Valuing a water recreation facility using semi parametric estimators in the travel cost method

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.

Production risk and adoption of irrigation technology: evidence from small-scale farmers in Chile

In most developing countries non-irrigation status often dominates adoption of traditional and modern irrigation technology. In this paper, we study the effect of production risk on irrigation technology choice among small-scale farmers in Chile, applying sample selection and discrete choice models. We find that more educated farmers, with credit access, receiving extension services, and living in communes with more adopters are more likely to use modern irrigation techniques.

Weather shocks and cropland decisions in rural Mozambique

Economic development in low income settings is often associated with an expansion of higher-value agricultural activities. Since these activities often bring new risks, an understanding of cropland decisions and how these interact with shocks is valuable. This paper uses data from Mozambique to examine the effect of weather shocks on cropland decisions. We account for the bounded nature of land shares and estimate a Pooled Fractional Probit model for panel data. Our results show that crop choice is sensitive to past

Share Contract Choices and Economic Performance: Empirical Evidence from the Artisanal Fisheries Sector in Chile

Typically, crew members in fisheries are remunerated through a share of the total revenues. However, there is little empirical evidence on the mechanisms by which revenues are distributed to labor and capital, and how these distributions affect economic performance. Under an agency problem framework, we estimate a dose-response function to study the formation of contracts and identify the marginal effects of changes in crew profit shares on fishing returns in Chilean artisanal fisheries. The results support share contract choices

Exploring typologies of artisanal mussel seed producers in southern Chile

Aquaculture is on the most dynamic food production systems in the world, with a fast expansion, especially in developing countries.  Among this sector, the Chilean mussel industry has experienced a substantial increase, turning Chile into one of the leading producers and global exporters of mussels.  Among the different links in the mussel production chain, the natural seed collection conducted by artisanal fishers of southern Chile has been a fundamental pillar for the development of the industry.  Often, this sub-sector  has been thought of as a  homogeneous group

The Impact of Caligus Treatments on Unit Costs of Heterogeneous Salmon Farms in Chile

We measure the impact that sanitary treatments that control ectoparasite Caligus rogercresseyi abundance have on unit production costs of Salmo salar farms in Chile. We follow complete production cycles for a sample of farms between 2009 and 2015. We estimate a simultaneous salmon biomass growth and Caligus abundance model. The statistical analysis determines the effect of antiparasitic treatments, location of farms, environmental conditions, and Caligus abundance on the salmon growth profile.

Sorting through Affirmative Action: Three Field Experiments in Colombia

The use of affirmative action policies to promote female employment remains debated. Do affirmative action policies attract female applicants, and does that come at the expense of deterring highly qualified male applicants? In three field experiments in Colombia, we compare job seekers who are informed of affirmative action selection criteria before they apply with those who are told after applying. We find that the gains in attracting female applicants far outweigh the losses in male applicants.

Organization performance with in-group and out-group leaders: an experiment

In this paper, we compare the performance of a homogeneous organization in which group members and the leader belong to the same group, with a heterogeneous organization in which the leader is an outsider. Using a modified public goods game in which leaders’ performance in a real effort task determines the marginal return to the public good we focus on the effect of shared group membership on: i) the effort of the leader in the real effort task, ii) cooperation of group members and iii) group members’ payoffs.
