Do you think that the typical drug firm possesses any market power based on market structure? Explain.

Yes the typical drug firm possesses a market power based on oligopoly market structure. Oligopoly is the market structure that best describes the Drug Firm. This is because:

There are few large firms in the drugs producing industry and it is more competitive markets.
There are high entry and exit barriers in this industry, such as huge costs, government licensing, and others.
Firms do not indulge in price wars; instead, they compete on the grounds other than prices such as advertisements, services, discounts, and others.
Firms are interdependent, which means that each firm has the capability to affect the decisions of other firms and have power to influence market conditions.
