In this note I study Nash bargaining when the utility possibility set of the bargaining problem is not-convex. A simple variation of Nash's Symmetry axiom is all that is necessary to establish a set-valued version of Nash's solution in non-convex settings

In this paper I present conditions, not involving common knowledge of rationality, that lead to (correlated) rationalizability. The basic observation is that, if the actual world belongs to a set of states where the set Z of action profiles is played, everyone is rational and it is mutual...

When evaluating the rationality of a player in a game one has to examine counterfactuals such as "what would happen if the player were to do what he does not do?" In this paper I develop a model of a normal form game where counterfactuals of this sort are evaluated as in the philosophical...

The distribution of firms' growth and firms' sizes is a topic under intense scrutiny. In this paper we show that a thermodynamic model based on the Maximum Entropy Principle, with dynamical prior information, can be constructed that adequately describes the dynamics and distribution of firms'...

This paper provides a solution to Proebsting’s Paradox, an argument that appears to show that the investment rule known as the Kelly criterion can lead a decision maker to invest a higher fraction of his wealth the more unfavorable the odds he faces are and, as a consequence, risk an...

Can a heterodox economist find arguments in favor of Central Bank independence? Economists currently favor arguments in favor of Central Bank independence based on Barro-Gordon (1983 a,b), a very ‘orthodox' model. Consequently, those who view the economic orthodoxy with suspicion tend to...

In 2010 the UNDP unveiled a new methodology for the calculation of the Human Development Index (HDI). In this paper I investigate the normative and practical properties of this change vis a vis the original formulation of the HDI in 1990. The main conceptual innovation of the new index can be...

What if it could be possible to convince a completely non-neoclassical economist of the importance of Central Bank independence? The profession currently favors arguments in favor of Central Bank independence that are based on the seminal work by Barro and Gordon (1983 a,b), a model with...

Consider a two player game that is to be played once. The players receive information that they use to help them predict the choices made by each other. A decision rule for each player captures how each player uses the information received in making their choices. Priors in this context are...
