Laffer traps and monetary policy

Patrick Pintus

Review, 2008, vol. 90, issue May, 165-174

Abstract: This article focuses on the interaction, in a stylized economy with flexible prices, of monetary and fiscal policy when both are active-active in the sense that how the policy instrument is set depends on the state of the economy. Fiscal policy finances a given stream of government expenditures through distortionary labor taxes, and it operates under a strict balanced-budget rule. If monetary policy is passive, the economy may occasionally switch, because of self-fulfilling expectations, from the neighborhood of a \\"Laffer trap\\" equilibrium to the saddle-path leading to the high-welfare steady state. In the low-welfare stationary state, output, investment, and consumption are low while the tax rate is correspondingly high. However, active monetary policy may, by following a rule such that the nominal interest rate responds positively to the state of the economy, push the economy toward the high-welfare equilibrium and rule out expectation-driven business cycles.
