This article is a supplement to Kónya (2004) which investigates the possibility of the export-led growth and growth-driven export hypotheses by testing for Granger causality between the logarithms of real exports and real GDP in twenty-five OECD countries. In Kónya (2004) two complementary testing strategies were applied. First, depending on the time series properties of the data, causality was tested with Wald tests within finite-order vector autoregressive (VAR) models in levels and/or in firstdifferences. Then, with no need for pre-testing, a modified Wald (MWald) procedure was used in augmented level VAR systems. For brevity, the results of the unit root, cointegration and MWald tests we..
