The opportunity to tell a white lie (i.e., a lie that benefits another person) generates a moral conflict between two opposite moral dictates, one pushing towards telling always the truth and the other pushing towards helping others. Here we study how people resolve this moral conflict. What...

We investigate experimentally whether players deliberately use irrelevant market cues to shape their evaluations of a traded item. We implement a repeated Vickrey median price selling auction of an unusual bad where players are informed on the market price and on the three lowest or highest...

The paper enriches a standard signaling model of education with issues of social distance defined over educational achievements. More specifically it considers the effects that the presence of conformist and status seeking individuals has on educational dynamics. Under very reasonable...

In many European countries the average level of education has grown steadily over the last few generations. The paper shows how such a trend can be easily rationalized by a model that extends a standard signalling game in two directions. First, a temporal structure is induced by having two...

We study the coevolution of cooperation, preferences, and cooperative signals in an environment where individuals engage in a signaling-extended prisoner's dilemma. We prove the existence of a cooperative equilibrium constituted by a (set of) limit cycle(s) and stabilized by the dynamic...

This paper provides a general analysis of signaling under double-crossing preferences with a continuum of types. There are natural economic environments where the indifference curves of two types cross twice, such that the celebrated single-crossing property fails to hold. Equilibrium exhibits a...

A general framework is developed for studying screening in many-agent discrete type environments wherein each agent's preferences depend endogenously on the allocations received by the other agents. Applications include optimal income taxation, performance contracting with across-worker...

The class of double-crossing preferences, where signaling is cheaper for higher types than for lower types at low signaling levels and the opposite is true at high signaling levels, underlines the phenomenon of countersignaling. We show that under the D1 refinement, the equilibrium signaling...
