This paper investigates whether returns to domestic R&D and international R&D spillovers should be estimated without considering the heterogeneous impact of unobserved common shocks, as has been done by the literature in this area. Using a panel of 50 economies from 1970-2011, I find that when...

This paper investigates the effects of the domestic and foreign R&D weighted by bilateral imports on productivity accounting for the heterogeneous impact of unobserved micro and macroeconomic common shocks, which are modeled in a multifactor error structure. Using a panel of 50 economies from...
