We propose methods for testing hypothesis of non-causality at various horizons, as defined in Dufour and Renault (1998, Econometrica). We study in detail the case of VAR models and we propose linear methods based on running vector autoregressions at different horizons. While the hypotheses...

This paper introduces dynamics in the R&D to innovation and innovation to productivity relationships, which have mostly … individual effects and idiosyncratic errors correlated across equations and that differ in the way innovation enters the … Community Innovation Survey. The results provide evidence of robust unidirectional causality from innovation to productivity and …

This paper proposes a framework to account for innovation similar to the usual accounting framework in production … analysis and a measure of innovativity comparable to that of total factor productivity. This innovation accounting framework is … illustrated using micro-aggregated firm data from the first Community Innovation Surveys (CIS1) for seven European countries …

We review the econometric literature on measuring the returns to R&D. The theoretical frameworks that have been used are outlined, followed by an extensive discussion of measurement and econometric issues that arise when estimating the models. We then provide a series of tables summarizing the...
