The two primary approaches to estimate marginal willingness-to-pay (MWTP) are hedonic (Rosen, 1974) and discrete choice models (McFadden, 1974). This paper provides a tractable framework to investigate the relationship between MWTP in these models. By deriving the hedonic price gradient implicitly from the share function in the discrete choice model, I present an analytical mapping between the ...

In an attempt to account for the impact of emotion on cognition, Baddeley (2007) proposed the existence of a hedonic detection system. Malfunctioning of this system was assumed to play a crucial role in depression. Exploring this hypothesis requires a simple and rapid way of assessing the neutral point of proposed hedonic detector. We describe two experiments that aim to develop such a method o...

The quality of an organizational website can be a competitive advantage in an increasingly fierce online environment. This article identifies decisive factors of website quality and assesses their effects on user satisfaction. While past website-quality research focuses on the perspectives of web developers and designers, our study targets web users and integrates perspectives of information sy...

Over the past few years, the communication world has attended the unprecedented growth of a new media, the Internet. Websites, one of the Internet’s main tools, are being widely used in the communication process carried out by companies through the virtual environment. For that reason, further research needs to be undertaken so as to identify and understand consumers’ behaviour online. In this ...

We examined an econometric model of counts of worker absences due to illness. The underlying theoretical model is of a sluggishly adjusting hedonic labor market. We compared results from three parametric estimators, nonlinear least squares plus Poissonand negative binomial pseudo maximum likelihood, to generalized least squares using nonparametric estimates of the conditional variance. Our data...

BACKGROUND Prior meta-analyses indicated that people with schizophrenia show impairment in trait hedonic capacity but retain their state hedonic experience (valence) in laboratory-based assessments. Little is known about what is the extent of differences for state positive emotional experience (especially arousal) between people with schizophrenia and healthy controls. It is also not clear whet...

Following Lancaster’s (1966, 1979) own interpretation of his characteristics approach to consumer theory, this contribution focuses on the theoretical and empirical arguments questioning the smoothness of traditional hedonic price estimation techniques. Indeed, Lancaster argued strongly against “combinability”, i.e., that any efficient combination of characteristics is feasible and sensible, wh...

What brain reward systems mediate motivational 'wanting' and hedonic 'liking' for food rewards? And what roles do those systems play in eating disorders? This article surveys recent findings regarding brain mechanisms of hedonic 'liking', such as the existence of cubic-millimeter hedonic hotspots in nucleus accumbens and ventral pallidum for opioid amplification of sensory pleasure. It also con...
