On macroeconomic impact of fishing effort regulation: measuring bottom-up fish harvesters’ economy-wide contribution

This research develops a hybrid input-output model to quantify the economy-wide impact of capture fisheries on the economy. The method regards capture fisheries to be the “carrier branches” producing “core inputs”, which can drive the other fisheries sectors in the Ghosh supply-driven model. These fisheries sectors are all linked with the rest of the economy and can affect it through backward linkages in the Leontief demand-driven model. The empirical findings based on the Thai fisheries corroborate findings in other literature and further reveal that capture fisheries make a much greater contribution to the economy than is usually thought.
