Canonical correlation statistics for testing the cointegration rank in a reversed order

Breitung, Jörg - 1998

In this paper a Canonical Correlation Analysis (CCA) is used to test the hypothesis r = r0 against the alternative r … to construct a confidence set for the cointegration rank. As the latter test, our tests are based on the eigenvalues of a … to Johansen's LR tests for determining the cointegration rank. …

Unemployment and input prices : a fractional cointegration approach

Caporale, Guglielmo Maria; Gil-Alaña, Luis A. - 2000

following the classical approach based on I(0) stationarity or I(1) cointegrating relationships, we use fractional integration/cointegration … three variables are I(1). But we only find cointegration in the presence of autocorrelated disturbances, which means that … opposed to classical cointegration, which implies long memory and slow reversion to equilibrium. This suggests that an …

Fractional integration and the dynamics of UK unemployment

Gil-Alaña, Luis A.; Henry, S. G. B. - 2000

This article is concerned with the dynamic behaviour of UK unemployment. However, instead of using traditional approaches based on I(0) stationary or I(1) (integrated and/or cointegrated) models, we use the fractional integration framework. In doing so, we allow for a more careful study of the...

A fractionally integrated model with a mean shift for the US and the UK real oil prices

Gil-Alaña, Luis A. - 2000

In this article we model the log of the U.S. and the U.K. real oil prices in terms of fractionally integrated processes with a mean shift. We use different versions of the tests of Robinson (1994), which have standard null and local limit distributions. The results indicate that if we model the...

Nonlinear error correction and the efficient market hypothesis : the case of German dual-class shares

Breitung, Jörg; Wulff, Christian - 1999

The efficient market hypothesis implies that asset prices cannot be cointegrated. On the other hand, arbitrage processes prevent prices of fundamentally related assets from drifting far away. An attractive model that reconciles these two conflicting facts is the nonlinear error correction...

Manipulation in political stock markets : preconditions and evidence

Hansen, Jan; Schmidt, Carsten; Strobel, Martin - 2001

Political stock markets (PSM) are sometimes seen as substitutes for opinion polls. On the bases of a behavioral model, specific preconditions were drawn out under which manipulation in PSM can weaken this argument. Evidence for manipulation is reported from the data of two separate PSM during...

Ergodic fluctuations in a stock market model with interacting agents : the mean field case

Horst, Ulrich - 1999

We consider a financial market model with interacting agents and study the long run behaviour of both aggregate behaviour and equilibrium prices. Investors are heterogeneous in their price expectations and they get stochastic signals about the "mood" of the market described by the empirical...
