Allowing habits to be formed at the level of individual goods – deep habits - can radically alter the fiscal policy transmission mechanism as the counter-cyclicality of mark-ups this implies can result in government spending crowding-in rather than crowding-out private consumption in the short...

In this paper we consider the implications of habits for optimal monetary policy, when those habits either exist at the level of the aggregate basket of consumption goods (`superficial' habits) or at the level of individual goods (`deep' habits: see Ravn, Schmitt-Grohe, and Uribe (2006))....

This paper contributes to a recent debate about the structural and institutional conditions under which discretion may be superior to timeless perspective. We show this is unlikely when the policy maker relies on a welfare-theoretic loss function obtained as a second-order approximation of...

Recent literature has reported situations in which discretion dominates timeless perspective in the presence of elements that reduce the slope of the New Keynesian Phillips curve. Considering a model-consistent welfare metric inhibits this mechanism in the standard New Keynesian framework.
