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.

Local response to global uncertainty: insights from experimental economics in small-scale fisheries.

Global change has systematically increased uncertainty for people balancing short-term needs with long-term resource sustainability. Here, we aim to understand how uncertainty drives changes in human behavior and the underlying mechanisms mediating use of behavioral strategies. We utilize a novel behavioral approach – dynamic common-pool resource economic experiments in the field – and apply it to small-scale fisheries as a system that is particularly vulnerable to global change.

Vulnerability of socio –ecological systems: A conceptual framework

The analysis of vulnerability of socio-ecological systems to threats of different types such as extreme climate events or change in land use draws attention to the factors and processes that determine whether the ecological, social and integrated socio-ecological systems are likely to experience harm due to exposure to the threat.

The demand for air quality: evidence from the housing market in Bogotá, Colombia

Identifying a demand function for air quality is a key input to calculate welfare measurements of pollution abatement policies. We defined intra-urban housing submarkets to apply a Second Stage hedonic pricing model that allowed us to identify an inverse demand function for PM10 reductions in Bogotá. The monthly benefits of compliance with the U.S. Environmental Protection Agency standard (50 μg/m3 – annual average), and the far more stringent World Health Organization standard (20 μg/m3 – annual average) are valued at US$12.16 and US$189.64 per household, respectively.

Peace is much more than doves: The economic benefits of bird-based tourism as a result of the peace treaty in Colombia

Colombia has the greatest bird diversity of any country in the world, with approximately 1900 recorded species, equivalent to 20% of all bird species worldwide. Advances made by the Colombian government to achieve greater security within the country – putting an end to the long-standing armed conflict – and to promote ecotourism can help position Colombia as one of the most important bird watching destinations worldwide. This study estimates the economic benefits from bird-based tourism in post-war Colombia.

Efecto de la variabilidad climática sobre la demanda de agua para uso residencial urbano: el caso de la ciudad de Manizales, Colombia

Un modelo estructural consistente con la teoría de la utilidad se usó para derivar funciones de demanda de agua para uso residencial urbano en la ciudad de Manizales, Colombia. Características del hogar y la vivienda recolectadas en una encuesta, así como información de precio, ingreso, precipitación y una variable dummy para indicar si el mes correspondía a la fase cálida de El Niño,se incluyeron en la estimación econométrica de la demanda de agua para uso residencial urbano.
