Field experiment and household survey data are combined to investigate whether working in a risky occupation such as fishing makes fishermen have different risk preferences than individuals in other occupations. Prospect theory is utilized as the main analytical framework and a structural model approach is developed to simultaneously correlate the parameters of the utility function under prospect theory with other socioeconomic variables. The key finding is that working in fishing makes economic agents less risk averse than others. Fishermen also tend to be less sensitive to probability weighting changes in the experiment. It is possible that fishermen have adapted to their unique environment by using specific heuristics for decision making under conditions of uncertainty.

One of the most prominent features of remuneration in Hawaii’s longline fisheries industry has been the norm of share contract regimes. This paper investigates whether the use of the share contract regime is positively correlated to increased economic returns. The principal-agent framework is applied to develop a theoretical model for the remuneration choice. Empirical estimation is conducted using a switching regression model that accounts for the effects of certain vessel characteristics on revenue, depending on remuneration regime used (i.e., share contract or flat wage), as well as the potential selection bias in the vessels’ contractual choice. Key findings from counterfactual simulations indicate: (a) a negative selection related to choosing share contracts, and (b) flat wage vessels would experience significantly higher revenues if they switched to share contracts. Thus, even though the labor market in Hawaii’s longline fisheries relies upon foreign crew members, the results suggest that owners of flat wage vessels would benefit by applying share contracts to increase their revenues.
