[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.

[hal-05399129] FN-RN. Penser la banalisation de l’extrême droite
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.
