Artigo Científico Subway expansion, job accessibility improvements, and home value appreciation in four global cities: Considering both local and network effects(2022) Adriano Borges Costa; ADRIANO BORGES FERREIRA DA COSTA; Ramos, Camila; Zheng, SiqiWe explore the potential of incorporating accessibility analysis in addressing the impact of subway expansions on the real estate market. We first demonstrate that by using increases in accessibility to jobs as a continuous treatment variable, rather than adopting a binary station dummy approach, we achieve better goodness-of-fit in a quasiexperimental econometric analysis. Furthermore, accessibility measures allow the exploration of impacts beyond the local effects around new subway stations, shedding light on a network impact that has been largely overlooked to date. To increase the external validity of our findings, we apply the same analysis to the cities of Santiago (Chile), Sao Paulo (Brazil), Singapore, and Barcelona (Spain). and then explore the emergent patterns. We argue that the integration of urban economics and transportation analysis via the use of accessibility measures constitutes an innovation in the empirical approach commonly adopted in the literature. The use of such measures in causal empirical studies on transportation impacts can yield more robust and comprehensive results and capture nuanced spatial heterogeneity effects.Artigo Científico Roads, transit and spatial patterns of urbanization in São Paulo: Evidence from the second half of the twentieth century(2025) Zegras, P. Christopher; ADRIANO BORGES FERREIRA DA COSTA; Zheng, SiqiThis article presents evidence of distinct long-term impacts from road and rail infrastructures on urban outgrowth and densification in São Paulo, Brazil (1947–1997) within a Global South context. Using long-difference ordinary least squares models and an instrumental variable approach, we find that the construction of avenues and arterial roads across urbanized areas drove urban expansion and accounted for forty percent of the outgrowth during this 50-year period. In contrast, rail transit investments fostered vertical neighborhood development responsible for one-third of the increase in floor area ratio, while also promoting land use specialization by attracting commercial buildings to central areas and stimulating residential real estate development in peripheral zones. Our findings align with patterns observed in the Global North, reinforcing the broader relationship between transportation investments and urban form.
