摘要：To determine the advantages and disadvantages of co-payment for visits to physicians, it is important to quantify the effect of co-payments on the number of consultations. The article uses a change in the co-payment system from 2010, when adolescents between 12 and 15 no longer had to pay a co-payment, in order to estimate the effect of co-payment for this age group. Using a difference-in-difference model and comparing against changes in other age groups, the elimination of co-payments is estimated to have increased GP visits by 13 and 18 percent for males and females respectively. Placebo tests show that the results are robust.
