I generalize the work horse model of network competition (Armstrong,1998; Laffont, Rey and Tirole, 1998 a, b) to include income effects incall demand. Income effects imply that call demand depends also on the subscription fee, not only on the call price. In the standard case of differentiated...

We propose nuclear capacity auctions as a means to improve the incentives for investing in nuclear power. A properly designed auction allocates the license to the most efficient bidder; sells the license if and only if new nuclear power is socially optimal. In particular, capacity auctions open...

Green certificates are the main instrument for promoting renewable electricity (RES-E) in Sweden. But certificates cover only a limited share of total RES-E production. Under partial coverage, crowding out may arise whereby costly new RES-E replaces inexpensive old RES-E. Granting certificates...

I generalize the workhorse model of network competition to include income effects in call demand. Empirical work has shown call demand to increase signi ficantly with income. For any positive income effect, network operators prefer a termination rate above marginal cost if networks are...

The capacity of the transmission network determines the extent of integration of a multi-national energy market. Cross-border externalities render coordination of network capacity valuable. Is it then optimal to collect powers in the hands of a single regulator? Should a common system operator...
