Do deeper regional trade agreements enhance international technology spillovers?

We examine whether regional trade agreements (RTAs) enhance international technology spillovers using a panel of patent citation data for 114 countries/regions for the period 1991-2007. We use patent citations as a proxy for technology spillovers. The focus of this study is on whether the depth of regional integration matters for technology spillovers among member countries/regions of RTAs. The depth of integration is measured by the extent to which an RTA includes legal obligations outside the current mandate of the World Trade Organization. We find that the depth of integration actually influences technology spillovers and that a deeper integration in a broad sense has a greater impact on technology spillovers than do technology-related provisions.
