| Summary: | Sudan's cotton industry has assumed a key role since the mid 1920's in its
national economic development both on economic and social grounds. This study
addresses the issues of government intervention on Sudan's cotton industry. Control
measures in the cotton industry which span area determination, cotton producers'
price determination, cotton exchange rate and cotton tax rate, are believed to have
negative impacts on the cotton industry supply response. The major objective of this
study is to investigate the implications of government intervention on cotton
industry. The study employs an econometric approach to examine the behavior of
the cotton supply response. The study uses time series data over the period 1969 -
1998. The long and medium staple cotton models incorporate five equations, namely
area, yield, export supply, producers' price and export demand The model equations
have been structured to allow for a balanced representation of both price and nonprice
factors. The models have been estimated using the auto--regressive distributed
lag technique and error correction model The study employs Theil's inequality and
root mean square percentage error as validation techniques to ascertain model performance. A simulation of alternative policy scenarios with regard to cotton
exchange rate and cotton tax rate was carried out to assess the impact of policy
reforms on the magnitude of the endogenous variables. In addition, a simulation of
the policy scenario with regard to food self-sufficiency as a policy objective was also
conducted.
The findings of the study support the view that government interventions on
Sudan's cotton industry have had negative implications on the cotton supply function
components, namely, area and yield The various forms of government intervention
have had, on the whole, undermined the provision of adequate incentives to cotton
producers and as such have resulted in the lack of responsiveness on part of the
cotton producers to changes in the cotton world market. Such a situation has
deprived the country of its inherent comparative advantage as cotton producer. The
study recommends corrective policy reforms in relation to producers' price
determination mechanism and its associate variables mainly cotton exchange rate and
cotton taxation. Moreover, non-price policy variables, which are mainly of
technological nature, have to be appropriately considered in cotton production
planning process in order to elucidate positive supply response. |
