4. (16 points) Company A has been selling 200 units per month of a product at a price of $12 per unit. The two competitors of Company A have also been selling that product at $12 per unit. The manager of Company A is now considering increasing the price of this product by $2.40.

(a) Assume that the category price elasticity in this product category is -0.90. If Company A's two competitors match the $2.40 price increase, what is the price elasticity that Company A should expect? Explain your reasoning.

(b) If Company A's two competitors do not match Company A's price increase and maintain their current prices, would the price elasticity that Company A should expect be greater or be lower than the one you gave in Part (a)? Give an example of that greater or lower price elasticity. Then, using the course material, explain your reasoning.

(c) If Company A's two competitors adopted a cooperative stance, what would most likely be their response to Company A's price increase? Describe three pieces of information about Company A's two competitors that would help Company A determine if they would adopt a cooperative stance in this situation.

(d) How would you get the information you mentioned in Part (c)? Describe three of the sources of competitive information that were discussed in the course material and explain why each of these sources would be able to provide relevant competitive information.
