This paper studies models where the optimal response functions under consideration are non-increasing in endogenous variables, and weakly increasing in exogenous parameters. Such models include games with strategic substitutes, and include cases where additionally, some variables may be...

In the article, a model of oligopolistic (duopolistic) competition between two people smuggling syndicates is developed. I consider the Cournot and Stackelberg cases. First, the deterministic case is considered, where I show the conditions of profit maximisation for the syndicates. Then, a model...

The demographic database of Eurostat and of Us Census of Bureau are explored and the main facts are extracted and described. This paper is completely self-standing but is also part of a more general analysis dedicated to the functioning and sustainability of pay-as-you-go to finance the welfare...

This paper investigates the large and unexpected increase in cigarette prices that followed the 1997 Master Settlement Agreement (MSA). We integrate key features of rational addiction theory into a discrete-choice model of the demand for a differentiated product. We find that following the MSA...

In the framework Hotelling-Downs competition two players can freely choose a position along a one-dimensional market. We introduce restrictions of feasible strategies and analyze the consequences for players and consumers. In equilibrium players may minimally differentiate away from the center...

We investigate the dynamic relationship between advertising and product quality under duopolistic competition. By using a simplified vertical product differentiation model with voluntary advertising, we show that the firm with larger market share has a larger advertising share and that there is...
