| Abstract: | In recent years, minimum wage policy in Europe has undergone a profound change: Many EU countries have raised their minimum wages above average and focused on the goal of ensuring an adequate standard of living. A consolidation of the new course is now emerging, as EU countries are now increasingly basing their minimum wage calculations on reference values as recommended in the European Minimum Wage Directive. The Directive was recently found to be fundamentally in compliance with European law by the European Court of Justice. In Germany, the Minimum Wage Commission has significantly increased the minimum wage and is now pursuing the goal of reaching 60% of the median wage. However, as the reference value has not yet been enshrined in law, progress in this country is still on shaky ground. |
| Abstract: | In den vergangenen Jahren hat die Mindestlohnpolitik in Europa einen tiefgreifenden Wandel erlebt: Die Mindestlöhne wurden deutlich angehoben und auf das Ziel ausgerichtet, einen angemessenen Lebensstandard zu sichern. Inzwischen zeichnet sich eine Konsolidierung des neuen Kurses ab: Viele EU-Staaten orientieren sich bei der Bemessung der Mindestlohnhöhe mittlerweile an Referenzwerten, wie sie in der Europäischen Mindestlohnrichtline empfohlen werden, die unlängst vom Europäischen Gerichtshof für grundsätzlich europarechtskonform erklärt wurde. In Deutschland hat die Mindestlohnkommission den Mindestlohn deutlich erhöht und verfolgt nun das Ziel, 60% des Medianlohns zu erreichen. Da eine gesetzliche Verankerung des Referenzwerts noch aussteht, steht der Fortschritt hierzulande allerdings auf tönernen Füßen. |

| Abstract: | A binding minimum wage can raise the regulated firm's profits when labor-market power interacts with product-market competition. We develop a duopoly model in which firms compete in the same product market but hire workers from distinct, geographically segmented labor markets. Because the minimum wage applies only to one firm's labor market, it does not directly raise its rival's costs. With monopsony power, the minimum wage reduces the regulated firm's marginal cost and induces it to expand output, forcing its rival to contract through strategic interaction. Under Cournot competition, this mechanism also increases total employment and consumer surplus. |

| Abstract: | Der vorliegende Report untersucht systematisch, welche wirtschaftlichen Effekte die Unternehmensmitbestimmung hat. Grundlage ist ein zweistufiges Rechercheverfahren, aus dem nach Bereinigung 384 wissenschaftliche Publikationen mit Schwerpunkt auf der Unternehmensmitbestimmung resultieren. Aus diesem Fundus wurden 63 quantitative Studien identifiziert, die die Effekte der Unternehmensmitbestimmung berechnen. Diese Forschung ist international geprägt: 40 % (25) der Studien stammen von Autor*innen an ausländischen Einrichtungen (vor allem USA), 68 % (43) sind englischsprachig. Der wissenschaftliche Diskurs wird zu über 80 % von Ökonom*innen bestimmt, interdisziplinäre Arbeiten sind selten. Die quantitative Forschung konzentriert sich auf die paritätische Mitbestimmung: 86 % (54) der Arbeiten untersuchen die paritätische Mitbestimmung, 75 % (47) die Drittelbeteiligung und 13 % (8) die Montanmitbestimmung. Insgesamt kommen 33% (21) der Studien zu positiven Effekten der Unternehmensmitbestimmung, weitere 33% (21) berechnen weder positive noch negativen Effekte (neutral), 14% (9) positive und negative Effekte und 19% (12) kalkulieren negative Effekte. Nur knapp ein Fünftel der Studien kommt demnach zum Ergebnis, dass die Unternehmensmitbestimmung negative Wirkungen hat, wobei das vor allem für die Kapitalmarktbewertung gilt. Hinsichtlich Innovationen, Investitionen und wirtschaftliche Leistungs- bzw. Erfolgskennzahlen, wie Produktivität, Rentabilität und Profitabilität, kommt die Forschung zum Schluss, dass es mehrheitlich positive oder zumindest neutrale Effekte der Mitbestimmung gibt. |

| Abstract: | Les bouleversements de l'Anthropocène font peser des risques existentiels sur les sociétés humaines et les organisations sociales et menacent l'habitabilité de la planète. Pour atténuer ces risques et contribuer à stabiliser les dérives environnementales, les organisations publiques et privées peuvent s'engager dans un effort d'anticipation des futurs possibles à l'horizon moyen et long-terme. Ce type de démarche prospective peut les aider à identifier et s'engager dans des transformations à la fois ambitieuses et concrètes. Les approches, méthodes et outils de modélisation et de scénarisation destinés aux décideurs doivent désormais intégrer de manière native et systémique les contraintes environnementales qui pèsent sur la capacité des acteurs à se projeter dans le futur et à agir à partir des enseignements qu'ils peuvent en tirer. Cependant, de nombreux défis, à la fois épistémologiques, théoriques et méthodologiques doivent être relevés pour y parvenir. Pour y répondre, il est essentiel de questionner ces outils, leur conception et leurs applications. La transdisciplinarité de cette réflexion est donc plus que jamais essentielle car il s'agit de faire dialoguer différentes disciplines afin de consolider des cadres et des méthodes adaptés pour concevoir des stratégies et des prises de décision cohérentes et qui contribuent à préserver l'habitabilité de la planète. C'est à cette fin que le séminaire scientifique "From Modeling to Strategic Decision-Making Facing Planetary Boundaries" a réuni pendant cinq jours à l'École de Physique des Houches près de 70 contributeurs, à la fois chercheurs des différentes disciplines concernées par ces enjeux (sciences du système Terre, macroéconomie, ingénierie de modélisation, prospective, sciences de gestion, design, sociologie, géopolitique) et praticiens travaillant directement avec ces outils. Ce séminaire a cherché à explorer aussi largement que possible ces questions et à créer les synergies nécessaires pour y répondre. Nous remercions nos sponsors pour avoir rendu cet événement possible. Nous remercions également l'École de Physique des Houches pour son accueil. Bien que le sujet s'écarte de son champ d'étude traditionnel, cette institution poursuit sa tradition d'ouverture et se concentre sur des questions fondamentales cruciales pour l'avenir de nos sociétés. |

| Abstract: | A new 70-year dataset of world macroeconomic cycles reveals that the growing synchronisation of world economies mainly concerns asset prices. In contrast, the global synchronisation of variables such as GDP and credit remains low. Indeed, this “decoupling” has widened since the global financial crisis. We draw lessons from this for the conduct of public policies. <p> Une nouvelle base de données macroéconomiques internationales sur 70 ans permet d’établir que la synchronisation croissante des économies mondiales concerne surtout les prix des actifs. Des variables telles que PIB et crédit restent faiblement synchronisées au niveau mondial. Ce "découplage" s’est même accentué après la crise financière mondiale. Nous en tirons des enseignements pour la conduite des politiques publiques. |

| Abstract: | This paper shows that schools can foster the transmission of civic virtues by helping students to develop concrete, democratically chosen, collective projects. We draw on an RCT implemented in 200 middle schools in three countries. The program leads students to conduct citizenship projects in their communities under the supervision of teachers trained in the intervention. The intervention caused a decline in absenteeism and disciplinary sanctions at school, alongside improved academic achievement. It also led students to diversify their friendship network. The program has stronger effects when implemented by teachers who are initially more involved in the life of the school. |

| Abstract: | Access to the labor market is crucial for the economic integration of asylum seekers. This study estimates the causal impact of work authorization timing on the labor market outcomes of likely asylum seekers. We link USCIS administrative records with American Community Survey microdata and use congestion-driven variation in processing times within an instrumental variable framework. Faster authorization boosts labor force participation, employment, and earnings, while effects on hours worked and occupational choices are modest. The impacts are concentrated within the first decade after arrival and diminish over time, indicating that processing delays slow integration but do not permanently hinder it. |

| Abstract: | In European day-ahead electricity markets, carbon allowance costs passed through by marginal fossil plants raise consumer expenditure and generate inframarginal rents for non-emitting generators. We propose a settlement modification: when the zonal day-ahead price exceeds a threshold, non-emitting generation is remunerated at the clearing price minus a fixed CO2 proxy deduction, while all other units continue to receive the uniform price. The mechanism thus reallocates a part of the inframarginal rents to consumers. Using hourly data we estimate static average expenditure reductions of about 8.5% in Austria and 4.7% in Germany in 2025. We discuss bidding incentives around the threshold, interactions with Contracts for Difference, implementation in coupled bidding zones, and a gas-cost variant for the 2022 energy crisis. |

| Abstract: | Time-of-use pricing is promoted to manage demand at public EV charging stations, yet its effectiveness depends on short run flexibility and local constraints. Using station by day by hour data from Shenzhen and Amsterdam, we estimate intraday price responsiveness on two margins, whether charging occurs in a station hour and, conditional on charging, delivered energy and occupancy time. High dimensional fixed effects absorb station by day demand shocks and hour of week patterns, so identification relies on within station, within day price variation under scheduled tariffs. Responses differ across cities. Shenzhen adjusts mainly through conditional intensity, whereas Amsterdam adjusts mainly through participation. Weather shifts responsiveness in opposite directions, with heat weakening responses in Shenzhen and rainfall strengthening participation responses in Amsterdam. Power upgrades typically outperform network densification except in transit-oriented areas. |

| Abstract: | Existing AI governance instruments provide essential foundations for oversight, with strong capabilities for harms that can be detected, bounded, attributed, and substantially remediated after the fact. This paper examines how that architecture can be further specified for three categories of AI-mediated outcome where restorability can fail under identifiable conditions: epistemic contagion through synthetic misinformation, reputational destruction via AI-generated defamation, and structural labor displacement driven by automation at scale. Through comparative regulatory analysis of four core Euro-Atlantic frameworks (the EU AI Act, the NIST AI RMF, the UK White Paper, and the OECD incident-reporting framework), with the G7 Hiroshima Code used as an interoperability reference, the paper identifies an opportunity for additional operational specification: an explicit threshold for the point at which remediation should be complemented by additional ex ante safeguards. It proposes the Systemic Irreversibility Baseline as that complementary layer. The Baseline routes responses along distinct tracks: standard remediation for restorable product-side harms, strict liability for localized irreversible product-side harms, precautionary technical architecture for systemically irreversible productside harms, and macroeconomic transition policy for intended-utility displacement. Four design mandates operationalize the precautionary track: traceable human oversight, auditable uncertainty thresholds for bounded decision tasks, epistemic user-interface friction, and contentprovenance infrastructure. Throughout, "effectively irreversible harm" denotes harm for which restoration to functional equivalence is not feasible within governance-relevant time horizons. The contribution is a governance design framework grounded in existing empirical literatures and comparative legal analysis, intended to complement current regulatory systems rather than replace them. |

| Abstract: | We present FinRL-X, a modular and deployment-consistent trading architecture that unifies data processing, strategy construction, backtesting, and broker execution under a weight-centric interface. While existing open-source platforms are often backtesting- or model-centric, they rarely provide system-level consistency between research evaluation and live deployment. FinRL-X addresses this gap through a composable strategy pipeline that integrates stock selection, portfolio allocation, timing, and portfolio-level risk overlays within a unified protocol. The framework supports both rule-based and AI-driven components, including reinforcement learning allocators and LLM-based sentiment signals, without altering downstream execution semantics. FinRL-X provides an extensible foundation for reproducible, end-to-end quantitative trading research and deployment. The official FinRL-X implementation is available at https://github.com/AI4Finance-Foundation /FinRL-Trading. |

| Abstract: | Do earthquakes strengthen social cohesion or undermine it? While some theories suggest they strengthen social bonds, others suggest they lead to social disintegration. We add to the limited causal evidence on this phenomenon using the 2012 Northern Italy earthquake, and exploit a unique dataset that captures different earthquake characteristics and multiple dimensions of social cohesion through behavioral measures. Difference-in-differences and event-study estimates show that the earthquake shifted behavior toward individualism and out-group hostility, and that short-run increases in linking social capital were followed by later erosion. Critically, dwelling damage had stronger and more persistent effects than the physical shaking, suggesting that visible, measurable destruction has a more profound impact on social cohesion. These findings further advance our understanding by demonstrating that different dimensions of social cohesion respond differently to earthquakes, with varying recovery patterns depending on earthquake characteristics. |

| Abstract: | For simultaneous independent events with finitely many outcomes, consider the expected-utility problem with nonnegative wagers and an endogenous cash position. We prove a short support theorem for a broad class of strictly increasing strictly concave utilities. On any fixed support family and at any optimal portfolio with positive cash, summing the active first-order conditions and comparing that sum with cash stationarity yields the exact identity \[ \frac{\lambda}{K_{\ell}^{(U)}}=\frac{1-P_{\ell, A}}{1-Q_{\ell, A}}, \] where $P_{\ell, A}$ and $Q_{\ell, A}$ are the active probability and price masses of event $\ell$, $\lambda$ is the budget multiplier, and $K_{\ell}^{(U)}$ is the continuation factor seen by inactive outcomes of that event. Consequently, after sorting each event by the edge ratio $p_{\ell i}/\pi_{\ell i}$, the exact active support is the eventwise union of the single-event supports, and this support is independent of the utility function. The single-event utility-invariant support theorem is already explicit in the free-exposure pari-mutuel setting in Smoczynski and Miles; the point of the present note is that the simultaneous independent-events analogue follows from the same state-price geometry once the right continuation factor is identified. |

| Abstract: | We study the upper hedging price for contingent claims in market models with strong types of arbitrage: increasing profit, strong arbitrage, and arbitrage of the first kind. The existence of arbitrage may make the price smaller than if it did not exist. For example, when the asset price process has a reflecting boundary, which introduces increasing profit in the market model, the option prices are reduced to those of the corresponding options that knock-out at the boundary. Furthermore, we demonstrate that corporate stock price processes with increasing profit are obtained as a result of corporate stock issuance and repurchase plans. |

| Abstract: | There is emerging evidence that trust-region (TR) algorithms are very effective at solving derivative-free nonconvex stochastic optimization problems in which the objective function is a Monte Carlo (MC) estimate. A recent strand of methodologies adaptively adjusts the sample size of the MC estimates by keeping the estimation error below a measure of stationarity induced from the TR radius. In this work we explore stratified adaptive sampling strategies to equip the TR framework with accurate estimates of the objective function, thus optimizing the required number of MC samples to reach a given {\epsilon}-accuracy of the solution. We prove a reduced sample complexity, confirm a superior efficiency via numerical tests and applications, and explore inexpensive implementations in high dimension. |

| Abstract: | Although rising economic inequality is linked to declining support for democracy in multiple theoretical arguments and the public discourse alike, the empirical evidence for their linkage is mixed. We identify five main theoretical approaches that link economic inequality to democratic support, which are based on, respectively, : a) performance evaluations, b) the redistributive function of democracy, c) political inequalities, d) social and psychological dysfunctions, and e) fairness and expectations. We argue that while the majority of these arguments indeed predict some negative effect of inequality on democratic support, they can also reasonably be interpreted to imply that 1) long-term trends in inequality have consequences that are distinct from those of contemporaneous observations of inequality, 2) effects of inequality may not be linear, but rather increasing in the level of inequality, and 3) the impact of changes in inequality over time may depend on the level of inequality. We test these predictions using country-level data running from 1990 to 2022. Given the inconsistency of prior evidence, and the high degree of model-dependence implied by the choice of included countries, the choice of measurements of economic inequality, and the choice of measurements of democratic support, we compare our estimates across a range of country sample and inequality measurements, and between democratic support and democratic satisfaction. We find no evidence for long-term trend effects or non-linear effects of inequality, nor do we find evidence that the effect of changes inequality are dependent on the level of inequality. We do find reasonably robust evidence for a negative within-country effect of contemporaneous levels of income inequality on democratic support. Higher average income inequality also appears correlated with lower average democratic support, but we are unable to rule out that this is a spurious effect, in particular with respect to confounding due to difference in GDP. |

| Abstract: | This paper develops a dynamic search model in which certain ``hidden attributes" are revealed only after acceptance of an offer and may trigger continued search in the following period. The model is applied to study how workers' imperfect information about pecuniary workplace benefits (such as employer-sponsored pension and health insurance plans) during job search, and the subsequent realization of these benefits on the job, affect the multidimensional compensation packages offered in equilibrium by profit-maximizing firms. I find that unobservability of benefits prior to acceptance distorts firms' incentives toward providing inefficiently low benefits, despite the fact that lower benefits induce higher worker turnover. Furthermore, when workers differ in strategic sophistication, and therefore hold different beliefs about unobservable benefits, there exist equilibria with spurious differentiation in compensation packages. In these equilibria, the wage differential is bounded from above by the benefit differential. The model demonstrates how imperfect information about workplace benefits can explain several empirical puzzles, including inefficiently low benefit provision and large between-firm dispersion in benefits. |

| Abstract: | I estimate the effect of trade on local labor market concentration and its implications for wages using employer-employee linked data and tariff shocks from Brazil’s trade liberalization. Trade increased concentration by 7%, an effect driven by firm exit and worker flows to surviving import-competing firms. Increased concentration reduced wage take-home shares—estimated at 50 cents on the dollar pre-shock—enough to offset small wage gains from reallocation, but did not meaningfully reduce wages on net. Most of the wage declines attributed to Brazil's trade liberalization resulted instead from reductions in the marginal revenue product of labor. Incorporating informality reveals substantial regional heterogeneity. |

| Abstract: | This article examines the legal responsibility imposed on livestock farmers in the Luilu territory, Lomami Province, Democratic Republic of Congo, in relation to the prevention of zoonotic diseases. Drawing on a mixed-methods approach—combining legal analysis, qualitative surveys, and participant observation—it identifies the concrete legal obligations of farmers, their lack of awareness in practice, and the persistence of informal practices. The findings highlight that the law is only partially applied on the ground, which undermines effective prevention. The study therefore underscores the necessity of strengthening responsibility through a multisectoral One Health approach, integrating human, animal, and environmental health into a unified framework. |

| Abstract: | In early March 2026, Iranian retaliation against U.S.-led military operations halted commercial shipping through the Strait of Hormuz, driving urea spot prices up 28.2% and farm diesel prices up 34.7% within three weeks. This brief assesses the profitability impact of this dual fertilizer and fuel shock on North Dakota corn, soybean, and wheat producers using updated 2026 NDSU Projected Crop Budgets and a March 2026 producer survey. The shock arrived when corn and wheat margins were already negative at −$27.60/acre and −$33.41/acre, respectively, a substantially weaker starting position than at the onset of the 2022 Russia–Ukraine conflict. Under full exposure, the combined shock adds $31.70/acre for corn, $21.18/acre for wheat, and $5.12/acre for soybeans, with current commodity price responses insufficient to offset these increases on any crop. Corn bears the largest burden through the nitrogen channel; soybeans, though largely insulated from fertilizer costs, face margin erosion through diesel. A producer survey finds that pre-purchase timing partially buffers fertilizer exposure for many operations, but fuel costs remain fully exposed regardless, and more than half of respondents reported outstanding spring fertilizer purchases. Unlike 2022–2023, when commodity prices eventually exceeded rising input costs, the 2026 Hormuz shock combines a weaker margin baseline with a commodity price response that has so far fallen well short of restoring profitability. |
