Abstract: Abstract This paper deals with the Secular Stagnation in productivity growth that marks the US economy since the end of the Golden Age. I contribute to the understanding of this phenomenon proposing a theoretical and empirical analysis. On the theoretical side, I develop an agent-based, stock-flow consistent model to investigate the deep relationship between functional income distribution and productivity through the channel of innovation. Findings suggest that the continuous shift of income from wages to profits may have resulted in a smaller incentive to invest on R&D, with the corresponding decline in productivity growth that characterizes US Secular Stagnation. In this respect, a social compromise between workers and capitalists in terms of higher wages helps foster innovation and economic growth, but it does not necessarily entail significant improvements in terms of income concentration, because of higher unemployment rates. Additionally, I question the neoclassical belief on the negative interest-elasticity of investments, since decreases in the rate of interest are not associated with increases in capital accumulation, but they decrease income inequality through higher employment rates. On the empirical side, this paper presents a panel cointegration analysis on US manufacturing industries for the period 1958–2011. If, on the one hand, the linkage between R&D and wages is corroborated, on the other hand, I find the lack of any long-run relationship between innovative search and the rate of interest, which does not necessarily conflict with theoretical predictions.
