This paper estimates the impact of geographical proximity to upper secondary schools on graduation propensity. It uses detailed information on real travel time between students' homes and schools in Norway and on the composition of study programs at each school. We find that reduced travel time...

In a topological structure affected by geographical constraints on liking, the connectivity is weakened by constructing local stubs with small cycles, a something of randomness to bridge them is crucial for the robust network design. In this paper, we numerically investigate the effects of...
