Cost Analyses of Fish Price Margins, 1972-77, at Different Production and Distribution Levels

摘要

Each price margin of a fish product comprises cost and profits that are analyzed to estimate value added for the purpose of comparing economic contributions and productivities between sectors of each fishery and among fisheries. Costs are also regrouped to distinguish fixed from variable to assess the effect on profit, price, and production as a result of the alteration of cost structures.
