Resumen
Descripción
Recent increases in the harvests of southern bluefin tuna, particularly by Australian fishermen, have led to the recognition that the fishery is overexploited. A model is developed to examine the effects that quotas on Australian and Japanese harvesting would have on economic welfare and on stock levels. Recursive quadratic programming is used to simulate harvesting decisions through time, with and without the imposition of quotas.
