Spontaneous shifts in output originating within the business sector are an important factor in aggregate fluctuations. This paper develops a simple two-component decomposition of the movement of real GNP. One component is the path that GNP would have followed in order to deliver the volume of...

Apparent mean reversion and excess volatility in stock market prices can be reconciled with the Efficient Market Hypothesis by specifying investor preferences that give rise to the demand for portfolio insurance. Therefore, several supposed macro anomalies can be shown to be consistent with a...

This paper shows that stock volatility increases during recessions and financial crises from 1834-1987. The evidence reinforces the notion that stock prices are an important business cycle indicator. Using two different statistical models for stock volatility, I show that volatility increases...

Techniques of regulated Brownian motion are used to analyze the behavior of the exchange rate when official policy reaction functions are subject to future stochastic changes. We examine exchange-rate dynamics in alternative cases where the authorities promise (i) to confine a floating rate...

In discussions about different international monetary arrangements it is often maintained that exchange rate variability has a negative influence on international trade and foreign investment. This paper addresses one specific aspect of this general issue, namely the effect of exchange rate...

The optimal-diversification model of investors' portfolio behavior can give a linear relationship between the exchange risk premium and the conditional exchange rate variance. This note surveys recent empirical work that allows for the conditional variance itself, and therefore the risk premium,...

Simple regression tests that have power against the alternatives that. asset prices and expected future asset returns are excessively volatile are developed and performed for the foreign exchange and stock markets. These tests have a number of advantages over alternative, variance hounds...

This paper reviews a variety of estimates of the demand and supply elasticities of educated labor. It finds that elasticities of substitution between more and less educated labor range fran 1.0 to 2.0 and that elasticities of the supply of students to colleges are also on the order of 1.0 to 2.0...

In October 1979 the Federal Reserve shifted from an interest rate oriented operating procedure to a reserves oriented procedure. It is argued in this paper that part of the very large increase in interest rate volatility which resulted from the policy switch may have been due to shifts in the...
