Conventional theory says that innovations first diffuse slowly, then at faster paces, and finally at asymptotically declining rates. Economists and others explain such behavior with a variety of logistic models. Early models like the contagion model derive their predictive power from reliance on...

In this paper, we suggest a Stata routine for multinomial logit models with unobserved heterogeneity using maximum simulated likelihood based on Halton sequences. The purpose of this paper is twofold. First, we describe the technical implementation of the estimation routine and discuss its...

Se describe la estructura analitica de los modelos de adopcion de innovaciones tecnologicas mas utilizados en la literatura, haciendo hincapie en las aplicaciones agricolas desde el punto de vista del empresario agrario, y se analiza empiricamente como se ha difundido la tecnologia de riego...
