Estimating the bias in technical change: A nonparametric approach

In this note we propose a nonparametric methodology to estimate the bias in technical change. We apply the model to estimate the direction of technical progress for a sample of 81 countries covering the period 1970-2014. Our results confirm previous findings that during the 1980s technical change in industrialized countries has become increasingly capital-using. Moreover, we find that patterns in the bias of technical change have converged among different country groups after the productive decade 1995-2004. (C) 2017 Elsevier B.V. All rights reserved.
