This paper develops a new framework for studying multiproduct intermediaries when consumers demand multiple products and face search frictions. We show that a multiproduct intermediary is proÖtable even when it does not improve consumer search e¢ ciency. In its optimal product selection, it stocks...

We consider a strategic contest game in which risk-averse agents exert efforts to increase their share of a risky rent. We show that a unique symmetric equilibrium always exists under constant or decreasing absolute risk aversion. We also show that agents exert in general less efforts when they are...

Farming systems are complex structures with several dimensions interacting in a dynamic and continuousmanner around farmers' management strategies. This complexity peaks in semi-arid regions of India, where small farms encounter a highly competitive environment for markets and resources, especially...

What is the effect of introducing jury members in criminal courts? While surveys regularly point out a demand by citizens for harsher punishment, the differences between surveys’ and real decisions’ conditions are large enough to cast a doubt on the results. The introduction of two jurors into a...

A contingent valuation approach is used to estimate how households value different multipurpose infrastructures (conventional or green) for managing flood risk and water pollution. As a case study we consider the Gorla Maggiore water park located in the Lombardy Region, in Northern Italy. The park...

This paper shows that error bounds can be used as effective tools for deriving complexity results for first-order descent methods in convex minimization. In a first stage, this objective led us to revisit the interplay between error bounds and the Kurdyka-Lojasiewicz (KL) inequality. One can show...
