In human societies, overcoming incentives to act selfishly is immensely important so as to promote prosocial behaviours. Social norms and relational utility, utility generated by such feelings as guilt, are mechanisms by which cooperation and coordination can be facilitated. Here we add...

The principal focus in the substantial literature on impediments to economic development has been on the inadequacies of policies and governance. However, successful economic development requires effectiveness of markets and incentives for investment, which in turn require trust. This paper...

Decline and break-up of institutionalized cooperation, at all levels, has occurred frequently. Some of its concomitants, such as international migration, have become topical in the globalized world. Aspects of the phenomenon have also become known as failing states. However, the focus in most...

Social norms permeate society across a wide range of issues and are important to understanding how societies function. In this paper we concentrate on 'bad' social norms - those that are inefficient or even damaging to a group. This paper explains how bad social norms evolve and persist; our...

People use moral wiggle room to behave selfish. But does a narrow wiggle room necessarily produce better social outcomes? When people disagree on normative goals, economic theories of self-image predict that narrowing the moral wiggle room will make choices not only less selfish but also even...

Mancur Olson and Robert Putnam provide two conflicting views on the effect of involvement with voluntary associations on their members. Putnam argues that associations instill in their members habits of cooperation, solidarity and public spiritedness. Olson emphasizes the tendency of groups to...

In public good games, voluntary contributions tend to start off high and decline as the game is repeated. If high contributors are matched, however, contributions tend to stay high. We propose a formalization predicting that high contributors will self-select into groups committed to charitable...

We analyze a coordination game characterised by varying degrees of conflict of interest, incentive to coordinate and information asymmetry. The primary objective is to question whether endogenous leadership better enables coordination. A secondary objective is to question whether preference and...

We consider a model of conformity that permits a non-conformist equilibrium and multiple conformist equilibria. Agents are assumed to behave according to a best reply learning dynamic. We details the conditions under which a social norm and conformity emerge. The emergence of conformity depends...

We report the results of a combination of a dictator experiment with either a "social planner" or a "veil of ignorance" experiment. The experimental design and the analysis of the data are based on the theoretical framework proposed in the companion paper by Becker, Häger, and Heufer (BHH,...
