The goal of this research is to estimate, using semi parametric (SNP) techniques, the recreational benefits related to one strategic ecosystem of high moors in Colombia. This technique was used during the travel cost method estimation process due to its flexibility. The chosen SNP technique corresponded to the Fourier flexible form, adjusting a Poisson model, such that the truncation and endogenous stratification biases in the data base could be taken into account.
This paper investigates the efficiency of carrot and stick policies to reduce investment in coca cultivation in rural Colombia. To measure behavioral responses to anti-drug policies, we conducted a framed field experiment with farmers living in one of the most important coca growing areas. Our experimental design allows identifying heterogeneous producer types and measuring their behavioral response to carrots and sticks. We provide an example on how knowledge on distribution types can be used to design an optimal anti-drug policy.
