Effectiveness of the Pasture, Rangeland, and Forage Rainfall Index (PRF‐RI) Program: Interval Selections With Uniform Premium Subsidy Rates

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT This study examines interval selection in the Pasture, Rangeland, and Forage Rainfall Index (PRF‐RI) program and evaluates how uniform premium subsidy rates affect optimal interval selections. Using South Dakota as a case study, we show a trend of increasing selection of nonproduction intervals from 2013 to 2024, raising concerns about program
