This paper examines social interactions when social networking is endogenous. It employs a linear-quadratic model that accommodates contextual e®ects, and endogenous local inter- actions, that is where individuals react to the decisions of their neighbors, and endogenous global ones, where...

We study individually optimized continuous outcomes in a dynamic environment in the presence of social interactions, and where the interaction topology may be either exogenous and time varying, or endogenous. The model accommodates more general social effects than those of the mean-field type....

Empirical studies of labor markets show that social contacts are an important source of job-related information [Ioannides and Loury (2004)]. At the same time, wage differences among workers may be explained only in part by differences in individual background characteristics. Such findings...

We develop an empirical discrete-choice interaction model with a finite number of agents. We characterize its equilibrium properties-in particular the correspondence between interaction strength, number of agents, and the set of equilibria-and propose to estimate the model by means of simulation...

The role of anonymity in giving is examined in a field experiment performed in thirty Dutch churches. For a period of 29 weeks, the means by which offerings are gathered is determined by chance, prescribing for each offering the use of either 'closed' collection bags or open collection baskets....

In the Dutch Postcode Lottery a postal code (19 households on average) is randomly selected weekly, and prizes –consisting of cash and a new BMW-- are awarded to lottery participants living in that postal code. On average, this generates a temporary, unexpected income shock equal to about...
