We study the properties of a test that determines whether two time series comove. The test computes a simple nonparametric statistic for “concordance,” which describes the proportion of time that the cycles of two series spend in the same phase. We establish the size and power properties of...

The transitional recession in countries of Eastern Europe and the Former Soviet Union has lasted much longer than expected. The legacy of the past and recent policy mistakes have both contributed to the slow progress. As structural reforms and gradual institution building have taken hold, the...

This paper provides new empirical evidence on the degree of nominal wage flexibility in a sample of nineteen industrial countries. Across countries, aggregate uncertainty increases the degree of wage flexibility in the face of various shocks. Wage flexibility stabilizes fluctuations in real...

Information on seasonal frequencies can provide valuable insights for understanding economic fluctuations. This is particularly true for Italy, where the variability of production in manufacturing is extremely high and almost entirely due to seasonal factors. This paper discusses the option of...

This paper constructs new business cycle indices for Argentina, Brazil, Chile, and Mexico based on common dynamic factors extracted from a comprehensive set of sectoral output, external data, and fiscal and financial variables spanning over a century. The constructed indices are used to derive a...

This paper reviews the ""Austrian"" theory of the business cycle first proposed by Friedrich Hayek in the 1920s. His theory claimed that credit creation by monetary authorities would push investment beyond society''s long-term willingness to save, creating a mismatch between supply and demand...

This paper examines the link between lending booms, asset price cycles, and financial crises across East Asian countries. Both theoretical arguments and empirical evidence support a strong relationship between bank lending and asset price inflation, especially in the real estate market. While...

Assessing the magnitude of the output gap is critical to achieving an optimal policy mix. Unfortunately, the gap is an unobservable variable, which, in practice, has been estimated in a variety of ways, depending on the preferences of the modeler. This model selection problem leads to a...

Real GDP growth and real effective exchange rate (REER) appreciation appear cointegrated with the current and financial accounts of the U.S. balance of payments. On this basis, we estimate reduced form equations showing that expected changes and shocks to real GDP, the REER, energy prices, and...

This paper uses a general equilibrium model to examine the central role played by commercial banks in intermediating and amplifying the capital flow shocks to the local economy in the 1997 Asia financial crisis. It finds that a sudden stop of capital inflows affects the equilibrium credit supply...
