Economic Theory, 2004, vol. 23, issue 2, 382 pages

Abstract: The results previously obtained on the finiteness property in vertically differentiated markets, with cost functions having increasing or decreasing returns, are extended to a much larger class of cost functions with local properties in a vicinity of the zero output. Moreover, existence results are provided to prove that the demonstrated properties have cases of application. Copyright Springer-Verlag Berlin/Heidelberg 2004
