Central banks often use certain concentration indices in their official reports to determine the degree of intensity of competition, of which the most common are the concentration ratio and the Herfindahl-Hirschman index. It is important to emphasize that when calculating the value of these...

This paper explores the impact of technological change on industry concentration and the underlying firm dynamics. In the agent-based model EURACE@Unibi I implement a paradigm shift in the technological frontier - a shift from a slow to a fast growing regime. The analysis shows that the...

The claim that the Darwinian paradigm of blind-variation-and-selective-retention can be generalized from the biological to the socio-cultural realm has often been questioned because of the critical role played by human purposeful design in the process of cultural evolution. In light of the issue...

Epistemic arguments play a significant role in Hayek's defense of market liberalism. His claim that market competition is a discovery procedure that serves the common good is a case in point. The hypothesis of the markets' efficient use of existing knowledge is supplemented by the idea that...

Each of n = 1 identical buyers (and m = 1 identical sellers) wants to buy (sell) a single unit of an indivisible good. The core predicts a unique and extreme outcome: the entire surplus is split evenly among the buyers when m n and among the sellers when m n; the long side gets nothing. We...

We solve for the optimal mechanism for selling two goods when the buyer's demand characteristics are unobservable. In the case of substitutable goods, the seller has an incentive to offer lotteries over goods in order to charge the buyers with large differences in the valuations a higher price...

A seller and a buyer bargain over the terms of trade for an object. The seller receives a perfect signal that determines the value of the object to both players, whereas the buyer remains uninformed. We analyze the infinite-horizon bargaining game in which the buyer makes all the offers. When...

There is a general presumption that social preferences can be ignored if markets are competitive. Market experiments (Smith 1962) and recent theoretical results (Dufwenberg et al. 2008) suggest that competition forces people to behave as if they were purely self-interested. We qualify this view....

Market competition is central to innovative activity, the diffusion process and macro-economic productivity growth. Productivity growth at all levels comes about through institutional reconfiguration in response to the ongoing market process. Stable and sustained long-term growth in output...
