Suppose that the potential customers for hair braiding in a city consider hair braiding to be identical and that the market is perfectly competitive. Hair braiding requires special skills so the supply of workers in this industry is upward-sloping, and the wages earned by hair braiders increase as the industry output increases. Firms in this market face the following total cost:

TC = Q³ – 8 Q² + 20Q + W

where, Q = number of hair braidings,

W = daily wage paid to workers, which depends on total industry output, equals W = 0.1NQ, where N = total # of firms.

Market demand is:

Q^D = 500 – 20P.

Find the long-run equilibrium output for each firm. (3 marks)

Find the long-run equilibrium number of firms (N), total industry output (NQ), and price (P).
(6 marks)

Suppose demand increases to Q^D = 1,000 – 10P. Find the new long-run competitive equilibrium.

Consider a mid-size city of 3,000,000 people in the Cairo city . Suppose that its residents produce, on average, 6.0 kg a day of MSW. At present this waste is being hauled 180 miles away (in a southeasterly direction) where it is being used to fill in an abandoned open pit nickel mine. The mine and deposited wastes abut a shallow marine embayment. Seaweed, shellfish, crustaceans, and fish are harvested from this embayment and eaten by both the local fishermen...

Consider a firm that is introducing a new product. The firm identified 300 potential customers whose probability of purchasing the product depends on age and gender as follows: Female Under 60 Probability Buy 0.6 Not 0.4 Female Over 60 Probability Buy 0.4 Not 0.6 Male Under 60 Probability Buy 0.55 Not 0.45 Male Over 60 Probability Buy 0.45 Not 0.55 Using the spreadsheet of customer data provided, estimate the average number of product demand in each city: New York, Chicago,...

Consider a monopolist airline with 100 potential customers, 10 of which are business travellers and 90 of which are tourists. A business traveller is willing to pay 1000 for a first class seat, and 500 for an economy class seat. A tourist is willing to pay 400 for a first class seat and 300 for an economy class seat. The marginal cost of an economy class seat is 200, the marginal cost of a first class seat is 400. (a)...

Consider the linear city model. Suppose there are 1,000 people uniformly distributed along the city, which is 10 km long. Each customer buys 1 unit. Suppose firm one is located 1 km left of the centre and firm two is located 2km to right of the centre. Each firm has a marginal cost of zero. Suppose also that the customers have a travel cost of $5 per kilometre. 1. Sketch firm A’s demand curve for the cases in which firm...

Suppose I own a store and am only interested in increasing the number of potential customers that enter my store. Further, I believe that advertising could influence how many people enter my establishment. Based on past experience with similar stores, I estimate the following relationship between the number of customers (C) and the amount of advertising (A) to be: C = 100 + 6A – A²/100. a. Graph this function and describe (in economic terms!) the intercept and slope. b....

Customers arrive at a hair salon according to a Poisson process with an average of 16 customers per hour. The salon has just one worker due to covied-19 restriction. Therefore, the salon must close whenever the worker leaves. assume that customers who arrive while the salon is closed leave immediately and don’t wait until the worker returns. The salon is closed on weekends. a. What is the probability that at most (less than) four customers arrive in the hour before...

Consider the daily market for hot dogs in a small city. Suppose that this market is in long-run competitive equilibrium with many hot dog stands in the city, each one selling the same kind of hot dogs. Therefore, each vendor is a price taker and possesses no market power. The following graph shows the demand (D) and supply (S = MC) curves in the market for hot dogs. Place the black point (plus symbol) on the graph to indicate the...
