| 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... |

| Resumen: El objetivo de este trabajo es medir el cambio de la productividad en la agricultura chilena durante el período 1961-96. La Productividad Total de los Factores (PTF) fue calculada mediante índices Törnqvist. Los datos utilizados para estimar estos índices incluyen precios y cantidades de 51 cultivos, de la mano de obra, de la tierra, del capital y de factores intermedios. El análisis revela que mientras los productos crecieron un 2,69% anual, el uso de factores de producción bajó un 0,09%; por lo tanto, la PTF creció a una tasa promedio anual del 2,78% entre 1961 y 1996. Se realizó además un análisis para siete períodos correspondientes a diferentes regímenes políticos. La PTF creció a un promedio anual de 1,83% con Alessandri (1961-64), 3,12%... |

| This paper evaluates the economic and the financial viability of implementing private farm management centers (FMC) in El Salvador. In doing so, an ex ante cost-benefit analysis is performed. The results of this analysis suggest that a combination of better farm prices (paid and received), reallocation of resources, and crop diversification that would be promoted by a FMC can lead to an increase in farm level profits that is sufficient to cover the operation of the center and to still generate net gains in household income. |

| This paper compares socioeconomic and technical characteristics of dairy cooperative members and nonmembers based on a sample of New England dairy herd improvement association participants. Descriptive statistics indicate there is a little difference between the two groups. A high proportion of members stated cooperatives were helpful primarily because they provide a safe or guaranteed market. Estimates of a Cobb0Douglas production function suggest membership in one specific cooperative was positively and significantly associated with average farm efficiency. Results of a logit analysis indicate the probability of being a cooperative member was positively related to extension contracts and negatively related to output per cow per farm. |

| This article reviews and critiques the frontier literature dealing with farm level efficiency in developing countries. A total of 30 studies from 14 different countries are examined. The country that has received most attention is India, while rice has been the most studied agricultural product. The average technical efficiency (TE) index from all the studies reviewed is 72%. The few studies reporting allocative and economic efficiency show an average of 68% and 43%, respectively. These results suggest that there is considerable room to increase agricultural output without additional inputs and given existing technology. Several of the studies reviewed have sought to explain farm level variation in TE. The variables most frequently used for this... |

| The objective of this study is to undertake a meta-analysis seeking to explain the variation in average technical efficiency focusing on the agricultural sector. For this purpose, a meta-analysis of 126 technical efficiency studies on the agricultural sector of developing and developed countries was undertaken. In addition, the study contributes to cross-country productivity literature because the existing body of work in this area typically uses aggregate (i.e., national) level data to estimate total factor productivity and has ignored the technical efficiency component of productivity. The econometric results suggest that stochastic frontier models generate higher mean technical efficiency estimates than deterministic models, while parametric frontier... |

| 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... |
