To determine

The necessary conditions for perfect completion market to exist

Expert Solution & Answer
Check Mark

Explanation of Solution

In perfect competition market, neither a single producer nor a single consumer can determine the operation of this market. It offers efficiency in both allocation and production. The necessary conditions for this market to exist are:

  • A large number of buyers and sellers:

    There are so many customers that one customer can purchase a very small portion of the market supply; likewise a single seller can provide a very small fraction of the total output too. Hence in relation to the sector it belongs, the size of the competitive firm is very small.

  • Homogenous products:

    All suppliers provide a homogenous product in a perfect competition market, in simple words all the competitive firm's products are the same.

  • Perfect information:

    Buyers, as well as sellers, have complete knowledge of the current market price. That is why in a perfect competition market there can only be one price.

  • No barriers to entry or exist:

    A new business can freely enter into this particular type of market or an existing business can freely leave the industry in the longer term.

  • Cheap and efficient transportation:

    Another feature of competitive market is low priced and efficient transport. Firms do not incur substantial costs in transporting goods in this type of market. This reduces the cost of the product and lessens the delays in the transportation of goods.

Richard has just opened a new restaurant. Not being good at deserts, he has contracted with Carla to provide pies. Carla’s costs are $10 per pie, and she sells the pies to Richard for $25 each. Richard resells them for $50, and he incurs no costs other than the $25 he pays Carla. Assume Carla’s costs go up to $30 per pie. If courts always award expectation damages, which of the following statements is most likely to be true?
Difference-in-Difference In the beginning of 2001, North Dakota legalized fireworks. Suppose you are interested in studying the effect of the legalizing of fireworks on the number of house fires in North Dakota. Unlike North Dakota, South Dakota did not legalize fireworks and continued to ban them. You decide to use a Difference-in-difference (DID) Model. The numbers of house fires in each state at the end of 2000 and 2001 are as follows: Number of house fires in Number of house fires in Year North Dakota 2000 2001 35 50 South Dakota 54 64 a. What is the change in the outcome for the treatment group between 2000 and 2001? Show your working for full credit. (10 points) b. Can we interpret the change in the outcome for the treatment group between 2000 and 2001 as the causal effect of legalizing fireworks on number of house fires? Explain your answer. (10 points)
C. Regression Discontinuity Birth weight is used as a common sign for a newborn's health. In the United States, if a baby has a birthweight below 1500 grams, the newborn is classified as having “very low birth weight". Suppose you want to study the effect of having very low birth weight on the number of hospital visits made before the baby's first birthday. You decide to use Regression Discontinuity to answer this question. The graph below shows the RD model: Number of hospital visits made before baby's first birthday 5 1400 1450 1500 1550 1600 Birthweight (in grams) a. What is the running variable? (5 points) b. What is the cutoff? (5 points) T What is the discontinuity in the graph and how do you interpret it? (10 points)
