This paper investigates the evolution of prices and returns in the art market since the middle of the previous century. We first compile a comprehensive list of more than 10,000 artists and then build a dataset that contains information on more than 1.1 million auction sales of paintings, prints, and works on paper. We perform an extensive hedonic regression analysis that includes unique price-...

Amphetamine microinjection into the nucleus accumbens shell enhanced the ability of a Pavlovian reward cue to trigger increased instrumental performance for sucrose reward in a pure conditioned incentive paradigm. Rats were first trained to press one of two levers to obtain sucrose pellets. They were separately conditioned to associate a Pavlovian cue (30 sec light) with free sucrose pellets. O...

Over the last decade, a wealth of research has examined the potential benefits of product recommendation agents (PRAs) for improving outcomes for e-commerce consumers and vendors. To date, however, this research has largely overlooked the fundamentally social nature of shopping. In particular, people often shop collaboratively (together) and for hedonic reasons (for enjoyment), but researchers ...

Background This paper presents a re-analysis of the gene set data from Fredrickson et al. 2013 [8] and Fredrickson et al. 2015 [7] which purportedly showed opposing effects of hedonic and eudaimonic happiness on the expression levels of a set of genes that have been correlated with social adversity. Fredrickson et al. 2015 [7] used a linear model of fixed effects with correlated error (using GL...

Prenatal ethanol exposure can result in social deficits in humans and animals, including altered social interaction and poor communication. Rats exposed to ethanol prenatally show reduced play fighting, and a combination of prenatal ethanol exposure and neonatal whisker clipping further reduces play fighting compared with ethanol exposure alone. In this study, we explored whether expression of ...

OBJECTIVE This study describes a quantitative and qualitative methodology to assess hedonic responses to sweet stimulus in healthy newborns. METHODS A descriptive, cross-sectional, observational study, with healthy newborns (up to 24h of life), between 37 and 42 gestational weeks, vaginally born and breastfed previously to all tests. The evaluation of the newborns reactions was performed by h...

Consider a nonseparable model Y = R(X,U) where Y and X are observed, while U is unobserved and conditionally independent of X. This paper provides the first nonparametric test of whether R takes the form of a transformation model, meaning that Y is monotonic in the sum of a function of X plus a function of U . Transformation models of this form are commonly assumed in economics, including, e.g....

recognizing the importance of the advertising in brand reinforcement and brand credibility, the authors conduct the present research for understanding the customers’ emotional responses toward the brand reinforcement and credibility and its effect on the perceived values and behavioral intentions. hypotheses were tested on data collected from 467 customers of mellat bank in semnan province in i...

With the experiential turn in Human–Computer Interaction (HCI), academics and practitioners broaden their focus from mere task-fulfillment (i.e., the pragmatic) to a holistic view, encompassing universal human needs such as relatedness or popularity (i.e., the hedonic). Accordingly, many theoretical models of User Experience (UX) acknowledge the hedonic as an important aspect of a product’s app...

Sensory preferences for fat in foods are influenced both by subject characteristics and by the nature of the food stimulus. Hedonic responses to sugar/fat mixtures depend on strong interactions between perceptions of the two ingredients, including tactile as well as gustatory effects. Fat-containing liquid and solid foods, and dessert-type sugar/fat mixtures produce different hedonic response p...
