Biased beliefs in search markets
Gamp, Tobias; Krähmer, Daniel - 2022
We study the implications of biased consumer beliefs for search market outcomes in the seminal framework due to Diamond (1971). Biased consumers base their search strategy on a belief function which specifies for any (true) distribution of utility offers in the market a possibly incorrect...

Beliefs and actions in the trust game : creating instrumental variables to estimate the causal effect
Costa-Gomes, Miguel A.; Huck, Steffen; Weizsäcker, Georg - 2012
In many economic contexts, an elusive variable of interest is the agent's belief about relevant events, e.g. about other agents' behavior. A growing number of surveys and experiments ask participants to state beliefs explicitly but little is known about the causal relation between beliefs and...

Cross-game learning and cognitive ability in auctions

We study experimentally to what extent cross-game learning can reduce overbidding in SPAs, taking into account …-game learning for cognitively less able participants but does not affect overbidding for the cognitively more able. Vice versa …, 'cross-game learning' may rather be understood as 'cross-game transfer', as it has the potential to benefit bidders with …

The power of sunspots : an experimental analysis
Fehr, Dietmar; Heinemann, Frank; Llorente-Saguer, Aniol - 2017
This paper presents an experiment on a coordination game with extrinsic random signals, in which we systematically vary the stochastic process generating these signals and measure how signals affect behavior. We find that sunspot equilibria emerge naturally if there are salient public signals....

Sunspots in global games : theory and experiment
Heinemann, Frank; Moradi, Homayoon - 2018
We solve and test experimentally a global-games model of speculative attacks where agents can choose whether to read, at a cost, a payoff irrelevant (sunspot) announcement. Assuming that subjects exogenously believe some others to follow sunspots, we provide conditions for a unique equilibrium...

Selling dreams : endogenous optimism in lending markets
Bridet, Luc; Schwardmann, Peter - 2020
We propose a simple model of borrower optimism in competitive lending markets with asymmetric information. Borrowers in our model engage in self-deception to arrive at a belief that optimally trades off the anticipatory utility benefits and material costs of optimism. Lenders' contract design...

Behavioral implementation without unanimity
Korpela, Ville; Lombardi, Michele; Zachariassen, Julius - 2024
Behavioral implementation studies implementation when agents' choices need not be rational. All existing papers of this literature, however, fail to handle a large class of choice behaviors because they rely on a well-known condition called Unanimity. This condition says, roughly speaking, that...

All Deceptions Are Not Alike: Bayesian Mechanism Design with Social Norm Against Lying
Korpela, Ville - 2014
We say that a society has a weak norm against lying if, all other things being equal, agents rather lie in such a way that they do not get caught. We show that if this is the case, and it usually is, then Bayesian monotonicity is no longer a constraint in implementation and all incentive...

Spin doctors : an experiment on vague disclosure
Deversi, Marvin; Ispano, Alessandro; Schwardmann, Peter - 2021
Unfavorable news are often delivered under the disguise of vagueness. Our theory-driven laboratory experiment investigates this strategic use of vagueness in voluntary disclosure and asks whether there is scope for policy to improve information transmission. We find that vagueness is profitably...
