Empirical evidence shows that low cost of signaling interest in offers can result in a significant number of inappropriate signals. This paper provides a theoretical explanation for this observation as an equilibrium outcome of a model with utility maximizing fully rational agents that decide to...

I show that whether participants generally believe in others’ preference stability is a crucial determinant of behaviour. Whether a participant’s behaviour can be predicted by her best-response or a Nash-equilibrium in a context where she can observe others' elicited preferences depends...

We study investments in R&D and the formation of R&D clusters of firms which are competitors in the market. Firms first decide on long-term R&D investment, then form research clusters according to the unanimity game, and finally compete in quantities. Equilibria with no-investment might co-exist...

We consider the problem of a principal who wishes to contract with a privately informed agent and is not able to commit to not renegotiating any outcome of any mechanism. We provide a general characterization of renegotiation-proof outcomes. We apply the solution to a setting with a continuous...

We consider a game of information transmission, with one informed decision maker gathering information from one or more informed senders. Private information is (conditionally) correlated across players, and communication is cheap talk. For the one sender case, we show that correlation...

We study the formation of networks in environments where agents derive benefits from other agents directly linked to them but suffer losses through contagion when any agent on a path connected to them is hit by a shock. We first consider networks with undirected links (e.g. epidemics,...

We study strategic games where players' preferences are weak orders which need not admit utility representations. First of all, we ex- tend Voorneveld's concept of best-response potential from cardinal to ordi- nal games and derive the analogue of his characterization result: An ordi- nal game...

Contests are a common method to describe the distribution of many different types of rents. Yet in many of these situations the utilisation of the prize plays an important role in determining agents payoffs and incentives. In this paper, we investigate the incentives to expend effort for a prize...

We consider a class of perfect information bargaining games with unanimity acceptance rule. The proposer and the order of responding players are determined by the state that evolves stochastically over time. The probability distribution of the state in the next period is determined jointly by...

In non-cooperative bargaining games in the tradition of Rubinstein, the proposer derives bargaining power from the prospect of a costly delay which would follow the rejection of a proposal. We consider a unanimity bargaining game in which the proposer can strategically choose to prolong this...
