Appendix An excellent: Empirical model? ? Following the Shakya and you will Flinn (1985), the newest empirical design because of it studies try given as follows: Y* = ? + ? X + ? and you can Y = g(Y*) where Y=Y* to have Y* > 0 Y = 0, otherwise

Y* are a collection showing the new blend effectation of X (character specific and you may tech specific) items you to definitely determine use choice. Y* i s not observable. What’s, but not, observed is whether the brand new character enters into technology (whenever Y* >0) or perhaps not ( when Y* =0). In which Y is the town (ha) not as much as increased maize kinds, X is just as outlined over, ? , ? is variables getting projected and you will ? is a good stochastic error label The probability of use and employ intensity would be projected using the pursuing the conditional presumption setting: E(Y|Y*) = Y*.F(Y*/?) + ? .f(Y*/?
