What type of Market Structure is Pfizer?

Pfizer operates in an oligopolistic market structure within the pharmaceutical industry. This is characterized by a few large firms dominating the market, significant barriers to entry, and product differentiation through patents and brand recognition. Pfizer, along with other major pharmaceutical companies, invests heavily in research and development to innovate and maintain a competitive edge. This environment allows them to exercise some degree of pricing power while facing competition from both other large firms and generic drug manufacturers.
