In this paper, test procedures for no fractional cointegration against possible breaks in the persistence structure of a fractional cointegrating relationship are introduced. The tests proposed are based on the supremum of the Hassler and Breitung (2006) test statistic for no cointegration over...

This paper focuses on the estimation and testing of multiple breaks that occur at unknown dates in multivariate long memory time series regression models, allowing for fractional cointegration. A likelihood-ratio based approach for estimating the breaks in the parameters and in the covariance of...

There are two intriguing questions about the transition process undertaken by the Ukraine since its declaration of sovereignty in December 1991. (i) Why had one of the more prosperous republics of the former USSR in terms of economic development and population welfare been suffering of both a...

This paper makes three contributions: First, I construct annual time series of gross domestic investment and national saving in the U.S. for the 1897–1949 period using historical component series. I compare the qualitative and quantitative properties of the newly constructed series with the...

This paper tests the stability of the U.S. federal intertemporal budget constraint over the postwar period. The implied equilibrium budget path is estimated and used to determine which component of the budget has greater responsibility for the recent intertemporal violations.
