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,...

An iconic model with high leverage and overvalued collateral assets is used to illustrate the amplification mechanism driving asset prices to ‘overshoot’ equilibrium when an asset bubble bursts - threatening widespread insolvency and what Richard Koo calls a ‘balance sheet recession’....

The promising prospect of a ‘New Economy’ in the US attracted substantial equity inflows in the late 1990s, helping to finance the country’s burgeoning current account deficit. After peaking in 2000, however, US stocks fell by some 8 trillion dollars in value. To assess the welfare effects...

Using Krugman's (1991) target zone model, we find an explicit, sub-game perfect solution for a central bank wishing to stabilize the exchange rate given proportional costs of intervention. We demonstrate, however, that precommitment to narrower bands would yield a welfare gain - which provides a...

Recent empirical research by Mark Taylor and co-authors has found evidence of hybrid dynamics for real exchange rates. While there is a random walk near equilibrium, for real exchange rates some distance from equilibrium there is mean-reversion which increases with the degree of misalignment. An...

The stylised facts of currency crises in emerging markets include output contraction coming hard on the heels of devaluation, with a prominent role for the adverse balance-sheet effects of liability dollarisation. In the light of the South East Asian experience, we propose an eclectic blend of...

The Argentine convertibility regime, where the peso was fixed at parity with the US dollar, ended with a ‘twin crisis’ – a tripling in the price of a dollar and a protracted closure of the entire banking system – accompanied by an economic contraction so severe that it is often referred...

Two key issues are examined in an integrated framework: the emergence of global imbalances and the precautionary motive for accumulating reserves. Standard models of general equilibrium would predict modest current account surpluses in the emerging markets if they face higher risk than the US...

What role did the US courts play in the Argentine debt swap of 2005? What are the implications for the future of creditor rights in sovereign bond markets? The judge in the Argentine case has, it appears, deftly exploited creditor heterogeneity – between holdouts seeking capital gains and...
