Carlin and Soskice (2005) advocate a 3-equation model of stabilization policy to replace the conventional IS-LM-AS model. One of their new equations is a monetary reaction rule MR derived by assuming that governments have performance objectives, but are constrained by an augmented Phillips curve...

In the new Keynesian model of endogenous stabilization governments have objectives with respect to macroeconomic performance, but are constrained by an augmented Phillips curve. We develop an econometric characterization of the political-economic equilibrium using the Kalman filter to model the...

This Paper studies the role of asset-market completeness for the properties of optimal policy. A suitable framework for this purpose is the small open economy with complete international asset markets. For in this environment changes in policy represent country-specific risk diversifiable in...

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...

This paper extends the standard New Keynesian dynamic stochastic general equilibrium (DSGE) model to agents who cannot smooth consumption (i.e. spenders) and are affected by external consumption habits. Although these assumptions are not new, their joint consideration strongly affects some...

Recent work on optimal policy in sticky price models suggests that demand management through fiscal policy adds little to optimal monetary policy. We explore this consensus assignment in an economy subject to ‘deep’ habits at the level of individual goods where the counter-cyclicality of...

In the particular policy framework of a monetary union, the management of fiscal policy becomes an issue of special relevance, because the fiscal discipline imposed by the monetary agreements could limit the scope of stabilization fiscal policies, and its implications on economic growth. In this...

Does market incompleteness radically transform the properties of monetary economies? Using an analytically tractable heterogeneous agent New Keynesian (HANK) model, we show that whether incomplete markets resolve "policy paradoxes" in the representative agent New Keynesian model (RANK) depends...
