- Abstract
Distribution theory is one of the most important pillars in economics, The process of determining the wages and returns of the factors of production is one of the important topics in the study of production theory. The study aims to determine the returns of the elements of agricultural production in the case of field crops by applying the Euler distribution theory, where the Cobb-Douglas function was used to estimate the production function to estimate the real value of the returns of the factors of production for their contribution to the production process during the period 2015-2020. The results indicate that the independent variables included in the model explain about 98% of the total changes in the production value of field crops. The statistical significance of the various regression coefficients of the function has been proven, and the estimates reflect the constant return to scale. The value of the marginal product for the factors of agricultural production (land, human labor, capital, irrigation water), which was estimated at about 2597, -78.8, 3.3, 0.36 pounds per feddan, per man, per unit of Capital and per cubic meter of irrigation water during the agricultural season in the average winter and summer seasons and the average period 2015-2020. The estimates indicated that the statistical significance of the dummy variable that reflects the agricultural season was proven, and accordingly the rental value of feddan varied in the winter season than in the summer season as well as its difference between crops different within the same agricultural season. It also reached its maximum in garlic, then wheat, and then onions in the winter season, while for the summer season, it was maximum for the sugar cane and cotton crops. Estimates indicate that the market returns of the land at constant prices are less than its contributions to the production of the field crops under study, except for the per-feddan rent for the clover tahreesh crop with winter season, and the cotton and sesame crops with the summer season. The negative marginal productivity of the human labor input for the winter season is higher than its counterpart for the summer season, as it was estimated at about 4.7 and 3.2 pounds for field crops for the winter season and the summer season, respectively. However, it was found that the capital resource receives returns less than the real value of its contributions to the production of the field crops under study, with the exception of chickpea, clover, clover tahreesh, onions and garlic in the winter season, and cotton, sugar cane, groundnut and sesame crops in the summer season. The value of the marginal product per cubic meter of irrigation water was estimated at about 0.68 pounds in the winter season, which is higher than its counterpart in the summer season, which was estimated at 0.27 pounds. It is estimated that if the irrigation water input pays dividends, the garlic crop will achieve the highest returns. The values of the marginal products of the production elements under study varied, which indicates that the current cropping structure does not achieve economic efficiency in the use of agricultural resources. It necessitates reconsidering the price policies of different crops and the prices of the various agricultural production resources.
