The recently formed French School of the “économie des conventions” have claimed that they are developing a revolutionary new approach to the social sciences. This group of researchers in economics, philosophy, sociology, law and history attempt to transcend the inherited analytical frameworks of structural-functionalist sociology and neoclassical economics and provide an alternative picture of the social world. This article will investigate some of these claims in detail. First, I trace the cohesion of the Convention School's ideas around the key concept (...) of convention. Conventionalist theory reflects an ontological shift towards the recognition of intersubjectivity. This shift leads to tension between the advocacy of methodological individualism on the one hand and the use of convention as a central analytical category on the other. (shrink)

This article focuses on the conventions that sustain social interaction and argues that they are central to Simon's decision-making theory. Simon clearly identifies two kinds of coordination by convention: behavioral mores that shape human actions, and shared mental models that govern human perceptions. This article argues that Poincaré–Carnap's conventionalism provides powerful support for Simon's theory; it contends that this theory offers a more convincing account of decision and coordination than Lewis' concept of convention. Simon's approach to applying conventionalist logic to (...) social interaction emphasizes the normative role played by mental models in solving coordination problems and considers rationality in terms of both cognitive and moral considerations. By connecting conventional phenomena to social identifications, Simon stresses the resulting complexity of coordination problems. (shrink)

A critique is not a matter of saying that things are not right as they are. It is a matter of pointing out on what kinds of assumptions, what kinds of familiar, unchallenged, unconsidered modes of thought, the practices that we accept rest.... Criticism is a matter of flushing out that thought and trying to change it: to show that things are not as self-evident as one believed, to see that what is accepted as self-evident will no longer be accepted (...) as such. Practicing criticism is a matter of making facile gestures difficult. Michel Foucault (1988b, 154). (shrink)

The problem of cooperation for rational actors comprises two sub problems: the problem of the intentional object (under what description does each actor perceive the situation?) and the problem of common knowledge for finite minds (how much belief iteration is required?). I will argue that subdoxastic signalling can solve the problem of the intentional object as long as this is confined to a simple coordination problem. In a more complex environment like an assurance game signals may become unreliable. Mutual beliefs (...) can then bolster the earlier attained equilibrium. I will first address these two problems by means of an example, in order to draw some more general lessons about combining evolutionary theory and rationality later on. (shrink)
