الملخص EN

The main objective of this study was the descriptive economic and econometric analysis of cost functions of olive oil in Jerash Governorate (rainfed farming).

Also, this study aimed at determining the economically efficient size and the profit-maximizing size.

Primary data, collected in 2006 through research interviews with farmers, were used.

Farms in the rainfed areas in Jerash Governorate were divided into five acreage categories.

Through the descriptive economic analysis of costs of production of olive oil, it was shown that the highest average cost of production of one dunum in Jerash Governorate was (82) JDs, and the lowest average cost of production of one dunum was (57) JDs.

From the analysis of costs and returns, the results indicated that the highest net return (profit) in Jerash Governorate was (163) JDs / dunum, and the lowest net return (profit) was (113) JDs / dunum.

Also, the results of the descriptive economic analysis indicated that the lowest average cost of production of 1 kg of oil was (0.77) JD and the highest average cost of production of 1 kg of oil was (1.26) JD.

Using the econometric models of cost functions, the economically efficient size and the profit-maximizing size were computed and determined for each category.

Category # 5 in Jerash Governorate was the best, indicating that farmers' practices were too far from these sizes based on the econometric analysis; namely the economically efficient size and the profit-maximizing size.

Also, the results indicated that the economically efficient acreage size was (98) dunums for category # 5 which was not far from the actual acreage of this category in Jerash Governorate.
