How should we make value judgments about wealth inequality? Harsanyi (1953) proposes to take an individual who evaluates her well-being by expected utility and ask her to evaluate the wealth possibilities ex-ante (i.e. before she finds her place in society, i.e., under the "veil of ignorance" of...

This work is based on a differential game proposed by Kelvin Lancaster. The game between two agents called workers and capitalists is based on the accumulation and redistribution of benefits among social classes concluding that cooperative outcomes outperform non-cooperative. This approach...

We provide a model of group sorting or polarization based on group identity alone. In our model, agents differ from one another in terms of a binary group identity. Groups may also differ in terms of the distribution of abilities, but the distribution of abilities by group is uncertain and both...

Inequity aversion models have been used to explain equitable payoff divisions in bargaining games. I show that inequity aversion can actually increase the asymmetry of payoff division if unanimity is not required. This is due to the analogy between inequity aversion and risk aversion. Inequity...

Inequity aversion models have been used to explain equitable payoff divisions in bargaining games. I show that inequity aversion can actually increase the asymmetry of payoff division in majoritarian bargaining games

This paper applies the indirect evolutionary approach to study the evolution of inequality aversion in a simplified game of life. The game comprises a dilemma, a problem of coordination, and a problem of distribution as a general framework for the evolution of preferences. In singlegame...

As a proxy for a Pareto-efficient market economy, we adopt the two-party Nash Bargaining model featuring a qualitative bias in the treatment of the contributions of the parties. The Piketty inequality here is the share in total welfare accruing to the richer party over total welfare attained at...

We prove that in a market where agents rank objects independently and uniformly at random, there exists an assignment of objects to agents with a constant average rank (i.e., an average rank independent of the market size). The proof builds on techniques from random graph theory and the FKG...

We propose a formal way to systematically study the differential effects of exogenous shocks in economic models with heterogeneous agents. Our setting applies to models that can be rephrased as "competition for market shares" in a broad sense. We show that even in presence of any number of...

This paper presents an experimental analysis of 2x2 coordination games in which player 1 earns a substantially higher payoff than player 2 except in the inefficient equilibrium where they earn the same payoffs. The main focus is on the comparison of two treatments with and without the ex post...
