We consider a multi-service transportation system in which passengers are heterogeneous along two dimensions, namely ideal departure time and value of time, leading to both horizontal and vertical differentiation. We investigate the behavior of passengers, and assess how service pricing and...

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...

The electricity sector is the largest source of greenhouse gases (GHG) emissions in the world, and reducing these emissions can often be costly. However, because electricity markets remain integrated at a shallow level (with different pricing regulations), many gains from deeper integration...

Budget balance cannot be achieved if rates depend upon individual agents' own consumption only, which we refer to as individualistic pricing. Thus, interdependence between agents should be accounted for, for example by taking total consumption into account explicitly

We study innovation timing and socially optimal intellectual property rights (IPRs) when firms facing market uncertainty invest strategically in product development. If demand growth and volatility are high, attrition occurs and IPRs should ensure the cost of imitation attains a lower bound we...

This paper surveys what can be learned from recent advances in the incomplete contract literature to understand how public goods are or should be provided. The paper starts with a section on the full information case that presents and discusses the classical Samuelson condition on the optimal...
