Hedonic analysis

This limited appeal of persistence as a chemical characteristic is evident in the results of the hedonic analysis undertaken by Soderqvist (Chapter 3, thisvolume). In that study there was no clear link foundbetween the trait of persistence and the farmers willingness to pay for the chemical. This was one of the more surprising results from that study.

In order to produce the information needed for a hedonic analysis of the demand for pesticide characteristics (Soderqvist, Chapters, this volume), five properties of the herbicides, for which a continuous quantification was possible, have been selected price, persistence, action spectrum, reliability and toxicity. These properties cover approximately 10 out of 13 of the factors indicated in Table 2.5. Quantitative information for the five properties has been provided for the alternatives to atrazine, in order to provide input data for economic modelling (Soderqvist, Chapter 3, this volume). 

Finally, the hedonic analysis in this chapter may provide a basis for a more advanced analysis of farmers selection of treatment alternatives and the prediction of future herbicide use. This presupposes, however, a successful combination of the hedonic model and the treatment selection model sketched earlier. As was noted on p. 53, thewayto accomplish such a combination has stiU to be studied carefully. Regional hedonic price functions may be necessary for estimations, and individual date on farmers treatment choices are desirable.

In sensory science, the common practice is to conduct hedonic and descriptive analysis separately. Hedonic analysis is conducted with consumers who evaluate the products in terms of liking (Thomson, 1988), whereas descriptive analysis is traditionally conducted with expert, or trained, panellists who generate sensory profiles of the products (Stone et al, 1974 Stone and Sidel, 2(X)4 Meilgaard et al., 2007).

Method The authors use information on all non-hospital sales of pharmaceutical products in 1992 in a sample of countries consisting of the USA, Canada, Germany, France, Italy, Japan and the UK. The database was provided by Intercontinental Medical Systems (IMS). The empirical analysis is based on the calculation of the Paasche and Laspeyres price indexes and the ratio between them. The descriptive analysis is completed with the econometric analysis (quasi-hedonic model) of the determining factors of the variation in the relative prices of each active ingredient in each country taking the USA as the point of comparison.

However, a single GC-O run only is usually insufficient to distinguish between the potent odorants that most likely contribute strongly to an aroma and those odorants that are only components of the background aroma. Therefore, to improve the results, two methods, combined hedonic aroma response measurements (CHARM) analysis [4] and aroma extract dilution analysis (AEDA) [5, 6] have been developed. As discussed in Sect. 16.4 in both methods serial dilutions of food extract are analysed by GC-O.

These methods were developed to quantify and visualize the intensity of aroma as a chromatogram. A specific system named combined hedonic and response measurement (CHARM) was initially developed. Later on, aroma extract dilution analysis (AEDA) (Figure 3), a new method using a conventional GC-O system, was proposed. They share the same strategy aroma extract is diluted to a certain extent and then GC—O methodology is applied. In an AEDA procedure, if such a maximum extent of a dilution that allows the detection of a certain component is times diluted from the original sample, this component is referred to have a flavor dilution (FD) factor of . CHARM value corresponds to FD factor in a CHARM procedure. These values represent the contribution of the volatile the larger these values are, the more important they are considered as key components. 

Over the past half century, the held of economics has developed a rich and extensive literature that advances the theory and methodology of estimating values associated with the myriad unmarketed yet economically valuable benefits provided by nature. While the literature is vast, the number of approaches available to estimate the economic value of ecosystem services remains limited to only a handful, each with its own strengths and weaknesses (for comprehensive reviews, see Mitchell and Carson, 1989 Freeman, 1993 Smith, 2000 Mathis et al., 2003). These include replacement costs and avoided costs analysis, factor income analysis, hedonic pricing, contingent valuation, and travel costs analysis. A discussion of these approaches follows later in this section. Although there is often considerable debate about the methods used and the accuracy of the values derived, there is little doubt that the unpriced economic value of ecosystem services is enormous.9... 

It was also checked whether any differences would arise when separate hedonic price functions are estimated for each of the eight years in the period of 1987-1994 (and for each of the specifications A, B and C). It is possible to develop this type of quite informal analysis into a formal analysis of pooling. A complication is that, in any event, the number of observations is small. We stick to the informal analysis here in order to obtain some rough indications of potential coefficient instability over time. Figures 3.2a and b show the results for these annual hedonic price... 

An obvious shortcoming with the analysis so far is that the supply side has not been considered explicitly. It is possible that it has been taken into account implicitly, since the four studied characteristics may be determinants not only for farmers treatment choices, but also for producers supply decisions. This complex issue is discussed in the last section. However, we now turn to study how the estimated hedonic price function is influenced by the introduction of some variables that are related explicitly to the supply of herbicides. 

Improvements to the Model. Since other odor notes undoubtedly influence the scores of some selected odor notes, additional variables were added to the simple regression model above on a multiple stepwise regression analysis was conducted. For each odor note, the other candidate variables were all other 29 descriptor scores, and the hedonic tone of the hedonically lowest (least pleasant or most unpleasant) and highest components.

These three implications of conventional economic theory have had far-reaching effects on public policy, despite their incompatibility with the views held by nearly all noneconomists. In the analysis which takes up the rest of this book I will refer to them respectively as the efficiency, equity, and hedonic properties of the competitive market model. I will explore the underlying model on its own terms to determine more precisely the conditions that are required for each of these properties to hold. This will involve a detailed review of the theoretical structure of the model, as well as the econometric procedures required to compensate for the lack of fully satisfactory data. 

Finally, over the course of this chapter we have seen increasingly sophisticated attempts to overcome the problems which bedevil hedonic wage analysis. From simple, unadorned wage regressions we moved to partitioned samples, inclusion of workers compensation benefits, canonical correlation to test for implicit bias, and an estimation of the likelihood of job-switching to circumvent the difficulties connected with unemployment. It is true that these more refined methods yield results... 

Even if job evaluation were a widespread source of wage compensation, this fact would not rescue economic theories of market performance, nor the doubtful foundations of hedonic wage analysis. But despite the best efforts of professional evaluators, compensation is as scarce within firms as it is between them. 

This last term is widely used in economics to refer to the process of decomposing the price of complex goods into the prices of their constituent elements. The intellectual justification for this practice comes from utilitarian preference analysis, in which consumers are said to adhere to a unitary hedonic calculus for all positive and negative outcomes that may arise.
