We propose a methodology for constructing operational indices of inflation pressure, the monetary authority's effort to reduce this pressure, and the degree to which inflation pressure is alleviated. We begin with model independent definitions of these concepts. When our definitions are applied...

A positive Lyapunov exponent is one practical definition of chaos. We develop a formal test for chaos in a noisy system based on the consistent standard errors of the nonparametric Lyapunov exponent estimators. For international real output series, the hypothesis of the positive Lyapunov...

A positive Lyapunov exponent is one pratical definition of chaos. We develop a formal test for chaos in a noisy system based on the sign of the Lyapunov exponent. The test utilizes nonparametric regression techniques including local quadratic regression and neural networks. When our procedures...

This analysis, using Current Population Survey data, yields statistically compelling evidence that cyclical variations in gross flows of U.S. workers—that is, variations by business cycle phase in the number of workers transitioning from one labor market state to another each month—were...

Data from Okinawa's monetary union with the United States in 1958 and with Japan in 1972 are used to obtain a quantitative indication of how monetary union might affect the behavior of nominal and real shocks across two economies. With monetary union, the variance of the real exchange rate...
