Final answer:
Marketers use various strategies to address off-season periods, including adapting production, setting flexible prices, adjusting operational scale, and introducing new products. These can increase demand or profit margins without relying solely on advertising.
Step-by-step explanation:
Marketers can use strategies other than advertising to smooth out "off-season" periods. For instance, monopolistically competitive firms might look into options like expanding or reducing production, adjusting prices with the flexibility to set the price they choose, opting to open new factories or sales facilities or close them, hiring workers or laying them off, or deciding to start selling new products or to discontinue existing ones.
These strategies can help a company either to increase demand directly or to capture more value from the demand that exists.
Advertising is a critical factor in this as well, with the main goal being to differentiate a firm's products from those of their competitors. It can be thought of in two ways: it either makes the demand curve more inelastic or it increases the overall demand by shifting the demand curve to the right, which either way can lead to higher sales volume or prices and thus boost profits.
