A study on the relationship among inputs for agricultural production in the Mekong Delta

The study aims to analyze the possibility of replacing inputs in agricultural production in the Mekong Delta. The study analyzes data from the Household Living Standards Survey in 2018 with the use of the Cobb-Douglas production function and the Constant Elasticity of Substitution (CES) production function. The study finds out that for rice, there is a substitution relationship among three pairs of inputs; for annuals, perennials and fruit trees, they have same substitution relationship between the two pairs of inputs.
