The aim of this study is to explore theoretically the circumstances in which collusion can emerge between artisanal organizations and external agents. We also analyze theoretically how collusion can alter the sustainability equilibria of marine resources. In situations of incomplete information where external agents are not aware of the initial stock of resources, we observe how those agents decide whether to accept or reject offers of collusion from artisanal organizations.

Women's participation in small-scale aquaculture is growing, but women producers remain in a disadvantaged position compared to men. Reducing gender gaps is at the core of many development programs, but little is known regarding the source of these differences. This paper investigates the main drivers of gender gaps in seaweed small-scale aquaculture by focusing on the analysis of differences between male and women, and across a series of psychological traits.

Abstract

We study the development of aquaculture activities in Chile and the impacts of regulatory changes on location decision for aquaculture production centers. Our study considers a descriptive analysis on the spatial and temporal development of aquaculture production centers. Next, using a panel data we estimate a site selection model to explore determinant factors of site choices for aquaculture production. Our results suggest a clear pattern for the spatial-temporal development of Chilean aquaculture.

This study uses a choice experiment to characterize market segments (consumer preferences heterogeneity) based on three attributes of seafood (mussels) that are affected by ocean acidification: shell appearance, meat color, and nutritional composition. Using a sample of 1,257 individuals from two main cities in Chile, we estimate both the Mixed Logit model and the Latent Class model. We use the individual-specific posterior (ISP) parameters’ distribution to categorize consumers’ heterogeneity based on the signs and intensity (i.e., like or dislike dimension) of these ISPs.

The experiences of aquacultural firms regarding past environmental events and their present risk perceptions of environmental and social threats are key factors in understanding their adaptive response. This study aims to understand marine aquaculture firms' adaptive behavior considering firms' heterogeneity and the relationship between past experiences, present perceptions, and willingness to invest in adaptation.
