Jianjun Miao, Boston University. "Fiscal and Monetary Policy Interactions in a Model with Low Interest Rates"
Department seminar. Jianjun Miao is Professor of Economics at Boston University. He will present the paper: "Fiscal and Monetary Policy Interactions in a Model with Low Interest Rates".
We provide a dynamic new Keynesian model in which entrepreneurs face uninsurable idiosyncratic investment risk and credit constraints. Government bonds provide liquidity service and raise net worth. Multiple steady states with positive values of public debt can be supported for a given permanent deficit-to-output ratio. The steady-state interest rates are less than economic growth and public debt contains a bubble component. We analyze the determinacy regions of policy parameter space and find that a large set of monetary and fiscal policy parameters can achieve debt and inflation stability given persistent fiscal deficits.
