Table 3.

Elasticity differences by drug categories

	Mean elasticity	Std. Dev.
Acute drugs	−0.14	0.25
Chronic drugs	−0.41	0.71
Non-maintenance drugs	−0.04	0.27
Maintenance drugs	−0.28	0.51
Branded drugs	−0.32	0.64
Generic drugs	−0.14	0.15
Predominantly non-maintenance class^a	−0.10	0.09
Predominantly maintenance class^a	−0.17	0.17

Table reports (unweighted) average (and std. dev.) estimated elasticities for different subsets of drugs (and therapeutic classes). See on-line appendix for details of how these classifications are constructed.

We consider a class as “predominantly maintenance” if the majorty of the associated drugs are classified as to maintenance drugs; in most therapeutic classes all drugs are either maintenance or not.
