A monopolist is treated as a nexus of contracts with team production. It has one ownermanager. The owner-manager is the employer of two employees. A team production problem is present if the employer is a managerial lemon. If the team production problem is solved, the employer is a managerial...

In many intermediate goods markets buyers and sellers both have market power. Contracts are usually long-term and negotiated bilaterally, codifying many elements in addition to price. We model such bilateral oligopolies as a set of simultaneous Rubinstein-Ståhl bargainings over contracts...

A monopolist is treated as a nexus of contracts with team production. It has one ownermanager. The owner-manager is the employer of two employees. A team production problem is present if the employer is a managerial lemon. If the team production problem is solved, the employer is a managerial...

A well established belief both in the game-theoretic IO and in policy debates is that market concentration facilitates collusion. We show that this piece of conventional wisdom relies upon the assumption of profit-seeking behaviour, for it may be reversed when firms pursue other plausible goals....

This paper theoretically analyzes the role of reference prices on competition and welfare in a context of a circular city model with free entry and reference prices, in which paying market prices above a reference negatively affects the utility of consumers. Agents interact in a three-stage...

This survey presents in a historical way the main contributions to the hardcore theory of aggregative games and the applications of this model to several fields of economics, other social sciences and engineering.

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).

Agent-based Computational Economics (ACE) is the computational study of economic processesmodeled as dynamic systems of interacting agents. This essay discusses the potentialuse of ACE modeling tools for the study of macroeconomic systems. Points are illustratedusing an ACE model of a two-sector...
