A growing body of evidence suggests that ongoing relationships between consumers and firms may be important for understanding price dynamics. We investigate whether the existence of such customer relationships has important consequences for the conduct of both long-run and short-run policy. Our...

In this paper, we study Ramsey-optimal fiscal and monetary policy in a mediumscale model of the U.S. business cycle. The model features a rich array of real and nominal rigidities that have been identified in the recent empirical literature as salient in explaining observed aggregate...

We study optimal fiscal and monetary policy in an environment where explicit frictions give rise to valued money, making money essential in the sense that it expands the set of feasible trades. Our main results are in stark contrast to the prescriptions of earlier flexible-price Ramsey models....

When the government issues long-term bonds, the optimal time-consistent fiscal and monetary policy is to consolidate debt in a liquidity trap by increasing taxes and by taming public spending. This prescription is at odds with large deficit-spending undertaken in the US during previous liquidity...

Optimal monetary and fiscal policy are jointly analyzed in a heterogeneous two-agents New Keynesian environment, where fiscal policy is modeled in the form of lump-sum transfers set by the government. The main result is that transfer policy does not serve as a substitute for forward guidance -...

With non-controllable auto-regressive shocks, the welfare of Ramsey optimal policy is the solution of a single Riccati equation of a linear quadratic regulator. The existing theory by Hansen and Sargent (2007) refers to an additional Sylvester equation but miss another equation for computing the...

This paper characterizes conditions under which optimal monetary and fiscal policy is time consistent in a stylized small open economy with a flexible foreign exchange rate regime. It shows that these conditions depend on the way in which leisure is assumed to enter preferences and/or on the...

This paper upholds the classical Keynesian position that a laissez-faire market economy lacks a spontaneous tendency to full employment. Focusing on the UK case, it argues that monetary policy could not prevent the economic collapse of 2008-9 or achieve full recovery from the Great Recession...

The recent financial and economic crisis has triggered bold and diverse policy responses to prevent further, sharper and prolonged adverse effects to the financial and the real sector. The measures for alleviating the cycle were a feature both of the advanced and the emerging and developing...
