Various approaches used in Agent-based Computational Economics (ACE) to model endogenously determined interactions between agents are discussed. This concerns models in which agents not only (learn how to) play some (market or other) game, but also (learn to) decide with whom to do that (or not).

This paper develops a simple model to examine the interaction between partner choice and individual behavior in games of coordination. An important ingredient of our approach is the way we model partner choice: we suppose that a player can establish ties with other players by unilaterally...

I study intermediation in a buyer-seller network with sequential bargaining. An intermediary matches traders connected in a network to bargain over the price of heterogeneous goods and has the freedom to charge each side commission. A profit-maximizing middleman can help eliminate trading delays...

The paper presents a simulation of the dynamics of impersonal trust. It shows how a 'trust/reciprocation' norm can emerge and stabilize in populations of conditional cooperators. The norm, or behavioral regularity, is not to be identified with a single strategy. It is instead supported by...

In this note we sketch a dynamic framework within which the discussion on the macroeconomic effects of climate change take place. The problem setting is characterized by scientific uncertainties about the development of climate, potential large economic losses and human beings having their...
