This paper is concerned with the estimation of stochastic frontier production functions with unbalanced panel data when unobservable firm efficiency levels are related to explanatory variables. ≪We use the weighted-means≫ Instrumental Variables method acknowledged to R. Gardner (1998) which...

Consider a stochastic frontier model with one-sided inefficiency u, and suppose that the scale of u depends on some variables (firm characteristics) z. A “one-step” model specifies both the stochastic frontier and the way in which u depends on z, and can be estimated in a single step, for...

This study estimates a stochastic production frontier to measure technical efficiency (TE) using farm-level survey data for a random sample of small-scale farmers in Central Chile. Socioeconomic and productive information was collected in season 2005/06 through a survey of 319 farmers in the...

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...

The paper is concerned with supply constraints in the provision of telecommunications services. As a measure of supply constraint we use the average waiting time for telephone connections. Duration models are employed to analyze a panel data set for 28 countries. In addition to economic...
