We determine the optimal health policy mix when the average utility of patients increases with the supply of drugs available in a therapeutic class. Health risk coverage rely on two instruments, copayment and reference pricing, that affect the supported risk composed by health expenses and...

Der Telekommunikationssektor ist diejenige Netzindustrie, die innerhalb der Europäischen Union dem wohl ambitioniertesten Reformprozeß unterworfen wurde. Deregulierung und Privatisierung sind die wesentlichen Bausteine, von denen dauerhaft niedrigere Preisniveaus, beschleunigter technischer...

This paper analyzes Influence Peddling with interaction between human capital transfer and collusion-building aspects in a model, in which each government official regulates multiple firms simultaneously. We show that (i) there exists an optimal division rule for collusion between a sequence of...

Nonparametric efficiency analysis has become a widely applied technique to support industrial benchmarking as well as a variety of incentive-based regulation policies. In practice such exercises are often plagued by incomplete knowledge about the correct specifications of inputs and outputs....

We show how size-contingent laws can be used to identify the equilibrium and welfare effects of labor regulation. Our framework incorporates such regulations into the Lucas (1978) model and applies this to France where many labor laws start to bind on firms with exactly 50 or more employees....

Since the 1990s, efficiency and benchmarking analysis has increasingly been used in network utilities research and regulation. A recurrent concern is the effect of environmental factors that are beyond the influence of firms (observable heterogeneity) and factors that are not identifiable...

This paper considers the supplier's strategic delivery lead time in a public procurement setting as the result of the firm's opportunistic behaviour on the optimal investment timing. In the presence of uncertainty on construction costs, we model the supplier's option to defer the contract's...

In order to increase efficiency in the provision of power distribution networks, the German regulator Bundesnetzagentur plans to implement revenue cap regulation together with yardstick competition. Revenue cap regulation could bear the ratchet effect: cost minimization need not to be optimal...

Imposing a minimum quality standard (MQS) is conventionally regarded as harmful if firms compete in quantities. This, however, ignores its possible dynamic effects. We show that an MQS can hinder collusion, resulting in dynamic welfare gains that reduce and may outweigh the static losses which...
