PALAVRAS-CHAVEVantagens Comparativas; Indústria de Software; Intervenção Estatal;Paul Krugman CÓDIGOS JEL O25; L86A multidimensional conspiracy around the software industry:arguments for intervention in high technology sectors ABSTRACT This paper analyses the current debate about governmental intervention in high tech industries. On one hand, there are arguments against such interventions that consider the high tech industries as a capital intensive sector; instead of technological intensity, the capital intensity determines the value added. On the other hand, we could prove that there is at least one high tech industry, which is job intensive and non capital intensive, with high value added, that generates several positive externalities (the software industry). Such externalities are important arguments to support governmental intervention in high tech industries and cast doubts on the capital's value added argument.
