      abstract = {This article analyzes how information use affect farm  productivity and efficiency. Our hypothesis is that farmers  make better decisions when they use information (for  example, choosing a high value crop combination or selling  the products at higher prices) and that will enhance on  productivity and efficiency. We use two techniques to  mitigate the possible biases generated by observable and  unobservable variables: Propensity Score Matching (PSM) for  the first one and the stochastic production function (SPF)  approach corrected by sample selection for the second one.  We take advantage of the underused Peruvian National  Agricultural Survey (ENA) which includes information about  12 877 farmers located in the Andean region. Our results  show that farmers who use information are systematically  nearer to their frontier than those who do not use  information (0.50 vs. 0.47, on average). The analysis by  plot size and age suggest that farmers with smaller plots  and those who are middle age are more efficient in the  users group; however, the relation is not clear among the  nonusers of information. Thus, more research is needed  about the complementarity of the agricultural inputs and  information use. These results can contribute to the design  of a cost-effectiveness evaluation of information extension  programs.},
