Week Three Student Guide
This week’s topics include how supply and demand, revenue, profit maximization, and the various
cost concepts apply to different market structures. When introducing the market structures, the
readings and discussions illustrate why different firms might utilize different techniques to
increase business—that is, which business types would utilize pricing strategies and nonprice
strategies to meet goals, which businesses need to consider advertising and what type of
advertising, and which businesses may need to consider cost-reduction strategies to improve
profitability.
