This research aims to develop an eco-friendly shampoo formulation (Eco-Shampoo) by adding local environmental plant extracts for hair health. method is a quasi-experimental development of existing formulations (base formulations) such as aloe vera (Aloe L.) and lemongrass oil (Cymbopogon citratus) in three formulations. The resulting products were then carried out two evaluations, namely the st...

Hedonic methods are a prominent approach in the construction of house price indexes. This paper investigates in a comprehensive way whether or not there exists any kind of link between the type of price index to be computed (Dutot or Jevons) and the form of hedonic functions, hedonic methods and estimation methods, with a link being defined as a specific combination of price indexes, functions ...

Suppose two Matisse paintings with identical characteristics were put up for sale. However, one of the paintings had previously been sold in a “hot” market for a high price and the other had been sold in a “cold” market for a low price. Would the painting that previously sold in the “hot” market fetch a higher price at auction? Anchoring is one of the most powerful and well-established biases i...

Usability can be broadly defined as quality of use. However, even this broad definition neglects the contribution of perceived fun and enjoyment to user satisfaction and preferences. Therefore, we recently suggested a model taking “hedonic quality” (HQ; i.e., non-task-oriented quality aspects such as innovativeness, originality, etc.) and the subjective nature of “appealingness” into account (H...

Hedonic systems represent a multibillion-dollar industry and play an important role in how people recreate, socialize, and even conduct business. A key goal of hedonic system design is to promote positive affect—a variable known to influence cognitive beliefs, trust, disclosure, adoption, and purchase intentions. Yet, little research has identified or explained how stimuli from design feature...

This work carries out a hedonic price analysis in the Italian grappa market. We use a dataset composed of around 15.576 observations of retail chain prices (related to transactions taken place in Italy in the period 1997-2004) and product characteristics. We estimate the implicit price of the main product attributes. Results show that particularly bottle format, high alcohol content and brand a...

We hypothesize that quality signals improve over time with the quality performance of a wine producer, and that spillovers will affect other producers within the same region. For this purpose, we estimate a hedonic pricing model for premium California wine. Data source is the annual publication "California Wine Winners" accumulated over the judging years 1990-2001. Quality indicators for 19,583...

Workers and firms in a bilateral matching market choose wages and human capital investments then match assortatively. This paper studies Bayesian equilibria of finite matching games and shows that as the matching market becomes large, Bayesian equilibria can be approximated by a truncated hedonic equilibrium in the continuous matching market. We use the truncated hedonic equilibrium concept to ...
