Seeing Through the Algorithm: How Explainability Shapes Decision-Making on Robo-Advisor Platforms

Date : Jeudi | 2025-05-22 Ă  12h30 Lieu : Salle des thĂšses Lien TEAMS : Cliquer ici pour rejoindre le sĂ©minaire doctorant du LÉO Mehdi LOUAFI (LEO, UniversitĂ© d’OrlĂ©ans) This paper examines how algorithmic explainability shapes user decision-making and engagement on a leading French robo-advisor platform. In a large-scale field experiment, we randomly assigned 4,646 prospective clients to one of two conditions: a treatment group that viewed a graphical breakdown of the factors driving their personalized risk-profile recommendation, or a […]

Forecasting Inflation Expectations with Adaptive Learning

Date : Jeudi | 2025-05-15 Ă  12h30 Lieu : Salle des thĂšses Lien TEAMS : Cliquez ici pour rejoindre le sĂ©minaire du LÉO Cyril DELL’EVA (UniversitĂ© de Rouen / LERN) Inflation expectations in the QPM are approximated with the BER Survey of Inflation Expectations. These are forecasted by using an exogenous AR(1) process, constrained to converge to the target at the two year horizon. The AR(1) process imposes strong judgment on the forecasting of inflation and it is unlikely to forecast […]

Carbon curse: As you extract, so you will burn

Date : Jeudi | 2025-04-24 Ă  12h30 Lieu : Salle des thĂšses Lien TEAMS : Cliquez ici pour rejoindre le sĂ©minaire du LÉO Adrien DESROZIERS (LÉO, UniversitĂ© d’OrlĂ©ans) The “Carbon Curse” theory suggests that fossil fuel richness leads countries to have more carbon-intensive development trajectories than they would otherwise. Using causal inference for cross-country panel data spanning 1950–2018, we globally estimate the effect of giant oil and gas discoveries on carbon emissions. Our findings show that the effect is sizable and […]

Trusting up: How Social Hierarchies shape Social Trust

Date : Jeudi | 2025-04-30 Ă  12h30 Lieu : Salle des thĂšses Lien TEAMS : Cliquez ici pour rejoindre le sĂ©minaire du LÉO Catherine BROS (LÉO, UniversitĂ© de Tours) This paper examines the impact of social hierarchy on trust dynamics within the Indian caste system, building on social identity theory. We find that higher castes enjoy a trust surplus from lower castes, which is only partially reduced when caste identity is emphasized. This asymmetrical trust premium is linked to the higher […]

Droughts and Agricultural Land Concentration in France

Date : Jeudi | 2025-03-27 Ă  12h30 Lieu : Salle des thĂšses Lien TEAMS : Cliquez ici pour rejoindre le sĂ©minaire du LÉO Raja CHAKIR (University of Paris-Saclay This paper investigates the impact of recurrent droughts on farm size and land concentration in France over both the short and long run. While much of the existing literature on climate shocks and landholding patterns focuses on developing countries—where extreme weather often drives cropland expansion as an adaptive response—evidence from developed economies remains […]

Analyse Ă©conomique des choix d’infiltrations des mĂ©nages agricoles dans les espaces protĂ©gĂ©es : cas des ForĂȘts ClassĂ©es en CĂŽte d’Ivoire

Date : Jeudi | 2025-03-13 Ă  12h30 Lieu : Salle des thĂšses Lien TEAMS : Cliquez ici pour rejoindre le sĂ©minaire du LÉO Ariane AMIN (UniversitĂ© FĂ©lix HouphouĂ«t-Boigny et Centre Suisse de Recherches Scientifiques en CĂŽte d’Ivoire) Dans la lutte contre la dĂ©forestation et la dĂ©gradation de la biodiversitĂ©, l’établissement d’aires protĂ©gĂ©es demeurent globalement une stratĂ©gie dominante en termes de politique publique. La progression de la dĂ©forestation au sein mĂȘme de ces espaces protĂ©gĂ©es dans certains pays malgrĂ© leurs statuts, se […]

Legislation, Regulation and Litigation: Demand for U.S. Legal Services in Historical Perspective”

Date : Jeudi | 2025-03-06 Ă  12h30 Lieu : Salle des thĂšses Lien TEAMS : Cliquez ici pour rejoindre le sĂ©minaire du LÉO Ariell RESHEF (Univ. Paris 1 PanthĂ©on-Sorbonne) The employment share of legal services in the U.S. more than doubled during 1970–1990, in stark contrast to stability during 1850–1970 and after 1990. The relative wage of lawyers and law firm partners also doubled between 1970 and 1990. We argue that this demand shift was driven by important legislative and regulatory […]

Evaluating the causal impact of Non-Tariff Measures on Global Value Chain trade: a quasi-experimental approach

Date : Jeudi | 2025-02-13 Ă  12h30 Lieu : Salle des thĂšses Lien TEAMS : Cliquez ici pour rejoindre le sĂ©minaire du LÉO Sylvia NENCI (University of Roma III) This work investigates the impact of Non-Tariff Measures (NTMs) on Global Value Chain (GVC) trade using a quasi-experimental approach to address non-linearities and endogeneity. Analyzing a panel dataset of NTMs and trade in value-added across 172 countries, with a focus on agriculture, the research finds that NTMs affect GVC trade non-linearly. Most […]

Within-group inequality and caste-based crimes in India

Date : Jeudi | 2025-01-30 Ă  12h30 Lieu : Salle des thĂšses Lien TEAMS : Cliquez ici pour rejoindre le sĂ©minaire du LÉO Sarmistha PAL (University of Surrey) We examine how within-group inequality, by influencing the group bias of state institutions such as the police and the judiciary, affects the cost-benefit calculus of individuals engaging in identity-assertive behaviour, that results in police complaints regarding hate crimes. We develop a two-stage contest model of between-group conflict, where the relative influence over state […]
