Appendix A great: Empirical design? ? After the Shakya and you can Flinn (1985), the brand new empirical model because of it investigation was specified below: Y* = ? + ? X + ? and you may Y = g(Y*) in which Y=Y* getting Y* > 0 Y = 0, otherwise
Y* is actually a collection highlighting new mix effectation of X (farmer specific and tech particular) activities one to determine adoption decision. Y* i s perhaps not observable. What is, yet not, noticed is whether this new farmer gets into the technology (when Y* >0) or perhaps not ( whenever Y* =0). In which Y ‘s the city (ha) below enhanced maize kinds, X can be as defined more than, ? , ? are variables to get projected and you will ? is a stochastic error label The possibilities of use and make use of intensity will be projected by using the following conditional expectation mode: E(Y|Y*) = Y*.F(Y*/?) + ? .f(Y*/?
