Spatial Autocorrelation in Econometric Land Use Models: An Overview
2021
International audience; This chapter provides an overview of the literature on econometric land use models including spatial autocorrelation. These models are useful to analyze the determinants of land use changes and to study their implications for the environment (carbon stocks, water quality, biodiversity, ecosystem services). Recent methodological advances in spatial econometrics have improved the quality of econometric models allowing them to identify more precisely the determinants of land use changes and make more accurate land use predictions. We review the current state of the literature on studies which account explicitly for spatial autocorrelation in econometric land use models …
Product information, hedonic evaluation, and purchase decision: an experimental study of orange juice
2007
AbstractTwo randomly sampled groups of subjects were endowed with real budgets and placed in 5 different budget/price situations. In each situation they had to evaluate 6 orange juices and complete a demand table. At the end of the experiment, one demand table was randomly selected and participants had to buy the corresponding products. In one group, participants choose after looking at the packaging in the other they could also taste the products. Results show that participants who chose without tasting, made quicker decisions, selected a larger number of variants and were more influenced by prices than those who could taste the products. Although choices appeared very heterogeneous, most …
Respondent Uncertainty and Ordering Effect on Willingness to Pay for Salt Marsh Conservation in the Brest Roadstead (France)
2017
International audience; This paper explores the potential link between the sensitivity of willingness to pay (WTP) to the order of presenting bid amounts in contingent valuation questions (ordering effect) and respondent uncertainty. The resource being valued is a public project to protect salt marshes against the spread of an invasive aquatic plant in the Brest roadstead (France). Valuation uncertainty is captured through a variant of payment card format where respondents are given the opportunity to report their WTP as either a single value (Option A) or an interval of values (Option B). The ordering effect is tested using both parametric models that ignore and control for the potential s…
When is Green Really Green? A Latvian Case Study on Updating of Food Supply Green Public Procurement
2020
Abstract Green public procurement (GPP) is an important tool and is used to reduce adverse environmental impacts caused by food production. To have a more detailed look at the application of GPP in Latvia, the authors screened 97 public tenders for supply of food products, documenting the choice of the green criteria. Only 15 % of the screened tender documents corresponded to the national GPP requirements. Only 4 % of the tender documents gave higher priority exclusively for organic products compared to products within national quality schemes or integrated pest management agriculture. The authors compared these findings with the opinions of environmental experts, GPP guidelines by the Euro…
Urban consumers’ attitudes and willingness to pay for functional foods in Iran: A case of dietary sugar
2017
Growing concerns for the incidence of incurable diseases and high costs of health care have attracted consumers to functional foods in the world. These foods are characterized with health improvement, lower risk of disease incidence and less health hazards. The present work examined consumers’ attitude and willingness to pay for dietary sugar in Rasht city, Iran. The studied sample included 125 citizens of Rasht in spring and summer of 2016 whose size was determined by Mitchell and Carson approach. Results of contingent valuation method on the basis of one-and-one-half-bound choice model revealed that the descriptive variable of bid had negative, statistically significant impact on the acce…
The sicilian cooperative system of wine production: the strategic choices and performance analyses of a case study
2020
Purpose The purpose of this paper is to verify whether, besides the traditional organisational models mainly implemented by wine-making cooperatives, more modern and hybrid organisational forms can be profitably applied within an increasingly competitive wine market. Design/methodology/approach The study outlined in this paper deployed a mixed method. Specifically, an archived analysis, a survey and a descriptive case study (including visits, interviews and documentary analysis) were the methodological techniques used in this study, which were “in series but integrated” between themselves. In this paper, the landscape of Sicilian wine cooperatives is described by collating and processing d…
The premium price for Italian red wines in new world wine consuming countries: the case of the Russian market
2017
Italian wine is increasingly appreciated in new world consumer countries and, in particular, in Russia where consumers associate its consumption with an Italian lifestyle. In this paper, market value for wine search attributes is measured through the estimation of a hedonic price model using online data from a Wine Searcher website and the information contained in the labels of wines marketed in Russia. Results show a premium price for wines from Piedmont and Tuscany, and in particular for non-native varieties and for Indicazione Geografica Tipica and Protected Geographical Indication wines. Additionally, vintage and higher alcohol content have a significant positive impact on the prices th…
Multifunctionality: refocusing a spreading, loose and fashionable concept for looking at sustainability?
2008
International audience; The notion of agriculture's Multifunctionality (MF) emerged in the 1980s. It then followed two trajectories since the 1990s: a conflicting period linked to its use in the international trade negotiations on the one hand, a spreading in terms of meaning, use and geographically on the other hand. Specific meanings appeared in connection with policy making, at national or international levels, or through the involvement of new disciplines. Yet, very few authors discuss the implication of the chosen meaning on their findings. To explore and take advantage of using this word and to deliver it from its controversial use in international trade negotiations, it is absolutely…
Environmental spillovers and their impacts on housing prices: A spatial hedonic analysis
2015
This paper investigates the spatial dimension of environmental factors on housing prices. We develop spatial hedonic models to estimate the implicit prices of various environmental attributes. The spatial dimension can be interpreted in terms of local or global spillovers. We conduct an empirical study in the Loire estuary (France). We focus on natural areas and more artificialized ones (ocean frontage, wetlands, rivers, and noisy roads). We show that, depending on the spatial model used, the implicit price is more than just the estimated coefficient value and combines both a feedback effect and a propagation effect.
Assessing the effect of information on the reservation price for Champagne: what are consumers actually paying for?
2018
AbstractTwo series of Vickrey auctions have been performed to assess the effect of packaging information (bottle and label) on the reservation prices of ordinary consumers for five brut non-vintage Champagnes. As in other studies on wine tasting, packaging information is found to explain much more of the variation in willingness to pay than sensory information. Participants are unable, or unwilling, to put different values on the Champagnes after blind tasting, but significant differences in reservation prices appear when labels are disclosed. Detailed analysis of choices reveals a large heterogeneity in individual behaviors and valuations of the Champagnes included in this study. (JEL Clas…
