However,we also have good reason to believe that the technology of organic and conventional farming may be similar in small and undeveloped rural areas, since poor farmers face a similar environment and cannot easily improve their production means by simply switching to organic farming during such a short time. Themajor difference between organic and conventional farming is reflected by the amount of inputswhich are modeled by the translog production function. In otherwords, organic farmingwould not directly, but rather indirectly, influence productivity through the efficiency terms (i.e., TE and EE). If this is the case, a two-stage analysis is appropriate (Battese & Coelli, 1995). Therefore, to ensure the relevance of technical efficiency fromthe beginning,wewill need to performa preliminary statistical test to determine the right specification of our production function as follows:
