摘要：Although much of the theoretical and applied literature involving decision under ambiguity works under the assumption of uncertainty aversion, experimental evidence suggests that it is not a universal behavioural trait. This paper introduces and axiomatises the family of a-UA (for a-Uncertainty Attitude) preferences: a simple extension of uncertainty averse preferences with a Hurwicz-style mixing coefficient, so as to admit a richer range of uncertainty attitudes. The parameters of the model a...

摘要：Personal information is shared extensively every day, particularly when competing for others' attention on online platforms. In this paper, we experimentally investigate the interaction of peer comparison and incentives as drivers to disclose potentially privacysensitive information. We find that information sharing is higher under incentives, and further increases under peer comparison. This effect is driven by those initially disclosing less, who additionally report feeling more compelled to...

摘要：The Fisher market is one of the most fundamental models for resource allocation. However, Fisher markets are less amenable for resource allocation settings when agents have additional linear constraints beyond the budget constraints of buyers and the capacity constraints of goods. Thus, in this work, we introduce a modified Fisher market, where agents may have additional linear constraints, and study the properties of the resulting equilibria. To set equilibrium prices, we introduce a budget-a...

摘要：Job scheduling on parallel machines is a well-studied singleton congestion game. We consider a variant of this game, arising in environments with strong competition. In a scheduling game with rank-based utilities (SRBG) the players are partitioned into competition sets, and the goal of every player is to perform well relative to its competitors. We show that SRBGs are significantly different from classical job-scheduling games, and that competition may lead to poor outcomes. An SRBG need not h...

摘要：This paper develops a model to investigate the interaction between collective decision making in voting and financial speculation. Protesting voters demand policy reforms by voting against the incumbent, but too many opposing votes result in an unfavorable outcome: a political regime change. Traders speculate on the change of the political regime. The size of the speculation informs voters about the electorate's composition, thereby influencing the outcome of the election. We find that, in equ...

摘要：We demonstrate in a laboratory experiment in which subjects play a two-player CournotTullock game over hundreds of periods of varying length that full accounts of subjects' learning requires the consideration of, both, 'period time' and 'physical time.'& COPY; 2023 Elsevier Inc.

摘要：We consider a model of social coordination and network formation where agents decide on an action in a coordination game and on whom to form costly links with. We explore the role of linking friction, where an agent cannot change all of her links simultaneously when choosing an alternative linking decision. Given linking friction, interaction structures are not fully flexible. We introduce a new solution concept of static equilibria, local Nash equilibria, and find that the set of local Nash e...

摘要：We consider large population supermodular games with pairwise interaction and a continuous strategy set. Our objective is to establish convergence of the logit dynamic in such games to logit equilibria. For this purpose, we apply the deterministic approximation approach, which interprets a deterministic dynamic as an approximation of a stochastic process. We first establish the closeness of this dynamic with a step-wise approximation. We then show that the logit stochastic process is close to ...

摘要：This paper studies the effect of introducing an option of delay in coordination games- that is, of allowing players to wait and then choose between the risk-dominant and payoff-dominant actions. The delay option enables forward-induction reasoning to operate, whereby a player's waiting and not choosing the risk-dominant action right away signals an intention to choose the payoff-dominant action later. If players have epsilon-social preferences- they help others if they can do so at no cost to ...
