This chapter explores the potential advantages and disadvantages of Agent-based Computational Economics (ACE) for the study of economic systems. General points are concretely illustrated using an ACE model of a two-sector decentralized market economy. Six issues are highlighted: Constructive...

This contribution focuses on the simulation of the emergence and evolution of communities of practice, a concept brought forwards originally in sociology in the early 90’s by Lave and Wenger (1990) and Brown and Duguid (1991). In a first part, the main theoretical principles on which relies...

We study learning in perfect competition. A price-taking firm sells a good whose quality is unknown to some buyers. The uninformed buyers use the price to infer information about quality. The presence of noise on the supply prevents perfect learning. Even though the firm is a price-taker,...

We study learning in perfect competition. A representative price-taking firm sells a good whose quality is unknown to some buyers. The uninformed buyers use the price to infer information about quality. Even though the firm is a price-taker, information is disseminated though the price. It is...

Through a series of decision tasks involving colored cards, we provide separate measures of Bayesian updating and non-probabilistic reasoning skills. We apply these measures to (and are the first to study) a common-value Dutch auction. This format is more salient than the strategically...

We report an experimental test of alternative rules in innovation contests when success may not be feasible and contestants may learn from each other. Following Halac et al. (forthcoming), the contest designer can vary the prize allocation rule from Winner-Take-All in which the first successful...

We study firms' incentives to acquire private information on cost in a duopoly signaling game. Firms first choose how much to invest in information acquisition and then engage in dynamic price competition. In equilibrium firms acquire too little information from the perspective of industry...

Early consumption of a product often benefits later consumers by revealing quality information. Inefficiency arises, however, because early consumers do not internalize the social value of their consumption. How could a platform that intermediates information between early and late consumers...

This paper investigates the effect of spillovers in a model of endogenous technical change resulting from learning or network effects on the existence of a lower bound to market concentration.
