Abstract:
This study empirically examines the long-run relationship between growth in GDP and growth in export
in an attempt to verify the balance of payment constrained growth model or the Thirlwall’s law in the
case of an emerging economy in Sub-Sahara Africa; Ghana1. This study for the first time employs both
the Johansen test for co-integration as well as the Autoregressive distributed lag model (ARDL) (the
Bounds test), in its attempt at verifying this long run relationship. Existing studies show that these two
statistical methods provide an ideal platform in testing for the presence of Thirlwall’s law, and have been
used independently. However, whether the two methods could arrive at similar conclusion in a single test
is yet to be explored. This study explores this likelihood in addition to verifying the presence of
Thirlwall’s law in the sub-region. Data used in this study span the period 1965 to 2004. Result from the
Johansen’s approach to co-integration shows that Ghana’s GDP growth and growth in exports are
cointegrated; which supports Thirlwall’s law or a balance of payment constrained growth economy. The
outcome in the case of the autoregressive distributed lag model test for co-integration was however
inconclusive.
