"Why Don’t Farmers Always Follow IPM? Economics of Pest Scouting and Information Acquisition" with David A. Hennessy (Job Market Paper)
Abstract: Threshold-based integrated pest management (IPM) has been promoted for decades, yet adoption remains incomplete. Threshold rules indicate when to treat once pest information is available, but not whether acquiring it is worth the cost. We model scouting as acquisition of a costly, imperfect signal. Scouting is privately worthwhile when the signal can change treatment, and its expected value covers scouting cost. Calibrated with untreated soybean aphid trials and Iowa economic data, information can change treatment in 12 of 56 plot-seasons, and in 11 of those its value covers scouting cost. Information can change treatment over a narrow range of aphid densities, and most observed pest paths never enter it. Lower scouting costs can make existing information opportunities worthwhile, whereas greater signal accuracy broadens the conditions under which information can change treatment. The practical reach of threshold-based IPM therefore depends on both the treatment rule and the economics of acquiring the information needed to apply it.
