The paper considers tests for structural change in time series regression models where both regressors and residuals may exhibit long range dependence. The limiting distribution of the test statistic depends on unknown parameters and is approximated by a bootstrap procedure. The asymptotic...

In this paper we propose a new approach based on principal components analysis to test for the number of common stochastic trends driving the non-stationary series in a panel data set. This test has the advantage that it is also consistent when there is a mixture of I(0) and I(1) series, making...

Our data on investment in Central and Eastern European economies reveal that, though investment rates were typically high in the 1970s, the marginal efficiency of investment was low. Investment shares begun to decline in the 1980s, before the collapse of the communist system, but there was some...
