This paper tests social identity theory with respect to individuals' self-identification behavior. We report results from a laboratory experiment in which subjects choose their group membership, which is interpreted as decision to identify with the respective group. Inducing a trade-off between...

We show theoretical and experimental results that demonstrate the potential of transparency to influence committee decision making and deliberation. We present a model in which committee members have career concerns and unanimity is needed to change the status quo. We study three scenarios -...

This paper examines how neutral the current EU decision-making procedures are to membership and how well they obey certain transparent general constitutional principles. The paper evaluates the performance of the procedures by strategic and classical power indices. The main emphasis in the...

Cerreia-Vioglio, Ghirardato, Maccheroni, Marinacci and Siniscalchi (Economic Theory, 48:341-375, 2011) have recently axiomatised preferences in the presence of ambiguity as Monotonic Bernoullian Archimedean (MBA) preferences. We investigate the problem of Arrovian aggregation of MBA preferences...

This paper studies the influence of interregional inequality within countries on internal conflicts. Regional inequalities are measured by the population-weighted coefficient of variation of regional GDP per capita. As the main innovation, I use a panel data set of country-level regional...

This paper shows how conflicting normative views of fair contribution rules can be used to design sequential contribution mechanisms to foster human cooperation in heterogeneous populations. Our model predicts that a sequential mechanism which solicits contributions first from wealthy actors...

We study the problem of assigning indivisible goods to individuals where each is to receive one object. To guarantee fairness in the absence of monetary compensation, we consider random assignments and analyse various equity criteria for such lotteries. In particular, we find that sd-no-envy (as...

We develop a quantitative framework in which income inequality arises endogenously in response to productivity shocks. The framework accommodates sectoral inputoutput linkages, arbitrary elasticities of factors and intermediates, and heterogeneous workers that endogenously choose to supply their...
