Self-Revealing Renegotiation
No full textWe revisit the tension between the legal doctrine of renegotiation and economic efficiency. We introduce self-revealing mechanisms that combine bidirectional communication (the agent sends and receives information) with conditional disclosure (communication remains private during renegotiation but becomes verifiable at contract execution). In the canonical Fudenberg and Tirole (1990) framework, we design a self-revealing mechanism that fully mitigates the renegotiation threat by uniquely implementing the second-best allocation. Thus, the construction achieves the full-commitment outcome while satisfying renegotiation-proofness. Our optimal mechanism is structurally simple, and exploits signal disclosures to the agent to
construct incentive-compatible off-path punishments, which she activates after observing a renegotiation offer. It verifies standard commitment assumptions by only conditioning decisions on public information, without requiring any third-party enforcement. In practical terms, it can be implemented with existing smart-contract techniques. Our results extend to general settings of renegotiation

Capturing the positive effects of brain drain through return migration policies: An analysis of the 1980-2022 Moroccan experience
No full textThe emigration of highly educated and skilled individuals from low- and middle- to high-income countries has often been synonymous with human capital losses for the countries of origin, a phenomenon known as "brain drain" (Bhagwati and Hamada, 1974). However, under some conditions, these losses can be offset by human capital formation in the source countries precisely due to emigration. In this case, one talks about "beneficial brain drain" and this phenomenon has been coined "brain gain" (Stark et al., 1997, 1998). Using data on the Kingdom of Morocco covering the 1980-2022 period, we investigate the extent to which the government drew economic benefits from an important population of Moroccans living abroad by implementing return migration policies. More specifically, we explore the effects of measures targeting the Moroccan diasporas and their contributions to the Kingdom's economy on (i) the attractiveness of the Kingdom for foreign investors; (ii) the quality and capacity of the country's commercial air and maritime transport infrastructure; and (iii) the level of modernization of its public administration.
The data analysis shows that these measures had a positive impact on each of these key dimensions of development, suggesting that this type of policies can be effective in capturing some of the "brain gain" effects that have been highlighted in the empirical literature on the relationship between emigration and development in developing countries (Beine et al., 2001, 2008; Batista et al., 2025)

No full textChronique de répression administrative fiscale (juillet – décembre 2025)
No full textCette chronique a pour ambition de présenter, de manière synthétique, quelques-unes des décisions de jurisprudence, rendues entre le 1er juillet et le 31 décembre 2025, revêtant un intérêt particulier en matière de répression administrative fiscale.
Est notamment abordée la répression du dépôt tardif des actes et déclarations en cas d’altération des facultés mentales du contribuable, de la combinaison des manquements déclaratifs et de la bonne foi, mais également des manquements aux règles de facturation et aux obligations de coopération. Sont aussi abordées la conventionnalité de la majoration de 25 % du 7 de l’article 158 du CGI ainsi que plusieurs décisions, portant sur la modulation des punitions administratives et la rétroactivité in mitius, qui ont renforcé les droits de la personne sanctionnée en matière fiscale
