Notes: Only coefficients of the main explanatory variable are reported. The dependent variable is the number of admissions by type, and the explanatory variables are the dummy variables for whether the local government imposed an income cap and whether it imposed minimal user charges, regional average income, time fixed effects, and individual fixed effects. Robust standard errors are clustered at the municipality level and reported in brackets. ACSC ambulatory care sensitive condition
