We study road supply by competing firms between a single origin and destination. In previous studies, firms simultaneously set their tolls and capacities while taking the actions of the others as given in a Nash fashion. Then, under some widely used technical assumptions, firms set the same...

This paper studies the welfare consequences of a vertical merger that raises rivals costs when downstream competition is à la Cournot between firms with constant asymmetric marginal costs. The main result is that such a vertical merger can nevertheless improve welfare if it involves a...

The objective of this paper is to find out whether differences between the domestic permit allocation procedures of the Member States of the European Union (EU) will distort competition and lead to state aid in a European carbon trading market. This paper shows that it depends whether one takes...

Two firms produce different qualities at possibly different, constant marginal costs. They compete in quantities on a market where buyers only observe the average quality supplied. The model is a generalization of the standard Cournot duopoly, which corresponds to the special case where the two...

This paper reconciles the Cournot and Bertrand Models of oligopolistic competition, highlighting its weaknesses and giving an opinion thereafter. The pertinent question in this paper is why Cournot (1838) ignored the price and Bertrand (1883) ignored the quantity? From the review, the main...

A small open economy operates a carbon emission trading scheme and subsidizes green energy. Taking cap-and-trade as given, we seek to explain the subsidy as the outcome of a trilateral tug of war between the green energy industry, the black energy industry and consumers. With parametric...

A small open economy operates a carbon emission trading scheme and subsidizes green energy. Taking cap-and-trade as given, we seek to explain the subsidy as the outcome of a trilateral tug of war between the "green" energy industry, the "black" energy industry and consumers. With parametric...
