In this paper we study the role of the distribution platform as an important determinant of price of paid apps. upon the targeted distribution platform. To these purposes, we construct a hierarchical model of price formation by using an ad-hoc panel dataset consisting of top paid apps from the two major app stores, gly depend on the platform where the apps are marketed.
