We apply the idea of using reversed time series to improve the power of Johansen tests. We suggest computationally simple variants of the trace and maximum eigenvalue statistics and establish their limit distributions. Both are shown, via simulation, to yield nontrivial power gains.

The effects on three cointegration tests are examined when the series analysed are independent integrated processes, each with a structural break. Although there are differences in detail among the tests, the results indicate in all cases that, when structural breaks are neglected in the...

The balanced growth and neoclassical stochastic growth literatures imply stationarity of certain macroeconomic 'great ratios'. Four such ratios are considered: consumption:output, investment:output, the real interest rate and real money supply growth, and evidence for ratio stationarity in the...
