The Effects of Retail Regulations on Prices Evidence form the Loi Galland
In 1997, a new legislation banning below-invoice retail prices came into force in France. Individually negotiated discounts could no longer be passed on to consumers, which is equivalent to allowing industry-wide price oors. The anti-competitive effects of such practices are well-known. The elimination of intra-brand competition is expected to lead to a sharp increase in the retail prices. Using CPI raw data, we nd evidence supporting this claim. The modification or revocation of the existing legislation (as it has been done in Ireland in December 2005) would then be expected to reduce retail prices.retail prices, pricing regulations, resale price maintenance

Contrôle des installations d’assainissement non collectif : l’apport déterminant des outils de diagnostic non destructifs
Depuis juillet 2012, un nouveau cadre juridique s’applique aux installations d’assainissement non collectif, visant à améliorer leur contrôle et leur rénovation progressive. Cette note nous présente une méthodologie de contrôle simplifié des installations élaborée grâce l’apport déterminant des outils de diagnostic non destructifs
The Environmental Effect of Green Taxation: the Case of the French "Bonus/Malus"
At the beginning of 2008 was introduced in France a feebate on the purchase of new cars called the Bonus/Malus. Since January 2008, less polluting cars benefit from a price reduction of up to 1,000 euros, while the most polluting ones are subject to a taxation of 2,600 euros. We estimate the impact of this policy on carbon dioxide emissions in the short and long run. These emissions depend on the market shares and the average emissions per kilometer of each car, but also on their manufacturing, car fleet size and the average number of kilometers travelled by their owners. We first develop a simple tractable model that relates car choice and mileage. We then estimate this model, using both the exhaustive dataset of car registrations and a recent transportation survey which provides information on individual journeys. We show that if the shift towards classes benefiting from rebates is spectacular, the environmental impact of the policy is negative. The reform has notably increased sales, leading to an important increase in manufacturing and travelling emissions. We thus stress that such policies may be efficient tool for reducing CO2 emissions since consumers do react to such financial incentives, but should be designed with care to achieve their primary goal.environmental taxation, automobiles, carbon dioxide emissions, policy evaluation
3D-printed system optimizing dissolution of hyperpolarized gaseous species for micro-sized NMR
International audienceDissolution of hyperpolarized species in liquids of interest for NMR is often hampered by the presence of bubbles that degrade the field homogeneity. Here a device constituted by a bubble pump and a miniaturized NMR cell fitting both inside the narrow bore of an NMR magnet is built by 3D printing. 129Xe NMR experiments performed with hyperpolarized xenon reveal high and homogeneous dissolution of the gas in water
The Impact of Dielectric Constant Model and Surface Reference on Differences Between SMOS and Aquarius Sea Surface Salinity
Two ongoing space missions share the scientific objective of mapping the global Sea Surface Salinity (SSS), yet their observations show significant discrepancies. ESA's Soil Moisture and Ocean Salinity (SMOS) and NASA's Aquarius use L-band (1.4 GHz) radiometers to measure emission from the sea surface and retrieve SSS. Significant differences in SSS retrieved by both sensors are observed, with SMOS SSS being generally lower than Aquarius SSS, except for very cold waters where SMOS SSS is the highest overall. Figure 1 is an example of the difference between the SSS retrieved by SMOS and Aquarius averaged over one month and 1 degree in longitude and latitude. Differences are mostly between -1 psu and +1 psu (psu, practical salinity unit), with a significant regional and latitudinal dependence. We investigate the impact of the vicarious calibration and retrieval algorithm used by both mission on these differences
The sonic spectrums of skateboarding: from polarity to plurality
This is the final version. Available on open access from Routledge via the DOI in this recordThe sounds produced by skateboards, or skatesounds, are a common basis of complaint among the urban public and yet a source of inspiration and joy for skateboarding participants. These opposing responses to skatesound have escaped scholarly attention due to skateboarding’s visuocentric culture, yet this disagreement is significant in planning for city-built skateparks, registering public complaints of skateboarders in city spaces, and adding hostile architecture like skate stoppers, which often pivot on this polarity of reactions to skatesounds. We present a spectrum of theoretical responses of skatesound to dispel these reactions, including subjectivism, semiotics, soundscapes, and texturology. We argue that for some people skatesounds may be merely subjective with either a positive or negative valence. For others, skatesound is associated with pro-social or anti-social behaviors. For some, skatesound is both associative and provides wayfinding information about a city. Lastly, we introduce a novel theory of texturology: that skateboarders possess a unique sensory knowledge of the surface materials and textures of the city through skatesound, a knowledge specific to skateboarding
Environmental Asbestotic Pleural Plaques in Northeast Corsica: Correlations with Airborne and Pleural Mineralogic Analysis
We report a prevalence study of environmental pleural plaques in subjects over 50 years old from the northeastern Corsican village of Murato, built on asbestos surface deposits. The percentage of plaques was 41%, versus 7.5% in the control village of Vezzani. Although surface deposits contain both chrysotile and tremolite, airborne pollution and asbestos lung burden of exposed inhabitants consist essentially of tremolite as assessed by transmission electron microscopy (TEM). However, TEM analysis of the parietal pleura of three animals bred in exposed areas showed a predominance of short fibers of chrysotile. The respective roles of tremolite and chrysotile in inducing pleural plaques in Corsica should thus be considered.—Environ Health Perspect 102(Suppl 5):251–252 (1994
