Traditional tests of conditional asset pricing models are performed under the assumption of rational expectations and presume that the use of realized returns as a proxy for expected returns is acceptable. This paper turns the tables and asks what realized returns we would observe, given the...

We investigate the role of currency risk on stock markets in two interlinked Nordic countries exhibiting a gradual move from fixed to floating exchange rates. We apply the Ding and Engle (2001) covariance stationary specification in a multivariate GARCH-M setup to test a conditional...

We study information flows in China's stock markets. By using panel data methods we test for a unit root in the price premium of domestic investors' A shares over foreign investors' B shares, as well as cointegration between the A- and B-share prices on the Shanghai and Shenzhen stock exchanges....

In this paper we study market segmentation and information flows in China’s stock markets. By using panel data methods we test for a unit root in the price premium of domestic investors' A shares over foreign investors’ B shares as well as cointegration between the prices of the A and B...

Many economic events involve initial observations that substantially deviate from long-run steady state. Initial conditions of this type have been found to impact diversely on the power of univariate unit root tests, whereas the impact on multivariate tests is largely unknown. This paper...

The article proposes a general test for the cointegrating rank in vector autoregressive models. The test is based on the eigenvalues of the companion matrix, more precisely on the sum of the real parts of those closest to one. The roots of the companion matrix are often inspected as a diagnostic...

This paper uses panel unit root and cointegration methods to test the stationarity of the premium on domestic investors’ A shares over foreign investors’ B shares and cointegration between the A and B share prices on the Chinese stock exchanges. We find that the A share price premium is...
