Resumen
Descripción
Agricultural production in greenhouses is an important user of energy and can lead to greenhouse gas emissions. This study uses Data Envelopment Analysis to compute input-based technical efficiency measures and energy efficiency of Michigan greenhouse growers. A two-limit Tobit model is used to investigate the determinants of farmers’ performance. The empirical results indicate that Michigan greenhouse farmers do not use energy and other inputs efficiently. Farmers’ input-specific efficiency can be improved by adopting greenhouse film types other than double layer poly.
