Parameter values that were used to calculate the functions shown in Fig. 1 for the Exponential (EXP), Hyperbolic (HYP), Rachlin hyperboloid (RACH), and Myerson-Green hyperboloid (MG)

Model	Shallow	Steep
EXP	$k=.06$	$k=.30$
HYP	$k=.10$	$k=.80$
RACH	$\mathrm{k}=.10$	$k=.80$
	$\mathrm{s}=.50$	$s=.50$
MG	$k=.10$	$k=.80$
	$s=.50$	$s=.50$

Separate parameters are shown for the shallow discounting curves in the top panel and the steep curves in the bottom panel of Fig. 1. See Table 1 for parameter definitions
