The objective of this paper is to explain the reasons behind the dynamics of labor productivity (LP) growth during a process of institutional and structural change. We show-by means of a theoretical discussion and an empirical analysis, conducted on a sample of 25 European countries for the period 1995-2016-that four main channels contribute to explaining the evolution of LP. First, the speed of investment, which incorporates innovation and favors an increase of LP growth; second, the speed of Research and Development (R&D), which allows for the creation of new ideas and shows the "dynamism of a society", having positive effects on LP; third, the deregulation of labor markets and the increase of temporary employment, both of which encourage labor-intensive strategies by firms, with low value-added and low productivity gains; fourth, the direction of structural change, which can take place toward services industries affected by "Baumol's disease".
