Using an exhaustive database on academic publications in mathematics, we study the patterns of productivity by world mathematicians over the period 1984-2006. We uncover some surprising facts, such as the absence of age related decline in productivity and the relative symmetry of international...

We analyze how uncertainty regarding future climate conditions affects the design of concession contracts, organizational forms and technological choices in a principal-agent context with dynamic moral hazard, limited liability and irreversibility constraints. The prospect of future, uncertain...

This article analyzes the effects of international trade policies on an imperfect competitive domestic market, taking into account not only consumers but also upstream and downstream firms. We first study the impact of a classic import tax decrease and we find that upstream firms are harmed and...

This paper constructs an economic analysis of some organ donation organizations. The two main examples are voluntary marrow donor registries and cord blood banks. The main characteristic of this system is to facilitate the graft of bone marrow or cord blood to patients. These grafts require a...

This paper proposes a game to study strategic communication on platforms by parties. Parties’ platforms have been chosen in a multidimensional policy space, but are imperfectly known by voters. Parties strategically decide the emphasis they put on the various issues, and thus the precision of...

We show that the standard analysis of vertical relationships transposes directly to investment timing. Thus, when a firm undertaking a project requires an outside supplier (e.g. an equipment manufacturer) to provide it with a discrete input, and if the supplier has market power, investment...

We consider electricity generation industries where thermal operators imperfectly compete with hydro operators that manage a (scarce) water stock stored in reservoirs over a natural cycle. We explore how the exercise of intertemporal market power affects social welfare and environmental quality....
