摘要
The objective of this study was to evaluate differences in the technical efficiency of alternative milk production systems on Brazilian farms. Using a panel from 2014 to 2021 (1117 observations of 383 dairy farms) we compare the technical efficiency of more recently adopted Compost-bedded Pack Barns (CPB) with that of Semi-confinement (SC), and Unstructured confinement (UNS) systems. A stochastic frontier was estimated by a Generalized True Random Effects to assess the relationship between technical efficiency and the production systems adopted, decompose efficiency into Transient (short-term) and Persistent (long-term) components, and control for unobserved heterogeneity. We found that farms using confined systems are more efficient than those using semi-confined systems. The decomposition of the Overall Technical Efficiency in its Persistent and Transient components suggests that farmers can be more efficient when dealing with short-term shocks than when deciding which system to use. The use of more capital-intensive technologies such as CPB may provide opportunities to improve dairy farm profitability and productivity growth in Brazil.
