Impact of changes in the methodology of external price referencing on medicine prices: discrete-event simulation

Cost Effectiveness and Resource Allocation, 2020
Background Several governments apply the policy of external price referencing (EPR), which considers the prices of a medicine in one or more other countries for the purpose of setting the price in the own country.

Notions of Completeness in the EPR Discussion

Entropy, 2023
We explore the different notions of completeness applied in the EPR discussion following and amending the thorough analysis of Arthur Fine. To this aim, we propose a classification scheme for scientific theories that provides a methodology for analyzing ...
