Increasing human interference with natural systems causes us to re-think our perception of wildlife species and the economic choices society makes with regards to their management. Accordingly, we generalize existing 'bioeconomic' models by proposing an economically-based classification of...

We build a stylized model to gain insights into the application of conservation payments to protect endangered species in the face of wildlife-livestock disease risks and habitat fragmentation. Greater connectivity of habitat creates an endogenous trade-off. More connectedness ups the chance...
