This paper studies the endogenous determination of telephone local calling areas. In many telephone systems, calls between users in the same calling area are local; calls to outside the calling area are long distance and priced differently. We allow the extension of this area to be treated as a strategic variable. We show the extension of the calling areas which maximises the carrier's profit to be the same which a welfare maximising regulator would choose. Under a price cap regime in which

We end the paper by considering the case of a competitive market. In this case, again, the owner of the local loop extends the local calling areas in response to decreased efficiency or increased competition of its competitors. J.E.L. Classification: L96, L51.
