Soil conservation and technical efficiency among hillside farmers in Central America: a switching regression model
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Solis,   Daniel; Bravo-Ureta,   Boris E.; Quiroga,   Ricardo E.
The main objective of this paper is to evaluate and analyse technical efficiency (TE) levels for hillside farmers under different levels of adoption of soil conservation in El Salvador and Honduras. A switching regression model is implemented to examine potential selectivity bias for high and low level adopters, and separate stochastic production frontiers, corrected for selectivity bias, are estimated for each group. The main results indicate that households with above-average adoption show statistically higher average TE than those with lower adoption. Households with higher adoption have smaller farms and display the highest partial output elasticity for land. Constraints in the land and credit markets are likely explanations for these differences. In...

Technological Change and Technical Efficiency for Diary Farms in Three Countries of South America
Provedor de dados: Chilean Journal of Agricultural Research
Autores: Bravo-Ureta,Boris E; Moreira,Víctor H; Arzubi,Amilcar A; Schilder,Ernesto D; Álvarez,Jorge; Molina,Carlos.
The progressive liberalization of agricultural markets, along with the threat that imported products can pose to local producers, reveals the importance of productivity growth as a mechanism to improve competitiveness. Technical efficiency measurement is the most studied component of productivity because it can help to generate valuable information for policy formulation and farm level decisions focused on the improvement of farm performance. This study uses unbalanced panel data sets for dairy farms from Argentina, Chile and Uruguay, to estimate stochastic production frontier models. These frontiers are then used to estimate economies of size, technological change and technical efficiency. All estimations are based on the Battese and Coelli (1992) model,...
