Tobacco-Free Pharmacies is a term used to refer to retail pharmacies where the sale of tobacco products is not available.
 Outside the United States, it is rare for pharmacy stores to sell cigarettes and similar products on the same premises as over-the-counter drugs and prescription medication.
 Anti-tobacco campaigners advocate the removal of tobacco from pharmacies due to the health risks associated with smoking and the apparent contradiction of selling cigarettes alongside smoking cessation products and asthma medication.
 Some pharmaceutical retailers counter this argument by reasoning that by selling tobacco, they are more readily able to offer to customers advice and products for quitting smoking.

Competitive heterogeneity is a concept from strategic management that examines why industries do not converge on one best way of doing things.
 In the view of strategic management scholars, the microeconomics of production and competition combine to predict that industries will be composed of identical firms offering identical products at identical prices.
 Deeper analyses of this topic were taken up in industrial organization economics by crossover economics/strategic-management scholars such as Harold Demsetz and Michael Porter.
 Demsetz argued that better-managed firms would make better products (or similar products at lower costs) than their competitors.
 Such firms would translate better products or lower prices (an optimal decision based on lower costs) into higher levels of demand, which would lead to revenue growth.
 These firms would then be larger than the more poorly managed competitors.
 Porter argued that firms in an industry would cluster into strategic groups.
 Each group would be similar and movement between groups would be difficult and costly (barriers to mobility).
 Richard Rumelt and Stephen Lippman demonstrated how firms could differ in an industry in partial equilibrium-like circumstances.
 Richard Nelson and Sidney G. Winter discussed how firms develop differing capabilities.
 During this time, industrial economics focused on industry characteristics, treated the differences among firms in an industry as trivial.
 This was a point of contention within strategy and between strategy and economics from about 1980 to the mid-1990s.
