The main objective of this paper is to decompose the productivity growth of Egyptian cotton production. We employ the stochastic frontier approach and decompose the changes in total factor productivity (CTFP) growth into four components: technical progress (TP), changes in scale component (CSC), changes in allocative efficiency (CAE), and changes in technical efficiency (CTE). Considering a situation of scarce statistical information, we propose four alternative empirical models, with the purpose of looking for convergence in the results. The results provide evidence that in this production system total productivity does not increase, which is mainly due to the negative average contributions of CAE and TP. Policy implications are offered in light of the results.

This study aims to measure the total factor productivity of the main governorates of wheat production in Egypt during the time period 1990-2012 and decompose it into technical change, efficiency change and scale change. We used Global Malmquist TFP index as a non-parametric approach. The results indicated that the contribution of technical change component is more important than the efficiency change component. In fact technical change rose, 25.7%, while efficiency change presented a little decline, 3.7%. The decomposition of efficiency change indicated that the main problem of wheat production in Egypt was scale efficiency that worsened by 5.5%.

Oranges and mandarins are classified as important citrus in Egypt. The study usesa stochastic frontier production function to measure the efficiency of production for oranges and mandarins in Egypt during 1997-2019. During the time period 1997-2019, the mean of oranges production is 2317.69 thousand ton, while the mean of mandarins production is 753.53 thousand ton. The minimum value of oranges production is 1441.652 thousand ton and for mandarins production is 421.811 thousand ton (1998), while the maximum value of oranges production is 3351.307 thousand ton and for mandarins production is 985.439 thousand ton (2015). In 2019, Noubaria governorate has the highest production of oranges and Mandarins, while Fayoum governorate has the lowest production of oranges, and Dakahlia governorate has the lowest production of Mandarins. The results of the study indicate that the efficiency for oranges and mandarins production make clear improving over time. The study recommends that the government should encourage and motivate farmers in different governorates to produce the most efficient crops in their governorates.

The study uses Data Envelopment Analysis (DEA) through an output-oriented model and Constant Returns to Scale (CRS) to estimate the efficiency of chickpeas production in the Egyptian main governorates during 2006-2019. During the period of the study 2006-2019, the mean of production, area, and yield is 5390.36 ton, 6027.71 feddan, and 0.91 ton/feddan, respectively. Assuit has the highest production mean and the largest area mean, while Luxor has the lowest production mean and the lowest area mean. The minimum mean value of yield is 0.72 ton/feddan at Luxor, while the maximum mean value of yield is 1.14 ton/feddan at Menia. The results of the study indicate that the mean of efficiency for chickpeas production in the main governorates is 94.5%. The minimum value of efficiency is 0.876 at governorate of Aswan, while the maximum value of efficiency is 1.000 at governorate of Assuit. The study recommends implementing the system of land consolidation to increase the efficiency of chickpeas production in Egypt.
