Weighted sample. Std errors in (). Table reports the coefficients on dummy variables in an OLS regression indicating two discontinuity points at the median of the sample on either side of the cut-off, namely 3 years before and 2.4 years after the introduction of the QOF. All regressions include: a linear function of month of interview, and its interaction with the placebo reform dummy, and age, age squared, gender, educational qualification, number of children, marital status and income.
