  • Evaluation of Total Factor Productivity of Sudanese Sugar Company Farms: A Non-parametric Analysis 1999-2007

This study analyzes productivity growth in Sudanese Sugar Schemes over the period 1999-2007. The application
and specification of the output-based Malmquist total factor productivity index, data variables and sources, results,
and some policy implications for the Sudanese sugar farms are discussed and presented The Malmquist productivity
index was used to measure the technical and economic or allocative efficiency. Data Envelopment Non-parametric
analysis (DEA) a model of output-oriented total factor productivity (TFP) was used in the analysis. This model
provided meaningful results regarding technological and economic behavior relationships over time, using balance
panel data on Sudanese Sugarcane Schemes. Efficiency change contributed to the total factor productivity progress
and technical change to its regress to the Sudanese Sugarcane Schemes by 0.2% and 12.5%, respectively.
The results indicated that the Sudanese Sugar Schemes had an annual average increase in TFP of 12.7%. The
regression analysis results showed that expenses were negatively and significantly related to TFP.

  • Efficiency of Selected Sudanese Cattle Markets: A Bivariate Cointegration Approach (1995-2011)

The importance of the livestock trade to the national economy of Sudan is significant; however, Sudan was
adversely affected by the global crisis through a decline in oil and other external receipts. The main objectives of
this study is to investigates price movements among important livestock markets in the Sudan to explore
their performance and pricing efficiency. The stationarity of data tested using the unit root test and then market
integration was tested using bivariate cointegration analysis. The study found strong evidence of cointegration of
pairs of markets. The error correction mechanism adjusts significantly to shocks to its equilibrium relationship. The
estimated coefficients for ECM were fluctuated between 4% and 24% and significant at 1% level, suggesting slowing
adjustment towards the long-run equilibrium. This implies that any shock that forces prices from their long-run value
would take a long time for prices to return to their equilibrium, although the speed of adjustment was highest in case
of Omdurman on Nyala and lowest in case of Nyala on Elobied, this might be due to supply and demand relation
between Nyala and Omdurman in sense that Nyala and Elobied were supply markets. The recent paved roads that
linked between the markets might accelerate and facilitated the movement between these markets, in addition to a
huge capital that allocated to livestock business recently.

  • Financial and Economic Evaluation of Cotton Production in New Halfa Agricultural Corporation, Kassala State, Sudan (1981/1982- 2009/2010)

The New Halfa agricultural Production Corporation (NHAPC) is considered as one of the leading agricultural
scheme in cotton production, being the second largest in comparison with the Gezira scheme concerning the area.
The Government’s agricultural policies were the main factors for the studying and knowing the financial and economic
evaluation indicators for the production of cotton in New Halfa Agricultural Production Corporation during the period
(1981/1982-2009/2010), and the comparison between these indicators for different periods in producing cotton
at New Halfa Agricultural Production Corporation (first period 1981/1982-1991/1992) individual account system,
(second period 1992/1993-2009/2010) liberalization in the following phases: Financial and economic indicators (net
present worth NPW, benefit cost ratio B/C , internal rate of return IRR, net benefit investment N/K ratio, and payback
period), area, production and average yield. The study was mainly based on the secondary data of the cotton crop
at (NHAPC) such as areas, production, average yield, return, costs, benefits and net benefits for period (1981/82-
2009/10), using descriptive statistics, simple mathematics, and different ways of analysis and descriptive tables. The
financial and economic evaluation during the periods (1981/1982- 2009/2010), (1981/1982-1991/1992), (1992/1993-
2009/2010) study showed that the production of cotton was feasible and the indicators were positive. The study
recommended that the Government should have a commitment to appropriate agricultural policies, subsidize the
agricultural sector particularly with regard to increasing the areas of cotton production, reduce the cost of production,
process cotton locally to increase the added value, and manufacture the inputs locally for making more foreign
currencies, and increase the cotton production through research development and extension.
