Agricultural Efficiency Gains and Trade Liberalization in Sudan AgEcon
Siddig, Khalid H.A.; Babiker, Babiker Idris.
The traditional agriculture in Sudan occupies 60% of the total cultivated land and employs 65% of the agricultural population. Nevertheless, it is characterized by its low crop productivity, which is mainly driven by low technical efficiency, while drought and civil conflicts threaten most of its areas countrywide. Therefore, it has contributed only an average of 16% to the total agricultural GDP during the last decade. This paper addresses from an empirical point of view the sectoral and macroeconomic implications of agricultural efficiency improvement in Sudan and assesses the efficiency gains under the assumption of trade liberalization. Efficiency improvement experiments are implemented by augmenting the efficiency parameters of labor, capital, and...

Spatial price transmission: A study of sheep markets in Sudan AgEcon
Babiker, Babiker Idris; Abdalla, Abdel Gabbar M..
Recent research in low-income countries has shown that high transfer costs and marketing margins may hinder the transmission of price signals, as they may prohibit arbitrage. Oligopolistic behavior and collusion among domestic traders may retain price differences between markets at levels higher than those determined by transfer costs and hinder the full price transmission and market integration (Rapsomanikis et al., 2003). This paper investigates price movements among important sheep markets in the Sudan to explore their performance and pricing efficiency. Six geographically separated livestock wholesale markets are tested spatially, using Johansen’s cointegration test (1988) and time-series price data for the period 1990–2004. Spatial analysis of the...
