This paper is an econometric investigation of the determinants of the real value of the South African rand over the period 1984-2006. The results show a relatively good fit. As so often with exchange rate equations, there is substantial weight on the lagged exchange rate, which can be attributed...

Fixed and flexible exchange rates each have advantages, and a country has the right to choose the regime suited to its circumstances. Nevertheless, several arguments support the view that the de facto dollar peg may now have outlived its usefulness for China. (1) China's economy is on the...

The paper reviews an event of 30 years ago from the perspective of today: a successful G-5 initiative to reverse what had been an overvalued dollar. The "Plaza Accord" is best viewed not as the precise product of the meeting on September 22, 1985, but as shorthand for a historic change in US...

The U.S. has significant interests involved in the world debt problem. It affects the profitability and even the stability of our banking system, but the debt problem also matters because debt service requires trade surpluses for debt- ors. Debtor countries have made their goods extra...

In the past fifteen years key exchange rates have moved in larger and more persistent ways than advocates of flexible rates in the late 1960s would have left anyone free to imagine. Certainly there was no expectation of constancy for nominal exchange rates. But real exchange rate movements of 30...

The appreciation of the U.S. dollar over the past five years opens important areas of research. The fact of a large and persistent real appreciation poses a challenge for equilibrium theorists to uncover the change in fundamentals and seems to support the role of long-term wage contracts in...

The essay is an extended version of the Frank D. Graham Lecture presented at Princeton University in May 1985. It discusses the interaction of inflation and exchange rate policy in a variety of contexts. Four different settings are used to highlight that role: the experiments with exchange rate...

The special role of money in the hyper inflation process, and particularly in the stabilization phase, has now been reconsidered in a bestselling essay by Sargent. The message is that credible fiscal stabilizationis the sine qua non of stopping inflation. This is definitely not viewed as being...

The exchange rate consistent with high employment and a balanced current account are rarely the same as the rates consistent with asset market equilibrium at interest rates policy makers wish to prevail. Whenever rates are freely determined the assets markets prevail and the results may be hard...

The paper is a survey of PPP theory and evidence prepared for the New Palgrave dictionary of economics. Following a statement of the absolute and relative versions of the theory, there is a brief sketch of the history of thought with emphasis on Cassel and the monetary approach. A theoretical...
