  abstract = {{T}his paper examines the {M}anta ({E}cuador) market for landings and imports of skipjack, bigeye, and yellowfin tunas through estimation of an inverse almost ideal demand system. {S}kipjack landings and imports dominate the market. {M}anta tuna market prices show inflexible price responsiveness to changes in quantities of own species for all imports and landings except yellowfin imports. {S}imultaneously reducing landings and imports of all species increase vessel profits but is more than countered by economic welfare loss of supply chain firms, ex-porters, and consumers for a net decline in {E}cuador's economic welfare. {R}esults show two distinct but linked market segments: (1) one well integrated by price with mutually substitutable skipjack imports and skipjack, yellowfin, and bigeye landings and dependent on skipjack imports, and (2) a niche segment centered around yellowfin imports for processors. {I}f the {B}angkok market still retains primary global price leadership, it also re-sponds to the growing {M}anta market.},
