Credible enforcement policies under illegal fishing: does individual transferable quotas induce to reduce the gap between approved and proposed allowable catches?

摘要: In general, approved Total Allowable Catches (TACs) are higher than proposed TACs by the scientific assessment and reported landings TAC. We build a simple enforcement agency’s behavior model that generates—as rational behavior—those two facts. The has ingredients. First, there exists illegal fishing generated an imperfect technology; second, agency cannot commit on announced penalties. show lack of commitment increases potential benefits for national deviating from proposal (scientific optimal) quotas. Although wants to announce low quota target induce level harvest, it will find optimal revise in order reduce penalties improve fishermen welfare. Therefore, agencies approve quotas advice. Our main result is when full compliance not possible, commit, introduction Individual Transferable Quotas TAC advised.
