Standard unit root tests and cointegration tests are sensitive to atypical events such as outliers and structural breaks. This paper uses outlier robust estimation techniques to reduce the impact of these events on cointegration analysis. As a byproduct of computing the robust estimator, we...

Long-run purchasing power is tested on 16 OECD countries using data from 1960 to 1994; PPP is rejected for some countries (Canada, Japan, Switzerland, Austria, Italy and Spain) and not rejected for others (Sweden, France, Holland and the United Kingdom). For the latter countries, impulse response...

The main purpose of this paper is to discern the dynamic causal relationships (in the Granger (temporal) sense) among sales, advertising and prices in the context of the Portuguese car market. The present research (based on multiple cointegration tests preceded by various unit root or...

The main purpose of this paper is to investigate the West-German consumption process depending on wealth and income with seasonal cointegration techniques using the framework of vector autoregressive models to capture the seasonal pattern of the series. The vector autoregressive models are the...

Using the Johansen cointegration technique, we find empirical evidence of long run co-movements between five national stock market indexes and measures of aggregate real activity including the real oil price, real consumption, real money, and real output. Real returns on these indexes are...

This paper reexamines evidence on M2 demand cointegration in the postwar United States. Equilibrium relations between M2 and various sets of its determinants are analyzed using quarterly observations from 1959:1 to 1988:4, 1990:4, and 1993:4 based on three different testing methods. For earlier...

This paper examines the long-run validity of purchasing power parity (PPP) for four high-inflation countries. The method of Zivot and Andrews (1992) is employed to detect the time-series behavior of the exchange rates and consumer price indices of these countries. We find that these variables...

This paper extends earlier work on the RID to patents relationship (Pakes-Griliches 1980, and Hausman, Hall, and Griliches,1984) to a larger but shorter panel of firms. The focus of the paper is on solving a number of econometric problems associated with the discreteness of the dependent...

This paper extends earlier work on the R&D to patents relationship (Pakes-Griliches 1980, and Hausman, Hall, and Griliches, 1984) to a larger but shorter panel of firms. Using both non-linear least squares and Poisson type models to treat the problem of discreteness in the dependent variable the...

A number of recent studies have attempted to test propositions concerning "long runt" economic relationships by means of frequency-domain time series techniques that concentrate attention on low frequency co-movements of variables.The present paper emphasizes that many of these propositions...
