Technical Efficiency and Adoption of Soil Conservation in El Salvador and Honduras
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Solis,   Daniel; Bravo-Ureta,   Boris E.; Quiroga,   Ricardo E.
A household-level switching regression model is implemented to examine potential selectivity bias for rural households under high and low levels of investments in soil conservation in El Salvador and Honduras. In the presence of selectivity bias, separate stochastic production frontiers are estimated for low and high adopters. The main results indicate that households with higher levels of investments in soil conservation show higher average TE than those with a lower level of investments. Constrains in the rural land and credit markets are likely explanations for these differences. The results also indicate that for farms with lower levels of investments in soil conservation access to credit is a significant factor explaining the sources of inefficiency....

THE EFFECT OF SOIL CONSERVATION ON TECHNICAL EFFICIENCY: EVIDENCE FROM CENTRAL AMERICA
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Solis,   Daniel; Bravo-Ureta,   Boris E.; Quiroga,   Ricardo E.
This study evaluates technical efficiency (TE) levels for rural households under high and low levels of investments in soil conservation in El Salvador and Honduras. To correct for potential self-selectivity bias a household-level switching regression framework is implemented to estimate separate stochastic production frontiers for the two groups of households under analysis. The main results indicate that a systematic difference exists between the two studied groups. Specifically, households with higher levels of investments in soil conservation show higher average TE than those with a lower level of investments. Constrains in the rural land and credit markets appear to be the reason behind these differences. Our estimations indicate that for farms with...

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...

FARM BENEFITS AND NATURAL RESOURCE PROJECTS IN HONDURAS AND EL SALVADOR
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Cocchi,   Horacio; Bravo-Ureta,   Boris E.; Quiroga,   Ricardo E.
A model of conservation adoption, diversification and household income, including farm and off-farm sources was formalized, wherein households simultaneously allocate assets to different activities.  The mapping of assets to household income through both off and on farm activities can conceptually be considered as a production process, with assets corresponding to factors of production and income as the output.   Either adoption of conservation technologies and farm output diversification are influenced by participation in natural resource management programs.  Therefore, these technological improvements should foster farm production and productivity and, consequently, should be reflected in a greater household income,.  Finally, household income...
