When the McDonald Corporation reduced the price of its Big Mac by 75 percent if customers also purchased french fries and a soft drink, The Wall Street Journal reported that the company was hoping the novel promotion would revive its US sales growth. It didn’t. Within two weeks sales had fallen. Using your knowledge of game theory, what do you think disrupted McDonald’s plans?

In my opinion, I believe McDonald's ingredients of french fries and the Big Mac have too much fat and is unhealthy for people because this can lead to obesity since it contains no nutrients.

I also believe what disrupted McDonald's plans is they only reduced french fries and soft drinks. They should of tried and balance the prices of each item they are selling.

I think that Mcdonalds was not thinking about competition and they should have

To analyze the situation using game theory, we need to understand the key players and their goals. In this case, McDonald's is the company implementing the promotion, and the customers are the other players.

The goal of McDonald's is to increase its sales growth in the US. They believed that by reducing the price of the Big Mac and requiring customers to also purchase fries and a soft drink, they would incentivize more people to buy the complete meal and lead to increased sales.

However, despite McDonald's efforts, the sales actually fell within two weeks. This outcome suggests that something disrupted McDonald's plans. There could be several factors that affected the results, and we can explore a couple of possibilities using game theory.

1. Customers' Preferences: It is possible that customers did not find the additional cost of fries and a soft drink worth the reduced price of the Big Mac. Some customers may prefer to have the flexibility to choose their side dishes and drinks independently, rather than being restricted to a bundle. This could have resulted in a decrease in overall sales.

2. Competitors' Response: McDonald's competitors might have reacted strategically to the promotion. They could have adjusted their own prices or introduced alternative promotions to counter McDonald's strategy. This competitive response might have caused customers to choose alternatives over McDonald's, thereby reducing their sales.

In game theory, we would analyze the different strategies and choices made by the players (McDonald's and customers) to understand the outcome. Factors such as price elasticity of demand, competition, and customer preferences would be important to consider in determining what disrupted McDonald's plans.

Ultimately, a more detailed analysis, including data on customer behavior and market dynamics, would be needed to provide a more definitive explanation of what disrupted McDonald's plans from a game theory perspective.
