In this paper we measure the value of sanitary restrictions in terms of forgone profits. For this we model the trade-off between biosecurity and profits in the salmon aquaculture industry. We introduce the concept of “sanitary desirable volume” of the salmon industry, as a goal in a bi-objective model. We...
This paper analyzes the distributional consequences of re-distributing quota between different artisanal fisher groups (from large vessel to small vessel owner) when management is based on a collective rights system. We develop a basic model to analyze optimal decisions with a collective fishing rights system. With this model as a...

This research analyzes the effects that a redistributive fishing quota policy, within a collective rights quota assignment system, might have on the profits and employment of artisanal fisher organizations. The Chilean authorities have been pursuing a deliberate quota redistributive policy between ship-owners of different vessel categories. This policy has affected...
This paper analyzes the equity consequences of different fishing quota distributions among artisanal fisher organizations. We develop a basic model to analyze optimal decisions with a collective fishing rights system. With this model as a conceptual framework, using a Theil index as a distributive measure, and employing optimization techniques we...
This paper measures the impact that the sanitary treatments aiming to reduce the abundance of sea lice Caligus rogercresseyi have on the unit production costs of Atlantic salmon fattening centers in Southern Chile. We make use of unique data that allows us to follow complete production cycles for a sample...
We apply the Fishery Performance Indicators (FPIs) methodology to the Southeast Pacific Anchoveta Fishery off southern Peru and northern Chile. Our basic model of analysis is a production function framework, where the performance outcomes are a result of the available inputs. We measured all FPI categories (outcomes and input metrics)...
This paper analyses evidence about fishermen collectively organized bargaining over ex-vessel prices with a monopsony-like buying sector. Government allocation of collective catch quotas to fishermen organizations triggered the voluntary formation of cooperative fishermen’s bargaining associations, while a highly concentrated processing sector started behaving as a countervailing monopsony. This drove ex-vessel...
This report reviews previous studies and presents original data on the
biology, habitat, fisheries biology and fisheries oceanography of the jack
mackerel fishery of Chile, and has been written as a contribution for a future management of this fishery.
This thesis contains three manuscripts addressing the application of stochastic processes to the analysis and solution of partial differential equations (PDEs) in mathematical physics.
In the first manuscript, one dimensional diffusion and Burgers equation are considered. The Fourier transform of the solution to each PDE is represented as the expected...
