La valeur économique des paysages des villes périurbanisées
2007
La recherche présentée ici propose une méthode de description et d’évaluation des caractéristiques d’un paysage qui combine la géographie quantitative et l’économétrie des modèles hédoniques. Un modèle géographique produit des indices caractérisant les paysages à partir d’une reconstitution de la vue depuis le sol, en tenant compte des effets du relief et des masques que les objets hauts opposent à la vue. Il décrit la quantité de paysage vu par un observateur au niveau du sol en la répartissant entre 13 types d’occupations du sol. Les variables produites par le modèle géographique sont utilisées dans des régressions hédoniques qui permettent d’évaluer l’impact des attributs paysagers ain…
A study on the assessment of the production costs curves in micro-grids
2013
In micro-grids, due to their small scale, there is commonly only one power supplier. A competitive wholesale market hardly exists, so the question about how to consider market issues for small producers within micro-grids arises. On the other hand, the specific features of micro-grids where load and generated power hardly find a balance, require that customers take part to regulation issues, also using demand-response (DR) programs. In this paper, price responsive (PR) policies and their programs are discussed to answer this question. A case study of a micro-grid with one micro-turbine and two photovoltaic (PV) generators is analyzed to assess the overall production cost in order to build a…
The Influence of Agricultural Support on Sale Prices of French Farmland: A Comparison of Different Subsidies, Accounting for the Role of Environmenta…
2013
In this paper, using data from individual transactions for the period 1994-2010 in the French NUTS2 region Brittany, we investigated how environmental regulations and transaction land regulations influence the price of sold plots. Regressions on three sub-samples of buyers were performed in order to assess whether different buyers have different attitude or plans regarding the farmland purchased: a sub-sample including only farmer buyers, a sub-sample including non-farmer individual buyers, and a sub-sample including non-farmer nonindividual buyers. Estimations were performed ignoring and accounting for spatial interactions (model SARAR). Results indicate that the price of land decreases wh…
Observing The Decision-Making Process
2016
International audience; In this chapter we ask how knowledge can be acquired about the decision-making processes associated with residential choice. As shown by the results of the many areas of research set out in chapter 2, a great number of factors may influence the decision to move home. Because we are more especially interested in the actual decision-making process, we must consider the mental factors that may condition it.
Bodźce pozacenowe w kontraktach rolnych. Powiązania umowne między grupami producentów rolnych a ich pierwszymi odbiorcami w Polsce
2018
Celem artykułu jest identyfikacja stosowanych bodźców pozacenowych w umowach rolnych, które mogłyby potencjalnie skłaniać agenta do działania zgodnego z interesem kontraktora. Zastosowanie tego typu zachęt może potencjalnie minimalizować problem pokusy nadużycia ze strony agenta jeszcze w trakcie jej obowiązywania, tj. w trakcie produkcji rolnej. Dla realizacji założonego celu wykorzystano badanie własne z użyciem ankiety. Badanie empiryczne przeprowadzono wśród grup producentów rolnych działających na rynku drobiu, a przedmiotem badań były kontrakty rolne podpisane w 2014 roku. Na podstawie przeprowadzonych badań zidentyfikowano bodźce pozacenowe, które mają pomóc monitorować i łagodzić pr…
Economic Aspects of Hybrid Cloud Infrastructure: User Organization Perspective
2012
Adoption of cloud infrastructure promises enterprises numerous bene- ts, such as faster time-to-market and improved scalability enabled by on-demand provisioning of pooled and shared computing resources. In particular, hybrid clouds, by combining the private in-house capacity with the on-demand capacity of public clouds, promise to achieve both increased utilization rate of the in-house infrastructure and limited use of the more expensive public cloud, thereby lowering the total costs for a cloud user organization. In this paper, an analytical model of hybrid cloud costs is introduced, wherein the costs of computing and data communication are taken into account. Using this model, a cost-e c…
Does corn market uncertainty impact the US ethanol prices?
2018
The growing interest in biofuel as a green energy source has intensified the linkages between corn and ethanol markets, especially in the United States that represents the largest producing and exporting country for ethanol in the world. In this study, we examine the effect of corn market uncertainty on the price changes of US ethanol applying a set of GARCH-jump models. We find that the US ethanol price changes react positively to the corn market volatility shocks after controlling for the effect of oil price uncertainty. In addition, we document that the impact of corn price volatility on the US ethanol prices appears to be asymmetric. Specifically, only the positive corn market volatilit…
