Weblabor and capital income. With this modiﬁcation, we show that the economy exhibits saddle-path stability, regardless of whether tax revenues are returned to households as lump-sum transfers. Moreover, equilibrium uniqueness continues to hold when the source of government revenue is a constant tax rate applied to labor or total income. WebThe stability analysis shows that the transitional dynamics of the model is represented by a two-dimensional stable saddle-path. This provides a much richer dynamics for the transition paths relative to the standard neoclassical growth model without habits (e.g., [17]) or the AK endogenous growth model with habit formation (e.g., [6]) that ...
