The paper establishes that sovereigns, like banks, need a lender of last resort (LoLR). In the euro area the ECB, with its estimated €3.4 trillion non-inflationary loss absorption capacity, is the only credible sovereign LoLR. The ECB/Eurosystem has been acting as sovereign LoLR through its...

Commitment in monetary policy leads to equilibria that are superior to those from optimal discretionary policies. A number of interest rate reaction functions and instrument rules have been proposed to implement or approximate commitment policy. We assess these optimal reaction functions and...

We review the recent work on interest rate setting, which emphasizes the desirability of designing policy to ensure stability under learning. Appropriately designed expectations-based rules can yield optimal rational expectations equilibria that are both determinate and stable under learning....

In terms of the ratio of its public debt and public deficit to GDP the United States lies in the middle of the pack of industrial countries. The period since 1980 is the only peacetime period outside the Great Depression to see a sustained increase in the debt-GDP ratio. The budgetary...

The Paper studies the design of efficient disinflation programmes in open economies using the sacrifice ratio; that is, the cumulative additional un-employment or cumulative lost output required to achieve a 1% sustained reduction in the rate of inflation, as the metric of efficiency. The ’new...

In an attempt to clean up an unruly literature, we specify the necessary and sufficient conditions for household optimality in a model where money is the only financial asset and provide the relevant proofs. We use our results to analyse when deflationary bubbles can and cannot exist. Our...

Several recent studies imply that the response of national saving to fiscal policy is non-monotonic. In this paper, we use two data sets to search for the circumstances in which such non-monotonic responses arise: one refers to a sample of OECD countries, as in previous studies, and one to a...

The paper considers ways of avoiding a liquidity trap and ways of getting out of one. Unless lower short nominal interest rates are associated with significantly lower interest volatility, a lower average rate of inflation, which will be associated with lower expected nominal interest rates,...

We consider "robust stability" of a rational expectations equilibrium, which we define as stability under discounted (constant gain) least-squares learning, for a range of gain parameters. We find that for operational forms of policy rules, i.e. rules that do not depend on contemporaneous values...

The Paper provides a formalization of the monetary economics folk proposition that government fiat money is an asset of the holder (the private sector) but not a liability of the issuer (the state). Money is 'net wealth' in the limited sense that, after consolidation of the intertemporal budget...
