[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-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-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.

[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.

Les auteurs analysent la banalisation du FN-RN comme un processus social complexe, irréductible à la seule stratégie partisane ou aux comportements électoraux des classes populaires. En mobilisant une sociologie décloisonnée, ils montrent que cette banalisation repose sur une institutionnalisation fragile du parti, marquée par une professionnalisation inachevée et des fonctionnements organisationnels informels. Ils mettent en évidence le rôle décisif des espaces médiatiques, journalistiques et sondagiers, ainsi que celui des autres forces politiques, dans la légitimation progressive de l’extrême droite. Enfin, ils soulignent que la banalisation s’inscrit dans des pratiques ordinaires, locales et de long terme, qui routinisent les représentations de l’extrême droite au-delà du champ strictement politique.

[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-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.

[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-05335373] Les vignobles en construction : une analyse des ressources et de la structuration d’une action collective innovante et territorialisée
Face à la baisse de la consommation de vin et, plus largement, à une conjoncture économique défavorable, le vignoble français doit s’adapter à une double concurrence : celle des vins du Nouveau Monde (vins de cépages) et celle des « vins d’artistes », plus respectueux de l’environnement et portés par des stratégies de marques individuelles. Parallèlement, le changement climatique modifie les conditions de production, favorisant l’émergence de nouveaux vignobles dans des régions auparavant inadaptées, comme la Bretagne. Cette étude analyse la création d’un vignoble breton à travers le prisme de l’action collective territorialisée, en s’intéressant aux dynamiques d’innovations techniques, commerciales et organisationnelles. La méthodologie repose sur des entretiens semi-directifs et des observations participantes, l’objectif étant d’identifier les acteurs de l’émergence de la filière, leurs stratégies et les ressources mobilisées. Les résultats attendus incluent une typologie des acteurs, une frise chrono-systémique retraçant la trajectoire du vignoble, et une meilleure compréhension des modèles d’innovation et de gouvernance territoriale en construction.

Le système alimentaire actuel atteint des limites de soutenabilité environnementale économiques et sociales (Rastouin, 2024). En France, le Grenelle de l’environnement en 2007 promeut la mise en place des circuits courts et de proximité. Mais la demande finale reste trop limitée, les acteurs publics utilisent alors le levier de la restauration collective pour reterritorialiser le système alimentaire et améliorer la qualité nutritionnelle de l’alimentation. L’objectif de cette communication sera double : 1) analyser quelle a été l’activation des proximités organisées et géographiques par la restauration collective ? Cette activation a-t-elle contribué à la diffusion de l’innovation ? 2) La reterritorialisation a-t-elle contribué à créer des risques d’inégalités territoriales ? Nos résultats, fondés sur l’utilisation de la base de données Agrilocal, montrent que la diffusion de l’innovation reste limitée en Bourgogne Franche-Comté et que le Covid a ralenti la transition du système alimentaire.

En réponse aux préoccupations environnementales croissantes et à la recherche de ressources locales durables, cette étude examine l’émergence de micro-secteurs biosourcés à travers l’exemple de la valorisation de la laine de mouton en France. Traditionnellement considérée comme un déchet, en particulier lorsqu’elle provient de races à viande, la laine brute reste largement sous-exploitée en dehors de l’industrie textile. Pourtant, ses propriétés physico-chimiques offrent un potentiel prometteur pour des utilisations alternatives telles que l’isolation thermique et acoustique, le paillage agricole et les composites écologiques. S’appuyant sur une revue de la littérature et une étude de cas de Vert Laine, une start-up basée en Bourgogne, cette recherche explore la structuration de ces nouvelles filières, les acteurs impliqués et les obstacles auxquels ils sont confrontés. À l’aide du cadre de modèle d’affaire circulaire BM3C2, l’étude analyse les modèles économiques alignés sur les principes de l’économie circulaire. Elle vise à identifier les dynamiques d’innovation et les partenariats territoriaux nécessaires pour développer de telles initiatives. Cette recherche contribue au débat plus large sur les modèles de production durable, la valorisation des ressources locales et la transition vers une bioéconomie circulaire.

Dans un contexte d’adaptation au changement climatique et de transition agroécologique, cette communication analyse les changements de pratiques en matière de gestion de la matière organique des sols dans la viticulture bourguignonne. S’appuyant sur une enquête par entretiens semi-directifs menée auprès de 30 viticulteurs de Bourgogne, elle interroge les facteurs individuels, techniques, économiques et sociaux influençant l’innovation.

[hal-05321991] Assessing carbon dioxide emission reduction potential using a cost approach
Departing from traditional approaches that treat carbon dioxide (CO2) emissions as a bad output, therefore relying on the weak disposability assumption, this paper considers CO2 emissions as a cost to minimise, thus preserving the materials balance condition. In particular, we extend the pollution cost approach (Coelli et al., 2007) by evaluating peer countries on their carbon intensity per total energy consumption, in addition to their energy use. The proposed methodology is then applied to estimate the extent to which a selection of 33 OECD and BRICS countries can reduce their CO2 emissions, given their gross domestic products and populations over the 2001–2019 period. Our results indicate that the period mean reduction potential for CO2 emissions of 60 % (i.e. an efficiency level of 40 %) can be decomposed into a 33 % reduction in energy intensity and a 40 % decrease in the carbon intensity of energy (i.e. efficiencies of 67 % and 60 %, respectively).

[hal-05110567] Why do we keep killing crows? Farmers’ attachment to a controversial method in an attempt to protect their crops
Corvids are responsible for important damage to spring crops across western Switzerland and have become a significant concern for the farming community. Various prevention methods have been tested to reduce agricultural losses, but no suitable solution has been found. In an attempt to solve this problem, the Swiss farming community is asking the authorities, despite its relative unpopularity, to liberalize control shooting. However, the effectiveness of this control method has never been scientifically proven, and the few studies in ecology or conservation biology that question its efficiency are not considered by the farming community. This raises the question of why the attachment to an uncertain and controversial method is so strong. By bringing out the farming community's dominant representation of the problem of corvid damage and analyzing the stakeholder network dynamics, this article aims to highlight the social logics and multifactorial dimension of choosing a control method. We found that the fight against corvid damage is part of a more general conflict that pits the farming community against the rest of society on issues of ecology and production. Various social, cultural and cognitive logics lead the farming community to remain attached to control shooting, making a cognitive gamble that has no solid scientific basis. To succeed in getting farmers to abandon control shooting, three conditions must be met: the emergence of a replacement innovation, awareness of the negative practical, economic and ethical aspects of control shooting, and improved access to scientific knowledge on the subject in the farming world.

Our results demonstrate that the population size, the type of area (e.g., tourist, rural), and the waste pricing systems significantly influence eco-efficiency. These findings underscore the importance of tailoring local waste management policies to the specific characteristics and available resources of each area. They provide valuable insights for local authorities seeking to enhance eco-efficiency and optimize waste management practices. © 2025 The Authors

[hal-05384109] Towards a Safe and Just Operating Space for European Agriculture
Abstract This study proposes a monitoring framework for European agriculture within the Safe and Just Operating Space (SJOS) concept, integrating environmental thresholds, socio-economic considerations, and the objectives outlined in European Union (EU) policy frameworks. A thorough review of EU policies, including the European Green Deal (EGD), the Common Agricultural Policy (CAP), and related strategies, informed the adaptation of global SJOS concepts defined for the Planet and Humanity to the specific requirements of the EU agricultural sector. This downscaling to the regional contexts of the EU and the disaggregation to agricultural processes was central to ensuring the framework’s relevance and precision. The methodology identified over 30 indicator domains across 12 thematic areas, aligning global SJOS principles with EU policy targets. These indicators were refined through collaboration with modelling teams and external consultations, ensuring feasibility for use in existing simulation models. Workshops with experts and stakeholders revealed critical gaps, such as in biodiversity and animal welfare, highlighting areas for further model development. The framework enables projections of EU agriculture’s status relative to SJOS across various future scenarios, helping to analyse interdependencies, trade-offs, and synergies among objectives and indicators. The study emphasizes the importance of aligning scientific benchmarks with EU policy targets, including CAP and EGD objectives, while addressing challenges in data integration and interdisciplinary modelling.
