This study investigates mechanisms of tie formation in an interorganizational network generated by the mobility of employees between organizations. We analyze a data set that contains information on all organizations in the Stockholm metropolitan area between 1990 and 2003. We show that the...

The conditions under which young workers find their first real post-graduation jobs are both very important for the young's future careers and insufficiently known given their public policy implications. To study these conditions, and in particular the role played by networks, we use a Swedish...

In this paper we apply agent-based methodology on an issue that is fundamental for economic prosperity and growth: the diffusion of innovations. The diffusion of innovations is one of the topics where agent-based simulation is an extremely fruitful method allowing not only the observation of...

Using a simple computational model, we study consequences of herding behavior in population of agents connected in networks with different topologies: random networks, small-world networks and scale-free networks. Agents sequentially choose between two technologies using very simple rules based...

A migration network is modeled as a mutually beneficial cooperative agreement between financially-constrained individuals who seek to finance and expedite their migration. The cooperation agreement creates a network: established migrants contract to support the subsequent migration of others in...

This paper studies network formation in settings where players are heterogeneous with respect to benefits as well as the costs of forming links. Our results demonstrate that centrality, center-sponsorship and short network diameter are robust features of equilibrium networks. We find that in a...

This paper evaluates the strength of social and economic forces that affect the pressure to emigrate 'out of Africa' for four distinctly different African countries (Morocco, Egypt, Senegal and Ghana). In general, great expectations about attaining a higher living standard and expected low job...

This paper empirically explores relations between network positions in knowledge networks andtrust. In social network theory the closure argument and the gossip argument describe thisrelation. These two arguments do not distinguish between different dimensions of trust. In thispaper we estimate...

A fundamental question in social sciences is how trust emerges. We provide an answer which relies on the formation of social and economic relationships. We argue that behind trust lies the fact that individuals invest in connections taking into account the potential externalities networks...
