Hedonic Price Model of Hawaiʻi ʻAhi Tuna (Thunnus obesus and Thunnus albacares) Market: Implications of Climate Change and Shark Depredation

In Hawaiʻi, the prices of ʻahi tuna, i.e., bigeye tuna and yellowfin tuna (Thunnus albacares), are influenced by numerous factors. This study utilizes a hedonic price model to estimate tuna price using fish characteristics, trip-specific information, daily market conditions, foreign imports, individual seller effects, and time effects. The study also estimates the price impact of shark depredation and assesses its negative effect on revenue.
