An Expanded Conceptualization and a New Measure of Compulsive Buying

Drawing on the theoretical foundation of obsessive‐compulsive spectrum disorder, this article develops an expanded conceptualization and new measure of consumers’ proclivity to buy compulsively. Compulsive buying is defined as a consumer’s tendency to be preoccupied with buying that is revealed through repetitive buying and a lack of impulse control over buying. This measure includes dimensions of both obsessive‐compulsive and impulse‐control disorders. By measuring income‐dependent items or consequences of compulsive buying separately from the compulsive‐buying scale, we develop a measure that has a strong theoretical foundation, well‐documented psychometric properties, and an ability to be applied to general consumer populations

When a Promotion is Denied: The Effects of Decision Stage on Perceptions of Promotion and Price Fairness

Marketers frequently use promotions to enhance sales and increase consumers\u27 perceptions of value. However, most promotions usually come with restrictions, such as time expiration, quantity or product model restriction, etc. In the present research, the effect of the stage in the purchase process when the consumer finds out about the restriction is investigated. The findings indicate that the later in the purchase process the consumer discovers the restriction, the greater is the perception that the effort invested into the purchase is wasted, consequently resulting in lower promotion and price fairness. This effect is mediated through the feeling of entitlement to the promotional price and the inferred negative retailer\u27s motive for the promotion. Theoretical and managerial implications are also discussed

Decoherence, einselection, and the quantum origins of the classical

Decoherence is caused by the interaction with the environment. Environment monitors certain observables of the system, destroying interference between the pointer states corresponding to their eigenvalues. This leads to environment-induced superselection or einselection, a quantum process associated with selective loss of information. Einselected pointer states are stable. They can retain correlations with the rest of the Universe in spite of the environment. Einselection enforces classicality by imposing an effective ban on the vast majority of the Hilbert space, eliminating especially the flagrantly non-local "Schr\"odinger cat" states. Classical structure of phase space emerges from the quantum Hilbert space in the appropriate macroscopic limit: Combination of einselection with dynamics leads to the idealizations of a point and of a classical trajectory. In measurements, einselection replaces quantum entanglement between the apparatus and the measured system with the classical correlation.Comment: Final version of the review, with brutally compressed figures. Apart from the changes introduced in the editorial process the text is identical with that in the Rev. Mod. Phys. July issue. Also available from http://www.vjquantuminfo.or
