Abstract
In this study the hedonic price method is applied to evaluate the externalities diffused by a landscape of extraordinary beauty consisting in natural resources and historic/artistic villas on the coast of Posillipo in Naples. The construction of hedonimetric curves is proposed as an approach to assess economic value of the landscape at Posillipo. The functions related to these curves derive from a plurality of hedonic prices, linked to the panorama and to the quality of historic/artistic villas that arise on the coastal strip between via Posillipo and the sea.
