Equity and fairness in the location of public facilities

We analyze the problem of fairly locating two facilities providing a public good in two spatial models: a city line and a network. Each facility is characterized not only by its location but also by its quality. We introduce new notions of envy‐freeness and fairness that can be applied to spatial settings. We show that the tax scheme adopted to finance the public good has a key role in determining the existence of a spatially fair configuration of facilities.
