Linear-Quadratic Approximation to Unconditionally Optimal Policy: The Distorted Steady-StateTatiana DamjanovicUniversity of St. Andrews - School of Economics and Finance Vladislav DamjanovicUniversity of Saint Andrews - School of Economics & Management Charles NolanUniversity of St. Andrews February 2008 CDMA Working Paper No. 0804 Abstract: This paper establishes that one can generally obtain a purely quadratic approximation to the unconditional expectation of social welfare when the steady-state is distorted. A specific example is provided employing a canonical New Keynesian model. Unlike in the non-distorted steady state case, the approximate loss function is not defined simply over terms in inflation and output. Furthermore, optimal steady state inflation and the nominal interest rate are positive.
