| Abstract: | As populations in both developed and developing countries continue to age, ensuring access to transportation that meets the mobility needs of older adults is becoming increasingly important. This issue is particularly pressing for individuals who are unable to drive or access private vehicles. Flexible Transport Services (FTS) offer a promising alternative to private transport for older people, thanks to features such as door-to-door accessibility and operational flexibility. This paper investigates travel satisfaction, perceived barriers, and attitudes toward FTS among older adults residing in the urban context of Birmingham, United Kingdom. A mixed-methods approach is employed, beginning with an analysis of travel frequency and purpose associated with FTS use, followed by a thematic analysis aimed at capturing older people's experiences, perceptions, and overall attitudes toward this mode of transport. The analysis reveals six key themes: lack of need, service provision issues, stigma, lack of awareness, convenience, and social implications. These themes highlight both the benefits of FTS and the factors that hinder its use. A central finding is the marked difference in perception between frequent users and non-users. FTS is often viewed negatively by non-users, with three of the four identified barriers predominantly arising from this group. In contrast, frequent users express satisfaction with the service, particularly emphasising its role in meeting discretionary travel needs. This is especially true for individuals over the age of 80 and those with limited access to a car. |

| Abstract: | Under California Assembly Bill 617 (Garcia, 2017), local and state agencies are working to reduce airpollution exposure in low income communities. These communities—often referred to as AB 617 communities—are disproportionately impacted by air pollution due to their proximity to transportation corridors, industrial installations, and logistics centers. A research team at the University of California, Davis investigated the impact of truck parking related activities on air quality in California’s AB 617 communities in Kern County, including truck idling, time spent searching for parking, and parking locations in communities. Searching for parking involves trucks driving extra miles to find available parking spaces, which leads to additional fuel consumption and increased emissions of pollutants such as nitrogen oxides (NOx) and particulate matter (PM 2.5 and PM 10). Once parked, prolonged or illegal parking can exacerbate congestion, noise, and localized pollution. These combined activities heighten exposure to harmful emissions in AB 617 communities, potentially leading to health issues (e.g., asthma and cardiovascular diseases). |

| Abstract: | This paper examines the measurement of self-containment and disparities in Singapore’s neighborhoods, exploring the '15-minute city' model, which promotes proximity to urban amenities. The study investigates the influence of land use diversity and accessibility to jobs and urban amenities on mobility changes using a dynamic DID and event study model, identifying key factors contributing to self-containment. It includes a long-term analysis of mobility pattern changes across four COVID-19 phases, capturing persistent behavior shifts in the new normal. The findings show that neighborhoods with greater accessibility to retail, food establishments, and leisure facilities experienced the most significant decreases in traffic volumes during weekends and weekday evenings, a trend that persisted into the endemic era. In contrast, the job-housing ratio had a lesser impact on morning traffic volume changes. The study provides insights for planning resilient neighborhoods based on the concept of self-containment. |

| Abstract: | In a collaborative effort with private agents of the oilseed industry, we carried out a research project to determine the feasibility of framing soybean production in Uruguay into sustainable development pathway. We adopted a spatial model based on land suitability analysis to estimate potential yields and the most suitable area for cultivation. We imposed several restrictions to define the potential cropping land based on risk erosion, current and alternative soil uses, transportation and logistics costs, and crop economic margins. We built different price-yields scenarios to estimate the potential area. With all restrictions imposed, the potential soybean area would be 2.1 million hectares by 2050, on rotation with other crops and pastures with an average yield of 3.3 MT/ha. This ad-hoc approach can be extended to any crop situation or region when the objective is to define how far it is possible to expand and intensify production without compromising the environment. |

| Abstract: | This study applies insights from behavioural economics to examine the challenges surrounding the adoption of the Walking School Bus (WSB), a sustainable school transportation initiative. Using thematic analysis of interviews with schoolteachers in Ferrara, Italy, we identify three key themes influencing participation: Service Characteristics, Family Determinants, and School Context. Our analysis reveals that behavioural mechanisms—such as status quo bias and the collective action problem related to volunteer recruitment—pose significant barriers to adoption, even in the face of broad recognition of the program’s benefits. The findings suggest that addressing these behavioural obstacles requires targeted interventions aimed at mitigating cognitive biases and improving decision-making processes that currently hinder participation. This research offers empirical evidence that successful implementation depends on a nuanced understanding of the interaction between practical design features and deep-seated psychological barriers that shape family mobility choices. These insights contribute to behavioural theory and offer practical guidance for promoting sustainable transport behaviours in urban settings. |

| Abstract: | This study investigates the impact of new metro stations on the real estate market in the Paris metropolitan area, leveraging rich online platform data from SeLoger. The dataset includes detailed information on listing prices, time on market, user engagement metrics (clicks and contact forms), and transaction data from DV3F. The analysis focuses on recent metro line extensions, with a methodology combining matching techniques and the Callaway and Sant’Anna (2021) estimator to identify causal effects across staggered opening timelines. Results highlight a temporary increase in property prices and a significant reduction in time on market following station openings, reflecting greater market efficiency. These changes are accompanied by shifts in online user behavior, such as fewer clicks per listing due to faster transaction cycles. By integrating digital platform data into real estate research, this paper offers novel insights into how urban infrastructure developments influence market dynamics. Future extensions will assess the anticipated effects of upcoming Grand Paris Express stations, providing a comprehensive framework for evaluating the interplay between urban mobility and real estate markets. |

| Abstract: | This article presents an analytical account of the capacity limits and operational challenges of the main airports in the S\~ao Paulo Macrometropolis. Drawing on international examples, such as London Heathrow, it discusses how large hubs combine high traffic generation with severe physical constraints, highlighting how saturation intensifies delays, operating costs, and pressures for expansion. It analyzes capacity scarcity as a central economic problem, in which runways, aprons, boarding gates, and terminals become critical resources whose use requires administrative and market mechanisms, including slot coordination, prioritization rules, and regulatory incentives. It discusses the limitations imposed by high earthmoving costs, environmental impacts, and expropriation costs, which restrict the physical expansion of central airports such as Congonhas and increase dependence on efficiency gains. Demand projections indicate that the combined capacity of Congonhas, Guarulhos, and Viracopos is likely to be exceeded, even in conservative scenarios, reinforcing the urgency of integrated planning. The effects of regulatory restrictions on Congonhas, the challenges of expanding Guarulhos, and the structural difficulties of Viracopos are evaluated, highlighting the strategic relevance of this multi-airport system for sustaining national connectivity. |

| Abstract: | This study examines how congestion pricing shapes housing market outcomes and spatial equity in New York City. Using high-frequency sales and rental data and a combination of propensity score matching difference-in-differences, geographic regression discontinuity, and event study designs, the analysis identifies distinct short-run adjustment patterns triggered by the policy announcement. Housing prices inside the toll zone fell by about 3.3% and rents by 3%, with the sharpest declines occurring immediately after the announcement. These effects weakened over time, and price resilience emerged among premium properties, indicating early market sorting and growing segmentation. The Geo-RDD results show a clear boundary penalty, with properties just inside the cordon experiencing more pronounced declines than otherwise similar properties just outside. Renters and lower-value segments were more exposed to early adjustment pressures, while implementation-stage effects were limited. The findings suggest that congestion pricing can reshape urban space not only by altering mobility incentives but also by redistributing access and opportunity. Equity-oriented design that includes early-stage support for boundary neighborhoods and renters, along with reinvestment of revenues into untolled transit access, is important for ensuring that the benefits of congestion pricing are shared rather than concentrated. |

| Abstract: | Existing literature suggests that homeowners are relatively less mobile across geographic locations and experience longer periods of unemployment compared to renters. This paper investigates the relationship between homeownership and commuting time to work. We first develop a theoretical model to demonstrate that higher housing prices lead to extended commutes to work for homeowners due to “drive-’til-you-qualify for mortgages”. Utilizing data from the Panel Study of Income Dynamics (PSID), we provide evidence indicating that homeowners, on average, spend 6.9 percent more time commuting compared to renters, after controlling for observables. Our results remain robust after considering endogeneity issues, unobservable household characteristics, and functional misspecifications. In addition, we also find that the effect is more pronounced among households residing in metropolitan areas, minority households, and those with lower income and wealth. Subsidizing homeownership in the U.S. is often justified by its presumed economic and social benefits. However, this paper sheds light on a potential negative externality of homeownership: longer commutes to work. |

| Abstract: | Aviation impacts the climate in several ways. In addition to carbon dioxide (CO2) emissions from the combustion of jet fuel, there are also the climate impacts of nitrogen oxides, particles, water vapor, and condensation trails, or contrails, white cloudlike streaks sometimes visible in the sky. Out of the non-CO2 effects, contrails are the most important, and in terms of climate impacts, they are broadly comparable to the carbon dioxide emissions from aviation.How are contrails formed? How do they affect the climate? And what can be done to reduce them? In this paper, we try to answer these questions. |

| Abstract: | After the ECOWAS-backed abolition of Nigeria’s premium-motor-spirit (PMS) subsidy in June 2023, the pump-price gap between Nigeria and Niger widened overnight from 0.23 to 0.71 USD litre⁻¹. Using a difference-in-differences design that exploits (i) 400+ border checkpoints (Clingendael 2022 GIS), (ii) 13 241 ACLED road-block events 2020-24, and (iii) monthly NBS price panels 2010-24, we show that jihadist taxation revenue on the Magaria–Jibia corridor increased by 0.9–1.4 USD million per month (≈ 18 % of IS-Sahel’s estimated budget). A structural gravity model calibrated to OECD-SWAC trade elasticities implies that a 0.10 USD litre⁻¹ price gap raises the probability of an Islamist checkpoint by 6.3% (SE 1.7, p |
