This paper provides evidence that local social interactions within etnic groups may explain the puzzling variations in labour-market outcomes across individuals. Peer effects work first by creating pressure on labor-market participation, second, by conveying information about job opportunities...

This paper proposes a new theory of social norms that explores the relation between individuals' income, time allocation decisions, and consumption choices on the one hand, and the determinants of individuals' decision to conform or not to social norms on the other. It is shown that rational...

We investigate the role of manipulation in a model of opinion formation where agents have opinions about some common question of interest. Agents repeatedly communicate with their neighbors in the social network, can exert some effort to manipulate the trust of others, and update their opinions...

This paper, on the one hand, goes a step closer to demonstrate the causality of social capital on economic performance. On the other hand, we confirm a continued role of social capital effects on economic performance in this paper by using a much larger sample, spanning three decades and...

This paper proposes a new formulation of the theory of social norms. The theoretical model explores the interrelation between individuals' income, time-use and consumption decisions on the one hand, and the determinants of their decision to conform or not to social norms on the other. It is...

We use laboratory experiments to investigate how employers develop social structures for sharing information about the trustworthiness of job candidates, when worker opportunism is possible. The experimental data show that substantial information sharing emerges. Two types of information...

This experimental study investigates how behavior changes after punishment for an unkind action. It also studies how fairness perceptions affect the reaction to punishment and whether this effect is consistent across repeated play and role experiences. A repeated version of the power-to-take...

A symmetric network consists of a set of positions and a set of bilateral links between these positions. Examples of such networks are exchange networks, communication networks, disease transmission networks, control networks etc. For every symmetric network we define a cooperative transferable...

There is increasing empirical and experimental evidence that providing financial incentives to agents to perform certain socially desirable actions may permanently reduce other types of motivations to undertake these actions. We study the impact of financial incentives on the desire for social...

Economists increasingly pay attention to social capital as an important determinant of macroeconomic growth performance. At the same time, there is discussion regarding the robustness of the results of empirical growth studies. In a seminal paper, Knack and Keefer (1997) assess the effect of...
