Testing for Input Substitution in a Regulated Fishery
通过计算受限制与未受限制投入之间的替代程度，检验投入管制能否防止渔业租金耗散，并以不列颠哥伦比亚省鲑鱼渔业数据证明投入替代的存在，质疑管制方案的有效性。
Abstract Input restrictions are commonly used to prevent rent dissipation in fisheries. This paper examines whether these schemes are successful by calculating the degree of input substitution between restricted and unrestricted inputs. Conventional elasticities of substitution cannot be used when the firm faces controls on the use of some inputs. In this case, the appropriate measure of substitution, the elasticity of intensity, must be used. Data from the British Columbia salmon fishery provide evidence of input substitution possibilities for two vessel types. These results call into question the usefulness of input control schemes.
