We study the competitive effects of restricting direct access to secondary care by gatekeeping, focusing on the informational role of gatekeeping general practitioners (GPs). We consider a secondary care market with two hospitals choosing the quality and specialisation of their care. GPs...

Aggregate shocks in demand such as the burst of the 2001 dot-com bubble affect firms’ behavior and, therefore, the market structure. This paper proposes a fully dynamic oligopoly model to evaluate the impact of aggregate demand shocks on entry and exit costs as well as on investment and labor...

We study effects of direct-to-consumer advertising (DTCA) in a market with two pharmaceutical firms providing horizontally differentiated (branded) drugs. Patients varying in their susceptability to medication are a priori uninformed of available medication. Physicians making the prescription...

We study the relationship between regulatory regimes and pharmaceutical firms’ pricing strategies using a unique policy experiment from Norway, which in 2003 introduced a reference price (RP) system called “index pricing” for a sub-sample of off-patent pharmaceuticals, replacing the...

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...

We analyse how a patent-holding (incumbent) firm may strategically use advertising ex ante to a¤ect the R&D investments in new (di¤eren- tiated) products, and thus the ex post market structure in the industry. We derive exact conditions for advertising and R&D being substitute strategies for...

While a growing literature examining the relationship between income and health expenditures suggests that health care is a luxury good, this conclusion is contentiously debated due to heterogeneity of the existing results. This paper tests the luxury good hypothesis using meta-regression...

We present a model of optimal contracting between a purchaser and a provider of health services when quality has two dimensions. We assume that one dimension of quality is veri?able (dimension 1) and one dimension is not verifiable (dimension 2). We show that the power of the incentive scheme...

In many countries, the social insurance system is under pressure from an ageing population. An increasing number of people are on sickness benefits and disability pensions in Norway. The general practitioner (GP) is responsible for assessing work capacity and issuing certificates for sick leave...

The right to equal treatment, irrespective of age, gender, ethnicity, socio-economic status and place of resident, is an important principle for several health care systems. A reform of the Norwegian hospital sector may be used as a relevant experiment for investigating whether centralization of...
