REM Working paper series, nº 0383/2025http://hdl.handle.net/10400.5/102501We model the expansion of (higher) education in an economy composed by regions that only diƯer in population density. The schooling process takes place sequentially across regions in descending order of demographic density and it implies a substitution of modern industrial technologies for traditional land-based ones. Under the crucial assumption that young people may travel to school within the region where they live, but not across regions, the model explains why both the literacy rate and per capita income increase, albeit at a decreasing rate. Furthermore, is allows us to understand why the average students’ commuting distance tends to rise despite the geographical decentralization of the educational system.engEducation SpreadPopulation DensitySpatial Monopolistic CompetitionWage Premium of EducationModern versus Traditional Technologyworking paper
