We reconsider Rosen’s economics of superstars model establishing, in the case of single-type consumers, a constant price-to-quality ratio. Rosen also conjectured that, in the case of multiple-type consumers, the normal course of consumer behavior forces the price-to-quality relationship to be...

We address the questions of the patterns and the efficiency of public intervention in a dynamic game model between public agencies in charge of a non-local externality. We give two examples: pollution spreading between water basins (negative externality), and non-uniform contributions from the...

The debate about whether the arts should be supported or not is far from being recent, and most governments support the arts in one way or the other. The literature considers several arguments in favor of such interventions. Education may seem as an action which could, in the long run, lead to...

We construct a two-periods OLG model in which households produce domestically a non-observable and transmissible commodity: "household culture" using cultural goods and transmitted culture as inputs. Parents fail to internalise the effect of unvoluntarily transmitted culture on their children's...

We introduce a new allocation rule, called the sequential equal surplus division for rooted forest TU-games. We provide two axiomatic characterizations for this allocation rule. The first one uses the classical property of component efficiency plus an edge deletion property. The second...

We investigate assignment of heterogeneous agents in trees where the allocation rule is given by the permission value. We focus on efficient hierarchies,namely those, for which the payoff of the top agent is maximized. For additive games, such hierarchies are always cogent, namely, more...
