Notes: All models estimated with OLS. Standard errors are clustered at the state level and are reported in parentheses. Model (1) controls for state demographics, state fixed effects, and period fixed effects (baseline model). Model (2) controls for state demographics, state-specific linear time trends, state fixed effects, and year fixed effects. Model (3) controls for state and year fixed effects. Payment source state sample includes the following states: AK, AR, CO, DC, HI, IA, ID, KS, KY, MO, MS, MT, ND, NE, NH, NJ, NV, OH, PA, RI, SC, SD, TX, UT, and VT. Standard errors are clustered at the state level and are reported in parentheses.
