Sam’s pasta is identical to the pasta made by dozens of other firms and there is free entry in the pasta. Buyers and sellers are well informed about prices.                       

  1. In what type of market does Sam’s operate?
  2. What determines Sam’s marginal revenue of pasta?
  3. If pasta sell for $5 a packet and Sam offers his pasta for sale at $5.50 a packet, how many packets does he sell?
  4. If pasta sell for $5 a packet and Sam offers his pasta for sale at $4.50 a packet, how many packets does he sell?
  5. What is the elasticity of demand for Sam’s pasta and how does it differ from the elasticity of the market demand for pasta?

Solutions

Expert Solution

A.

Sam is operating in perfectly competitive market, because products are identical in nature and there are many sellers with free entry in the market.

===

B.

It is the price that determines marginal revenue of pasta, because price = marginal revenue in this type of market.

===

C.

No sales takes place. ( no any packet of pasta will be sold)

Because, Sam is price taker seller in this market and he cannot charge a price that is higher to the price that is prevailing in the market.

So, price has to be $5 a packet.

===

D.

Sam will not sell at that price of $4.5

Because, market is prevailing at $5 price that will be taken up by Sam.

===

E.

It is perfectly elastic demand for Sam's pasta where value of elasticity is infinite (). It makes firm level demand curve to be horizontal in nature. It is different from market demand in perfect competition, as market demand is downward sloping in nature. It means that market demand exhibits elasticity that is not perfectly elastic.

Suppose that the perfectly competitive market for coffee beans is made up of identical firms with long-run total cost functions given by T C = 2Q 3 − 24Q 2 + 80Q , where Q is 100,000 pounds of coffee beans. Assume that these cost functions are independent of the number of firms in the market and that firms may enter or exit the market freely. Market demand is Q = 100, 000 − 400P (a) Find the long-run equilibrium...

Two identical firms compete in a Bertrand duopoly. The firms produce identical products at the same constant marginal cost of MC = $10. There are 2000 identical consumers, each with the same reservation price of $30 for a single unit of the product (and $0 for any additional units). Under all of the standard assumptions made for the Bertrand model, the equilibrium prices would be Group of answer choices $10 for both firms $30 for both firms $50 for both...
