Public debt and aggregate stability with endogenous growth and a state-dependent consumption tax

We analyze a basic endogenous growth model with public debt and a state-dependent consumption tax rate. We show that the balanced budget rule guarantees that the long-run growth path of the economy is unique and saddle point stable unless the tax rate is strongly regressive. In case of a strongly regressive consumption tax rate over a certain range, multiple balanced growth paths and local indeterminacy can arise
