DESCRIPTION:Despite recent improvements in the ecological status of wild-ca
 pture fisheries\, a significant share (33%) of global marine stocks remains
  overexploited. While top-down management has been shown to work in many se
 ttings\, there is growing interest in demand-side interventions\, which wor
 k through consumer-originated price signals to incentivize reduced fishing 
 pressure. The effectiveness of demand-side interventions would rely\, in pa
 rt\, on a large enough supply elasticity of fisheries\, though this crucial
  statistic is notoriously difficult to estimate and remains elusive in the 
 literature. Using plausibly exogenous variation in fish prices and extensiv
 e data on the world's fisheries\, we derive an empirical approach to estima
 te this elasticity using an instrumental variables estimator. We find it is
  very low -- similar to that observed in comparable sectors. This suggests 
 that even if prices did respond to demand-side interventions\, the supply r
 esponse would be small. To determine whether the ensuing supply response wo
 uld have meaningful ecological consequences\, we combine a bioeconomic mode
 l of fisheries with a global model of supply and demand for  seafood calib
 rated with our estimates. We find that even interventions that lead to dram
 atic demand shifts are unlikely to achieve more than marginal improvements 
 to fisheries status. In contrast\, we find that supply-side policies (such 
 as well-enforced fishing quotas)\, even imperfectly designed or implemented
 \, can result in substantial recovery. \\n\\nContact: Nicolas Clootens : n
