Entry and competition of retail pharmacies: A case study of OTC drugs sales and ownership deregulation1.

This study provides new empirical evidence on the changes in competition and entry decisions of pharmacies after regulatory changes. It investigates the development of the retail pharmacy market in Portugal, which underwent major regulatory changes in 2004 and 2007. Sale of OTC drugs and ownership of pharmacies were liberalized while entry restrictions related to market size and the location of new pharmacies prevailed. Our empirical strategy was based on entry models and provided indirect information on the toughness of competition and entry decisions of firms in the market. We estimated and compared the entry thresholds and their ratios before and after liberalization. Such a comparison allows to see if competition got tenser with OTC drugs deregulated. There were three main findings from the study. First, the entry thresholds decreased regardless of the number of pharmacies in the market, suggesting that room for the realization of profits is broader than it was in the past. Second, although the entry thresholds were lower in value, their increase was steeper with each incumbent in 2020, suggesting harsher price competition with new entrants. Third, the current rule of 3,500 patients per pharmacy is likely overly restrictive, pharmacies could break-even even in smaller markets.

Market structure and competition in the healthcare industry : Results from a transition economy.

The present paper provides first empirical evidence on the relationship between market size and the number of firms in the healthcare industry for a transition economy. We estimate market-size thresholds required to support different numbers of suppliers (firms) for three occupations in the healthcare industry in a large number of distinct geographic markets in Slovakia, taking into account the spatial interaction between local markets. The empirical analysis is carried out for three time periods (1995, 2001 and 2010) which characterise different stages of the transition process. Our results suggest that the relationship between market size and the number of firms differs both across industries and across periods. In particular, we find that pharmacies, as the only completely liberalised market in our dataset, experience the largest change in competitive behaviour during the transition process. Furthermore, we find evidence for correlation in entry decisions across administrative borders, suggesting that future market analysis should aim to capture these regional effects.
