| Abstract: | In May 2023, 20.1% of Canadians usually worked most of the time from home, down from 24.3% in May 2021 and almost three times the rate of 7.1% observed in May 2016. While this increase in work from home likely reduced commuting and greenhouse gas (GHG) emissions caused by transportation (Morissette, Deng and Messacar, 2021), it also put downward pressure on the revenues and ridership of urban public transit systems, many of which experienced deficits in recent years (Griffin, 2023). Partly as a result of telework growth, the number of passenger-trips in urban transit systems in September 2023 was 18% lower than in the same month in 2019. |

| Abstract: | We study how Elon Musk's polarizing and partisan actions have impacted Tesla vehicle sales in the United States. Using county-level, monthly data on new vehicle registrations, we leverage how changes in vehicle sales over time diverge across counties with differing shares of Democratic and Republican voters. Without the Musk partisan effect, Tesla sales between October 2022 and April 2025 would have been 67-83% higher, equivalent to 1-1.26 million more vehicles. Musk’s partisan activities also increased the sales of other automakers' electric and hybrid vehicles 17-22% because of substitution, and undermined California’s progress in meeting its zero-emissions vehicle target. |

| Abstract: | This paper studies the effects of congestion relief in a spatial general equilibrium model of Luxembourg and its cross-border commuting zone. Using traffic speed data, we apply a difference-in-differences design on Luxembourgs highways to measure congestion severity and identify choke points. We then simulate counterfactual scenarios where highway speeds are set to free-flow levels and track the resulting changes in output, welfare, and fiscal revenues. Economic output rises in Luxembourg City and Esch, while other cities lose production but gain in resident welfare. For residents of Luxembourg City, we estimate a short-run welfare loss of €1, 140 per person per year, which becomes a welfare gain of €3, 490 in the long run after population reallocation. When accounting for migration from the outside economy, the welfare effect in Luxembourg City turns negative at €8, 110 per person per year. The elimination of congestion induces a fiscal gain of €2.50 billion per year in the short run, €1.18 billion in the long run, and €7.04 billion when accounting for migration inflows. |

| Abstract: | This paper examines the causal impact of road access on child health in Sub-Saharan Africa between 1980 and 2012 by combining geolocated data on child anthropometric outcomes with spatial data on road networks. To address endogeneity, we employ an instrumental variable approach based on the inconsequential units framework, constructing hypothetical road networks that connect historical cities and active mines. Our results show that closer proximity to paved roads significantly improves child health. The main mechanisms operate through improved healthcare access and utilization, higher household wealth, early signs of structural transformation, and cropland expansion. We find no evidence that these gains are offset by adverse environmental or epidemiological effects of improved road access. Overall, the findings underscore the role of road infrastructure in fostering development across Sub-Saharan Africa. |

| Abstract: | The recursive logit (RL) model provides a flexible framework for modeling sequential decision-making in transportation and choice networks, with important applications in route choice analysis, multiple discrete choice problems, and activity-based travel demand modeling. Despite its versatility, estimation of the RL model typically relies on nested fixed-point (NFXP) algorithms that are computationally expensive and prone to numerical instability. We propose a new approach that reformulates the maximum likelihood estimation problem as an optimization problem with equilibrium constraints, where both the structural parameters and the value functions are treated as decision variables. We further show that this formulation can be equivalently transformed into a conic optimization problem with exponential cones, enabling efficient solution using modern conic solvers such as MOSEK. Experiments on synthetic and real-world datasets demonstrate that our convex reformulation achieves accuracy comparable to traditional methods while offering significant improvements in computational stability and efficiency, thereby providing a practical and scalable alternative for recursive logit model estimation. |

| Abstract: | We examine how residential and work locations affect gender differences in time-use burden among homogeneous couples. We theoretically derive gendered values of time (VOTs) by location in spatial equilibrium. We show that (i) changes in VOT according to residential and work locations are determined by shadow prices of time and budget, (ii) households residing closer to the CBD have higher VOTs, and (iii) housework division varies by location, and VOTs differ between spouses spatially. Simulations substantiate these findings. Furthermore, our stated preference experiment confirms that VOT varies with residential location, after controlling for gender and household characteristics. |

| Abstract: | The social acceptability of autonomous shuttles evokes a range of emotions among consumers, notably ambivalent emotions oscillating between technological interest and fear of the device. This study analyzes these anticipated emotions and the coping strategies consumers use to manage these conflicting feelings. Relying on a qualitative approach based on 18 semi-structured interviews with potential users of on-demand shuttle services, this research identifies consumers' anticipated emotions. The findings categorize these emotions and link them to corresponding coping strategies. This study contributes to a better understanding of emotions in a new urban mobility context and offers recommendations to improve the integration of autonomous shuttles into society. |
| Abstract: | Quelle acceptabilité sociale des navettes autonomes ? La réponse ambivalente des consommateurs Résumé : L'acceptabilité sociale des navettes autonomes soulève des émotions chez les consommateurs, notamment des émotions ambivalentes oscillant entre intérêt technologique et peur du dispositif. Ce travail propose une analyse de ces émotions anticipées et des stratégies de coping mobilisées par les consommateurs pour gérer ces émotions conflictuelles. S'appuyant sur une approche qualitative basée sur 18 entretiens semi-directifs auprès d'usagers potentiels de navettes de transport à la demande, cette recherche identifie les émotions anticipées des consommateurs. Les résultats permettent de catégoriser les émotions et de les mettre en parallèle avec les stratégies de coping. Cette étude contribue à une meilleure compréhension des émotions dans un nouveau contexte de mobilité urbaine et propose des recommandations pour améliorer l'intégration de navettes autonomes dans la société. |

| Abstract: | In France and beyond, e-commerce sparks an urban logistics crisis: vans, cargo bikes, and scattered parcels choke streets, while local shops vanish. Convenience collides with physical, social, and environmental limits, creating congestion, noise, and stress for residents. Cities face a critical situation—adaptation is urgent, or urban life risks becoming unlivable. As the author underlines, structural vulnerabilities demand immediate and decisive attention. |
