Abstract

The aim of this study is that of further exploring the knowledge spillover effects of Large International firms. In particular, we implement a spatial analysis in United States, Japan and Europe.  We use technological vectors of firms to compute Jaffe proximity measure in such a way that we get knowledge externalities relative to different countries. To our end, we estimate the spatial-autoregressive model where we consider also additional endogenous variables. The findings demonstrate the significant positive effect predicted by the core literature about this topic.
