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...

Where joint forest management has been introduced into Tanzania, ‘volunteer’ patrollers take responsibility for enforcing restrictions over the harvesting of forest resources, often receiving as an incentive a share of the collected fine revenue. Using an optimal enforcement model, we...

Lake Victoria fisheries are important to Tanzanian food security, employment, and foreign exchange, but they are experiencing declining performance largely due to overfishing. This paper studies technical efficiency and skipper skill using Tanzanian fishery data for the two major species, Nile...

Where participatory forest management has been introduced into Tanzania, “volunteer” patrollers take responsibility for enforcing access restrictions, often receiving a share of the fine revenue that they collect as an incentive. We explored how this shared revenue and alternative sources of...

REDD (Reduced Emissions from Deforestation and Degradation) aims to slow carbon releases caused by forest disturbance by making payments conditional on forest quality over time. Like earlier policies to slow deforestation, REDD must change the behaviour of forest degraders. Broadly, it can be...

This paper explores the impact of the re-introduction of access restrictions to forests in Tanzania, through participatory forest management (PFM), that have excluded villagers from forests to which they have traditionally, albeit illegally, had access to collect non-timber forest products...

In low-income countries, both nearby local villagers, “insiders”, and non-locals, “outsiders”, extract products from protected forests even though their actions are illegal. Forest managers typically combine enforcement and livelihood projects offered to nearby communities to reduce this...

We study dynamic labour supply using data on paua (abalone) divers in New Zealand. The divers face stable, flat prices per kilogram after each catch, but experience transitory wage changes due to varying weather and water conditions, and are free to vary their daily working hours and display an...
