Honesty and self-selection into cheap talk

Fehrler, Sebastian; Fischbacher, Urs; Schneider, Maik T. - In: The economic journal : the journal of the Royal … 130 (2020) 632, pp. 2468-2496

In many situations, people can lie strategically, for their own benefit. Since individuals differ with respect to their willingness to lie, the credibility of statements will crucially depend on who self-selects into such cheap-talk situations. We study this process in a two-stage political...

Buy now and pay (dearly) later : unraveling consumer financial spinning

Mesly, Olivier - In: International Journal of Financial Studies : open … 9 (2021) 4, pp. 1-21

In this challenging and innovative article, we propose a framework for the consumer behavior named "consumer financial spinning". It occurs when borrowers-consumers of products with high financial stakes accumulate unsustainable debt and disconnect from their initial financial hierarchy of...

Simple mediation in a cheap-talk game

Ganguly, Chirantan; Ray, Indrajit - In: Games 14 (2023) 3, pp. 1-14

In the Crawford-Sobel (uniform, quadratic utility) cheap-talk model, we consider a simple mediation scheme (a communication device) in which the informed agent reports one of the N possible elements of a partition to the mediator and then the mediator suggests one of the N actions to the...

Costly miscalibration

Guo, Yingni; Shmaya, Eran - In: Theoretical economics : TE ; an open access journal in … 16 (2021) 2, pp. 477-506

We consider a platform which provides probabilistic forecasts to a customer using some algorithm. We introduce a concept of miscalibration, which measures the discrepancy between the forecast and the truth. We characterize the platform's optimal equilibrium when it incurs some cost for...

Delegating learning

Escobar, Juan F.; Zhang, Qiaoxi - In: Theoretical economics : TE ; an open access journal in … 16 (2021) 2, pp. 571-603

Learning is crucial to organizational decision making but often needs to be delegated. We examine a dynamic delegation problem where a principal decides on a project with uncertain profitability. A biased agent, who is initially as uninformed as the principal, privately learns the profitability...

Intention or request : the impact of message structures

Wang, Siyu; Flannery, Timothy - In: Games 12 (2021) 1/12, pp. 1-13

This paper investigates how different message structures impact communication strategy as well as sender and receiver behavior. Specifically, we focus on comparing communication games with messages stating an intention versus a request. Our experimental results show that when a game includes...
