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).

The way in which agents manipulate the distribution of performance outcomes in strategic settings has received increasing attention in the game theory literature. This paper uses an evolutionary approach to examine the optimal adaptation of strategic variability in corporate promotion...

The purpose of this paper is to generalize the incomplete contract model of Bajari and Tadelis (2001) into a continuous model, and to derive the condition under which the monotone comparative statics (MCS) methods can be applied. I will show that a type of single-crossing condition on the...

Paper aims sustaining the necessity of adapting studying criteria to the analysed matter and to the times: to the knowledge based economy. It tries to be a proposal to look for profound causes of economic activity results. Methodologically, paper replaces earn marking by the criterion of the...

This study reports experimental market power and efficiency outcomes for a computational wholesale electricity market operating in the short run under systematically varied concentration and capacity conditions. The pricing of electricity is determined by means of a clearinghouse double auction...

In this paper I described group theoretic methods that can be used for analyzing the boundary problems, which arise when the Hamiltonian method is applied to solve the relaxed problem for the multidimensional screening problem. This technique can provide some useful insights into the structure...

In this paper I consider a model of coexisting moral hazard and adverse selection, similar to one considered by Guesnerie, Picard, and Rey (1989). I provide an explicit solution for the optimal incentive scheme in the case, when the effort is observed with a normally distributed error. The main...

We consider a general agency model with coexisting hidden action and hidden information. We prove that, with minor technical qualifications, independence of the production technology from the consumer type is necessary and sufficient for welfare irrelevance of hidden action. Our result clarifies...

In the research works, moral hazard is usually represented in two natural states (accident and no accident). In this case, the determination of the optimal contract could be made graphically. The mathematicaing is become more complicated when we consider infinite natural states and efforts under...
