Felix Weinhardt (European University Viadrina) – Separate Housework Spheres
Mar 4 @ 11 h 00 – 12 h 15

Joint work with Jonas Jessen, Sebastian Schweighofer-Kodritsch, and Jan Berkes

Abstract: Using novel time-use data from Germany before and after reunification, we document two facts: First, spouses that both work full-time exhibit the same housework pattern whether they do so voluntarily or due to a full-time mandate, as in the GDR. Second, men’s amount of housework is the same regardless of their spouse’s labour supply. We theoretically explain this pattern by the presence of two household goods and socially learnt gender-specific comparative advantage in their home production. We label this gender specialisation as separate housework spheres. We find that separation occurs along the lines of more time-intensive routine (female) vs. less time-intensive non-routine (male) housework, and the presence of children further exacerbates the resulting housework gender-gap. Evidence from gendered parent-child interaction and teenagers’ time-use supports intergenerational transmission. We discuss implications for child penalties, effects of shocks such as COVID-19, and policy aiming for gender equality.

Alexandre Mayol (Université de Lorraine, BETA) – United we stand, divided we fall: Exploring the drivers of inter-municipal cooperation in water provision
Mar 5 @ 10 h 30 – 11 h 45

This article examines the determinants of inter-municipal cooperation in the drinking water sector in France. While the literature highlights the paradoxical effects of inter-municipal cooperation on economies of scale, this contribution offers new insights. Using a comprehensive panel of French water services from 2008 to 2021, we analyze through a Correlated Random Effects/Control Function specification, why municipalities refuse to merge and how they decide to do so. We first show that searching for better pricing and network improvement drives consolidation. However, we limit this result by exhibiting that the legal form chosen to cooperate, imposing varying degrees of freedom on municipalities in governance, impacts the determinants of joining.

Alexandre ANGELLOZ-NICOUD – Stocks price growth, a reason for the lack of inflation?
Mar 8 @ 13 h 00 – 13 h 30

Title Stocks price growth, a reason for the lack of inflation?
Abstract 
From 2008 to 2019, inflation has always been lower than money creation. However, according to the quantity theory of money, this situation is not possible on the long run. Over the same period, stocks valuation growth increased significantly. Therefore, a question arises: can rising stocks prices theoreticaly explain a low inflation?
In a New Monetarist environment (built on Lagos and Wright, 2005), I introduce a decentralized market for stocks. It generates a trade off between the demand for money to buy goods and the demand for money to buy stocks. In this model, under certain conditions, an increase in the money growth rate raises stock prices more than proportionally and generates inflation lower than the money growth rate. The growth in money supply could therefore have fuelled a rise in stocks prices instead of inflation.

Oihane Gallo (HEC, University of Lausanne) – Anonymity and strategy-proofness on a domain of single-peaked and single-dipped preferences
Mar 12 @ 10 h 30 – 11 h 45

We analyze the problem of locating a public facility on a line in a society where agents can have either single-peaked preferences or single-dipped preferences. We consider the domain analyzed in Alcalde-Unzu et al. (2023) where the type of preference of each agent is public information and both the location of the peaks/dips and the rest of the preference are unknown. We characterize all strategy-proof and anonymous rules on this domain. We first show the additional conditions anonymity imposes on the strategy-proof rules characterized by Alcalde-Unzu et al. (2023). We also provide an alternative “two-step characterization”: First, the median between the peaks and a collection of fixed values is computed (Moulin, 1980) and, as a result, either a single alternative or a pair of contiguous alternatives arise. If the outcome of the median is a pair, we apply a “double-quota majority method” in the second step to choose between the two alternatives of the pair (Moulin, 1983). Finally, we show the equivalence between the two characterizations.

Antoine Rolland (ERIC, Université Lyon 2) et Jean-Baptiste Aubin (ICJ, INSA Lyon) – De quelques méthodes de vote par évaluation
Mar 26 @ 10 h 30 – 11 h 45

Jean-Baptiste Aubin et Antoine Rolland, en collaboration avec Irène Gannaz et Samuela Leoni, poursuivent un programme de recherche visant à analyser les modes de scrutins fondés sur des évaluations, et non sur des classements (evaluation-based voting rules vs ranking-based voting rules). Après avoir proposé une modélisation et une généralisation des modes de scrutins par évaluation grâce aux fonctions de profondeur (“Deepest voting: A new way of electing,” Mathematical Social Sciences, 2022), et des modèles probabilistes pour les votes par évaluation (« Probabilistic Models of Profiles for Voting by Evaluation », soumis & sur HAL),  ils analysent de manière empirique les proximités entre méthodes de vote à partir des résultats des votes, et non à partir des propriétés ou des mécanismes de vote. Les premiers résultats de cette analyse seront présentés, en insistant sur le plan d’expérience et l’influence des différents facteurs sur la proximité entre méthodes de vote. Enfin, des travaux prospectifs seront présentés, en fonction du temps, sur la modélisation des modes de scrutins par évaluation à l’aide de la théorie du transport optimal, et sa généralisation possible aux modes de scrutins utilisant des classements ou encore sur un indice de qualité d’élection issu de ces techniques.
