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...

Numeraire choice is often deemed a problem of purely analytical convenience. In this paper I show that there is more to numeraire selection than meets the eye for the formulation of monetary policy in countries with weak fiscal institutions. I show how (a) improper numeraire choice can...

In this paper I show that, just as with Nash Equilibrium, there are sparse 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...

Suppose we know the utility function of a risk averse decision maker who values a risky prospect X at a price CE. Based on this information alone I develop upper bounds for the tails of the probabilistic belief about X of the decision maker. I also illustrate how to use these expected utility...

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 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...

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'...

In this paper I study the El Farol problem, a deterministic, boundedly rational, multi-agent model of a resource subject to congestion externalities that was initially studied computationally by Arthur (1994). I represent the interaction as a game, compute the set of Nash equilibria in mixed...
