Public debt, productive public spending and endogenous growth
نویسنده
چکیده
We analyze effects of public debt in a basic endogenous growth model with productive public spending. We demonstrate that a discretionary policy violates the inter-temporal government budget constraint along a balanced growth path. A balanced government budget gives a unique saddle point stable growth path. With a rule based policy, two saddle point stable balanced growth paths can occur, depending on the inter-temporal elasticity of substitution of consumption and on the primary surplus policy. Higher debt goes along with smaller long-run growth and we derive a condition such that a deficit financed increase in public spending raises the growth rate. JEL: H60, O23

متن کاملEquilibrium Indeterminacy in an Endogenous Growth Model: Debt as a Coordination Device
This paper presents a two-sector endogenous growth model where public spending {which is endogenous and productive{ may generate equilibrium indeterminacy. Under certain mild conditions, there exists a continuum of expectations-driven equilibrium paths approaching a common balanced growth path. We show that the welfare-maximizing equilibrium path is associated with a labor supply as large as po...

متن کاملPolitical Economy of Debt and Growth
We present a theory of endogenous fiscal policy and growth. Fiscal policy — debt, income tax, spending on local public goods and public investment — is determined through legislative bargaining. Economic growth depends directly on public investment, private investment in human capital and, via learning-by-doing, labor supply. The model predicts that the economy converges to a balanced growth pa...
