This paper studies the optimal price structure in the postal sector when worksharing is available (e.g., for collection, sorting and transportation). In particular, we compare the optimal worksharing discount to the ECPR discount. Classification JEL : L9, L51, L32

This paper studies the optimal structure of supply in the air-transportation industry. The impact of price regulation on quality is taken into account. It is shown that, at the first-best optimum, the generalised transportation price (ticket price + time costs) exactly equals the average costs....

Electricity markets vary greatly across jurisdictions, in terms of regulatory institutions, cost levels and environmental impacts. Integrating such different markets can lead to significant changes. This paper considers two jurisdictions - one with a regulated monopoly selling at average cost...

We study entry in a growing market by ex-ante symmetric duopolists when sunk costs differ for the innovating and imitating firm. Strategic competition takes the form either of a preemption race or of a war of attrition, the latter being likelier when demand uncertainty is high. Industry value is...

With the growing share of wind production, understanding its impacts on electricity price and greenhouse gas (GHG) emissions becomes increasingly relevant, especially to design better wind-supporting policies. Internal grid congestion is usually not taken into account when assessing the price...

We show that the standard analysis of vertical relationships transposes directly to investment dynamics. Thus, when a firm undertaking a project requires an outside supplier (e.g., an equipment manufacturer) to provide it with a discrete input to serve a growing but uncertain demand, and if the...

We propose a new climate policy that is efficient, robust, and asks for payments proportional to realized climate damage. In each period, countries are made liable for their share of the responsibility in the current damage. Efficiency follows from countries' anticipations of climate change,...
