Thierry Kamionka, Sandrine Spaeter
Using novel data linking administrative labor market information of German Democratic Republic (GDR) workers before and after reunification, I investigate occupational mobility during the “Wende” (1989-1992). I compare GDR workers’ patterns with Federal Republic of Germany (FRG) workers from the same birth cohort. The results indicate diverse occupational mobility facets, including upgrading and downgrading. Notably, GDR workers exhibited much higher occupational mobility dynamics than the corresponding FRG cohorts. Regarding transitions to non-employment, the oldest cohort (aged 58-60 in 1989) drives the aggregate figures in both parts of Germany, reflecting the widespread application of early retirement schemes at the time.
Minimax regret et jeu de demande 11-20
Gisèle Umbhauer
Arad and Rubinstein’s 11–20 money request game nicely triggers level-k reasoning. We show, in a general class of money-request games, that mixed-strategy minimax regret plays a significant role too, and that it mimics level-k reasoning, at least if the number of level-k players in a population is supposed to decrease in k. We also show, in this class of games, an original link between the minimax regret probability distribution and the mixed-strategy Nash equilibrium distribution, and we compare the payoffs obtained with both concepts.
Aides formelles et informelles pour les seniors : substituabilité ou complémentarité ?
Liliane Bonnal, Pascal Favard, Thomas Maurice
From the data of the 8th wave of the SHARE (Survey on Health, Ageing and Retirement) survey, we investigate the use of home care by elderly individuals in Europe. These aids could be utilized by an elderly person because they are unable to perform certain household or personal tasks. We simultaneously estimate the probabilities of receiving formal and informal assistance and the number of hours of formal assistance received, taking into account the reciprocal interactions between these forms of help. We show that the relationship is significantly negative, but it is not sufficient to conclude that formal care is a substitute for informal care since these aids represent an aggregation of heterogeneous services. We conduct a differentiated study based on whether the assistance is domestic or personal. By considering more homogeneous services, the substitutability is strongly established.

Does the Adoption of Environmental Contracts Affect Farms’ Productivity and Efficiency?
Marie Lassalas, Alejandro Plastina, Sergio H. Lence
The Common Agricultural Policy (CAP) must meet increasingly ambitious environmental objectives while ensuring food supply and farmers’ income. We assess the impact of two instruments implemented in the CAP, agri-environmental schemes (AES) and organic subsidies, on farms’ productivity and efficiency. We apply a stochastic frontier model and a difference-in-differences estimator to data on French farms specialized in crop production. Our results suggest that the adoption of AES and organic farming has no effect on farms’ productivity and efficiency regarding their own production frontier. When compared to the entire sector, results show a negative causal effect of the adoption of organic practices on farms’ efficiency between 2014 and 2020. Organic farms operate under a lower production frontier than conventional and AES farms regarding the metafrontier.
Mécanismes centralisés ou décentralisés dans les équipes de travail : une approche expérimentale
Marc Lebourges, David Masclet
This paper presents evidence from a laboratory experiment comparing different incentive mechanisms for team work: centralized (target-based and team tournament) and decentralized (peer-pressure), or revenue sharing, which constitutes our baseline treatment. We observe free-riding in the baseline treatment, albeit not as severe as theoretically-predicted. Peer pressure partly limits free-riding but is costly for workers. Target-based schemes lead to near-Pareto levels of effort and high firms’ profits but provide relatively lower workers’ payoffs. Finally, team tournaments generate high efforts but also high payoff inequalities among workers.

L’autoprotection influence-t-elle les choix d’assurance des individus ? Une étude expérimentale
Claire Mouminoux, Morgane Plantier et Jean-Louis Rullière
Based on lab experiment, this study analyzes whether introducing a self-protection mechanism to reduce the loss probability affects individuals’ insurance choices. The experimental evidence shows that the possibility of a posteriori self-protection encourages policyholders to choose lower levels of coverage, which reveals their preference for self-protection to mitigate their risk. However, this attraction to self-protection option does not turn into real action revealing an inconsistency of choices: individuals who deliberately choose to be less insured when a self-protection option is available do not subsequently engage in more self-protection efforts afterwards.
