Empirical analysis of the factors that determine individual compliance with a locally devised set of rules for harvesting and selling marine turtle eggs, as well as for protecting the turtles and their hatchlings. Rules violators receive a monetary penalty, which implies a reduction in the income from sale of eggs. While some individuals do not have income reductions due to infractions, others have reductions of up to 40% of the total income. Using written records of deductions due to sanctions between May 2008 and May 2010 and information from a survey of 108 local turtle egg harvesters, the paper presents the results of econometric analyses of factors that influence the amount of fines received by individuals. The results suggest that individual dependence on the income from sale of eggs, perceptions of rules and their legitimacy, and demographic factors such as age and gender are all important factors explaining rule breaking behavior. The findings also highlight new threats to the long-term survival of local institutions responsible for protection of marine turtles and their sustainable consumptive use
