Currency diversification and export competitiveness: A model of the ‘Dutch disease’ in Egypt

The paper presents a dynamic portfolio model under currency inconvertibility which rationalizes the recent Egyptian experience of real exchange rate appreciation and currency diversification following the increase in oil exports and the partial financial liberalization that took place after 1976. The two shocks are linked because the relative price of manufacturing exports in terms of oil is also the premium of the ‘gray’ market rate over the official exchange rate. The effects of various official exchange rate policies on the temporary equilibrium values of the premium and the real wage and on the steady-state values of asset stocks are examined. A review of the Egyptian experience in light of the model results suggests that the unification of 1979 was ineffective against this variant of the ‘Dutch disease’ but that the restoration in 1981 of a parallel rate closer to the ‘gray’ market rate applicable to competitive exports may be more effective.
