The exchange rate has by 1984 become as central to United States economic policy discussions as it has long been in the rest of the world. In this paper we show how the standard closed-economy macroeconomic model -- the Phillips curve augmented IS-LM analysis -- has to be modified for the United...

We examine four successful stabilizations from high inflation -- Germany in 1923,Austria in 1922, in Poland 1924-27, Italy 1947 --and the two ongoing attempted stabilization in Israel and Argentina, with the aim of identifying general lessons from those episodes. The key issues in a...

This paper analyzes the behavior of the current account and the exchange rate in the British economy during the 1970's, and discusses the outlook, as influenced by the availability of oil revenues, for exchange rate developments during the 1980's.Both trade and exchange rate behavior are...

Inflation persists at moderate rates of 15-30 percent in all the countries that successfully reduced triple digit inflations in the 1980s. Several other countries, for example Colombia, have experienced moderate inflation for prolonged periods. In this paper we first set out theories of...

Recent research based on variance ratios and multiperiod-return autocorrelations concludes that the stock market exhibits mean reversion in the sense that a return in excess of the average tends to be followed by partially offsetting returns in the opposite direction. Dividing history into...

Risk premia in the stock market are assumed to move with time varying risk. We present a model in which the variance of time excess return of a portfolio depends on a state variable generated by a first-order Markov process. A model in which the realization of the state is known to economic...

When the instrumental variable is a poor one, in the sense of being weakly correlated with the variable it proxies, the small sample distribution of the IV estimator is concentrated around a value that is inversely related to the feedback in the system and which is often further from the true...

New results on the exact small sample distribution of the instrumental variable estimator are presented by studying an important special case. The exact closed forms for the probability density and cumulative distribution functions are given. There are a number of surprising findings. The small...

This paper surveys much of modern macroeconomics. The focus is on the core macroeconomic issue, of the reasons for macroeconomic fluctuations and sometimes persistent unemployment. To provide continuity and perspective on how promising research leads of the past turned out, the paper starts by...

Between December 1994 and March 1999, Mexico, Thailand, Indonesia, Korea, Malaysia, Russia and Brazil experienced major financial crises which were associated with massive recessions and extreme movements of exchange rates. Similar crises have threatened Turkey and Argentina (2000 and 2001) and...
