Competition and physician behaviour: Does the competitive environment affect the propensity to issue sickness certificates?
(DP SAM;3, Working paper, 2017)
Competition among physicians is widespread, but compelling empirical evidence on the impact on service provision is limited, mainly due to lack of exogenous variation in the degree of competition. In this paper we exploit ...
Price and quality in spatial competition
(Discussion paper2009:11, Working paper, 2009-07)
We study the relationship between competition and quality within a spatial competition framework where firms compete in prices and quality. We generalise existing literature on spatial price-quality competition along ...
Horizontal mergers and product quality
(Discussion paper;4/2014, Working paper, 2014-02)
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 ...
Reference pricing of pharmaceuticals
(Discussion paper2005:25, Working paper, 2005-11)
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 ...
Pharmaceutical patents : incentives for R&D or marketing?
(Discussion paper2005:22, Working paper, 2005-11)
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 ...
Quality competition with profit constraints : do non-profit firms provide higher quality than for-profit firms?
(Discussion paper2011:2, Working paper, 2011-02)
Hospital mergers : a spatial competition approach
(Discussion paper;8/2013, Working paper, 2013-04)
Using a spatial competition framework with three ex ante identical hospitals, we study the effects of a hospital merger on quality, price and welfare. The merging hospitals always reduce quality, but the non-merging hospital ...
Can competition reduce quality?
(Discussion paper;9/2012, Working paper, 2012-03)
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 ...
Hospital competition with soft budgets
(Discussion paper;6/2012, Working paper, 2012-03)
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 ...
Margins and market shares : pharmacy incentives for generic substitution
(Discussion paper2010:18, Working paper, 2010-07)
We study the impact of product margins on pharmacies incentive to promote generics instead of brand-names. First, we construct a theoretical model where pharmacies can persuade patients with a brand-name prescription to ...
