“…Moura and Barros (2020) studies the price effects of competition in the market for OTC drugs, while Bennett and Yin (2019) studies the price and quality effects of the entry of pharmacy chains in a market dominated by low-quality firms.

We provide novel evidence of how public competition in the retail market affects equilibrium market outcomes.…”
