The target of this paper is to question the causes of software intellectual property rights violation. To solve this question, the author analyses how has evolved the economic literature of IPR violation showing that the traditional market variables do not fulfill the requirements to explain the IPR violation. Thus, the author proposes that it is necessary to include in the model the educational, cultural, technological, and institutional context, which has not been taken into account, in order to build a coherent exposition of the problem. Subsequently, shows econometrically that it is possible to build an alternative model to explain software piracy including the a forementioned variables. The results suggest that culture, institutions and technology matter in the development of IPR protection policy even more than traditional variables as income.
