We present GeoXp, an R package implementing interactive graphics for exploratory spatial data analysis. We use a data basis concerning public schools of the French Midi-Pyréenées region to illustrate the use of these exploratory techniques based on the coupling between a statistical graph and...

I show that cutting the flow of information between a principal and an agent can increase the power of the incentives of the agent to reveal private information.

Following the IPCC's report (2005), which recommended the development and the use of carbon capture and sequestration (CCS) technologies in order to achieve the environmental goals, defined by the Kyoto Protocol, the issue addressed in this paper concerns the optimal strategy regarding the...

I develop a model of reciprocal altruism which accounts for some evidence in contracting situations, which are paradoxical from the point of view of neoclassical contract theory with selfish actors. My model predicts the crowding-out effect, observed in the Trust Game with the possibility of a...

This paper analyzes the rationale for the submission of hidden limit orders, and compares opaque and transparent limit order books. In my sequential model, the limit order trader may be informed with some probability. Both informed and large uninformed liquidity suppliers submit hidden orders in...

This paper reexamines the question of how to explain business cycle co-movements within and between countries. First, we present two simple theoretically flexible price models to illustrate how and why news shocks can generate robust positive co-movements in economic activity across countries....
