Sciences Po, room B.001, 1 place Saint Thomas d’Aquin, 75007 Paris & Zoom* Compulsory registration Can Social Intermediaries Build the State? Taxation and Informal Governance in Lagos, Nigeria In recent years, many low-income countries have attempted to formalize and extract tax revenue from their large informal economies. Why have these efforts so often failed? In this presentation, LeBas presents her book project with Jessica Gottlieb (University of Houston), which explores how taxes-for-services exchange — the central framework used in tax policy and research — may be complicated by the presence of strong, non-state institutions. Where states are weak, these social actors often […]

Sciences Po, Salle Goguel, 27 Rue Saint Guillaume, 75007 Paris, in-person Compulsory Registration Roundtable 1: Land transformations: laws, institutional arrangements and the making of property rights – Moderated by Petra Samaha | 2:00-3:45 pm Throughout history, governments have used customs and laws to organize and codify access to land in different forms. Often, land reforms amended these laws by rearranging land access through property titles. How did land reforms affect land access and ownership rights in different contexts? Did they contribute to the commodification and financialization of land by making “property” of it? What processes and actors were involved? How have […]

Sciences Po, Room H202A, 28 rue des Saints-Pères, 75007 Paris & Zoom* Compulsory Registration Spatial inequality and attachment to society across socioeconomic groups: longitudinal evidence from Chile This study examines how residential segregation affects individuals’ attachment to society, including attitudes such as sense of national belonging and identification, social and institutional trust, adherence to social norms, and behaviors like supportive social relationships, civic engagement, and political participation. It also investigates whether the association between neighborhood conditions and attachment to society varies across socioeconomic groups. We focus on Santiago, Chile, one of the most segregated cities worldwide. We combine large-scale survey […]

Sciences Po, Salle K008, 1 Place Saint Thomas d’Aquin & Zoom* Compulsory Registration De la paranoïa et de la haine. L’instabilité du monde du crime en banlieue parisienne. (On paranoïa and hate. The instability of the criminal world). Les théories de la désorganisation sociale étudient le crime comme un raté de l’expérience, un défaut dans la trame du social. Dans le sillage du travail pionnier de William F. Whyte sur l’organisation des « slums », cette présentation documente l’organisation sociale de l’expérience criminelle au carrefour d’un milieu et d’un type de subjectivité. À partir de l’éthique du défi et du sens de la […]

Sciences Po, Salle du Conseil, 13 Rue de l’Université & Zoom* Compulsory Registration Shaping the night: How data illuminates the human experience after dark We are witnessing a new era in urban governance where real-time data streams are enabling cities to predict and optimize the dynamic patterns of urban life. However, data-driven findings are incomplete without human-centered insights to understand how people and place shape one another. Gehl’s methods and digital tools to study people’s lived experience reveal that public life at night is very different from public life during the day. Drawing from years of experience in night-time governance […]

Room K008, 1 place Saint-Thomas d’Aquin, 75007 Paris & Zoom* Compulsory Registration « Public Security, Private Interests: On Social Conflict in Contemporary Brazil » Crime, violence and urban militarisation are themes widely explored in the urban studies literature focused on large Latin American cities. With high homicide and violent crime rates, the region features prominently in discussions of public security, accelerated urbanisation and violence. A series of urban ethnographies has explored how violence is connected to the conduct of everyday life, cultural and social representation, and urban territorial governance, processes of city-making and the reproduction of social inequalities. There is little discussion, […]

Sciences Po, Salle de Conseil, 13 Rue de l’Université, 75007 Paris & Zoom* Compulsory Registration Towards a Science of Cities The recent availability of data about various aspects of cities allows us to envision a science of cities validated by empirical observations. In this talk, I will discuss and illustrate with examples three major points that constitute the pillars of such a program: data (focusing on mobile phone data), modeling (including parsimonious models, simulations, and digital twins), and links with policymakers and planners. Speaker Marc Barthelemy is a former student of the Ecole Normale Superieure of Paris (rue d’Ulm). After his thesis […]

CEE Key Themes Seminar* Mandatory Registration Sciences Po, 9 rue de la Chaise, 75007 Paris & Zoom A standard approach to understanding drug markets has been the Risks and Prices model (Reuter and Kleiman, 1986) and its dynamic version developed by Caulkins and Reuter (2011). Both versions assume drug markets move to an equilibrium because drug trafficking organizations (DTOs) can fairly be modeled as responding to competitive pressures by adopting available profit-motivated business practices. More recent empirical studies and the emergence of new market forms (e.g., new synthetic drugs, on-line sales, cryptomarkets) have increased the need for models that address when, […]

Online* Compulsory Registration Title: Presentation of the book “Concrete City: Material Flows and Urbanization in West Africa” Concrete City: Material Flows and Urbanization in West Africa delivers a theoretically informed, ethnographic exploration of the African urban world through the life of concrete. Emblematic of frenetic urban and capitalistic development, this material is pervasive, shaping contemporary urban landscapes and societies and their links to the global world. It stands and circulates at the heart of major financial investments, political forces and environmental debates. At the same time, it epitomises values of modernity and success, redefining social practices, forms of dwelling and living, and […]
