On the economics of biological invasion: An application to recreational fishing
The paper demonstrates four general mechanisms that may affect economically valuable species when exposed to biological invasion. We distinguish between an ecological level effect and an ecological growth effect. In addition we present an economic quantity effect working through demand. Finally we s...
