This paper examines the impact of coinsurance exemption for prescription medicines applied to elderly individuals in Spain after retirement. We use a rich administrative dataset that links pharmaceutical consumption and hospital discharge records for the full population aged 58 to 65 years in January 2004 covered by the public insurer in a Spanish region, and we follow them until December 2006. We use a difference-in-differences strategy and exploit the eligibility age for Social Security to control for the endogeneity of the retirement decision. Our results show that this uniform exemption increases the consumption of prescription medicines on average by 17.5%, total pharmaceutical expenditure by 25% and the costs borne by the insurer by 60.4%, without evidence of any offset effect in the form of lower short term probability of hospitalization. The impact is concentrated among consumers of medicines for acute and other non-chronic diseases whose previous coinsurance rate was 30% to 40%. Copyright
