This paper provides a formal test of the null hypothesis of a unit root in the log-level of labor productivity against the alternative of linear trend stationarity with a one-time structural break in the level and slope of the trend at an a priori unknown date. Using some newly developed time...

It has recently been argued that when the conventional specification of M2 income velocity is extended to include proxies for two types of institutional change, as emphasized by Bordo and Jonung (1987, 1990), corresponding to the process of monetization and increasing financial sophistication of...

This paper uses some newly developed methods and techniques to examine the dynamic properties of international output in the presence of a structural break. The author provides statistical evidence to show that the unit root test results can, in some cases, be sensitive to whether a one-time...

This paper tests the hypothesis that the time-series process of income inequality has experienced a structural break. The timing of the structural break is treated as an unknown parameter to be estimated from the data because it is not possible to associate a single episodic policy event with...

This paper expresses econometric qualms about M. D. Bordo and L. Jonung's (1981) analysis of long-run volocity. They did not recognize that, for U.S. and Canadian data, the log of velocity has a unit root. Hence, estimation of a log-level regression may produce spurious regressions. When Bordo...
