“…3 and 4) have been shown to fit the discounting of monetary outcomes better than the simple hyperbolic and exponential models (McKerchar et al, 2009;McKerchar, Green & Myerson, 2010), researchers have not, as yet, fully explored which function provides the best fit to the discounting of environmental outcomes. Evidence has been presented to support the exponential (e.g., Hannon, 1994), the hyperbolic (e.g., Kaplan et al, 2014;Viscusi, Huber, & Bell, 2008b), and hyperboloid functions (e.g., Berry, Friedel, et al, 2017;Berry, Nickerson, & Odum, 2017;McKerchar, Kaplan, Reed, Suggs, & Franck, 2019) for the discounting of environmental outcomes, but model fit comparisons in relation to environmental outcomes are rare. Research exploring best-fitting model functions to the data of individuals in environmental discounting tasks is even scarcer.…”
