Secular stagnation : insights from a new Keynesian model with hysteresis effects

To analyse the most important aspects of the Secular Stagnation hypothesis, this paper considers the effects of hysteresis in potential output in a New-Keynesian model that is extended with endogenous potential output. To do so, a number of simulations of relevant scenarios is undertaken. It is demonstrated that extending the New-Keynesian model with hysteresis has a number of crucial implications for macro-economic adjustment and macro-economic management. It is indicated how the model can contribute to a better understanding of a number of important elements of the Secular Stagnation hypothesis.
