MAXIMUM BALANCE OF PROFIT: MONOPOLY
1. If an industry is to be classed as a pure (or perfect) competition, says that there are two basic requirements.It argues that when these two conditions are met, the result is individual company, a demand curve is almost horizontal, ie perfect or almost perfect elastic with respect to price. The company is free to sell as much or as little as they please at a price of market in which no control.
Very few companies in real life are in this position. This is because (as this chapter argues) the failure of one or both of the two requirements basic perfect competition. In real life, ie the number of companies can be too much (big / small) for perfect competition. In addition, products sold by different companies may be (identical among all the companies and differ from one company to another).
(I) many small companies, (ii) all sales identical products:
small: distinguished from one company to another.
2. These two characteristics, too small a number of vendors and / or differentiation of competitive products, are said to have "monopoly" effects.
Note note that the word "monopoly" does not mean that the companies involved are monopolies. The conventional definition of a monopoly situation the following: (i) only one company in the sector, and (ii) has no close substitutes available for the product of that industry a business.
Except in one of the special few such as utilities, the approximation of the real monopoly cases are almost as hard to find as in the case of perfect competition. Monopoly is a kind of extreme example of the imperfection competitive. The economist Edward H. Chamberlin, who did much to develop the ideas in the first part of this chapter, argued that the typical situation in real life is a "monopoly
competition. "Each company believes it has to have competition from close substitutes (so that not a monopoly), and yet his situation is not of pure or perfect competition.
The word "monopoly" is used because it is argued that there is a characteristic of monopoly, as found in all cases of monopolistic or imperfect competition.
less than perfectly elastic with respect to price, ie they are "lean" rather than horizontal.
3. If the number of sales firms is small, the name given to the resulting situation is
If the number of sales is big business, but competition is not perfect, it must be (in the language of text) to a situation
Oligopoly many different vendors.
In its opening sections, the chapter text describes the circumstances of imperfect or monopolistic competition. But do not try to explore these situations in any real detail. Instead, after its introduction scheme, The chapter makes a review of the profit-maximizing behavior of a monopoly firm. Analytically, this case is decidedly monopoly easier than the so-called "intermediate" cases-those who are not in perfect competition, monopoly and still not well. It would be unwise to make address these more complex cases before they have mastered the basic ideas of monopoly prices.
Even the terms and diagrams that are involved in a description monopoly price may seem complicated at first. However, the basic idea is simple involved. The monopoly firm is assumed to behave in order to "maximize their profits, "which is exactly what the firm in pure (or perfect) competition is assumed. The monopoly firm only operates in quite different circumstances.
To review the basic ideas of "profit maximization"
1. "Maximizing the benefit," making as much money as the supply conditions permit.
2. To "maximize profits", there must be something the company can do to influence their benefit. There must be some variable that changes for profit, and that the company can control.
3. In this chapter assumes that the monopoly can control how much you sell, as well as on a pure (or perfect) competition can do. (In real life, this control is the best indirect and incomplete, there are other, more complex decisions to make. But this chapter deals with a simple case.) Therefore, the variable that the monopoly firm can control is your unit of sale: it looks for the amount of sales in particular as to maximize its profit.
4. The monopoly firm is assumed that control their amount of sales because he knows the demand curve for its product, ie, knows the amount of sales that goes with each and every price you can collect.
5. From this demand curve, it is easy to develop a program of revenue (Total Revenue quantity sold multiplied by the unit price), ie a table showing the revenues associated with each sale as possible.
6. The company should also know the total cost of each and any amount of production. By bringing together the revenue and costs, then you can identify the amount of output in excess of revenue over cost (profit) is higher. (And you can tell the price charged for the production of this maximum profit by consulting only the demand curve once again.)
For repeat capture the essence of this sequence of ideas is that simple. Only when the monopoly profit-maximizing "position equilibrium "(with respect to sales and price of output) is described in marginal terms that can seem complicated. But these marginal terms are essential tools for analysis, when one moves to more complex situations. Hence the emphasis on marginal revenue and marginal cost in the section of text and questions in the review below.
4. Columns (1) and (2) Study Guide Table 1 represent a demand curve. This calendar has calculated or estimated by the company as an indication of the amounts that can be sold every day at different prices.
Table 1
The company must operate under conditions of (perfect / imperfect) competition, since the output sold increases, the price (constant / must be reduced).
5. We treat the first two columns of Table 1, which represents the monopoly of demand for a timetable. Our task is to determine what price the monopolist charge, and what outputs are produced and sold, if your goal is most useful.
o. Column (3) of Table 1 shows the total revenue of price times quantity. Completes the four blanks in this column.
Then, use columns (2) and (3) figures to illustrate the total income of the Study Guide Fig. 1-ie, total revenues are associated with various output quantities. Join the points with a smooth curve. Ignore for a moment the TC had called the curve in Fig. 1.
?. Note that this demand curve becomes inelastic prices, when the price is low enough, specifically, when the price reaches $ (8/7/6/5/4).
The bar graph (a) and (2) Table 2 and is drawn in Figure 1 as a total cost curve (TC). (check the curve indicated in question 5 as TR, as distinguished from the curve costs.)
Now you can see at once by the process that maximizes the benefits described here is simple. The firm is doing nothing more than to find out where the vertical distance between TR and TC is greatest. This distance, for any output is (fixed cost, price or profit or loss). (If TR is above TC, which is profit, if TC is above, is the loss. "So it is preferable to seek" greater distance vertical "with? Above CT. The longest distance with? leading brands on the maximum possible loss, which is somewhat less desirable as a position of operation.)
6. Figure 1 is too small to indicate rapidly the exact position of maximum profit. But even a look is enough to indicate that this-is the best possible position i.45/65/85) about the production units.
The company can be seen as gradually increasing its production and sales, stopping at each increase to see if their position is best benefit. Each additional unit production brings
a little more income (if the demand has not vet moved to price-inelastic range), and each additional unit incurs at a cost little more. The position of the company's profit improvement if this small amount of extra income (above / equal to / less than) small amount of additional cost.
More elegant words, production should be higher, since it resulted in an increase in profits, if marginal revenue (MR) (superior / equal to / less than) Marginal Cost (MC). The company must reduce its production and sales if it finds that MR (Exceeds / equals / is less than) MC.
And so the "balance position" is where the Lord is (unless than / equal / greater) MC.
7. A more careful development of the idea of marginal revenue is needed. Column (4) in Table 1 shows the additional number of units sold if the price is reduced. Column (5) shows the additional revenue (positive or negative) resulting from the reduction in price. Complete spaces in both columns to familiarize yourself with the meanings involved.
8. The profit-maximizing rule is: Enlarge output to the level of output at which MR = MC and stop at that point.
The rule of maximizing profits for the company in the purest (Or perfect) competition: P = MC. This is just a special case of MR = MC rule. It is assumed in the pure (or perfect) competition that the demand curve facing the individual firm is perfectly horizontal, or perfectly price (elastic / inelastic). That is, if the price market is $ 2, the firm receives (less than $ 2 / $ 2/more exactly $ 2) for each additional unit sold. In this special case, MR (income additional unit) is (greater than / same as / less than) the price per unit (which could be called average income, or revenue per unit). Thus, pure (or perfect) competition, P == MR = MC and MC are two ways of saying the same thing.
9. In the competition imperfect, firm demand curve is - and things are different. From the inspection of the figures in Table 1 [compare columns (1) and (6)] is Clearly, with such a demand curve, in particular MRI, any output is (more than / the same as / less than) the price of this product.
Why is this so? Suppose that, at a price of $ 7, you can sell four units, at a price of $ 6, 5 units. Revenue associated with these two prices are respectively, $ 28 and $ 30. Marginal revenue from the sale of the fifth unit is therefore $ (2/5/6/7/28/30). Is the difference in revenue generated as a result of the sale of one extra unit. Why only two dollars, when the selling price at the fifth unit was 86? Due to sell the fifth unit, the price had to be reduced. And this reduced price applies to five units. The first four, which previously sold at $ 7, now bring only $ 6. In this account, the revenues takes a beating $ 4. You must subtract $ 4 cans of the $ 6 that the fifth unit comes in. This leaves a net gain in revenue income of $ 2-marginals.
10. To return to the fate of the company in Tables 1 and 2: The tables do not provide sufficient detail to show unit by unit the exact level maximum output gain. But Table 1 shows that sales of products between 63 and 71, MR is $ 1.63. MR sales figures fall as they expand, so the $ 1.63 is applied near the midpoint of this range, for example, exit 67. It would be somewhat higher between 63 and 66, somewhat lower between 68 and 71.
Similarly, MC (Table 2) SI.60 in the output of about 67 units. So the maximum position of profit would fall very close to 67 units produced and sold per period.
To sell this product, the firm would charge a price (see table 1) of about 8 (7 '5 .75/4/1.60). His Revenue [Total figures in the immediate search in column (3)] would be approximately $ (380/580/780). The total cost (Table 2) would be more or less ^ (310/510/710), giving earnings per period of about $ 70.
$ 5.75, $ 380 and $ 310.
11. The text states that marginal revenue in geometric terms can be represented as the slope of the curve of total revenue.
12. Boxes can be better understood more carefully considering the total revenue curve you have drawn in the Study Guide of the figure. 1. Figure Study Guide. 2 shows an enlargement of a small segment of the curve: the curve between the production quantities of 25 and 31. If 25 units are sold, the price is 810 and total revenue is $ 250. This is point A in Fig. 2. If the price drops to $ 9, which increases sales by 6 units, from 25 units to 31 units. Thus, the total income becomes $ 279 (31 times $ 9). Therefore, if the company reduces the price from $ 10 to $ 9, in fact, moves from point A to point B.
Figure 2 is heavier line curve is the smooth curve to connect the dots A and B. This is an approximation of the points to be gained if we have the quantity and the revenue and on price as 59 90, S9.SO, and so on.
There is also a straight line (thin line), which binds A and B. It is located near the probably true total revenue curve, although it is unlikely that the exact curve.
Instead of dropping $ 10 from price all the way to $ 9, suppose who had moved only to (say) $ 9.60. That would have produced (approximately) an increase of 2 units in quantity demanded. Thus, we approach MR true figure to our previous 6-approximation service. In Fig. Two terms, we would be moving from a single
D no, from A to B. Note carefully that the straight line (thin line) joining the A to D becomes better or worse) approach (of the total revenue curve presumed true in the case when the matters involved were A and B.
In short, the closer we move point B to point A (for example, if we make rather than D B), the closer the figure is yet to be a measure of truth contained MR. In fact, we have real MR (the rate of change in income measured in terms 1-unit change in production) only when the line whose slope is measured and used to indicate the RM is actually tangent to the total revenue curve.
In its last section I, near closing and the margins, the chapter of the text emphasizes that if a company is set your price and production according to MR = MC principles, which shall not include fixed costs.
QUIZ: Multiple Choice
1. If a company's marginal revenue exceeds its marginal cost, non-profit maximum standards required to sign (a) increasing production in both perfect and imperfect competition, (2) to increase production in the perfect, but not necessarily in competition imperfecta, (3) increase production in the imperfect but not necessarily in perfect competition, (4) decline in production, both in perfect competition and imperfect, (5) increase in prices, not output, both perfect and imperfect competition.
2. Whenever a curve now demand is horizontal or perfectly elastic, then (1) the company can not operate in conditions of perfect competition, (2) the maximization rule benefits of MRI-as-a-MC does not apply, (3) price and marginal revenue must be yourself, and (4) price and marginal cost should be yourself, and (5) none of the above is necessarily correct.
3. A basic difference between the factory in perfect (or pure) competition and monopoly of the company, according with economic analysis, is as follows: (1) perfect competitor can sell everything you could want in a certain price, while the monopolist must lower the price whenever you want to increase the amount of sales by a significant amount;
(2) the monopolist can always charge a price that brings an important benefit while the perfect competitor can never get the benefit, (3) the elasticity of demand facing the monopolist is a figure higher than the elasticity of demand facing perfect competition, (4) the monopolist seeks to maximize profits, whereas the rule of perfect competition is match the price and average cost, (5) None of the above.
4. "Oligopoly" means (a) as well as imperfect competition, (2) a situation in which the number of competing is great but the products differ somewhat, (3) a situation in which the number of competing firms is small;
(4) the particular condition of imperfect competition, which just retired from monopoly, regardless of the number of companies or product type: (5) none of these.
5. When a monopoly firm seeking to maximize their benefits has reached its "equilibrium position", then (1) Price must be less than marginal cost, (2) The price must equal marginal cost, (3) which has higher price than marginal cost, (4) The price may be lower or equal marginal cost, but not above it; (5) None of the above is necessarily correct, since the balance does not require any particular relationship between the price and marginal cost.
6. To explain why imperfect competition is much more common than perfect competition, the text provides considerable emphasis on the following: (1) the fact that marginal revenue is less than the price, (2) the tendency of the marginal costs continue to decline in levels produced substantial production, (() the willingness of firms try to maximize the benefits they can derive from sales, (4) the tendency of the marginal costs up after a particular level of output produced has been reached (5) the fact that large companies now tend to produce many different products, therefore smaller companies tighten their markets.
7. Among the five states later, one has to be false in relation to any company operating under conditions of imperfect competition. What? (1) The number of competing vendors offer similar (although differentiated) products can be great. (2) Other companies may sell products
which are identical or almost identical with the product of this society. (3) The number of competing vendors offer similar (although differentiated) products may be small. (4) firm's marginal revenue is less than the price you get. (5) The demand curve facing the firm may be perfectly horizontal.
8. At the production level for a company in which the marginal cost had risen to equal the price would be (1) a production level that maximizes profits, both pure (or perfect) competition and imperfect competition, (2) an output level that maximizes profits in a pure (or perfect) competition but not imperfect competition, (3) non- a production level that maximizes profits, whether perfect or imperfect competition, (4) an output level that maximizes profits under imperfect competition but not in pure (or perfect) competition, (5) definitely a production level that maximizes the benefits of imperfect competition, but that may or except in the most pure (or perfect) competition.
9. A target = "_blank" company> under conditions of imperfect competition, which is in an output level where marginal cost has risen to equality with the price, and wants to maximize its profit, due to (1) increase their production, (2) change (increase or decrease) its price, but not its exit (3) to maintain both price and output at current levels, (4) increase their price, (5) may do any of the foregoing, the information provided is insufficient to count.
10. The essence of the rule to maximize the benefits listed in the section of text is that a company must set its price, or production, namely: to establish his (1) prices to a level at which the excess of the minimum possible average cost is at its maximum, (2) production at a level where additional production costs resulting from the last unit produced is equal to the additional income introduced by that last unit, (3) the highest price the traffic will bear, (4) prices at a level just equal to marginal cost (assuming that the marginal cost would increase with increased production), (5) output to a level where average cost is at a minimum.
11. A company would designated as a monopoly, according to the conventional definition used by economists, in any situation in which (a) The marginal revenue of the company higher than the price charged to all levels of production (other than the first unit sold), (2) of the firm marginal income is less than the price charged to all levels of production (other than the first unit sold), (3) the company has at least some degree of control over the price it can charge, (4) the benefits by the company. Significantly exceeds the competitive rate of return, after the proper allocation has been made for risk taking, (5) Is not another company from selling a close substitute for the products of this company.
12. The marginal revenue (MR) associated with any given point on the demand curve a firm will be related to the elasticity of demand at that point (with respect to price) as follows:
(1) When demand is inelastic, MR will be negative in value;
(2) when demand is elastic, MR will be negative in value;
(3) when demand is inelastic, the RM will be zero in value, (4)
