Notes: Figures in each cell are based on a single regression. Each regression includes controls for: respondent’s age, education, gender, whether white, marital status, years since received nursing license, year and state effects, state unemployment rate, per-capita income, proportion elderly, proportion black, population growth (4-year change), hospital admissions per-capita (and its square) and outpatient visits per capita (and its square). Regressions are weighted by individual weight. Murphy-Topel standard errors that account for clustering at state-year level are in parentheses.
