This paper estimates the distribution-led regime of the US economy for the period 1947–2019. We use a time varying parameter model, which allows for changes in the regime over time. To the best of our knowledge this is the first paper that has attempted to do this. This innovation is important, because there is no reason to expect that the regime of the US economy (or any economy for that matter) remains constant over time. On the contrary, there are significant reasons that point to changes in the regime. We find that the US economy became more profit-led in the first postwar decades until the 1970s and has become less profit-led since; it is slightly wage-led over the last fifteen years.

The paper builds on the concept of (shifting) involvements, originally proposed by Albert
Hirschman (2002 [1982]). However, unlike Hirschman, the concept is framed in class terms. A model is presented where income distribution is determined by the involvement of the two classes, capitalists and workers. Higher involvement by capitalists and lower involvement by workers tends to increase the profit share and vice versa. In turn, shifts in involvements are induced by the potential effect of a change in distribution on economic activity and past levels of distribution. On the other hand, as the profit share increases, the economy tends to become more wage led. The dynamics of the resulting model are interesting. The more the two classes prioritize the increase of their income share over economic activity, the more possible it is that the economy is unstable. Under the stable configuration, the most likely outcome is Polanyian predator-prey cycles, which can explain some interesting historical episodes during the 20th century. Finally, the paper discusses the possibility of conflict and cooperation within each of the distribution-led regimes.

The paper examines the long-run fluctuations in growth and distribution through the prism of wage-and profit-led growth. We argue that the relation between distribution of income and growth changes over time. We propose an endogenous mechanism that leads to fluctuations between wage- and profit-led periods. Our model is a linear version of Goodwin’s predator–prey model, but with a reversal of the roles for predator and prey: the growth rate acts as the predator and the distribution of income as the prey. These fluctuations need to be taken into account when someone estimates empirically the effect of a change in distribution on utilization and growth. We also examine our argument in relation to the double movement of Karl Polanyi, the Kuznets curve, and the theories of long swings proposed by Albert Hirschman and Michal Kalecki.
