Incomplete and Asymmetric Surplus Information in Labor Relations
Numerous laboratory experiments show that workers reciprocate to high wages with high effort, when there is perfect information on the surplus created. Recent field experiments, however, suggest that trust and reciprocity may be lower or absent when the information is incomplete.We report a laboratory experiment with symmetric and asymmetric incomplete surplus information in a bilateral gift exchange setting.We find that trust and reciprocity have a significant positive effect on wages, effort and efficiency.But, all three are substantially lower under incomplete than under complete information.The negative impact on wages and efficiency is even greater with information asymmetry.incomplete information;industrial relations;trusts;efficiency

Collusion under Yardstick Competition: An Experimental Study
The effectiveness of relative performance evaluation schemes, such as yardstick competition, can be undermined by collusion.The degree to which the regulated agents manage to collude will be affected by the particulars of the scheme.We hypothesize that in a repeated game setting schemes will be more prone to collusion the smaller are the rents to the agents in case they behave non-cooperatively.We illustrate the relevance of this hypothesis by means of an economic experiment in which we compare the efficiency of two performance evaluation schemes.performance evaluation;competition;efficiency;games;collusion;yardstick

Moral punishment in everyday life
The present research investigated event-related, contextual, demographic, and dispositional predictors of the desire to punish perpetrators of immoral deeds in daily life, as well as connections among the desire to punish, moral emotions, and momentary well-being. The desire to punish was reliably predicted by linear gradients of social closeness to both the perpetrator (negative relationship) and the victim (positive relationship). Older rather than younger adults, conservatives rather than people with other political orientations, and individuals high rather than low in moral identity desired to punish perpetrators more harshly. The desire to punish was related to state anger, disgust, and embarrassment, and these were linked to lower momentary well-being. However, the negative effect of these emotions on well-being was partially compensated by a positive indirect pathway via heightened feelings of moral self-worth. Implications of the present field data for moral punishment research and the connection between morality and well-being are discussed.

Sustainable institutionalized punishment requires elimination of second-order free-riders
Although empirical and theoretical studies affirm that punishment can elevate
collaborative efforts, its emergence and stability remain elusive. By
peer-punishment the sanctioning is something an individual elects to do
depending on the strategies in its neighborhood. The consequences of
unsustainable efforts are therefore local. By pool-punishment, on the other
hand, where resources for sanctioning are committed in advance and at large,
the notion of sustainability has greater significance. In a population with
free-riders, punishers must be strong in numbers to keep the "punishment pool"
from emptying. Failure to do so renders the concept of institutionalized
sanctioning futile. We show that pool-punishment in structured populations is
sustainable, but only if second-order free-riders are sanctioned as well, and
to a such degree that they cannot prevail. A discontinuous phase transition
leads to an outbreak of sustainability when punishers subvert second-order
free-riders in the competition against defectors.Comment: 7 two-column pages, 3 figures; accepted for publication in Scientific

Atividade educacional utilizando realidade aumentada para o ensino de física no ensino superior : Educational activity using Augmented Reality for Teaching Physics in Higher Education
O uso de recursos de Realidade Aumentada em dispositivos móveis para a Educação tem sido explorado nos últimos anos de forma mais significativa. Desta forma, o objetivo deste artigo foi avaliar a qualidade de uma abordagem educacional neste contexto em termos de Usabilidade, Engajamento, Motivação e Aprendizagem. Um estudo voltado para o processo de ensino e aprendizagem de Física foi conduzido com 27 alunos de uma universidade federal, sendo aplicado o questionário MAREEA para avaliar a abordagem. Os resultados obtidos foram satisfatórios e instigadores, em que as quatro dimensões foram avaliadas positivamente, havendo também um importante feedback dos participantes para as melhorias nos recursos educacionais em realidade aumentada.The use of Augmented Reality features in mobile devices for Education has been explored in recent years in a more meaningful way. In this way, the objective of this article was to evaluate the quality of an educational approach in this context in terms of Usability, Engagement, Motivation, and Learning. A study focused on the teaching and learning process of Physics was conducted with 27 students from a federal university, using the MAREEA questionnaire to evaluate the approach. The results were satisfactory and instigators, in which the four dimensions were evaluated positively, and there was also significant feedback from the participants for improvements in educational resources in augmented reality.Facultad de Informátic
Benevolent characteristics promote cooperative behaviour among humans
Cooperation is fundamental to the evolution of human society. We regularly
observe cooperative behaviour in everyday life and in controlled experiments
with anonymous people, even though standard economic models predict that they
should deviate from the collective interest and act so as to maximise their own
individual payoff. However, there is typically heterogeneity across subjects:
some may cooperate, while others may not. Since individual factors promoting
cooperation could be used by institutions to indirectly prime cooperation, this
heterogeneity raises the important question of who these cooperators are. We
have conducted a series of experiments to study whether benevolence, defined as
a unilateral act of paying a cost to increase the welfare of someone else
beyond one's own, is related to cooperation in a subsequent one-shot anonymous
Prisoner's dilemma. Contrary to the predictions of the widely used inequity
aversion models, we find that benevolence does exist and a large majority of
people behave this way. We also find benevolence to be correlated with
cooperative behaviour. Finally, we show a causal link between benevolence and
cooperation: priming people to think positively about benevolent behaviour
makes them significantly more cooperative than priming them to think
malevolently. Thus benevolent people exist and cooperate more
