This paper characterizes the set of equilibrium networks in the two-way flow model of network formation with small decay, and this for all increasing benefit functions of the players. We show that as long as the population is large enough, this set contains large- as well as small-diameter...

The set of equilibrium networks in the two-way flow model of network formation (Bala and Goyal, 2000) is very sensitive to the introduction of decay. Even if decay is small enough so that equilibrium networks are minimal, the set of equilibrium architectures becomes much richer, especially when...

Abstract It is well-known in the IO literature that incumbent firms may want to deter entry by behaving as if they are efficient. In this paper we show that incumbents may sometimes prefer to encourage entry by mimicking the behaviour of a less efficient firm for the following reason. If the...

This paper analyzes consumers' choices between, as well as behavior within three selling mechanisms which are frequently used in online marketplaces: posted prices, ascending auctions and Buy-It-Now auctions. In an exploratory experiment, where subjects choose between one mechanism and an...

This paper considers a multi-player stag hunt where players are either available for action or not, and where players additionally differ in their degree of conservatism, i.e. in the threshold of players that need to act along with them before they see benefits in collective action. Minimal...

Public procurement contracts require frequent renegotiation. We exploit the Czech implementation of an EU policy as a natural experiment to investigate the effect of eased renegotiation rules. We document that the eased renegotiation rules decreased winning bids but did not change the final...
