The traditional theory of commercial banking explains maturity transformation and liquidity provision assuming no asymmetric information and no excess profits. It captures the possibility of bank runs and business cycle risk; but it ignores the moral hazard problems connected with risk-taking by...

How and why do financial conditions matter for real outcomes? The ‘workhorse model of money and liquidity’ of Kiyotaki and Moore (2008) shows how--with full employment maintained by flexible prices--shifting credit constraints can affect investment and future aggregate supply. We show that,...

We formulate a stochastic, rational-expectations model of exchange rate determination, in which there are random shocks to the process of sluggish price adjustment. We examine the effects of imposing limits upon the range of variation of both nominal and real exchange rates and describe the...

In this paper the Maximum Principle is used to derive optimal policies for linear-quadratic, continuous-time economic systems where there may be more than one policy-maker and where the private sector may have rational expectations. The analogy between solving full-information differential games...

The extent which exchange rate management can coexist with an independent monetary policy is examined in the context of a model with exchange rate bands. Using a Dornbusch model in which stochastic shocks are added to the Phillips curve, we analyze the implications of assuming that the monetary...

In the first decade of its existence the EMS passed through three phases of realignments: full accommodation, partial accommodation and zero accommodation of inflation differentials. To what extent, however, does the new freedom of capital movements within the EC rule out such gradual...

We study a model of sovereign debt crisis that combines problems of creditor co-ordination and debtor moral hazard. Solving the sovereign debtor’s incentives leads to excessive ‘rollover failure’ by creditors when sovereign default occurs. We discuss how the incidence of crises might be...

Germany is generally regarded as the nominal anchor for Europe. Its participation is the sine qua non of EMU. It has been the largest net contributor to EU finances, the leading proponent of greater economic and political union, and the leading example of the virtues of fiscal and monetary...

Using a variant of the Cagan model with rational expectations, this paper shows that expected stabilization can result in a budget deficit in excess of the maximum inflation tax. A cap on the deficit dampens inflation expectations and raises real balances, thus increasing the yield of the...

Credit market imperfections have been blamed for the depth and persistence of the Great Depression in the US. Could similar mechanisms have played a role in ending the East Asian miracle? After a brief account of the nature of the recent crises, we use Kiyotaki and Moore’s (1997) model of...
