    Regulatory Compliance in Lake Victoria Fisheries
    (Environment and Development Economics, 2010) Eggert, H.; Lokina, Razack B.
    This paper analyzes the causes for regulatory compliance, using traditional deterrence variables and potential moral and social variables. We use self-reported data from 459 Tanzanian artisanal fishers in Lake Victoria. The results indicate that the decision to be either a non-violator or a violator, as well as the violation rate – if the latter – are influenced by changes in deterrence variables like the probability of detection and punishment and also by legitimacy and social variables. We also identify a small group of fishers who react neither to normative aspects nor to traditional deterrence variables but persistently violate the regulation.

    Small-Scale Fishers and Risk Preferences
    (Marine Resource Economics, 2007) Eggert, H.; Lokina, Razack B.
    Using an experimental approach, we investigate the risk preferences of artisanal fishermen in Tanzania waters of Lake Victoria. The experiment concerns pairwise comparisons of hypothetical fishing trips that vary in expected mean and spread of the net revenue. The results show that about 34% of the fishermen can be considered as risk neutral, 32% as risk averse, and 34% as risk seekers. Econometric analysis indicates that the likelihood of belonging to the risk-seeking group increases if motorboats are used, if fishing is the main source of household income, and if the fisherman is targeting Nile perch. Asset ownership and perhaps socioeconomic variables influence risk preferences.

    Trade and Resources: Welfare effects of the Lake Victoria fisheries boom
    (Elsevier, 2012-01) Eggert, H.; Greaker, Mads; Kidane, Asmerom W.
    In this paper we examine the welfare implications of the Tanzanian fisheries boom following from the increase in quantities and prices of the Lake Victoria Nile perch export during 1993-2008. We use the theoretical model by Brander and Taylor (1997) that we try to test empirically. We have a micro level perspective using data from a 1993 World Bank household survey and our own study from 2008, both containing data from about 520 households in the two regions Mwanza and Mara by the lake. Our results indicate that average income has increased in both rural and urban areas. For the poorest part of the population, rural areas experienced only modestly and non-significantly reductions in the fraction below basic needs, while urban areas had a substantial reduction. However, growth was modest and inequality seems to have increased during the period. Concerning human capital measured as education for the household head we found substantial improvements in educational level and a simple regression model confirmed the significant impact of education on household income. We also found that households on average are better off when situated close to the lake.
