We construct a utility-based model of fluctuations, with nominal rigidities and unemployment, and draw its implications for the unemployment-inflation tradeoff and for the conduct of monetary policy.<br><br>We proceed in two steps. We first leave nominal rigidities aside. We show that, under a standard...

We present a model embodying moderate amounts of nominal rigidities which accounts for the observed inertia in inflation and persistence in output. The key features of our model are those that prevent a sharp rise in marginal costs after an expansionary shock to monetary policy. Of these...

This paper discusses how optimal monetary policy is affected by differences in the combination of shocks an economy experiences and the rigidities it exhibits. Without both nominal rigidities and economic shocks, monetary policy would be irrelevant. Recognizing this, policymakers increasingly...

We study equilibria in a heterogeneous-agent incomplete-market economy with nominal government debt and flexible prices. Unlike in representative agent economies, steady-state equilibria exist when the government runs persistent deficits, provided that the level of deficits is not too large. In...

In models with complete markets, targeting core inflation enables monetary policy to maximize welfare by replicating the flexible price equilibrium. In this paper, we develop a two-sector two-good closed economy new Keynesian model to study the optimal choice of price index in markets with...

This paper characterizes the properties of various interest-rate rules in a basic forward-looking model. We compare simple Taylor rules and rules that respond to price-level fluctuations (called Wicksellian rules). We argue that by introducing an appropriate amount of history dependence in...

This paper examines what strategies policymakers have used to both reduce and control inflation. It first outlines why a consensus has emerged that inflation needs to be controlled. Then it examines four basic strategies: exchange rate pegging, monetary targeting, inflation targeting, and the...

We construct recursive solutions for, and study the properties of the dynamic equilibrium of an economy with three types of agents: (i) house- hold/investors who supply labor with a finite elasticity, consume a large variety of goods that are not perfect substitutes and trade government bonds;...

This paper considers the problem of optimal long run monetary policy. It shows that optimal inflation policy involves trading off two quite different considerations. First, increases in the rate of inflation tax the holding of many balances, leading to a deadweight loss as excessive resources...

Countries have increased significantly their public-sector borrowing since the Global Financial Crisis. In this context, we document several potential fiscal dominance effects during 2000-2017 under Inflation Targeting (IT), and non-IT regimes. Higher ratios of public debt-to-GDP are associated...
