How strong are the causal relationships between Islamic stock markets and conventional financial systems? Evidence from linear and nonlinear tests (2014, result): “This phenomenon is somewhat similar to the nonstationary interest rates (e.g., Rose, 1988; Rapach and Weber, 2004) and seems to depend on which sample we are dealing with.”
The Euro and Inflation Uncertainty in the European Monetary Union (2009, unknown): “a recent paper, Rapach and Weber (2004) also find that inflation is non-stationary”

Confidence Intervals for Half-Life Deviations From Purchasing Power Parity (2005, background): “the joint distribution and a careful investigation of cross sectional dependence (O’Connell (1998a)). Finally, it might be worth investigating potential aggregation biases (as in Imbs, Mumtaz, Ravn and Rey (2002)) and the reasons why some countries’ half-lives are much higher than those of other cou”
Futures Contract Rates as Monetary Policy Forecasts (2012, unknown): “Although the results could be strongly sample dependent, there is some evidence that various international nominal short- and long-term interest rates may contain a unit root in the levels of the series (e.g., Rose 1988; Rapach and Weber 2004 ).6”
