We study the determination of Irish inflation between 1926 and 2012. The difference between unemployment and the NAIRU is a significant determinant of inflation in a simple backward-looking Phillips Curve that incorporates import prices. While there is a break in 1979-80, when the link to...

This paper uses a New Keynesian framework to study the coordination of fiscal and monetary policies, in response to an inflation shock when the policymaker acts with commitment. We first show that, in the simplest New Keynesian model, fiscal policy plays no part in the optimal policy response,...

This paper studies a simple New-Keynesian model of fiscal and monetary policy coordination when the policymaker acts under commitment. With a New Keynesian Phillips curve it is optimal to control inflation only through the use of monetary policy. But, when price-setters use a Steinsson (2003)...

Can banks maintain their advantage as liquidity providers when they are heavily exposed to a financial crisis? The standard argument - that banks can - hinges on deposit inflows that are seeking a safe haven and provide banks with a natural hedge to fund drawn credit lines and other commitments....

Financial systems are inherently fragile because of the very function which makes them valuable: liquidity transformation. Thus regulatory reforms, as urgent and desirable as they are, will definitely strengthen the financial system and decrease the risk of liquidity crises, but they will never...

We introduce mild increasing returns to scale into a version of the Real Business Cycle model. These increasing returns to scale occur as a consequence of sector-specific externalities, that is, externalities where the output of the consumption and investment sectors have external effects on the...

The paper presents the text of a lecture given at the Bank of England in December 2005 as the first in a series of lectures in memory of John Flemming. It provides a personal view of what the profession has learnt about currency unions as a result of the establishment and operation of the...

This paper has two aims. First, it provides simple theoretical models that highlight two channels whereby monetary shocks have permanent real effects and the interactions between these channels. Second, it presents an empirical dynamic model, covering a panel of EU countries, and derives the...

Two well-known, but seemingly contradictory, features of exchange rates are that they are close to a random walk while at the same time exchange rate changes are predictable by interest rate differentials. In this paper we investigate whether these two features of the data may in fact be...

Governments through the ages have appropriated real resources through the monopoly of the ‘coinage’. In modern fiat money economies, the monopoly of the issue of legal tender is generally assigned to an agency of the state, the Central Bank, which may have varying degrees of operational and...
