Whether or not the use of remote work increases firm labour productivity is theoretically ambiguous. We use a rich and representative sample of Portuguese firms, and within-firm variation in the policy on remote work, over the period 2011-2016, to empirically assess the causal productivity...

We study the effects of horizontal mergers when firms compete on quality and price. Two key factors are identified: (i) the magnitude of variable quality costs, and (ii) the relative magnitudes of cross-quality and cross-price effects on demand. The merging firms will increase (reduce) both...

This paper studies the effects of price regulation and parallel imports in the on-patent pharmaceutical market. In a theory model where the producer price is subject to bargaining between the brand-name producer and a distributor, we show that the effects of stricter price regulation crucially...

Patient mobility is a key issue in the EU who recently passed a new law on patients’ right to EU-wide provider choice. In this paper we use a Hotelling model with two regions that differ in technology to study the impact of patient mobility on health care quality, health care financing and...

In a spatial competition setting there is usually a non-negative relationship between competition and quality. In this paper we offer a novel mechanism whereby competition leads to lower quality. This mechanism relies on two key assumptions, namely that the providers are motivated and...

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...

We consider a therapeutic market with potentially three pharmaceutical firms. Two of the firms offer horizontally differentiated brand-name drugs. One of the brand-name drugs is a new treatment under patent protection that will be introduced if the profits are sufficient to cover the entry...

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...

We analyse how a patent-holding pharmaceutical firm may strategically use advertising of existing drugs to affect R&D investments in new (differentiated) drugs, and thereby affect the probability distribution of future market structures in the industry. Within a fairly general model framework,...
