Abstract Empirical works documenting highly persistent effects of negative demand shocks (‘hysteresis’) have questioned the prevailing wisdom that potential output is exogenous to aggregate demand fluctuations. We assess whether the effects of positive demand shocks also tend to persist beyond the short run. We estimate the impact of 126 aggregate demand expansions in OECD countries between 1960 and 2015 through local projections, using a dynamic two-way fixed-effects model and a propensity score-based specification. We find that demand expansions exert positive persistent effects on GDP, participation rate and capital stock. Effects on the unemployment rate and productivity are also strong and quite persistent, but evidence regarding their permanence is mixed. The effect on the inflation rate is positive but small and imprecisely estimated, and there is no sign of accelerating inflation. Our results bear relevant implications for existing models of hysteresis and for theories of demand-led growth.

As well‐known, the canonical Neo‐Kaleckian growth model fails to reconcile actual and normal rates of utilization in equilibrium. Some recent contributions revive an old proposal for solving this problem—making the normal rate of utilization an endogenous variable that converges to the actual utilization rate—justifying it with new, micro‐founded premises. We argue that these new justifications for the convergence of normal to actual utilization do not stand closer scrutiny. First, the proposed microeconomic model relies on various restrictive assumptions, some of which are mutually inconsistent. Second, the derivation of the macroeconomic adjustment mechanism from the microeconomic analysis involves a logical leap that can be justified only by a very arbitrary assumption with little economic justification. Finally, we discuss the way in which this mechanism has been incorporated into the Neo‐Kaleckian growth model by proposers of this approach. We show that, even if one puts aside, for the sake of argument, the first two points, the existence of autonomous components of demand is sufficient to invalidate the resulting macroeconomic model.

The prevailing wisdom that aggregate demand shocks determine short-run cyclical fluctuations around a supply-determined equilibrium growth rate and an associated equilibrium unemployment rate (or NAIRU) has been called into question by various strands of literature over the last few decades. Specifically, a recently revived literature on hysteresis finds significant persistence in the effects of negative aggregate demand shocks (e.g.
