>>5865288>spatial agglomerationI learnt this as Hotelling's Law of Minimal Differentiation in game theory. It explains why vendors might cluster together and can also demonstrate why in political economy two parties will both attempt to adopt similar policies to capture a majority despite apparent ideological differences (ie consider the analogy of voter preferences uniformly distributed on a left-right spectrum of political opinion line, similar to shops situated along a street etc. The Nash is again located at the middle)
