A Test of Basic Assumptions of Affective Events Theory (AET) in Call Centre Work1

Based on data from 2091 call centre representatives working in 85 call centres in the UK, central assumptions of affective events theory (AET) are tested. AET predicts that specific features of work (e.g. autonomy) have an impact on the arousal of emotions and moods at work that, in turn, co‐determine job satisfaction of employees. AET further proposes that job satisfaction is an evaluative judgement that mainly explains cognitive‐based behaviour, whereas emotions and moods better predict affective‐based behaviour. The results support these assumptions. A clear separation of key constructs (job satisfaction, positive and negative emotions) was possible. Moreover, correlations between several work features (e.g. supervisory support) and job satisfaction were, in part, mediated by work emotions, even when controlling for gender, age, call centre type (in‐house versus outsourced centres) and call centre size. Predictions regarding consequences of satisfaction and affect were partly corroborated as continuance commitment was more strongly related to job satisfaction than to positive emotions. In addition, affective commitment and health complaints were related to both emotions and job satisfaction to the same extent. Thus, AET is a fruitful framework for explaining why and how specific management strategies used for designing work features influence important organizational attitudes and well‐being of employees.     

Soziale Schichtung Und Delinquenz

The frequently posited relationship between social class and criminal behaviour is dubious in theory and lacking empirical evidence. Based upon the economic theory of crime by Gary S. Becker we present an extended model which integrates the effects of the individuals’ class position on their subjective evaluations of costs, utility, and the probability of being caught. Additionally, we take into account selective incentives (social opportunities) and the internalization of social norms concerning conformity (framing of the social situation) depending on social class. We test the model for two offences: shop-lifting and tax-evasion. The source of data is the German General Social Survey (ALLBUS) for the years 1990 and 2000. The empirical results support the theoretical model. There is no general relationship between the individuals’ social status and their incentives for criminal behaviour. However, the types of offences committed are affected by the social status. Subjective expected probability of failure or success is more important than fear of punishment or the expected utility. Internalized norms decrease the probability of committing a crime.     

Options Contracts with Overbooking in the Air Cargo Industry

In today's world economy, which is marked by intensified international trade, air cargo acts as a key facilitator. However, cargo airlines continue to struggle to be profitable because of very high asset costs and substantial demand uncertainty. To improve upon this situation, we propose an options contract. Our model captures the main features of cargo trade between an airline and a freight forwarder and allows us to derive an optimal reservation policy. We then go on to analyze the impact of overbooking on the profit of the cargo capacity provider. The model is subsequently applied to real‐life booking data provided by a major cargo carrier. This enables us to compare current contractual arrangements with the ones proven optimal in the model. A numerical study provides insights about the impact of overbooking on contract parameters and profitability. Managerial insights to be drawn conclude this study.     

Getting tuned in to those who are different: The role of empathy as mediator between diversity and performance

We present a theoretical model on the processes that mediate and moderate the diversity-performance relationship. Past research on this topic—for example the categorization elaboration model (van Knippenberg et al. 2004)—has often focused on information elaboration as mediator. Complementing this cognitive perspective, we propose that group diversity can also stimulate group members to engage with each other emotionally, resulting in higher levels of empathy—an emotional state which arises from the comprehension and apprehension of fellow group members’ emotional state. Empathy, in turn, is likely to enhance performance through processes within a single group member and through processes between group members. At the core of the model lies the proposition that group- as well as individual-level empathy mediate the relationship between diversity of organizational units and the performance of individual members and groups at large (multilevel mediation). Furthermore, we specify moderating conditions for the relationship between diversity and empathy. Diversity beliefs and diversity climates are introduced as second-order moderators.     

A continuous-time Markov chain approach with the analytic likelihood in studies of behavioral changes

Abstract

We develop an analytic likelihood approach for a four-state CTMC by solving the backwards Kolmogorov differential equations, reducing this bias in transition rate estimates. A simulation study is performed to assess the performance of this new method and confirms that it achieves good coverage probabilities with low bias and standard errors. Finally, we analyzed data from Project SUCCESS to estimate the study each participant’s transitions among behavioral stage, consisting of risky drinking and possible ineffective using of contraception, which comprise the primary endpoint of risk of an alcohol-exposed pregnancy.     

Labor supply responses and welfare effects from replacing current tax rules by a flat tax: Empirical evidence from Italy, Norway and Sweden

This paper employs a microeconometric framework to examine the labor supply responses and the welfare effects from replacing current tax systems in Italy, Norway and Sweden by a flat tax on total income. The flat tax rates are determined so that the tax revenues are equal to the revenues as of 1992. The flat tax rates vary from 23 per cent in Italy, 25 per cent in Norway, to 29 per cent in Sweden. In all three countries the labor supply responses decline sharply with pre-reform disposable income. The results show that the efficiency costs of the current tax systems relative to a flat tax may be rather high in Norway and much lower, but positive, in Italy and Sweden. In all three countries “rich” households – defined by their pre-tax-reform income – tend to benefit (in terms of welfare) more than “poor” households. In Italy and Sweden a majority will lose from a shift to a flat tax, while in Norway a majority is predicted to win. Received: 19 May 1998/Accepted: 02 July 1999     

Dying for charisma: Leaders' inspirational appeal increases post-mortem

In the present research, we shed light on the nature and origins of charisma by examining changes in a person's perceived charisma that follow their death. We propose that death is an event that will strengthen the connection between the leader and the group they belong to, which in turn will increase perceptions of leaders' charisma. In Study 1, results from an experimental study show that a scientist who is believed to be dead is regarded as more charismatic than the same scientist believed to be alive. Moreover, this effect was accounted for by people's perceptions that the dead scientist's fate is more strongly connected with the fate of the groups that they represent. In Study 2, a large-scale archival analysis of Heads of States who died in office in the 21st century shows that the proportion of published news items about Heads of State that include references to charisma increases significantly after their death. These results suggest that charisma is, at least in part, a social inference that increases after death. Moreover, they suggest that social influence and inspiration can be understood as products of people's capacity to embody valued social groups.
