Although measures of sensitivity to inequality are important in judging the welfare effects of health-care programmes, it is far from straightforward how to elicit them and apply them in health-care decision making. This paper provides an overview of the literature on the measurement of...

We examine friendships and study partnerships among university students over several years. At the aggregate level, connections increase over time, but homophily on gender and ethnicity is relatively constant across time, university residences, and different network layers. At the individual...

How does immigration affect export performance? To answer this question we propose a unified empirical framework allowing to disentangle various mechanisms such as the role of networks in reducing bilateral transaction costs as well as productivity shifts arising from migration-induced knowledge...

Companies typically control various aspects of their workers’ behaviors. In this paper, we investigate whether the hierarchical distance of the superior who imposes such control measures matters for the workers’ ensuing reaction. In particular, we test, in a laboratory experiment, whether...

We develop a dynamic model of hospital competition where (i) waiting times increase if demand exceeds supply; (ii) patients choose a hospital based in part on waiting times; and (iii) hospitals incur waiting time penalties. We show that, whereas policies based on penalties will lead to lower...

This paper studies the impact of hospital competition on waiting times. We use a Salop-type model, with hospitals that differ in (geographical) location and, potentially, waiting time, and two types of patients; high-benefit patients who choose between neighbouring hospitals (competitive...

In this paper, we develop a network perspective on the welfare gains from trade in today’s internationally fragmented supply chains. Towards this end, we study a Ricardian trade model featuring trade in final and intermediate products, and introduce a novel comparative statics approach to...
