds-out private enrollment using rich data for municipalities in Brazil from 2000-2006, where federal transfers to local governments change discontinuously with given population thresholds. Results from a regression-discontinuity...

This paper studies the effects of price regulation and parallel imports in the onpatent pharmaceutical market. First, we develop a theory model in which a pharmacy negotiates producer prices with a brand-name firm and then sets retail prices. We show that the effects of price regulation...

We study the incentives for hospitals to provide quality and expend cost-reducing effort when their budgets are soft, i.e., the payer may cover deficits or confiscate surpluses. The basic set up is a Hotelling model with two hospitals that differ in location and face demand uncertainty, where...

We study the effect of competition on quality in markets such as health care, long-term care and education, when providers choose both prices and quality in a setting of spatial competition. We offer a novel mechanism whereby competition leads to lower quality. This mechanism relies on two key...

We examine whether and how rainfall shocks affect tariff setting in the agricultural sector. In a model of international oligopoly, we show that the impact of a negative rainfall shock on optimal import tariffs is generally ambiguous, depending on the weight placed by the domestic policy maker...

We study the effects of a hospital merger using a spatial competition framework with semialtruistic hospitals that invest in quality and expend cost-containment effort facing regulated prices. We find that the merging hospitals always reduce quality, whereas non-merging hospitals respond by...
