The pump storage technique allows the use of cheap thermal electricity at periods of low demand to restore water resources that can be used to generate electricity at periods of peak demand. When the thermal plant and the hydro plant are managed by the same operator, the two plants are used in...

The paper analyzes the interaction between a reliable source of electricity production and intermittent sources such as wind or solar power. We first characterize the first-best dispatch and investment in the two types of energy. We put the accent on the availability of the intermittent source...

Intellectual property rights are legal constraints that limit conditions of entry in industries where incumbents are innovators. The set of legal constraints is the same for all industries, and there is no consideration of the possibility that the externalities created by entry in a given...

Efficiency in the management of electricity transmission networks is essential for the success of the liberalized energy markets. The paper is dedicated to the short-run management problems of these natural monopolies. It analyses how to organize and price access to and use of the transport...
