Consumers make transactions of different sizes over time. This paper shows that this fact, together with transaction costs of various assets, can help in developing a theory of liquidity. Assets with different cost structures are used to purchase different sizes of transactions. This can explain...

Meltzer (1999a) shows that real monetary base growth is a significant determinant of consumption growth in the United States, controlling for the short-term real interest rate. In this paper, I show that the same property of base money holds for total output (relative to trend or potential) in...

In this Paper, we analyse the implications of price setting restrictions for the conduct of cyclical fiscal and monetary policy. We consider an environment with monopolistic competitive firms, a shopping time technology, prices set one period in advance, and government expenditures that must be...

How should monetary and fiscal policy react to adverse financial shocks? If monetary policy is constrained by the zero lower bound on the nominal interest rate, subsidising the interest rate on loans is the optimal policy. The subsidies can mimic movements in the interest rate and can therefore...

We consider standard cash-in-advance monetary models and show that there are interest rate or money supply rules such that equilibria are unique. The existence of these single instrument rules depends on whether the economy has an infinite horizon or an arbitrarily large but finite horizon.

The origins of stagflation and the possibility of its recurrence continue to be an important concern among policymakers and in the popular press. It is common to associate the origins of the Great Stagflation of the 1970s with the two major oil price increases of 1973/74 and 1979/80. This paper...

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...

When the zero lower bound on nominal interest rates binds, monetary policy cannot provide appropriate stimulus. We show that in the standard New Keynesian model, tax policy can deliver such stimulus at no cost and in a time-consistent manner. There is no need to use inefficient policies such as...

This paper investigates whether the quantity theory of money is still alive. We demonstrate three insights. First, for countries with low inflation, the raw relationship between average inflation and the growth rate of money is tenuous at best. Second, the fit markedly improves, when correcting...

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...
