Damned If You Do and Damned If You Don’t: Two Masters

2018

Available online: 05 June 2018 We study common agency problems in which two principals (groups) make costly commitments to incentives that are conditioned on imperfect signals of the agent's action. Our framework allows for incentives to be either rewards or punishments. For our basic model we obtain a unique equilibrium, which typically involves randomization by both principals. Greater similarity between principals leads to more aggressive competition. The principals weakly prefer punishment to rewards, sometimes strictly. With rewards an agent voluntarily joins both groups with punishment it depends on whether severe punishments are feasible and cheap for the principals. We study whether…

Coordinated Punishment and the Evolution of Cooperation

2015

In this paper, we analyze a team trust game with coordinated Q1 punishment of the allocator by investors and where there is also a final stage of peer punishment. We study the effect of punishment on the reward and the investment decisions, when the effectiveness and cost of coordinated punishment depend on the number of investors adhering to this activity. The interaction takes place in an overlapping-generations model with heterogeneous preferences and incomplete information. The only long-run outcomes of the dynamics are either a fully cooperative culture (FCC) with high levels of trust and cooperation and fair returns or a non-cooperative culture with no cooperation at all. The basin of…

Blind justice: An experimental analysis of random punishment in team production

2010

We study the effect of blind punishment in a team production experiment, in which subjects choose non-observable effort levels. In this setting, a random exclusion mechanism is introduced, linked to the normalized group performance (R, from 0 to 1). Every round, each subject is non-excluded from the collective profit with probability R (and with probability 1 ! R gets no benefit from the group account). Punishment does not depend on the individual behavior, but the probability of being punished reflects collective performance. As the exclusion probability is computed at the group level, no individual information is needed to implement exclusion. However, the probabilistic punishment risks t…

Cooperation and Status in Organizations

2010

We report the results of experiments designed to test the effect of social status on contributions to a public good, with and without punishment. The experiments are conducted in four-person groups in a “star” network, where one central player observes and is observed by the others. This imposes a social structure on the game, and gives the central player a leadership role in the group, simply by virtue of being commonly observed. We further manipulate status by allocating the central position to the person who earns the highest, or the lowest, score on a trivia quiz. These high-status and low-status treatments are compared, and we find that the effect of organizational structure—the existe…

Trust and punishment

2021

Abstract This paper explores the impact of institutions on the evolution of preferences (culture) and on economic outcomes. Punishment institutions determine the capacity and the individual cost of punishing opportunistic behavior, while preferences are endogenous and can be influenced by a cultural transmission process that is conditioned by the existing punishment institutions. We investigate the interaction and evolution between the preferences for reciprocity or rewarding of the allocator and the preferences to punish hostile behaviour by the investor in a trust game with a costly punishment phase. Our main result provides a rationale for the existence of a strong positive relationship …

Transformative, interdisciplinary and intercultural learning for developing HEI students’ sustainability-oriented competences : a case study

2022

AbstractThe literature has produced relevant theoretical insights into pedagogical frameworks, tools and competences that would be best suited to teach sustainability at higher education (HE). This article contributes to such a discussion using a course on sustainability developed by us as a case study. Two research questions are tackled in this article: (1) How to empower students to address urban sustainability challenges through the inclusion of transformative, interdisciplinary and intercultural learning into the current HE system? (2) Which pedagogical tools can be used to develop students’ sustainability-oriented competences? To address the research questions, the case study consists …

The role of «perceived loss» aversion on credit screening: an experiment

2013

A major characteristic of credit markets is information asymmetry.To combat its problems, as credit rationing, principals can use a menu of contracts to screen clients with different risk level. We conduct a laboratory experiment to address an important question for such settings —does the framing of the offered menu of contracts interfere with the self-selection mechanism? The answer is yes. We find subjects' choices shift when the same (positive) outcomes of the same menu of contracts are presented in two different frames. Subjects exhibit loss aversion in their perception of the positive outcomes below the reference point, and self-selection fails to occur. Uno de los mayores problemas a…

Hydrothermal aging of carbon reinforced epoxy laminates with nanofibrous mats as toughening interlayers

2016

Electrospun mats have been applied as toughening interlayers in high performance carbon fiber epoxy composites. While the toughening mechanism exerted by the mat at the interface is the subject of several recent studies, no investigations are reported on the aging behaviour of laminates comprising these nanostructured elements. This work investigates the influence of the combined effect of water and temperature (90 °C) on laminates with Nylon 6,6 electrospun membranes placed either at the middle plane only or at each interlayer. The water-uptake behaviour is modelled by a two-stage diffusion model and compared with the behaviour of the neat resin and of the laminate without mats. Interestin…
