This paper uses data from small-scale potato farmers in Ecuador to examine the impact of the program Plataformas de Concertación on productivity growth. Using propensity score matching combined with a Stochastic Production Frontier model that corrects for sample selection bias, we disaggregate...

In poverty reduction programs, a significant number of beneficiaries change program status. An analysis of Oportunidades’ data from urban Mexico shows that beneficiaries that drop out for behavioral and administrative reasons are those who are marginally eligible, improving targeting through...

In this study the authors analyze the degree of output diversification (anything produced in the farm that is not a subsistence crop, i.e., corn or beans) among 520 hillside farmers in El Salvador. Techniques were employed to construct a comparison group that resembles the treatment group based...

This paper examines the determinants of adoption of soil conservation technologies among farmers participating in the Environmental Program of El Salvador (PAES). A sample of PAES participants was surveyed in 2002, from which a sub-sample was re-surveyed in 2005 along with a control group of...

This study examines the extent to which technical efficiency (TE) is related to activities promoted by two natural resource management programmes recently completed in Central America. Data for a total of 639 farms operating in the hillsides of El Salvador and Honduras are used to estimate a...

This article analyzes the determinants of farm income among hillside farmers participating in natural resource management projects in El Salvador and Honduras. The farm income function was evaluated using a system of equations in which income is determined simultaneously by the farmer's decision...

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...

This paper examines the determinants of adoption of soil conservation technologies among farmers participating in the Environmental Program of El Salvador (PAES). A sample of PAES participants was surveyed in 2002, from which a sub-sample was re-surveyed in 2005 along with a control group of...

A meta-regression analysis including 167 farm level technical efficiency (TE) studies of developing and developed countries was undertaken. The econometric results suggest that stochastic frontier models generate lower mean TE (MTE) estimates than non-parametric deterministic models, while...

This study uses contingent valuation to determine consumer’s willingness-to-pay (WTP) for reducing hydrilla in two alternative spring-fed river systems in Northwest Florida - the Wacissa River (an open access park) and the Wakulla Springs (a gated park). Two dissimilar payment vehicles -gate...
