摘要

In developing countries, it is common that poor households slowly develop their housing, following a process of progressive improvement, a phenomenon called consolidation. The level of consolidation in urban neighborhoods can vary as a function of several factors including the street layout. If the streets in a neighborhood have a small number of directional changes (i.e., there is a higher-level street integration), it is expected higher pedestrian movements that could lead to more frequent social and economic interactions and thus to a faster consolidation. Using watersheds as an instrument for street integration, in this paper we approximate the causal effect of street integration on consolidation in the city of Medellín, Colombia. Our results suggest that higher levels of integration led to higher levels of consolidation.
