Over the: past two decades, the marketing of fish has recognized the import
ance of quality. Yet empirical analysis of market transactions could give u
s little insight into the value of different qualities of fish because mark
et data are typically aggregated. We exploit a dataset on the auction price
of tuna sold in Hawaii to estimate a hedonic model. The model provides emp
irical estimates of price increments due to species, quality of the fish su
ch as size or fat content, method of handling, and market conditions. The e
mpirical results are also used to estimate price flexibilities for landings
in Hawaii.
