RT Journal Article SR Electronic T1 Sodbusting, Crop Insurance, and Sunk Conversion Costs JF Land Economics JO Land Econ FD University of Wisconsin Press SP 601 OP 622 DO 10.3368/le.90.4.601 VO 90 IS 4 A1 Miao, Ruiqing A1 Hennessy, David A. A1 Feng, Hongli YR 2014 UL http://le.uwpress.org/content/90/4/601.abstract AB We build a real option model that articulates sodbusting incentives arising from risk interventions in the presence of conversion costs. The model shows that risk interventions reduce expected costs of switching land use between cropping and noncropping activities and, hence, incentivize sodbusting. Based on data for south-central North Dakota over 1989–2012, our simulations show that offsetting 20% of a cropping-return shortfall by a risk intervention increases the sodbusting cost threshold, below which sodbusting will occur, by 41% (or $43.7/acre). Omitting cropping-return risk across time underestimates the sodbusting cost threshold by 23% (or $24.35/acre) and hence underestimates sodbusting caused by crop production. (JEL Q18, Q38)
