concentration_GW function

concentration_GW

Is there a bandwagon effect in mobility, i.e. do mobile individuals move to locations that are the destination of many others from their origin? The functional form of this statistic assumes that there are decreasing additional returns to more others on the same mobility path. For example, the probability to choose a mobility path that already contains 20 other individuals is hardly different from a path with 25 other individuals; however, there is a substantial difference in the comparison of paths with 2 or 7 other individuals.
