Sample size | 211 | 176 |

- (***) p < 0.01; (**) p < 0.05; (*) p < 0.10
- All models include as controls total current health expenditure, population, country’s income classification data, life expectancy, percentage of people above age 65. In the lag-models, to control for time-variant unobservable factors, parameters are estimated using two waves of data resulting in a smaller sample size. All missing variables for the control variables were imputed at the mean value and a corresponding dummy for missing was added. Robust standard errors were computed
