Our analysis suggests that reduced refuge requirements would enhance producer profitability, sprayed refugia are more cost effective than unsprayed refugia, and producers would receive slightly higher returns under dynamic relative to static refuge policies. Pyrethroid susceptibility in one of the pests was a renewable resource, and toxin-mixture effects associated with pyrethroid use in Bt cotton were important considerations for midsouth refuge policies.}, number={1}, journal={AMERICAN JOURNAL OF AGRICULTURAL ECONOMICS}, author={Livingston, MJ and Carlson, GA and Fackler, PL}, year={2004}, month={Feb}, pages={1–13} }

We used time-series data on pyrethroid tolerance and simple genetic models to estimate underlying genetic and biological parameters associated with resistance evolution in tobacco budworm, Heliothis virescens (F.), and bollworm, Helicoverpa zea (Boddie), Louisiana field populations. Assuming pyrethroid resistance is conferred by one gene at one locus in both species, inheritance of pyrethroid resistance was partially dominant in the tobacco budworm and partially recessive in the bollworm. Relative fitness estimates indicated that fitness costs associated with resistance selected against resistance alleles in the absence of selection pressure in the tobacco budworm, but not in the bollworm. In addition, relative fitness estimates obtained using the indirect method outlined in this study were similar in magnitude to estimates obtained using traditional direct approaches.}, number={5}, journal={JOURNAL OF ECONOMIC ENTOMOLOGY}, author={Livingston, MJ and Carlson, GA and Fackler, PL}, year={2002}, month={Oct}, pages={1008–1017} }

Headley uses 1963 state data to estimate a $4 return for each dollar of pesticide materials of all types (fungicides, herbicides, insecticides, etc.) used on U.S. farms. He indicates that this result helped explain the rapid increase in sales volume of pesticides. But during the 1960s producers were giving additional attention to pest control as more insect species became resistant to more chemical types. Many policy questions on the limitation of use and registration of insecticides require more detailed knowledge of the demand for specific compounds. Regulatory officials are concerned about the substitutability of other chemical and nonchemical pest controls (Davis et al.). Yet, no statistical estimates of insecticide demand are presently available. The importance of insecticide resistance in affecting demand for specific compounds and the long-run productivity of insecticides are investigated in this paper. Individual farm data from several cotton production regions and aggregate insecticide use data are used to test hypotheses of falling productivity of insecticides and substitutability between chemical types.}, number={3}, journal={AMERICAN JOURNAL OF AGRICULTURAL ECONOMICS}, author={CARLSON, GA}, year={1977}, pages={543–548} }

Control of mobile weeds, insects or contagious diseases has characteristics of a public good with high exclusion costs and near equal availability to all people in the affected area. If abatement benefits for areas to which the pest is spreading are not considered, there will be under production of abatement. Cooperatives, county abatement districts or state and federal agencies are often set up to administer area-wide abatement efforts. Economies of scale in pesticide treatments, coordination of efforts to limit spatial spread of the pest (quarantine activities) and scale economies in technology to reduce adverse side effects of pesticides are given as justifications for public or large-scale pest control programs.}, number={2}, journal={Southern Journal of Agricultural Economics}, author={Carlson, G.
