We examine a chain of sequential losses: an agent causes a loss to another, which triggers a loss to a third, and so forth. Our objective is to redistribute the losses fairly, taking into account that the chain turns "victim" to "injurer" in its subsequent step. This opens up for many...

When losses caused by one agent onto another triggers losses to a third, "victim" turns into "injurer" in the chain's subsequent steps. Should agents be responsible for the direct loss they cause or also bear some of the indirect losses they trigger? Through an axiomatic approach, we...

The paper analyzes quantity competition in economies in which a network describes the set of feasible trades. A model is presented in which the identity of buyers, of sellers, and of intermediaries is endogenously determined by the trade flows in the economy. The analysis first considers small...

A buyout option enhances an auction by allowing a bidder to purchase the item at a pre-specified price (instead of attempting to obtain the item by way of auction). A comparison is made between the ex ante welfare of bidders in an auction with a buyout option to a traditional auction with no...

What are the welfare effects of the information contained in macroeconomic statistics, central-bank communications, or news in the media? We address this question in a business-cycle framework that nests the neoclassical core of modern DSGE models. Earlier lessons that were based on "beauty...

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).

Economies are complicated systems encompassing micro behaviors, interaction patterns, and global regularities. Whether partial or general in scope, studies of economic systems must consider how to handle difficult real-world aspects such as asymmetric information, imperfect competition,...

We study dynamic price competition between sellers offering differentiated products with limited capacity and a common sales deadline. In every period, firms simultaneously set prices, and a randomly arriving buyer decides whether to purchase a product or leave the market. Given remaining...
