The econometric techniques developed by Engle and Hendry (1993) are us
ed to examine empirically the exogeneity status of the real export gro
wth variable in a commonly used output growth equation. Data from Taiw
an shows that, while the weak exogeneity assumption appears to be vali
d, the super exogeneity assumption is rejected. Thus, the results cast
doubt on policy recommendations based on the export-led growth hypoth
esis.
