Transparency, Inequity Aversion, and the Dynamics of Peer Pressure in Teams: Theory and Evidence

We provide an explanation for peer pressure in teams based on inequity aversion. Analyzing a two-period model with two agents, we find that the effect of inequity aversion strongly depends on the information structure. When contributions are unobservable, agents act as if they were purely selfish. However, when contributions are made transparent at an interim stage, agents exert higher efforts in the first period and adjust their efforts according to the interim information in the second period. This form of peer pressure reduces free-riding and thus, more efficient outcomes are attained. The results are confirmed in a real effort experiment.real effort, team, transparency, peer pressure, free-riding, incentives, inequity aversion, experiment

Who benefits from benefits? Empirical research on tangible incentives

Although a broad field of literature on incentive theory exists, employer-provided tangible goods (hereafter called benefits) have so far been neglected by economic research. A remarkable exception is an empirical study by Oyer (2008). In our study, we test some of his findings by drawing on a German data set. We use two waves of the GSOEP data (2006, 2008) to analyze the occurrence of benefits and their effects on employees' satisfaction. Our results provide evidence for economic as well as psychological explanations. Looking at differences in firms' and employees' characteristics we find that cost efficiency concerns, the purpose to signal good working conditions and the aim to ease employees' effort costs are evident reasons to provide benefits. Furthermore, analyzing the impact of tangible and monetary incentives on satisfaction and employees' feeling of being acknowledged by employers, we find different motivational effects. Our results support the psychological explanation that benefits are evaluated separately from other monetary wage components and are more likely to express employers' concern for their employees and recognition of their performance

Impact of working hours on work-life balance

To examine the influence of working hours on employees' satisfaction, this article uses a large, representative set of panel data from German households (GSOEP). The results show that high working hours and overtime in general do not lead to decreased satisfaction. Rather, increasing working hours and overtime have positive effects on life and job satisfaction, whereas the desire to reduce working hours has a negative impact on satisfaction. In 2009, nearly 60% of employees wanted to reduce their working hours. The overall number of hours by which employees want to reduce their working time is driven mainly by overtime compensation

Whom to choose as a team mate? A lab experiment about in-group favouritism

The practical relevance of favouritism among students of the same study path is evident in lifelong memberships in fraternities or sororities or in high donations to faculties. In our study, we focus on the in-group favouritism of students by examining the trade-off of acting based on in-group favouritism or a performance signal when decisions are made about whom to choose as a team mate. The novel feature of your study is that the choice of a team mate is either benevolence or relevant to the own output. In the first scenario, only the payoff of the chosen subject changed, whereas in the second scenario, the decision affected the decider's own payoff as well as that of the chosen subject. The subjects ex ante knew the group type (path of study) of the pool of possible team mates and received a signal giving weak information about their ability regarding the task. Intuitively, one would expect more favouritism if the own payoff was not affected by the performance of the chosen team mate. However, we found the opposite. The subjects exerted more favouritism in the revenue sharing scenario. Possibly they expected reciprocal behaviour and less free riding if they selected a team mate belonging to their own group. Interestingly, groups formed based on favouritism did not perform significantly different from groups formed based on the performance signal

Energy efficiency in production processes – the influence of consumption visualization and staff training

Part of: Seliger, Günther (Ed.): Innovative solutions : proceedings / 11th Global Conference on Sustainable Manufacturing, Berlin, Germany, 23rd - 25th September, 2013. - Berlin: Universitätsverlag der TU Berlin, 2013. - ISBN 978-3-7983-2609-5 (online). - http://nbn-resolving.de/urn:nbn:de:kobv:83-opus4-40276. - pp. 181–186.This paper examines the influence of the visualization of consumed compressed air and staff training on the consumption behavior of employees in a real production process. To measure potential changes in consumption behavior a real-effort experiment at the Training Factory for Energy Productivity, a real production setting at iwb of TUM, had been designed. Therefore, four groups were defined, each group in a different experimental setting. This experiment is the first one ever conducted in a real-life setting and thus adds valuable results to academia and practitioners. Compared to the group without any information about the amount of consumed compressed air the participants provided with a display showing this information saved on average 7-8%. The group provided with a movie about general measures to save compressed air in production consumed around 24% less compressed air than all other groups of participants. Generally, no significant differences between male and female participants had been found

The ovarian cancer oncobiome.

Humans and other mammals are colonized by microbial agents across the kingdom which can represent a unique microbiome pattern. Dysbiosis of the microbiome has been associated with pathology including cancer. We have identified a microbiome signature unique to ovarian cancers, one of the most lethal malignancies of the female reproductive system, primarily because of its asymptomatic nature during the early stages in development. We screened ovarian cancer samples along with matched, and non-matched control samples using our pan-pathogen array (PathoChip), combined with capture-next generation sequencing. The results show a distinct group of viral, bacterial, fungal and parasitic signatures of high significance in ovarian cases. Further analysis shows specific viral integration sites within the host genome of tumor samples, which may contribute to the carcinogenic process. The ovarian cancer microbiome signature provides insights for the development of targeted therapeutics against ovarian cancers

Parametric Optimization Of Magneto-Rheological Fluid Damper Using Particle Swarm Optimization

This paper presents a parametric modeling of a magneto-rheological (MR) damper using a Particle Swarm Optimization (PSO) method. The objective of this paper is to optimize the parameter values of the MR fluid damper behavior using the Bouc-Wen model. The parametric identification was imposed beforehand in replicating the behavior of the MR fluid damper. The algebraic function from a number of hysteresis models was steered by comparing selected models: Bingham, Bouc-Wen and BoucWen by Kwok. A simulation method was operated in investigating these models by employing MATLAB reliant from the model intricacy. The experimental data was presented in terms of the time histories of the displacement, the velocity and the force parameters, measured for both constant and variable current settings and at a selected frequency applied to the damper. The model parameters were determined using a set of experimental measurements corresponding to different current constant values. It has been shown that the MR damper model’s response via the proposed approach is in good agreement with the MR damper test rig counterpar

Martin Van Buren and the internal improvements question

The purpose of this study is to reflect the impact of Martin Van Buren exerted upon the much debated question of Federal responsibility for financing road and canal construction. Van Buren\u27s early life of hardship and his struggle to lift himself, virtually by hid bootstraps , from the ranks of mediocrity is omitted. Emphasis has been directed to service in the New York Senate, the United States Senat, Secretary of State under Andrew Jackson, Vice-President and as President. The Future President of the United States (1837-1941) served as an advocate for the various forces opposing the trend towards greater Federal control over the lives of the citizens of the new nation (1826-1831). During the latter period, the mood and temper of the people appears to hae been correctly diagnosed by Van Buren than by his chief political copetitors Henry Clay, John C. Calhoun, and Daniel Webster. As a result, Van Buren\u27s popularity and prestige continued to increase and his carefully laid plans to become President came to fruition
