The relationships between the economic fluctuations of the US and China, the largest developed and developing countries respectively, are very important not only to both countries but also to the world economy. This paper applies a two-country correlated unobserved components model to explore...

In this paper we examine the quality of the initial estimates of the components of both real and nominal U.S. GDP. We introduce a number of new statistics for measuring the magnitude of changes in the components from the initial estimates available one month after the end of the quarter to the...

This paper contributes to the debate about the relative importance of permanent versus transitory disturbances as sources of variation in output across the G-7 countries. We employ a multivariate unobserved components model to simultaneously decompose the real GDP for each of the G-7 countries...

Recent research suggests that unobserved components models can, under certain conditions, be estimated without imposing the common zero-correlation restriction between the permanent and transitory innovations. The impact of this restriction, however, has not previously been examined in an...
