The effect of relative performance feedback on individual performance in team settings under group-based incentives*

This study reports the results of an experiment that analyses the behavioural effect of relative performance feedback (RPF) on individual performance when compensation is based on team performance. Specifically, it investigates whether RPF affects individual performance differently when the comparison focuses on other members of that individual’s team (within-group RPF) or on other teams (between-group RPF). We predict a negative effect of within-group RPF on individual performance. We also predict that between-group RPF moderates that negative effect, since it encourages individuals to focus on group goals rather than individual goals. Consistent with our predictions, results show that the negative effect of within-group RPF on individual performance is mitigated by between-group RPF. Our results can help accountants to better understand how the effects of relative performance feedback differ according to the predominant comparison target.     

Liquidity Pools, Risk Sharing, and Financial Contagion

This paper reevaluates the Allen–Gale (2000) analysis of interbank deposits to explain financial contagion. This paper modifies the pecking order of asset liquidation developed in Allen–Gale, which is essential in fragility analysis. Furthermore, we also provide a claim structure called liquidity pool that can both achieve risk sharing and prevent financial contagion across regions when asymmetric information about bank assets is absent. This model can partly explain why bank panics reduced substantially after the founding of the Fed and the role of IMF in regional financial crises.     

The scope of application of management accounting methods in Polish enterprises

The transformation of Poland’s economic system in the 1990s as a result of transition from a centrally planned economy to a market-based system involves significant changes in the regulatory context and in accounting practice and education.This paper presents the scope of application of management accounting concepts and methods in 60 Polish enterprises covered by a questionnaire survey carried out by the author between November 1998 and December 1999 in enterprises located in central and southern Poland. The selected companies were interviewed by means of a postal survey, with inquiry forms delivered in person in some cases.The detailed analyses carried out in this paper and the conclusions presented are also based on information obtained from documentary evidence kept by the enterprises and from direct interviews conducted in the course of work in teams engaged in analysis and assessment of cost accounting practices and in management accounting system design in a number of large and medium Polish enterprises.The empirical research carried out is aimed at verification of a number of hypotheses including the following: • modification of cost accounting systems and implementation of management accounting tools in Polish enterprises is brought about by many different factors, the most important being growth of competition and ownership changes in business entities, • Polish enterprises mostly implement the methods and techniques of operational management accounting, • short-term budgeting for cost centres is the most widely used method of management accounting.     

Living to 100 and beyond--implications of longer life spans

The challenge of longer life spans will center on the problem of allocating individual, family and social resources most effectively. To create a context for understanding the significance of measuring and forecasting mortality trends, this article addresses concerns about the implications of increasing longevity to very high ages for families, businesses and society as a whole.     

Discounting long run average growth in stochastic dynamic programs

Summary. Finding solutions to the Bellman equation often relies on restrictive boundedness assumptions. In this paper we develop a method of proof that allows to dispense with the assumption that returns are bounded from above. In applications our assumptions only imply that long run average (expected) growth is sufficiently discounted, in sharp contrast with classical assumptions either absolutely bounding growth or bounding each period (instead of long run) maximum (instead of average) growth. We discuss our work in relation to the literature and provide several examples.

A learning methodology using Matlab/Simulink for undergraduate electrical engineering courses attending to learner satisfaction outcomes

Learner-centred approaches follow the prevailing tendency in modern University reforms which are primarily concerned about “how people learn”. The methodologies can be learner-centred in the sense of placing the student as the main actor of the teaching–learning process by increasing his interactivity and participation, but also considering what is relevant for the student by measuring the learner satisfaction. In order to promote both aspects, this paper proposes a synchronous software-based active methodology that makes use of the simulations to show a virtual scenario to the students and challenge them to predict and discuss the evolution of the scenario. The proposed methodology improves the visual interface, promotes discussion both among students and with the teacher in a brainstorming stage and shows real-world examples. This software-based methodology has been implemented into an Electric Machinery course at the University of Seville (Spain), and the evaluation has been carried out considering both the affective and cognitive domains. Principal components analysis proves to be useful to highlight the dimensions with a higher influence on learner satisfaction and the affective and cognitive results confirm the successful implementation of the proposal.     

Effects of ethnic advertising on consumers of minority and majority groups: the moderating effect of humor

The effects of portrayals of ethnic endorsers in advertising are ambiguous. These portrayals strengthen the ethnic identity of ethnic minority groups, thus leading to positive responses toward the ad. They can lead to negative responses, because these portrayals can be perceived as stereotyped. Humor is a tool that can increase positive effects of identity-building and reduce negative effects of stereotyping. In this study, we investigate how humor moderates the effects of ethnic advertising on consumers from ethnic minority and majority groups. We find that humor supports the effects of traditional portrayals for both groups. Moreover, the effect of traditional portrayals combined with humor is strongest for the minority group. These findings provide evidence for the positive effects of humor in ethnic advertising and thus provide new insights to the stereotyping, ethnic advertising, and humor literature. The findings have practical implications for advertising using ethnic endorsers, humor, or targeted at ethnic minority groups.
