Uncertainty about renewable production increases the importance of sequential short-term trading. We consider a two-stage market where conventional and renewable producers compete in order to satisfy the demand of consumers. The trading in the first stage takes place under uncertainty about...

We study the impact of competition and environmental policy (feed-in tariff vs. the EU ETS) on investment, CO2 emissions and welfare in an electricity sector. We consider different market structures (a planner who maximises social welfare vs. duopoly) and two types of consumers (those whose...

This literature review analyses the impacts of the EU ETS on competitiveness focussing on existing simulation studies. We have identified the choice of the reference scenario as the most critical issue for an appropriate analysis of the relevant literature. We find, however, that effects of the...

We study the impact of competition and environmental policy (feed-in tariff vs. the EU ETS) on investment, CO2 emissions and welfare in an electricity sector. We consider different market structures (a planner who maximises social welfare vs. duopoly) and two types of consumers (those whose...

We study a reform by which a standardized model of choice and competition was introduced in tax-financed home care in a majority of Swedish municipalities. The market for home care is of particular interest since it is close to the ideal quasi-market. For identification, we exploit the different...

Hospital markets are often characterised by price regulation and the existence of different ownership types. Using a Hotelling framework, this paper analyses the effect of different objectives of the hospitals on quality, profits, and overall welfare in a price regulated duopoly with symmetric...

Hospital markets are often characterised by price regulation and the existence of different ownership types. Using a Hotelling framework, this paper analyses the effect of heterogeneous objectives of the hospitals on quality differentiation, profits, and overall welfare in a price regulated...

We investigate the effect of competition on quality in regulated markets (e.g., health care, higher education, public utilities), using a Hotelling framework, in the presence of sluggish demand. We take a differential-game approach, and derive the open-loop solution (providers choose the optimal...

New empirical evidence shows substantial heterogeneity in the altruism of healthcare providers. Spurred by this evidence, we build a spatial quality competition model with altruism heterogeneity. We find that more altruistic healthcare providers supply relatively higher quality levels and...

We study the equilibrium and its stability property in a duopoly market in which minimum quality standards (MQS) are set, prices are regulated with links to product quality, and firms compete in quality. The adjustment dynamics are taken into account. We focus on the role that MQS play, in...
