[hal-05540926] « Ce qu’il y a de bien avec le changement climatique… »
Un documentaire récent entend brosser une image désirable de la France de 2100 à +4°C pour contrer le pessimisme ambiant. Résultat: une France rance, qui a renoncé à l'atténuation, à la justice sociale et même au bon sens. Une tribune collective rétablit les faits scientifiques sur la dévastation du système Terre et remet la question politique au premier plan.

[hal-05573667] Se passer ou pas des néonicotinoïdes ?
Cet article vise à s’interroger sur la manière dont, aujourd’hui en France, les discours et les actions se structurent dans l’espace public national autour de l’usage des néonicotinoïdes par les producteurs de betterave. S’appuyant sur les régimes d’actions « tactique-stratégique » et « de la justification », il montre comment des coups et contrecoups se succèdent dans le temps, depuis plus d’une vingtaine d’années, entre les défenseurs et les contempteurs de cet usage, et comment les uns et les autres se réfèrent, pour ce faire, à des principes supérieurs communs différents. Les événements décrits tiennent plus de la guerre larvée, avec une succession d’opérations tactiques et de moments de paix armée, et rendent compte d’une certaine incapacité politique à établir des compromis à même de permettre la construction d’une autre réalité.

[hal-05534049] Transformer les systèmes d’élevage par le jeu ?: Retour sur le processus de conception d’un jeu sérieux destiné à accompagner la transition des systèmes cunicoles
Insta’Lap est un jeu sérieux qui vise à accompagner la transition des systèmes d’élevage cunicole. Il s’agit d’un jeu de simulation permettant aux joueur·euses de concevoir un système d’élevage de lapins désirable pour eux et acceptable pour la société. Le déroulement d’une partie inclut une phase d’identification d’aspirations et de pratiques d’élevage grâce à des cartes au choix, une phase de réflexivité collective, et une phase d’évaluation multicritère de la durabilité des systèmes conçus. Au croisement des sciences sociales (sociologie et sciences de l’éducation) et de la zootechnie, le processus de conception du jeu est examiné au prisme des difficultés et frictions rencontrées dans le comité de co-conception. Insta’Lap est considéré comme un « objet-frontière » favorisant le dialogue entre les mondes sociaux cunicoles réunis au sein de ce comité. La discussion s’interroge sur la ludicité, la jouabilité d’Insta’lap et le potentiel transformatif du jeu.

[hal-05572387] Des moulins et des poissons. Appropriations de l’environnement proche en temps de bouleversements climatiques
La vague de sécheresse qui récemment a frappé la France hexagonale a renchérit et durci des conflits autour de l'aménagement des rivières. Quels usages prioriser lors que les cours d'eau s'assèchent? Comment préparer les rivières à l'intensification des sécheresses? Faut-il multiplier les petites retenues d'eau ou, au contraire, accroître la résilience du cours d'eau en favorisant les équilibres écosystémiques naturels ? Ces questions ont émergé au cours de mon enquête de thèse entre deux bassins-versants du Nord-Est de la France, une enquête portant plus généralement sur les transformations des rapport à l'environnement proche en temps de sécheresses. L'approche ethnographique montre que ces conflits environnementaux cristallisent des tensions sociales autour de l'appropriation de l'espace par différentes fractions de la (petite) bourgeoisie locale. Leur légitimité sociale à transformer l'environnement repose sur des ressources concurrentes, qui dessinent, en creux, différents modes de politisation des catastrophes environnementales, opposant schématiquement une écologie naturaliste et une écologie autonomiste.

[hal-05455600] Is compulsory inter-municipal cooperation an efficiency booster?
This paper evaluates the impact of inter-municipal cooperation on municipal efficiency in France. We exploit the “Réforme des Collectivités Territoriales” (RCT) law, approved in 2010, which forced municipalities to join an inter-municipal group (EIMC) by 2014. Focusing on Île-de-France from 2002 to 2019, we first compute municipal efficiency scores, accounting for intra- and inter-EIMC spillover effects. We then causally assess the impact of EIMC integration on municipal efficiency. We find that the RCT law increased municipal efficiency by 1.1% to 1.9%, with a stronger effect for early adopters and with increasing length of exposure.

[hal-05392358] Can public investment in transport influence densification and land use? Evidence from the tramway of Dijon (France)
Investment in public transport offers alternatives to reduce car dependency as well as many negative externalities associated with solo car usage. Yet, to be fully effective, public transport infrastructure must be able to facilitate economic activities and households’ concentration. By increasing building density around stations and corridors, transport land-use feedback cycle can be engaged. The paper aims to evaluate the existence and extent of the causal relationship between public investment and densification, leveraging the implementation of a tramway service in the metropole of Dijon (France). The analysis decomposes the impact by direction as well as by the distance to corridor and city center. The results suggest that investment in public transport systems can significantly affect population and/or employment densification patterns, but that success is largely linked to the political willingness to stimulate densification through facilitating private investment.

[hal-05477824] Vulmob, a multidimensional vulnerability indicator to assess the impact of policies limiting car use - application to the Grenoble LEZ
Social (in)justice is an argument often put forward to explain the successive setbacks to the rollout of low-emission zones (LEZs) in France. However, until now, this is not based on any rigorous assessment. We are developing a methodology for assessing the impact of a LEZ on mobility vulnerabilities based on a multidimensional vulnerability indicator (VulMob). We apply this methodology to the Grenoble region. Firstly, we show that the number of households without a solution is extremely low and that there are solutions to help these households specifically, without calling the whole policy into question. Moreover, modal shift appears to be a high-potential adaptation solution for all households, which could improve the environmental and health performance of the LEZs. It should be noted, however, that highly vulnerable households are more affected and more likely to remain without a solution other than buying a car that complies with the LEZ. This work can guide the operational implementation of the LEZs and the definition of support policies, taking into account vulnerability profiles and the specific characteristics of the area

[hal-05490782] From Sharing to Capitalizing: Evaluating the Rise of Airbnb in Housing Prices
This paper investigates the causal impact of short‐term rentals (STRs) on housing prices across French municipalities in 2018−2019. Using Airbnb data and a novel demand‐shock instrument, we isolate exogenous variation in STR supply. A 1% increase in STR density raises local housing prices by an average of 11%, with stronger effects in densely populated, supply‐constrained cities and in non‐touristic rural areas. Results also show substantial heterogeneity between professional and non‐professional hosts, the latter driving most of the capitalization effect. By combining platform and administrative data, the paper provides new evidence on how tourism‐driven housing demand shapes real‐estate markets.

[hal-05490824] Managing Pesticide Resistance: Input‐Oriented Versus Result‐Oriented Tax Systems
Pesticide resistance is a phenomenon that is becoming increasingly worrying. Heavy reliance on pesticides in the agricultural sector is at the core of this problem. In this paper, we analyse how farmers' pest control strategies can reduce pesticide resistance. We show that Integrated Pest Management is effective in limiting the growth of pesticide resistance. However, because one farmer's choices affect those of their neighbours, externalities remain and public policies are needed. We analyse two tax systems where one is polluting input‐oriented and the other is result‐oriented. We derive conditions under which both tax systems lead to socially optimal strategies. We show that a result‐oriented scheme needs less information on farmers' time preferences.

[hal-05491715] Fromage de Comté et vache montbéliarde : des communs aux effets protecteurs ?
Cet article décrit l’imbrication de deux communs ancrés dans le territoire du massif du Jura : le fromage Comté et les savoir-faire qui entourent sa fabrication ; la vache montbéliarde, à la fois objet de passion et de sélection génétique de pointe. Chacun d’eux a des effets en termes de protection sociale : le succès contemporain de l’AOP Comté confère une vitalité économique à l’agriculture et au territoire. La vache montbéliarde, dont la sélection échappe désormais aux éleveurs dans une mondialisation de la génétique, continue de faire passion et de nourrir des satisfactions dans le métier d’éleveur. Ces communs sont des productions matérielles et immatérielles, pétries d’ambivalences, mais qui assurent néanmoins une sécurité et une protection par le bas, par les agriculteurs, les acteurs de la filière et du territoire. Notre détour historique et géographique permet de revisiter la notion de protection sociale et d’interroger la protection environnementale, sans laquelle la durabilité sociale et les communs seraient menacés.

[hal-04681561] The implementation of the new Common Agricultural Policy in France will not be environmentally ambitious
This paper assesses the environmental ambition of 2023-2027 Common Agricultural Policy in France. Since conditionality and agri-environment-climate measures are only marginally improved relative to the previous period, attention is focused on the new environmental instrument of the eco-scheme that in France targets the whole farm. Results suggest low environmental progress since almost all French farms would reach the standard level of the eco-scheme by one of the three access paths with unchanged farming practices, and 85% of them would reach the superior level. The percentage of farms at the superior level would be lower for farms specialized in annual crops than for cattle farms. We then show that the payment difference of e20 per hectare between the standard and superior level is probably insufficient for farms specialized in cereals, oilseeds and protein crops to offset the additional cost of the change in farm practices required to move from the standard to the superior level.

[hal-05570603] Hiérarchie et centralités d'équipements et de services
Ce chapitre analyse la centralité à partir de l’offre locale de commerces et services. À partir de la base permanente des équipements (BPE, 2017), 10 774 centres sont identifiés et hiérarchisés à l’échelle communale selon une classification automatique mixte, distinguant quatre niveaux (local, intermédiaire, structurant, majeur) sans recours à des seuils exogènes. Les résultats montrent que 31 % des communes concentrent 87 % de la population et organisent l’accès aux services selon une hiérarchie emboîtée. La centralité repose sur la coprésence de paniers d’équipements plutôt que sur la seule taille démographique ou l’emploi. Les aires de desserte révèlent une organisation territoriale combinant configurations monocentriques et polycentriques. L’analyse met en évidence de fortes disparités de fragilité, particulièrement dans les centres isolés des espaces peu denses, soulignant l’intérêt d’une approche par les services pour éclairer les politiques territoriales.

[hal-05318202] Critical material and regional inequality: Material demand under diverging decarbonization pathways in China’s power sector
China's power sector decarbonization is crucial for global climate goals. However, regional disparities in decarbonization pathways and material demands arise due to differences in resource endowment, economic development, and policy support. This study develops an integrated assessment model to evaluate critical material demand for decarbonizing China's power sector under four scenarios: Business-as-Usual (BAU), Renewable Energy (RE), Carbon Capture and Storage (CCS), and Advanced Nuclear (AN). The results show significant provincial variations, with eastern provinces favoring wind and solar, while western and coal-dependent regions rely on hydropower or CCS. Nationally, material demand peaks in the CCS scenario by 2060, especially for structural materials like copper (2250 Mt) and nickel (445 Mt). Functional materials such as silicon and indium see significant demand increases under PV-driven transitions, with silicon reaching 9300 kt and indium 14.2 Mt by 2060 in the RE scenario. These findings highlight the need for region-specific policies, long-term material supply planning, and addressing material demand imbalances for a sustainable energy transition.

[hal-05454974] ‘PULSE FICTION’: Development of Slightly Processed Pulse-Based Foods and Recipes to Meet the Needs of Consumers and the Agricultural Sector and Improve Food Sustainability
Pulses offer significant nutritional and environmental benefits and are useful components of healthier, more sustainable diets and global food security. However, their consumption in France remains low and below the world average. Farmers face economic and technical challenges in diversifying crops, and current domestic production is insufficient to meet this low demand, resulting in continued reliance on imports. Production and consumption are closely linked: low consumer demands limit incentives for farmers to expand cultivation, while limited availability can also constrain uptake. One of the major barriers to consumption relates to preparation and processing. While consumers generally view raw or minimally processed pulses positively, they often avoid using them because they perceive them as time‐consuming to prepare or associate them with undesirable sensory attributes (e.g., bitterness and astringency). It also might be difficult for consumers to categorize pulses according to their level of processing. Although pulse processing makes them more convenient for users, former studies suggest that consumers are suspicious about the processing of pulses, and that they may even confuse processing with ultra‐processing. This suspicion could sometimes lead to rejection by consumers. The process should thus remain moderate. Encouraging the use of minimally processed pulses, which balance convenience and acceptance, is crucial for wider adoption. The aim of the PULSE FICTION project is to develop minimally processed pulse products with pulses as the main ingredient that align with consumer preferences, farmer constraints and sustainability goals. A key innovation will be the selection of intermediate food products (IFPs) on the basis of consumer and farmer input and chef‐developed easy‐to‐make recipes. These products will be evaluated for their nutritional and sensory qualities, satiety, consumer acceptance and environmental impact. Beyond product development, PULSE FICTION explores the cognitive and sensory factors influencing consumer acceptability and designs effective communication strategies for all stakeholders to facilitate consumer adoption of pulse‐based foods.

[hal-05527207] Econométrie des données spatiales : enjeux d'identification et perspectives
Cet article propose un point d’étape sur l’économétrie des données spatiales en mettant l’accent sur les enjeux d’identification des interactions spatiales et les perspectives ouvertes par le développement des données massives géolocalisées. Ce champ de l‘économétrie a pour objectif l’analyse des phénomènes où la proximité géographique, les interdépendances spatiales et les hétérogénéités territoriales jouent un rôle structurant. Si les modèles habituels, tels que le SAR ou le SDM, permettent de formaliser les interactions spatiales, leur mise en œuvre empirique soulève des difficultés d’identification majeures. Identifier rigoureusement ces interactions suppose de clarifier la nature des interactions, de traiter les problèmes d’endogénéité et de contrôler les sources d’hétérogénéité spatiale. L’article discute ensuite les défis que doit relever les méthodes de l’économétrie des données spatiales tant dans une perspective méthodologique structurelle que dans le cadre des modèles d’inférence causale, tout en intégrant les méthodes d’inférence développées dans d’autres branches de l’économétrie. Notamment, il souligne que l’essor du big spatial data et des algorithmes de spatial machine learning constituent une opportunité décisive pour dépasser certaines limites des approches traditionnelles.

[hal-05558834] Choosing Right Bayesian Tools: A Comparative Study of Modern Bayesian Methods in Spatial Econometric Models
We compare three modern Bayesian approaches, Hamiltonian Monte Carlo (HMC), Variational Bayes (VB), and Integrated Nested Laplace Approximation (INLA), for two classic spatial econometric specifications: the spatial lag model and spatial error model. Our Monte Carlo experiments span a range of sample sizes and spatial neighborhood structures to assess accuracy and computational efficiency. Overall, posterior means exhibit minimal bias for most parameters, with precision improving as sample size grows. VB and INLA deliver substantial computational gains over HMC, with VB typically fastest at small and moderate samples and INLA showing excellent scalability at larger samples. However, INLA can be sensitive to dense spatial weight matrices, showing elevated bias and error dispersion for variance and some regression parameters. Two empirical illustrations underscore these findings: a municipal expenditure reaction function for Île-de-France and a hedonic price for housing in Ames, Iowa. Our results yield actionable guidance. HMC remains a gold standard for accuracy when computation permits; VB is a strong, scalable default; and INLA is attractive for large samples provided the weight matrix is not overly dense. These insights help practitioners select Bayesian tools aligned with data size, spatial neighborhood structure, and time constraints.

[tel-05454325] Incentives to improve the nutritional and environmental quality of diets : effectiveness, compliance, and measurement challenges, informed by randomized controlled field trials
This thesis evaluates the effectiveness of incentives aimed at promoting healthier, low-carbon diets through randomised controlled trials conducted in the Dijon metropolitan area. The first chapter analyses a food voucher scheme targeting fruit, vegetables and pulses, with the amount calibrated to meet the recommendation of five portions of fruit and vegetables per day. The results indicate an average increase of 29% in the purchase of healthy plant-based products, reaching 61% when automatic checkout checks are applied. Overall, the nutritional quality of diets is improving, but calorie intake and the carbon footprint of food remain broadly stable. Finally, when automatic checkout checks are active, the intervention proves to be cost-effective, with 53% of the amounts distributed contributing directly to increased purchases of targeted products. In Chapter II, we show that adding a ‘eating well on a budget’ training course to the subsidy scheme has no additional effect on increasing the supply of healthy plant-based products. Nevertheless, the implementation of these workshops is still recommended as they remain inexpensive in the long term. Chapter III shows that food frequency questionnaires are weakly correlated with supply data. Chapter IV presents the results of an experiment with nudges in social grocery stores, the results of which lack robustness because the parallel trends assumption is not met.

[hal-05315123] PARIS2019: The impact of rent control on the Parisian rental market
We evaluate the impact of the rent control regulation implemented by the city of Paris in July 2019 on the Parisian rental market. We take advantage of the large amount of real-time data available on the SeLoger platform containing the ads published by professional realtors. Using a database of 559,300 observations from January 2018 to June 2023, we apply a difference-in-differences model, where control units are located in eight major French cities in which the rental market is particularly tense but not regulated during the analysis period. We show that the rent control policy decreased rents by 3.7% to 4.2% in Paris on average. Yet, the effect of the policy is heterogeneous depending on dwelling characteristics, with a stronger effect on small apartments. We also estimate the upper bound of the effectiveness of the policy and show that if every dwelling respected the rent control, rents would have decreased by 8.2% to 8.7%. We confirm the effectiveness of the rent control policy by extending the analysis to five additional regulated cities using a staggered difference-in-differences strategy, which reinforces the external validity of our findings. Finally, we examine whether the policy affected the supply of rental housing, proxied by the number of new listings published by agencies. We find no evidence of a decline in supply attributable to the rent control

[hal-05107904] Identification of Spatial Spillovers: Do's and Don'ts
The notion of spatial spillovers has been widely used in applied spatial econometrics. In this paper, we consider how they can be identified in both structural and causal reduced‐form models. First, discussing the various threats to identification in structural models, we point out that the typical estimation framework proposed in the applied spatial econometric literature boils down to considering spatial spillovers as a side‐effect of a data‐driven chosen specification. We also discuss the limits of blindly relying on interaction matrices purely based on geography to identify the source and content of spillovers. Then, we present reduced forms impact evaluation models for spatial data and show that the current spatial versions of usual impact evaluation models are not fully satisfactory when considering the identification issue. Finally, we propose a set of recommendations for applied articles aimed at identifying spatial spillovers.

[hal-05478931] Structural Change in Rural West Africa: Does Mobile Banking Have a Role to Play?
Non-farm entrepreneurship plays a vital role in mitigating climate shocks and strengthening household resilience in rural sub-Saharan Africa, yet liquidity constraints often hinder business creation. This study examines whether mobile banking promotes rural non-farm entrepreneurship in seven WAEMU countries—Burkina Faso, Côte d’Ivoire, Guinea-Bissau, Mali, Niger, Senegal, and Togo. Using panel data from the 2018/19 and 2021/22 waves of the Enquête Harmonisée sur les Conditions de Vie des Ménages (EHCVM), we address potential endogeneity in mobile banking adoption through correlated random effects models, entropy balancing, and instrumental variable estimation. Across all specifications, mobile banking users are significantly more likely to operate non-farm enterprises. Mechanism analysis shows that mobile banking enhances financial inclusion by increasing access to formal financial institutions and participation in informal savings groups, such as ROSCAs. These findings underscore the role of mobile banking in promoting rural structural transformation and improving economic resilience in WAEMU countries.

[hal-05362187] Setting reference GHG emissions for research activities
The carbon footprint of academic research has attracted growing attention in recent years, with numerous assessments conducted at the level of universities or research departments. Yet, methodological inconsistencies and small sample sizes limit comparability and hinder generalization, while concrete mitigation targets remain underdeveloped. This study draws on a national database covering about 157,000 research staff in 700 units-roughly one-third of French public research-between 2019 and 2023. Emissions are assessed across five major sources: purchases, professional travel, commuting, electricity, and heating. The dataset is used to (i) model structural determinants of research-related GHG emissions and (ii) establish reference values to guide mitigation strategies. We develop a framework to identify robust statistical models to predict average emissions levels per source. Based on staff composition, supervisory body, research domain, and geographical location, these models explain up to one-third of inter-unit variance and improve predictive accuracy by 8%–23% over baseline averages. Embedded in an online tool, these models help support the design of efficient, equitable, and realistic mitigation targets.

[hal-04271386] Discrimination against people with mental, physical or visual disabilities in the French rental housing market: field experiment
We implement correspondence testing to detect and assess the extent of discrimination against people with disabilities in the French rental housing market. By sending 1,750 emails in a matched-pair procedure, we provide evidence of significant and extensive discrimination against blind people with a guide dog, individuals with mental disabilities, and individuals with motor impairments in the process of rented housing allocation. However, the primary cause of discrimination against blind individuals appears to stem from the presence of the guide dog, rather than the disability itself. Our results are also consistent with the presence of statistical discrimination (particularly based on financial means). We find that absolute discrimination against disabled applicants increases in accordance with the level of rent, while real estate agents discriminate significantly less against disabled applicants than private landlords.

[hal-05307641] Is there an additional price premium for single-family houses exposed to urban parks? Insights from causal spatio-temporal matching in Québec city
Urban parks and green spaces are known for providing positive social and environmental services, which is usually capitalized into real estate prices. While positive externalities extend at the neighbourhood level, negative externalities can be detected close to the infrastructures, making the price premium varying locally for houses exposed. The paper investigates if local price premium for exposition to different types of parks differ between houses connected or adjacent to parks compared to other houses located nearby but not directly exposed. For that purpose, a spatio-temporal propensity score matching identification strategy is proposed and applied on single-family house transactions in Québec City between 2004 and 2020. The estimation results show that, except for two specific situations, direct exposition does not necessarily translate in significant additional house price premiums. However, a complementary quantile analysis suggests that the non-significant mean differential price premium hides an important spatial dimension, pointing to the presence of environmental inequities.
