Teamwork is crucial to organizational success and commitment to teams is an important predictor of team-related behaviors. However, theorists and researchers have typically assumed that commitment levels are generally stable within-persons, increasing or decreasing as a result of substantial organizational changes. This position is at odds with the evidence of systematic and regular intraindividual fluctuations in personal attributes and workplace behaviors. We draw upon affective events theory to present a model explaining how certain events and dispositions produce vacillations in affective reactions which, in turn, are likely to create within-person variation in affective commitment to teams (WPVCteams). We further propose that WPVCteams enhances prediction and explanation of intraindividual fluctuations in work behavior and, interindividually, moderates the relationship between level of commitment and behavior. 相似文献

Products with a superior environmental performance, such as a high level of energy efficiency, are typically subject to information asymmetries. Therefore these product attributes are often undervalued in purchase decisions. Signaling, e.g. energy labeling, can overcome these asymmetries, with positive implications for effective consumer decisions, competitive advantage for suppliers of energy‐efficient goods, and for societal goals such as mitigating climate change. However, there is a scarcity of research investigating how energy labels actually influence consumer choice. The recent revision of the European Union energy label provided a unique opportunity to investigate the effectiveness of energy labeling in a quasi field‐experimental setting. We show that the proposed extension of the seven‐point A–G rating scale by adding new classes A+, A++, etc. will result in a lower perceived importance of energy efficiency in consumer decision‐making. Based on a stated preference survey investigating 2244 choices by German consumers, we conclude that the revision actually undermines the label's ability to overcome information asymmetries, hence potentially contributing to market failure.

A note on decomposing the Malmquist productivity index by means of subvector homotheticity 总被引:1,自引:0,他引:1

Summary. This paper introduces a decomposition of the Malmquist productivity index into component indexes. The motivation is to derive
an analogue of the decomposition of the T?rnqvist index into productivity and quality change provided by Fixler and Zieschang
(1992) to the Malmquist index. Since we employ no second order approximations, this decomposition requires additional structure,
namely a generalized version of Shephard's (1970) inverse homotheticity, which we dub subvector homotheticity. We show that
subvector homotheticity is necessary and sufficient for our decomposition.

Translation homotheticity 总被引:2,自引:0,他引:2
Summary. The concept of translation homotheticity is introduced and defined. It is demonstrated that translation homotheticity is
necessary and sufficient for: disposable surplus to be independent of the reference utility, Luenberger's compensating and
equivalent benefits to be independent of the reference utility and always equal to one another, the risk premium to be independent
of reference-level utility, absolute indexes of income inequality to be reference free, and social-welfare functionals to
satisfy invariance with respect to the choice of a common origin. Translation homotheticity is also sufficient for Hicks'
many-market consumer surplus measure to be a second-order approximation to disposable surplus, compensating benefit, and equivalent
benefit. If preferences are translation homothetic and appropriately quadratic, Hicks, many-market consumer surplus measure
is exact for these welfare measures.

A qualitative response model is applied to study the relationship between environmental regulations and plant exit. The data set is Norwegian panel data for establishments in three manufacturing sectors that have high shares of units which have been under strict environmental regulations. In two of the sectors, the estimated exit probability of regulated establishments is, ceteris paribus, only one third of the exit probability of non-regulated establishments. We also find that the probability to change regulation status from being non-regulated to become regulated depends significantly on economic factors. In particular, establishments with weak profitability had the highest probability to come under environmental regulation. 相似文献
