We adapt the model of comparisons of experts initiated by Lehrer (“Comparison of experts JME 98”) to a context of uncertainty which cannot be modelised by expected utility. We examine the robustness of Lehrer in this new context. Unlike expected utility, there exist several ways to define...

Evolutionary approaches of the firm devote a part of their analysis to firm behavior and to some processes acting inside the firm, however the internal workings of firms are, most of the time, not deeply analyzed. In this perspective, this paper attempts to investigate whether " we can drop...

We demonstrate that no set of neutral and different social choice correspondences exists, so that, if proposed to a group of individuals, it leads to a uniquely defined society, stable in an intuitive sense. Weakening this latter condition makes it possible to reintroduce possibility. This...

In a standard stylised frame derived from Diamond Dybvig, banks operate within a network of debt contracts. Working in network enables banks to decentralize a Pareto Optimal allocation while it is impossible if banks operate in isolation. However, this outcome depends on the architecture of the...

This paper gives estimates of sectoral markup trends in thirteen OECD countries over the last three decades. It concludes with a slight, albeit heterogeneous, increase in price-cost margins (PCMs) overall, contrary to the generally expected effect of increased competition. More strikingly, it...

A conjecture of Laffer, which had considerable influence on fiscal doctrine, is that tax revenues of a Leviathan state eventually decrease when the tax rate exceeds a threshold value. We conduct a real effort experiment, in which a "worker" is matched with a non-working partner, to elicit the...
