    Análisis de eficiencia técnico productiva del sector agrícola en Colombia : el papel del riego
    (Universidad EAFIT, 2022) Vélez Colorado, Laura; Molina Guzmán, Luis Alfredo
    The agricultural sector and its technical and productive efficiency have been widely studied from different approaches; the present work is based on a linear and correlation analysis between the capital factors (which are broken down into different criteria) and the production per hectare in each Colombian municipality, initially reviewing the theoretical and literature on the subject and giving a general account of the historical development of the agricultural sector in Colombia, from colonial times to the present. Next, an empirical analysis is made between the quantity produced per municipality and the different capital factors (gravity irrigation, machinery, technical assistance, drip irrigation, manual phytosanitary, chemical fertilizer, chemical phytosanitary, agricultural amendment). In order to study the causality of these relationships, an Ordinary Least Squares methodology (since the Cobb Douglas function is not linear in terms of parameters) and stochastic frontiers are used to estimate technical inefficiency. The empirical results show that all capital factors are important for agricultural production since they were statistically significant at least at 5% and irrigation and land suitability are the most relevant; furthermore, the hypothesis that the agricultural sector in Colombia is quite inefficient was tested.
