Stability of International Fisheries Agreements Using Precautionary Bioeconomic Harvesting Strategies

International Fisheries Agreements with a Shifting Stock

When a fish stock shifts from one nation to another nation, e.g. due to climate change, the nation that loses the resource has incentives to deplete it while the other nation, receiving the resource, has incentives to conserve it. We propose an analytical model to study under which circumstances self-enforcing agreements can align incentives. Our setup allows to distinguish between a fast and a...

Harvesting fisheries management strategies with modified effort function

In traditional harvesting model a fishing effort E is defined by the fishing intensity and does not address the inverse effect of fish abundance on the fishing effort. In this paper, based on a canonical differential equation model, we developed a new fishing effort model which relies on the density effect of fish population. This study concludes that a control parameter β( the magnitude of the...

Economic perspective of marine reserves in fisheries: a bioeconomic model.

The present paper describes a prey-predator type fishery model with prey dispersal in a two-patch environment, one of which is a free fishing zone and other is protected zone. The objective of the paper is to maximize the net economic revenue earn from the fishery through implementing the sustainable properties of the fishery to keep the ecological balance. Biological measures are introduced to...

Compliance with International Agreements

The study of compliance with international agreements has gained momentum over the past few years. Since the conclusion of World War II, this research agenda had been marginalized by the predominance of realist approaches to the study of international relations. However, alternative perspectives have developed that suggest that international law and institutions are important influences on the ...
