In this paper we argue that the relevant decision for the majority of US households is not the fraction of assets to be held in interest-bearing form, but whether to hold such assets at all (we call this ‘the decision to adopt’ financial technology). We show that the key variable governing...

Should one think of zero nominal interest rates as an undesirable liquidity trap or as the desirable Friedman rule? I use three different frameworks to discuss this issue. First, I restate Cole and Kocherlakota's (1998) analysis of Friedman's rule: short run increases in the money stock -...

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...

Central banks can go broke and have done so, although mainly in developing countries. The conventional balance sheet of the central bank is uninformative about the financial resources it has at its disposal and about its ability to act as an effective lender of last resort and market marker of...

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...

This paper demonstrates how time consistency of the Ramsey policy (the optimal fiscal and monetary policy under commitment) can be achieved. Each government should leave its successor with a unique maturity structure for the nominal and indexed debt, such that the marginal benefit of a surprise...

This paper explores under what conditions a European Monetary Union (EMU) is an optimum currency area. The scope for an EMU increases with convergence of structural and fiscal policies, small money holdings, a conservative European Central Bank, and dependent national central banks. How national...

In contrast to the recent literature on the optimal inflation tax, we show that, in models where money reduces transactions costs, it is optimal to set the inflation tax to zero when seigniorage is replaced by revenue from distortionary taxes. The main reasons for this result are that the...

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...

We derive principles of optimal short run monetary policy in a real business cycles model, with money and with monopolistic firms that set prices one period in advance. The only distortionary policy intruments are the nominal interest rates and the money supplies. In this environment it is...
