Observations are facility-months. HPRD = hours per resident day, measured as the average of daily total nursing assistant hours divided by daily resident census, across all days in the month. High Medicaid share facilities are those where at least 75% of residents are covered by Medicaid. Robust standard errors (clustered by locality) are reported in parentheses. Statistical significance is indicated by ^*** p < 0.01, ^** p < 0.05, ^* p < 0.1. All models also include the monthly county unemployment rate, facility fixed effects, year-by-month fixed effects, state fixed effects, and state-by-fiscal year fixed effects
