Abstract
This article presents a simple combination discrete-time/continuous-time model that incorporates continuous population dynamics and fishing activity together with periodic, rather than continuous, instrument adjustment into the decision process for choosing the optimal type and level of regulatory instrument. A per-unit tax and an allocated instantaneous harvest rate quota each drive the system along different time paths, and each results in a different present value of the stream of net benefits generated by harvesting the resource. The choice of instruments is fishery specific; it depends on the parameter values of the fishery in question.Environmental Economics and Policy, Resource /Energy Economics and Policy,
