Chapter 7 1) For each of the following graphs, identify the firm’s profit-maximizing (or loss minimizing) output. Is each firm making a profit? If not, should the firm continue to produce in the short run?
In the first graph, the firm is losing money, but it should not shut down because P > AVC. So the loss minimizing choice is to stay in business in the short run. To shut down would lead to higher losses equal to fixed costs and these losses would be more than the current losses.
In the second graph, the firm is realizing a profit because P > ATC. Consequently, it should continue to operate as long as P > AVC.
In the third graph, the firm should shut down because P < AVC. This is its loss minimizing choice as the

c) Show and explain the long-run adjustment process for both the firm and the industry. What will happen to the number of firms in the new long-run equilibrium?
As the number of organizations increase, the industry supply curve shifts to the right denoted by S2. In the long run, firms will be operating at minimum of ATC and economic profit will be zero again. Long run prices will be equal to initial price (p1) and the equilibrium quantity will be higher. Companies will likely have similar cost structures and will grow in quantity over time. Prices cannot go below this because companies will exit at prices below this level.
Chapter 8:
1) Given the demand curve in the following graph, find (and label) the monopolist’s profit-maximizing output and price.
The profit maximizing output is found by locating where the marginal revenue equals the marginal cost. Then the demand curve will show the price where the profit maximizing output will be demanded.
3) Suppose the demand curve for a monopolist is QD = 500 – P, and the marginal revenue function is MR = 500 – 2Q. The monopolist has a constant marginal and average total cost of $50 per unit.
a) Find the monopolist’s profit-maximizing output and price.
To maximize profits, a monopolist sets his output in such a way that
Marginal Revenue = Marginal Cost
Given
MR=500-2Q
MC=50
Put MR=MC
500-2Q=50
2Q=450
Q=225
To
This graph is specific to an oligopoly and shows the change in quantity demanded in relation to the change in price for both elastic and inelastic goods. Total Revenues will be increased, if the firm decreases their price but increase their quantity. Due to the fact that the costs remain the same, the revenue line on the graph can be seen to be steeper than the costs meaning that the profit is higher. The graph therefore also indicates the point where the firm is able to make the most amount of profit, in relation to the price they set and the quantity they produce.
d. Calculate the price elasticity of demand in each market and discuss these in relation to the prices to be charged in each market.
Explain how a profit maximizing firm determines its optimal level of output, using marginal revenue and marginal cost as criteria:
* In Assignment 1, you determined your firm’s market demand equation. Now you need to find the inverse demand equation. Having found that, find the Total Revenue function for your firm (TR is P x Q). From your firm’s Total Revenue function, then find your Marginal Revenue (MR) function.
(7) A monopolist can discriminate prices for his product, a firm working under perfect competition cannot. The monopolist will be increasing his total profit by price discrimination if he find? Elastic ties of demand are different in different markets.
a.) Draw and properly label the demand and supply graphs (this means you must label the axes and any lines you include on the graph).
The food trucks affected the local production curves for the restaurant meal industry by drawing more customers to their food truck meal industry. The more customers the food truck meal industry have, the lesser the restaurant’s customers would have. Therefore, the restaurant’s customers would decrease as the food truck’s customers increases and the business will eventually fail. For example, if initially, the restaurant meal industry doesn’t have a competition with the food truck meal industry, they have 200 customers a day and 0 customers for the opponent. And when Bobby started his food truck business, he drew 120 new customers to his new food truck that attracted 50 of the customers from the restaurant. Another food truck joined, and the customers increased to 170. The more food trucks and the faster they evolve, the more customers would be attracted, consequently, 0 customers left for the restaurant meal industry—the business fails.
1. Please conduct a financial ratio analysis using the data in Exhibit 2. How do the results reflect different strategies pursued by the 4 firms?
In the short run the perfect competition equilibrium can be found by graphing the marginal cost (MC), average total cost (ATC) and marginal revenue (MR) curves. In perfect competition the price is equal to the average revenue, which is equal to the marginal revenue and these are all constant, giving an infinitely elastic demand curve for the firm. The demand curve is “perfectly price elastic” due to the homogeneity of the products supplied, where each supplier, as a price taker, must focus on a single price. Given this, the only choice a supplier has in the short run is how much to produce. For profit maximisation to occur marginal costs (supply curve) must equal marginal revenue (demand curve). Profit maximisation is assumed to mean the maximisation of normal economic profit (i.e. revenue that covers the
