We consider a model with two firms operating their individual networks. Each firm can choose its price as well as its investment to build up its network.

While access regulation imposed on the dominant firm leads to lower prices, positive welfare effects are diminished ...

However, it is remarkable that, for the accession ...

The relationship between international gas market prices and their relation to the oil price are explored through principal components analysis and Johansen likelihood-based cointegration procedure. Both of them show a high level of natural ...
