We estimate the relationship between productivity and trade for a panel of countries over the period 1980 to 2000 using instrumental-variables estimation of a productivity equation. We note that some estimates of productivity gains attributed to trade capture instead the roles of institutions...

This paper offers an empirical examination of the determinants of a nation’s ability to produce commercially viable innovations, measured as patents, across a sample of twenty three advanced economies. The approach employed is based on estimating National Innovation Capacity that focuses on...

This paper evaluates the performance of alternative estimation methods for multiplicative and log models with heteroskedasticity. Contrary to Santos Silva and Tenreyro (2006), the results of a simulation study indicate that the Pseudo Poisson Maximum Likelihood estimator (PPML) is not always the...

This paper estimates the effects of the EU enlargements in the 2000s for trade in parts and components and trade in final goods separately. A gravity model is applied to disaggregated trade data over the period 1999 - 2009 for trade between EU and OECD countries. The estimation approach accounts...
