The paper analyses the economic payoffs from marine reserves using a stochastic optimal control model. The results show that even if the reserve and harvested populations face the same negative shocks, harvesting is optimal, the population is persistent and with no uncertainty over current stock...

Using data from what was once one of the world’s largest capture fisheries the economic value of a marine reserve is calculated using a stochastic optimal control model with a jump diffusion process. The results show that with a stochastic environment an optimal-sized marine reserve can...

We contribute to the understanding of marine reserves and the management of renewable resources with uncertainty. We show that the key benefit of reserves is that they increase resilience, or the speed it takes a population to return to a former state following a negative shock. Resilience can...

Using data from what was once one of the world’s largest capture fisheries, the northern cod fishery, the economic value of a marine reserve is calculated using a stochastic optimal control model with a jump-diffusion process. Counterfactual analysis shows that with a stochastic environment an...

Standard tests of the Harrod-Balassa-Samuelson (HBS) hypothesis treat productivity levels in and across countries as fixed and observable, and offer little empirical support for the hypothesis. If productivity follows a jump-diffusion process, these standard tests will generate biased estimates,...

Surveillance programs on farms and in the local environment provide an essential protection against the importation and spread of exotic diseases. Combined with border quarantine measures, these programs protect both consumers and producers from major health concerns and disease incursions that...
