It is well known that if X(t) is a nonstationary process and Y(t) is a linear function of X(t), then cointegration of Y(t) implies cointegration of X(t). We want to find an analogous result for common trends if X(t) is generated by a finite order VAR. We first show that Y(t) has an infinite...

Empirical evidence on the expectations hypothesis of the term structure is in-conclusive and its validity widely debated. Using a cointegrated VAR model of US treasury yields, this paper extends a common approach to test the theory. If, as we find, spreads between two yields are non-stationary,...

In this paper we rely on techniques recently developed by Bai and Ng (2004a) to estimate common euro-area stationary and non-stationary factors using a large-scale dynamic factor model. We find that euro-area economies share four non-stationary factors or trends and one stationary factor. By...

A dynamic relationship between foreign aid and domestic fiscal variables in Uganda is analysed using a cointegrated vector autoregressive model over the period 1972-2008. Results show that aid is a significant element of long-run fiscal equilibrium, is associated with increased tax effort and...

We estimate a so called common trends model of federal taxes and spending in the U.S.. Using dates on presidential terms as well as the NBER business cycle, we are able to interpret the estimated permanent shock as being of structural policy origin and the transitory shock as being of (to...

Recent theoretical research suggest that monetary shocks might play an important role in explaining movements in the real exchange rate in the short and medium run. Empirically, the contribution of transitory (monetary) disturbances in explaining the variance decomposition of real exchange rates...
