Most research on point-nonpoint trading focuses on the choice of trading ratio (the rate point source controls trade for nonpoint controls), although the first-best ratio is jointly determined with the optimal number of permits. In practice, program managers often do not have control over the...

Wildlife disease management strategies traditionally focus on lowering aggregate host density below a host-density threshold, reducing infectious contacts (when transmission is density-dependent) to reduce prevalence. The focus on "aggregate" host density is because controls such as harvests are...

We use a two-state linear control model to examine the socially optimal management of disease in a valuable wildlife population when diseased animals cannot be harvested selectively. The two control variables are nonselective harvests and supplemental feeding of wildlife, where feeding increases...
