M4A2: Expected Value and Consumer Choices

(All Articles are attached. They must be used and TurnItIn is used to check all papers.)

 

Consumers’ choices are prey to subtle discrepancies that arise in cognitive accounting. Learning how and when you are prey to these discrepancies is an important step in improving your decision making.

As the readings for this module demonstrate, people value gains and losses differently under different scenarios. For example, contestants in a game show might choose a guaranteed $10 prize over a 50 percent chance of winning $20 despite the fact that the expected values are the same.

Using the readings for this module, the Argosy University online library resources, and the Internet, address the following:

  • What is mental accounting and how does it impact consumer decision making?
  • How might a company take advantage of consumers’ mental accounting? Give examples.
  • As a marketer, how might you frame certain decisions to benefit from the disparities that arise in one’s cognitive accounting?
  • As a consumer, how would you avoid the pitfalls posed by the inequalities of one’s cognitive accounting?

Write a 3–5-page paper in Word format. Apply APA standards to citation of sources. Use the following file naming convention: LastnameFirstInitial_M4_A2.doc.

Assignment 3: Marketing Scenario Analyses

Southern Baptist Hospital (SBH) had long resisted the use of marketing, believing it was not an appropriate activity for a nonprofit organization. By the mid-1980s, however, the erosion of its market share due to growing competition forced SBH to adopt an aggressive marketing strategy.

Its primary initiative was a campaign of television advertisements aimed to reinforce for the general public the image of SBH as a high-quality institution. Because the organization was starting its marketing activities from scratch, ad production and airtime costs were expensive. The television commercials were professionally produced and received critical acclaim from the advertising community.

Following the public’s repeated exposure to these advertisements, a hospital executive requested information about the impact of the advertisements. The idea to study the campaign’s impact had not been considered earlier, and a belated evaluation effort was mounted to determine the extent to which the campaign had achieved the desired effect. Much to the consternation of SBH administrators, the evaluation found that the ads had had virtually no impact on the public’s already high perception of the institution, and no improvement in patient volumes, revenues, or market share could be attributed to the campaign. SBH administrators, committed to an expensive initiative, rationalized that the campaign had not aired long enough to generate the desired effect and invested even more money in the initiative.

After reviewing the above case, address the following points:

  1. To what extent did SBH research the needs of its audience prior to developing a marketing strategy? 
  2. Does it appear that SBH has an overall marketing plan? 
  3. Does it appear that SBH had a significant grasp of the nature of marketing?
  4. What are the implications of focusing marketing efforts on corporate image rather than the services the organization provides? 
  5. What are the implications of marketing to the general public rather than targeting specific segments of the market? 
  6. How much thought was given to measuring the effectiveness of the campaign going into the initiative?

Post your responses in a 2- to 3-page Microsoft Word document.
