Extensive margin effects

	Any initial prescription (×100) (1)	Days MED in initial prescription (2)
Limits	0.100 (0.022)	0.055 (0.035)
PDMP	−0.054 (0.015)	−0.035 (0.053)
α = β	0.000	0.303
Mean DV	1.155	0.593

Notes: Table reports estimates of the coefficients on indicators for “initial prescription limits” and “must access PDMPs”, obtained from estimating OLS regressions of the indicated variables against policy indicators, state fixed effects, and month-year fixed effects. MED is morphine equivalent days. The row labelled α = β reports p-values of the hypothesis that the coefficients on MA–PDMP and Limit are equal. Robust standard errors, clustered on state, in parentheses.
