We discuss three well known plans that were offered in the twentieth century to provide an artificial replacement for gold and key currencies as international reserves: Keynes' Bancor, the SDR and the Ecu( predecessor to the euro).The latter two of these reserve substitutes were...

Many developing countries have increased their foreign reserve stocks dramatically in recent years, often motivated by the desire for precautionary self-insurance. One of the negative consequences of large accumulations for these countries is the risk of valuation losses. In this paper we...

The discomfort a government suffers from speculation against its currency determines the strategic incentives of speculators and the scope for multiple currency-market equilibria. After describing an illustrative model in which high unemployment may cause an exchange- rate crisis with...

This paper addresses the issue of the optimal stock of international reserves in terms of a statistical model in which reserves affect both the probability of a Sudden Stop-as well as associated output costs-by reducing the balance-sheet effects of liability dollarization. Optimal reserves are...

The valuation of government debt is subject to strategic uncertainty, stemming from investors' sentiments. Pessimistic lenders, fearing default, bid down the price of debt. This leaves a government with a higher debt burden, increasing the likelihood of default and thus confirming the pessimism...
