The hypotheses of sectoral incremental rates of returns gravitating around or converging towards a common value are tested on data for various OECD countries relying on an econometric method able to account for residual autocorrelation and cross-sector correlation. Our null hypotheses receive only a mixed empirical support.

Abstract
The hypotheses of sectoral incremental rates of returns gravitating around or converging towards a common value are tested on data for various OECD countries relying on an econometric method able to account for residual autocorrelation and cross-sector correlation. Our null hypotheses receive only a mixed empirical support. This is interpreted as the result of limitations to capital mobility and of persistent differentials in the innovative performance of industries.
