Analysing the Relationship between Budget Deficit and Current Account Deficit in Namibia

Abstract

Is there a causal relationship between budget deficit and current account deficit? This study attempts to explain the significance of the transmission mechanism, (the exchange rate and interest rate) in explaining the twin deficit hypothesis (i.e. budget deficit and current account deficit) in Namibia. The study employed analytical methods of unit roots, cointegration, Granger-causality, and the impulse response function for estimation. In contributing to this ongoing debate, the study used the case of Namibia over the period spanning from 1990-2014 using time series data. Budget deficit and current account deficit proved to be significant. There is a unidirectional causal relationship between budget deficit and current account deficit in Namibia which runs from current account deficit to budget deficit. However, the transmission mechanism proved to be less significant in explaining the twin deficit hypothesis in Namibia.  Having found a positive relationship between current account deficit and budget deficit in Namibia, the government should consider curbing the increasing current account balance as a way of reducing its adverse effect on the budget balance. From this study, it is indicated that stabilising the current account deficit problem could assist in managing the budget deficit problem in Namibia.
