In many business transactions, in labor-management relations, in international conflicts, and welfare state reforms bargainers hold strong entitlements that are often generated by claims that are not feasible any more. These entitlements seem to considerably shape negotiation behavior. By using the novel setup of a ‘bargaining with claims’ experiment we provide new systematic evidence tracking ...

Optimal Incentive Contracts under Inequity Aversion We analyze the Moral Hazard problem, assuming that agents are inequity averse. Our results differ from conventional contract theory and are more in line with empirical findings than standard results. We find: First, inequity aversion alters the structure of optimal contracts. Second, there is a strong tendency towards linear sharing rules. Thi...

This paper studies whether psychological considerations can prevent agents from adopting potentially Pareto improving innovations. In the innovation game without the sharing option, A chooses whether to introduce an innovation that increases A’s payoff, but reduces B’s payoff, relative to “status quo” payoffs. B then decides whether to accept or reject the innovation. The unique subgame perfect...

In this note we study von Neumann-Morgenstern farsightedly stable sets for Shapley and Scarf (1974) housing markets. Kawasaki (2008) shows that the set of competitive allocations coincides with the unique von Neumann-Morgenstern stable set based on a farsighted version of antisymmetric weak dominance (cf., Wako, 1999). We demonstrate that the set of competitive allocations also coincides with t...

The incompatibility between the Pareto indifference criterion and a concern for greater equality in living standards of heterogenous populations (see, amongst others, Ebert, 1995, 1997, Ebert and Moyes, 2003 and Shorrocks, 1995) might come as a surprise, since both principles are reconcilable when people differ only in income (homogenous population). We present two families of welfare rankings ...

There exist congenital diseases that reduce newborns' potential opportunities. This reduction is sometimes alleviated if the congenital disease is early detected thanks to a newborn screening program. We propose an outcome measurement of newborn screening programs based on the opportunity gains they offer after its implementation. We show that, under plausible assumptions, preferences among the...

We study the problem of allocating a bundle of perfectly divisible private goods from an axiomatic point of view, in situations where compensations can be made through monetary transfers. The key property we impose on the allocation rule requires that no agent should be able to gain by decomposing the problem into sequences of subproblems. Combined with additional standard properties, it leads ...

Organizations, Diffused Pivotality and Immoral Outcomes This paper studies how organizational design affects moral outcomes. Subjects face the decision to either kill mice for money or to save mice. We compare a Baseline treatment where subjects are fully pivotal to a Diffused-Pivotality treatment where subjects simultaneously choose in groups of eight. In the latter condition eight mice are ki...

We propose a multivariate extension of Yaari’s dual theory of choice under risk. We show that a decision maker with a preference relation on multidimensional prospects that preserves first order stochastic dominance and satisfies comonotonic independence behaves as if evaluating prospects using a weighted sum of quantiles. Both the notions of quantiles and of comonotonicity are extended to the ...

The dispute over the extent of global poverty hinges mostly on the disparity between household surveys and the national accounts estimates. In this paper we use data from the provinces of China to document the extent of this disparity in a major contributor to global poverty. JEL Classification number: O1, C80.
