In this lecture I document the proliferation of gross international asset and liability positions and discuss some of the consequences for individual countries’ external adjustment processes and for global financial stability. In light of the rapid growth of gross global financial flows and...

This paper analyzes current stresses in the two key areas that concerned the architects of the original Bretton Woods system: international liquidity and exchange rate management. Despite radical changes since World War II in the market context for liquidity and exchange rate concerns, they...

A key precursor of twentieth-century financial crises in emerging and advanced economies alike was the rapid buildup of leverage. Those emerging economies that avoided leverage booms during the 2000s also were most likely to avoid the worst effects of the twenty-first century’s first global...

We propose that analysis of purchasing power parity (PPP) and the law of one price (LOOP) should explicitly take into account the possibility of ‘commodity points’ – thresholds delineating a region of no central tendency among relative prices, possibly due to lack of perfect arbitrage in...

This paper surveys the performance of international capital markets and the literature on measuring international capital mobility. Three main functions of a globally integrated and efficient world capital market provide focal points for the analysis. First, asset-price arbitrage ensures that...

This paper analyses the constraints European Union law places on the 1 January 1999 choices of irrevocably fixed conversion rates between the euro and the currencies of EMU members states. Current EU legislation, notably the Maastricht Treaty, requires that the bilateral currency conversion...

Simple techniques of regulated Brownian motion are used to analyse the behaviour of the exchange rate when official policy reaction functions are subject to future stochastic changes. We examine exchange rate dynamics in cases where the authorities promise (i) to confine a floating rate within a...

This paper develops a dynamic model of seigniorage in which economies' equilibrium paths reflect the ongoing strategic interaction between an optimizing government and a rational public. The model extends existing positive models of monetary policy and inflation by explicitly incorporating the...

The recent financial crisis teaches important lessons regarding the lender-of-last resort function. Large swap lines extended in 2007-08 from the Federal Reserve to other central banks show that the classic concept of a national last-resort lender fails to address key vulnerabilities in a...

The exchange-rate regime is often seen as constrained by the monetary policy trilemma, which imposes a stark trade-off among exchange stability, monetary independence, and capital market openness. Yet the trilemma has not gone without challenge. Some (e.g., Calvo and Reinhart 2001, 2002) argue...
