Cooperation, Spatial-Dynamic Externalities, and Invasive Species Management
Epanchin-Niell, Rebecca S.; Wilen, James E. - Agricultural and Applied Economics Association - AAEA - 2010
Most terrestrial biological invasions occur in landscapes comprising numerous, independently managed properties. Thus, control of invasion spread generally depends on the choices of many managers, each deciding the extent to control invasions on their property. Here we develop a...

Optimal control of spatial-dynamic processes: The case of biological invasions
Epanchin-Niell, Rebecca S.; Wilen, James E. - Agricultural and Applied Economics Association - AAEA - 2010
This study examines the spatial nature of optimal bioinvasion control. We develop and parameterize a spatially explicit two-dimensional model of species spread that allows for differential control across space and time, and we solve for optimal control strategies. We find that the qualitative...

Eradication of Exotic Weeds in Australia: Comparing Effort and Expenditure
Hester, Susan M.; Odom, Doreen I.S.; Cacho, Oscar J.; … - School of Economics, Business School - 2004
Weeds have many adverse impacts on agriculture and the environment and therefore are often targets of eradication … attempts. Eradication attempts involve large commitments of labour and financial resources over significant periods of time …. Using data from 12 Australian weed eradication attempts the authors compare work hours and expenditure on each attempt for …

Prevention or Control: Optimal Government Policies for Invasive Species Management
Kim, C.S.; Lubowski, Ruben N.; Lewandrowski, Jan; … - In: Agricultural and Resource Economics Review 35 (2006) 1
We present a conceptual, but empirically applicable, model for determining the optimal allocation of resources between exclusion and control activities for managing an invasive species with an uncertain discovery time. This model is used to investigate how to allocate limited resources between...
