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.Artigo Científico Private ownership of water and wastewater systems: Assessing health impacts(2025) Chaves, Rodrigo França; ADRIANO BORGES FERREIRA DA COSTAThis study examines the impact of private ownership of water and wastewater systems on disease reduction linked to sanitation in Brazil from 1998 to 2021. It updates Saiani and de Azevedo (2018), which analyzed the period 1995–2008, by incorporating over a decade of additional data, key policy changes such as the 2020 Sanitation Law, and employing the Callaway–Sant’Anna Staggered DID methodology to address heterogeneity in treatment effects. Our findings reveal mixed results: while some municipalities achieved reductions in morbidity rates, others showed no change or increases, underscoring the context-dependent nature of privatization outcomes. A notable example is the case of Tocantins, where transitioning from a hybrid private-state model to full private ownership led to a significant decrease in disease morbidity, particularly among the most affected age groups. These advancements provide a robust, updated perspective on the privatization debate, offering valuable implications for policy and practice.
