Condition for Producer Equilibrium

The producer equilibrium is a situation where a firm is maximizing its profits by producing a level of output where marginal cost (MC) is equal to marginal revenue (MR). In other words, the producer equilibrium is reached when a firm is producing at the point where it is making the highest possible economic profit.

The condition for producer equilibrium is as follows:

MC = MR

Explanation

Marginal cost (MC) is the additional cost of producing one more unit of output. Marginal revenue (MR) is the additional revenue earned by selling one more unit of output. In perfect competition, a firm is a price taker, meaning it cannot influence the market price of the product it sells. Therefore, the price of the product remains constant for the firm.

In perfect competition, the firm's marginal revenue (MR) is equal to the price of the product. Therefore, the condition for producer equilibrium can be rephrased as:

MC = P

where P is the price of the product.

If a firm produces at a level where MC is less than MR, it means that the firm can increase its profits by producing more units of output. Similarly, if a firm produces at a level where MC is greater than MR, it means that the firm can increase its profits by producing fewer units of output. So, the producer equilibrium is reached only when MC is equal to MR, where the firm is producing the level of output that maximizes its profits.

Conclusion

The condition for producer equilibrium is MC = MR, where a firm is producing the level of output that maximizes its profits. In perfect competition, where a firm is a price taker, the condition can be rephrased as MC = P.

Other name by which average revenue curve known:
  • a)
    Indifference curve
  • b)
    Profit curve
  • c)
    Average cost curve
  • d)
    Demand curve
Correct answer is option 'D'. Can you explain this answer?

Aryan Khanna answered
Average revenue curve is often called the demand curve due to its representation of the product's demand in the market. Each point on the curve represents the price of the product in the market. Price determines the demand for a product, hence Average revenue curve is also demand curve.
Assuming it is a perfect competitive market.

In perfect competition, since the firm is a price taker, the ________ curve is straight line
  • a)
    Total cost
  • b)
    Marginal cost
  • c)
    Total revenue
  • d)
    Marginal revenue
Correct answer is option 'D'. Can you explain this answer?

Aryan Khanna answered
Marginal revenue is the extra revenue generated when a perfectly competitive firm sells one more unit of output. The marginal revenue received by a firm is the change in total revenue divided by the change in quantity.
Perfect competition is a market structure with a large number of small firms, each selling identical goods. Perfectly competitive firms have perfect knowledge and perfect mobility into and out of the market. These conditions mean perfectly competitive firms are price takers, they have no market control and receive the going market price for all output sold.
Since they are the price takers and have no control over price but just the production, so even if they increase their quantity of production, still the price will remain constant and so does the marginal revenue.

In the long run the market price of a commodity is equal to its minimum average cost of production under the___________?
  • a)
    Monopolist competition
  • b)
    Perfect competition
  • c)
    Oligopoly
  • d)
    Monopoly
Correct answer is option 'B'. Can you explain this answer?

Kiran Mehta answered
Perfect competition is an industry structure in which there are many firms producing homogeneous products.
None of the firms are large enough to influence the industry. In the long-run, companies that are engaged in a perfectly competitive market earn zero economic profits.
The long-run equilibrium point for a perfectly competitive market occurs where the demand curve (price) intersects the marginal cost (MC) curve and the minimum point of the average cost (AC) curve.
Since they are the price takers and the price remains constant so does the AC of production.

When ___________, the firms are earning just normal profit:
  • a)
    AC=AR
  • b)
    MC=AC
  • c)
    AR=MR
  • d)
    MC=MR
Correct answer is option 'A'. Can you explain this answer?

Vikas Kapoor answered
AC = AR means the firm’s cost and revenue are equal which means the firm does not earn any profit or no loss, which means the firm is earning normal profit.

Which of the following is the condition for equilibrium of a firm?
  • a)
    MC curve must cut MR curve from above
  • b)
    MR = MC
  • c)
    None of above
  • d)
    Both of these
Correct answer is option 'B'. Can you explain this answer?

Equilibrium of a Firm:

Equilibrium of a firm refers to a situation where the firm is earning maximum profits or where there is no incentive to change the level of output. In other words, the firm is producing the level of output where its marginal cost equals its marginal revenue.

Condition for Equilibrium:

The condition for equilibrium of a firm is that its marginal revenue (MR) should be equal to its marginal cost (MC). This condition can be explained as follows:

- Marginal Revenue (MR): Marginal revenue is the additional revenue earned by the firm by selling one additional unit of output. It is also the slope of the total revenue curve.

- Marginal Cost (MC): Marginal cost is the additional cost incurred by the firm by producing one additional unit of output. It is also the slope of the total cost curve.

When the firm produces one additional unit of output, it incurs an additional cost (MC) and earns an additional revenue (MR). If MR is greater than MC, the firm should produce more output as it will earn more revenue than the cost incurred. On the other hand, if MC is greater than MR, the firm should produce less output as it will incur more cost than the revenue earned. Therefore, the firm should produce the level of output where MR equals MC, as at this level of output, the firm is earning maximum profits.

Conclusion:

Hence, the condition for equilibrium of a firm is that MR should be equal to MC. If the firm produces any other level of output, it will not be in equilibrium, as it will either earn less profit or incur losses.

What are the conditions for the long run equilibrium of the competitive firm?
  • a)
    SMC=SAC=LMC
  • b)
    P=MR
  • c)
    LMC=LAC=P
  • d)
    All of the above
Correct answer is option 'C'. Can you explain this answer?

Anjana Desai answered
Conditions for Long Run Equilibrium of Competitive Firm

In a perfectly competitive market, there are certain conditions that must be met for a firm to achieve long-run equilibrium. These conditions are as follows:

LMC = LAC = P

In the long run, a firm in a perfectly competitive market will produce at the point where its long-run marginal cost (LMC) is equal to its long-run average cost (LAC). At this point, the firm is producing at the minimum efficient scale, which means that it is producing at the lowest possible cost.

At the same time, the price of the good or service that the firm is selling (P) must be equal to its long-run marginal cost (LMC) and its long-run average cost (LAC). This condition ensures that the firm is earning zero economic profit in the long run.

Implications of these Conditions

When a firm is in long-run equilibrium, it is operating at maximum efficiency. It is producing at the lowest possible cost and selling its output at a price that is just enough to cover its costs. As a result, there is no incentive for new firms to enter the market, and existing firms have no reason to leave.

In this state of equilibrium, the market is perfectly competitive, with many firms producing the same good or service. Consumers benefit from the low prices that result from the firms' efficient production, and the firms themselves are able to earn a reasonable rate of return on their investments.

Conclusion

In conclusion, the conditions for long-run equilibrium of a competitive firm are that its long-run marginal cost (LMC) must be equal to its long-run average cost (LAC), and both these costs must be equal to the price (P) of the good or service. When these conditions are met, the firm is operating at maximum efficiency and the market is perfectly competitive.

Before producer’s equilibrium when MR>MC, the firm earns only
  • a)
    Normal Profit
  • b)
    Normal loss
  • c)
    Abnormal loss
  • d)
    Abnormal profit
Correct answer is option 'D'. Can you explain this answer?

Vikas Kapoor answered
If a firm makes more than normal profit it is called super-normal profit. Supernormal profit is also called economic profit, and abnormal profit, and is earned when total revenue is greater than the total costs. 
Total profits = total revenue (TR) – total costs (TC)
Abnormal Profit = MR > MC

For maximum profit, the condition is:
  • a)
    MC=AC
  • b)
    MR=MC
  • c)
    AR=AC
  • d)
    MR=AR
Correct answer is option 'B'. Can you explain this answer?

Rajat Patel answered
This strategy is based on the fact that the total profit reaches its maximum point where marginal revenue equals marginal profit. This is the case because the firm will continue to produce until marginal profit is equal to zero, and marginal profit equals the marginal revenue (MR) minus the marginal cost (MC).

Supernormal profit occur, when?
  • a)
    Total revenue is equal to variable cost
  • b)
    Average revenue is more than average cost
  • c)
    Average revenue is equal to average cost
  • d)
    Total revenue is equal to total cost
Correct answer is option 'B'. Can you explain this answer?

Poonam Reddy answered
Supernormal profit is defined as extra profit above that level of normal profit. Supernormal profit is also known as abnormal profit. Abnormal profit means there is an incentive for other firms to enter the industry.

The elasticity at a point on a straight line supply curve passing through the origin making an angle of 45°will be
  • a)
    4
  • b)
    2
  • c)
    3
  • d)
    1.0
Correct answer is option 'D'. Can you explain this answer?

Sahil Khanna answered
Degrees with the horizontal axis is equal to 1.

Explanation:

The elasticity of supply is defined as the percentage change in quantity supplied divided by the percentage change in price. Mathematically, it can be represented as:

Elasticity of Supply = (% Change in Quantity Supplied) / (% Change in Price)

For a linear supply curve passing through the origin, the slope of the curve represents the change in quantity supplied for a given change in price. This slope is constant along the curve, and equals the tangent of the angle made by the curve with the horizontal axis.

In this case, the angle is 45 degrees, which means the slope is 1. Therefore, for a given change in price, the quantity supplied changes by the same percentage. This implies that the elasticity of supply is 1, which means that supply is unit elastic at every point along the curve.

5. Resources for such a labor are perfectly mobile.
6. Firms can enter or exit the market without cost.

A rational consumer is a person who?
  • a)
    Has perfect knowledge of the market
  • b)
    Is not influenced by persuasive advertising
  • c)
    Behaves at all times, other things being equal, in a judicious manner
  • d)
    Knows the prices of goods in different market and buys the cheapest
Correct answer is option 'A'. Can you explain this answer?

Alok Verma answered
A rational consumer is considered to be that person who makes rational consumption decisions.
In other words, the consumer who makes his choices after considering all the other alternative goods (and services) available in the market is called a rational consumer.

Beyond producer’s equilibrium when MR<MC, the firm earns only
  • a)
    Abnormal profit
  • b)
    Normal loss
  • c)
    Abnormal loss
  • d)
    Normal Profit
Correct answer is option 'C'. Can you explain this answer?

Aravind Saha answered
Marginal Cost < Marginal Revenue means abnormal loss situation, where the total revenue of a business does not cover total cost incurred for the business, due to which the profits of the business are below normal limits.

While a seller under perfect competition equates price and MC to maximize profits a monopolist should equate?
  • a)
    MR and MC
  • b)
    AR and MR
  • c)
    AR and MC
  • d)
    TC and TR
Correct answer is option 'A'. Can you explain this answer?

Vikas Kapoor answered
In a monopolistic market, there is only one firm that produces a product. There is absolute product differentiation because there is no substitute.
The marginal cost of production is the change in the total cost that arises when there is a change in the quantity produced.
The marginal revenue is the change in the total revenue that arises when there is a change in the quantity produced a firm maximizes its total profit by equating marginal cost to marginal revenue and solving for the price of one product and the quantity it must produce.

The elasticity at a point on a straight line supply curve passing through the origin will be
  • a)
    3
  • b)
    1.0
  • c)
    4
  • d)
    2
Correct answer is option 'B'. Can you explain this answer?

Arun Yadav answered
Regardless of the gradient of the linear supply curve or its position on the supply curve, the PES of a linear supply curve that passes through the origin is always equal to 1. Therefore, if the supply curve originates with P=0 and Q=0, the elasticity will always be 1.
 
Formula-

A competitive firm in the short run incurs losses. The firm continues production, if?
  • a)
    P=AVC
  • b)
    P>AVC
  • c)
    P<AVC
  • d)
    P>=AVC
Correct answer is option 'D'. Can you explain this answer?

Om Desai answered
With loss minimization, price exceeds average variable cost but is less than average total cost at the quantity that equates marginal revenue and marginal cost. In this case, the firm incurs a smaller loss by producing some output than by not producing any output.

Naina Sharma answered
Perfect competition occurs when all companies sell identical products, market share does not influence price, companies are able to enter or exit without barrier, buyers have “perfect” or full information, and companies cannot determine prices. For example consider a farmers market where each vendor sells the same type of jam. There is little differentiation between each of their products, as they use the same recipe, and they each sell them at an equal price. At the same time, sellers are few and free to participate in the market without any barrier. Buyers, in this case, would be fully knowledgeable of the product's recipe, and any other information relevant to the good.

Globalisation is the rapid integration or interconnection between countries mostly on the economic plane. In other words Globalisation means integrating our economy with the world economy.Movement of people between countries increases due to globalisation. CORRECT OPTION IS (B).

Direction: In the following questions, a statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as:
Assertion (A): In monopolistic competition, there is a fierce competition between the firms in the market.
Reason (R): In monopolistic competition, there are a large number of sellers and buyers in the market.
  • a)
    Both Assertion (A) and Reason (R) are true, and Reason (R) is the correct explanation of the Assertion (A).
  • b)
    Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of the Assertion (A).
  • c)
    Assertion (A) is true, but Reason (R) is false.
  • d)
    Assertion (A) is false, but Reason (R) is true.
Correct answer is option 'B'. Can you explain this answer?

Explanation:

Assertion (A): In monopolistic competition, there is a fierce competition between the firms in the market.

Reason (R): In monopolistic competition, there are a large number of sellers and buyers in the market.

Correct Answer: Option B - Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of the Assertion (A).

Explanation:

Monopolistic Competition:
Monopolistic competition is a market structure where there are a large number of sellers who offer differentiated products. In this market structure, each firm has some control over the price of its product due to product differentiation, but there is still competition from other firms.

Explanation of Assertion (A):
In monopolistic competition, there is fierce competition between the firms in the market. This is because each firm tries to differentiate its product from competitors in order to attract customers. Firms engage in advertising, branding, and other marketing strategies to create a unique image for their products. This creates competition among the firms as they try to capture a larger market share.

Explanation of Reason (R):
In monopolistic competition, there are indeed a large number of sellers and buyers in the market. This market structure is characterized by having many firms, each producing a slightly different product. This variety of products gives consumers choices and allows them to switch between different brands. Similarly, there are many firms competing for the same set of customers, which leads to intense competition.

Explanation of Correct Answer:
Both Assertion (A) and Reason (R) are true. In monopolistic competition, there is indeed fierce competition between firms, and there are a large number of sellers and buyers in the market. However, Reason (R) is not the correct explanation of the Assertion (A). The reason does not directly explain why there is fierce competition in monopolistic competition. The presence of a large number of sellers and buyers in the market is a characteristic of the market structure, but it does not directly explain the intensity of competition among the firms. The intense competition arises due to firms' efforts to differentiate their products and attract customers.

At producer’s equilibrium when MR=MC, the firm earns only
  • a)
    Abnormal loss
  • b)
    Abnormal profit
  • c)
    Normal Profit
  • d)
    Normal loss
Correct answer is option 'C'. Can you explain this answer?

Anjali Sharma answered
Producer’s equilibrium refers to the state in which a producer earns his maximum profit or minimises its losses. According to the MR-MC approach, the producer is at equilibrium when the Marginal Revenue (MR) is equal to the Marginal Cost (MC), and the Marginal Cost curve must cut the Marginal Revenue curve from below.
Two conditions under this approach are:
(i) MR = MC
(ii) MC curve should cut the MR curve from below, or MC should be rising.

Marginal revenue in any competitive situation is?
  • a)
    Trn-Pn-1
  • b)
    TRn-TRn-1
  • c)
    TRn/Qn-1
  • d)
    None of above
Correct answer is option 'B'. Can you explain this answer?

Neha Choudhury answered
Marginal revenue (MR) can be defined as additional revenue gained from the additional unit of output. Marginal revenue is the change in total revenue which results from the sale of one more or one less unit of output.
Formula:
Total revenue=TR
Total Unit = n
Total Unit less one unit = n-1
MR= TRn-TRn-1.

Direction: In the following questions, a statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as:

    Assertion (A) is false, but Reason (R) is true.
Correct answer is option 'B'. Can you explain this answer?

Maitri Sharma answered
Assertion (A): There is no restriction on the entry and exit of the firms in the perfect competitive market.


Reason (R): The perfect competition market is characterized by the sellers being a price taker and not a price maker.

The correct answer is option 'B' - Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of the Assertion (A).

Explanation:
Perfect competition is a market structure where there are many buyers and sellers, and no individual firm has control over the market price. In this type of market, there are no restrictions on the entry and exit of firms. Let's examine each statement in detail:

Assertion (A): There is no restriction on the entry and exit of the firms in the perfect competitive market.
In a perfectly competitive market, new firms are free to enter the market if they believe they can earn profits. Similarly, existing firms are free to exit the market if they are incurring losses. There are no legal or regulatory barriers that prevent firms from entering or exiting the market. This is because perfect competition promotes competition and allows for efficient allocation of resources.

Reason (R): The perfect competition market is characterized by the sellers being a price taker and not a price maker.
In a perfectly competitive market, each firm is a price taker, meaning they have no control over the market price. The market price is determined by the overall supply and demand in the market. Individual firms have to accept the prevailing market price and adjust their quantity of production accordingly. They cannot influence the market price by changing their output. This is because there are many buyers and sellers in the market, and no individual firm has enough market power to affect the market price.

Explanation of the Correct Answer:
Both Assertion (A) and Reason (R) are true. In a perfectly competitive market, there are no restrictions on the entry and exit of firms, and sellers are price takers. However, Reason (R) does not provide a direct explanation for Assertion (A). The fact that sellers are price takers does not necessarily imply that there are no restrictions on entry and exit. Therefore, option 'B' is the correct answer.

Direction: In the following questions, a statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as:
Assertion (A): Reliance has a monopoly in the sector of telecommunication with its Jio in India.
Reason (R): Monopoly is characterised when there is only one seller in the market and the firm is a price maker.
  • a)
    Both Assertion (A) and Reason (R) are true, and Reason (R) is the correct explanation of the Assertion (A).
  • b)
    Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of the Assertion (A).
  • c)
    Assertion (A) is true, but Reason (R) is false.
  • d)
    Assertion (A) is false, but Reason (R) is true.
Correct answer is option 'D'. Can you explain this answer?

Understanding the Assertion and Reason
The statement involves analyzing the relationship between the assertion about Reliance's monopoly in telecommunications and the reasoning behind the definition of monopoly.
Assertion (A): Reliance has a monopoly in the sector of telecommunications with its Jio in India.
Reason (R): Monopoly is characterized when there is only one seller in the market, and the firm is a price maker.
Analysis of Assertion (A)
- False Assertion:
- While Reliance Jio is a significant player in the Indian telecommunications market, it does not hold a monopoly.
- The Indian telecom sector has multiple competitors, including Airtel, Vodafone-Idea, and others.
- Therefore, the market is characterized by competition rather than a single seller.
Analysis of Reason (R)
- True Reason:
- The definition provided for monopoly is accurate.
- A monopoly exists when a single seller controls the entire market and can set prices without competition.
Conclusion
- Given that Assertion (A) is false and Reason (R) is true, the correct choice is:
Option D: Assertion (A) is false, but Reason (R) is true.
This analysis clarifies that while the concept of monopoly is correctly defined, the statement regarding Reliance Jio's position in the telecommunications market is incorrect, as it faces substantial competition.

Direction: Read the following passage and answer the questions that follows:
A price floor is the lowest legal price that can be paid in a market for goods and services, labour, or financial capital. Perhaps the best-known example of a price floor is the minimum wage, which is based on the normative view that someone working full time ought to be able to afford a basic standard of living. The federal minimum wage at the end of 2014 was $7.25 per hour, which yields an income for a single person slightly higher than the poverty line. As the cost of living rises over time, Congress periodically raises the federal minimum wage.
Price floors are sometimes called price supports because they support a price by preventing it from falling below a certain level. Around the world, many countries have passed laws to create agricultural price supports. Farm prices, and thus farm incomes, fluctuate—sometimes widely. So even if, on average, farm incomes are adequate, some years they can be quite low. The purpose of price supports is to prevent these swings.
The most common way price supports work is that the government enters the market and buys up the product, adding to demand to keep prices higher than they otherwise would be.
Q. Read the following statements–Assertion (A) and Reason (R).
Assertion (A): Price floor is also known as price support.
Reason (R): Price floor supports a price from falling the certain level
Select the correct alternative from the following:
  • a)
    Both Assertion (A) and Reason ( R) are true.
  • b)
    Both Assertion (A) and Reason (R) are false.
Correct answer is option 'A'. Can you explain this answer?

Anu Basu answered
Understanding Price Floor and Price Support
The assertion and reason presented in the passage are both true, which is why option 'A' is the correct answer. Here’s a detailed explanation:
Assertion (A): Price Floor is also known as Price Support
- Price floors, such as the minimum wage, are designed to maintain a minimum price level in various markets.
- They prevent prices from dropping below a certain threshold, which is essential for ensuring that producers, such as farmers, receive fair compensation for their goods and services.
- This concept is often referred to as "price support" because it supports the price level, protecting the income of those affected.
Reason (R): Price Floor Supports a Price from Falling Below a Certain Level
- The purpose of a price floor is to prevent prices from falling too low, which can lead to negative economic consequences like reduced income for workers or farmers.
- Governments implement price floors to stabilize market prices and provide a safety net during periods of economic downturns or agricultural fluctuations.
- For example, in agriculture, governments may intervene by purchasing surplus products to maintain higher prices, thus supporting farmers' incomes.
Conclusion
- Since both the assertion and reason accurately reflect the characteristics and functions of price floors, they align with the definition provided in the passage.
- Therefore, both statements being true supports the conclusion that option 'A' is correct.
This understanding helps clarify the role of price floors in economic policy and market regulation.

Arun Yadav answered
A. Price Floor: Price floor is a situation when the price charged is more than or less than the equilibrium price determined by market forces of demand and supply. By observation, it has been found that lower price floors are ineffective. Price floor leads to a lesser number of workers than in case of equilibrium wage.
B. Price Ceiling: A price ceiling is the mandated maximum amount a seller is allowed to charge for a product or service. Usually set by law, price ceilings are typically applied to staples such as food and energy products when such goods become unaffordable to regular consumers.
C. Price Floor: Price floor is a situation when the price charged is more than or less than the equilibrium price determined by market forces of demand and supply. By observation, it has been found that lower price floors are ineffective. Price floor leads to a lesser number of workers than in case of equilibrium wage.
D. Price Ceiling: A price ceiling is the mandated maximum amount a seller is allowed to charge for a product or service. Usually set by law, price ceilings are typically applied to staples such as food and energy products when such goods become unaffordable to regular consumers.

A. Effect on supply, in case of perfectly Elastic Demand: If supply is perfectly elastic, it means that any change in price will result in an infinite amount of change in quantity.
B. Effect on demand, in case of Perfectly Inelastic Supply: When demand is perfectly inelastic, quantity demanded for a good does not change in response to a change in price. Finally, demand is said to be perfectly elastic when the PED coefficient is equal to infinity. When demand is perfectly elastic, buyers will only buy at one price and no other.
C. Effect on demand, in case of Perfectly Elastic Supply: The PES for perfectly elastic supply is infinite, where the quantity supplied is unlimited at a given price, but no quantity can be supplied at any other price.
D. Effect on supply, in case of Perfectly Elastic Demand: If supply is perfectly elastic, it means that any change in price will result in an infinite amount of change in quantity.

  • Monopoly: A monopoly is a firm who is the sole seller of its product, and where there are no close substitutes. An unregulated monopoly has market power and can influence prices. Examples: Microsoft and Windows, DeBeers and diamonds, your local natural gas company.
  • Perfect Competition: Perfect competition is an ideal type of market structure where all producers and consumers have full and symmetric information, no transaction costs, where there are a large number of producers and consumers competing with one another. Perfect competition is theoretically the opposite of a monopolistic market. Examples of this perfect market structure are: A large number of buyers. A large number of sellers. Every participant is a price taker, not having the ability to influence market prices.
  • Monopolistic competition: Monopolistic competitive markets have highly differentiated products; have many firms providing the good or service; firms can freely enter and exits in the long-run; firms can make decisions independently; there is some degree of market power; and buyers and sellers have imperfect information.

A. Features of Monopoly Market: A monopoly market is characterized by the profit maximizer, price maker, high barriers to entry, single seller, and price discrimination. Monopoly characteristics include profit maximizer, price maker, high barriers to entry, single seller, and price discrimination.
B. Advantages of Monopoly Market: The advantage of monopolies is the assurance of a consistent supply of a commodity that is too expensive to provide in a competitive market.
C. Limitation of Monopoly Market: A monopoly market is characterized by the profit maximizer, price maker, high barriers to entry, single seller, and price discrimination. Monopoly characteristics include profit maximizer, price maker, high barriers to entry, single seller, and price discrimination.
D. Feature of Perfect Competition: A perfectly competitive market is characterized by many buyers and sellers, undifferentiated products, no transaction costs, no barriers to entry and exit, and perfect information about the price of a good. The total revenue for a firm in a perfectly competitive market is the product of price and quantity (TR = P * Q).

MR curve=AR=Demand curve is a feature of which kind of market?
  • a)
    Perfect competition
  • b)
    Oligopoly
  • c)
    Monopolistic competition
  • d)
    Monopoly
Correct answer is option 'A'. Can you explain this answer?

MR curve=AR=Demand curve is a feature of which kind of market?
The feature of MR curve=AR=Demand curve is characteristic of a perfect competition market. In a perfect competition market, there are numerous buyers and sellers of homogeneous products. Here is a detailed explanation:
1. Perfect competition:
- Perfect competition is a market structure where there are many buyers and sellers.
- The products sold in this market are identical or homogeneous, meaning they are indistinguishable from each other.
- There is free entry and exit of firms in the market, allowing for easy competition.
- The information is perfect, and all participants have full knowledge of prices and market conditions.
- In perfect competition, firms are price takers, meaning they cannot influence the market price.
- The demand curve faced by a firm in perfect competition is perfectly elastic, i.e., horizontal.
- Marginal revenue (MR) is equal to average revenue (AR), which is equal to the demand curve.
2. MR curve=AR=Demand curve:
- In perfect competition, since the firm is a price taker, it can only sell its output at the prevailing market price.
- The demand curve faced by the firm is perfectly elastic, meaning any change in quantity will not affect the price.
- Consequently, the average revenue (AR) curve, which represents the price at which the firm sells its output, is a horizontal line.
- Since the firm can sell additional units only at the prevailing market price, the marginal revenue (MR) curve is also horizontal and coincides with the AR curve.
- Therefore, in perfect competition, the MR curve, AR curve, and demand curve are all the same.
Conclusion:
- The feature of MR curve=AR=Demand curve is unique to perfect competition.
- In other market structures like oligopoly, monopolistic competition, and monopoly, the MR curve, AR curve, and demand curve are not equal.
- Thus, the correct answer to the question is A: Perfect competition.

Answer:

Market situation: Perfect competition

Explanation:

1. Characteristics of perfect competition:


  • A large number of buyers and sellers

  • Homogeneous products

  • Perfect knowledge and information

  • No barriers to entry or exit

  • Price takers - firms have no control over the price


2. Demand curve in perfect competition:


  • Perfectly competitive firms face a perfectly elastic demand curve.

  • The demand curve is horizontal or parallel to the X-axis because the firm can sell as much as it wants at the market price.

  • The price is determined by the market forces of supply and demand, and individual firms have no influence on it.

  • If a firm tries to charge a higher price, buyers will shift their demand to other firms in the market.

  • If a firm tries to charge a lower price, it will not be able to sell any additional quantity because buyers can already purchase as much as they want at the market price.


3. Linear demand curve:


  • A linear demand curve is a straight line on a graph, indicating a constant rate of change in quantity demanded for each unit change in price.

  • In perfect competition, the demand curve is linear because the price remains constant regardless of the quantity demanded by the firm.

  • As the firm increases its output, it can sell all the additional units at the market price.


Therefore, in a market situation of perfect competition, the demand curve is linear and parallel to the X-axis.

Direction: Read the following passage and answer the questions that follows:
More specifically, a price ceiling (in other words, a maximum price) is put into effect when the government believes the price is too high and sets a maximum price that producers can charge; this price must lie below the equilibrium price in order for the price ceiling to have an effect.
The price ceiling is usually instituted via law and is typically applied to necessary goods like food, rent, and energy sources in order to ensure that everyone has access to them.
Benefits and Downsides:
Price ceilings are beneficial to society, and are often necessary, in that they make sure that essential goods are financially accessible to the average person, at least in the short run. By lowering costs, price ceilings also have the beneficial effect of helping to stimulate demand, which can contribute to the health of an economy.
However, there can also be downsides to price ceilings. While they stimulate demand, price ceilings can also cause shortages. Where the ceiling is set, there is more demand than at the equilibrium price. This means that the amount of the good or service supplied is less than the quantity demanded.
For example, in agriculture, medicine, and education, many governments set maximum prices to make the needed goods or services more affordable. Producers may respond to such an economic situation by rationing supplies, decreasing production levels or lowering the quality of production, making the consumer pay extra for otherwise free elements of the good (features, options, etc.), and more.
Q. How do the producers respond to the situation of price ceiling?
  • a)
    Rationing supplies
  • b)
    Decreasing production level
  • c)
    Lowering the quality of production
  • d)
    All of the above
Correct answer is option 'D'. Can you explain this answer?

Kiran Mehta answered
A price ceiling is a government- or group-imposed price control, or limit, on how high a price is charged for a product, commodity, or service. Governments use price ceilings ostensibly to protect consumers from conditions that could make commodities prohibitively expensive.

Arun Yadav answered
A. Demand Curve of Perfect Competition: The market demand curve is downward-sloping. The market demand curve slopes downward, while the perfectly competitive firm's demand curve is a horizontal line equal to the equilibrium price of the entire market. The horizontal demand curve indicates that the elasticity of demand for the good is perfectly elastic.
B. Demand Curve of Monopoly: Monopolies have downward sloping demand curves and downward sloping marginal revenue curves that have the same y-intercept as demand but which are twice as steep. The shape of the curves shows that marginal revenue will always be below demand.
C. Demand Curve of Monopolistic Competition: The demand curve for an individual firm is downward sloping in monopolistic competition, in contrast to perfect competition where the firm's individual demand curve is perfectly elastic. This is due to the fact that firms have market power: they can raise prices without losing all of their customers.
D. Demand Curve of Oligopoly: In an oligopolistic market, the kinked demand curve hypothesis states that the firm faces a demand curve with a kink at the prevailing price level. The curve is more elastic above the kink and less elastic below it. This means that the response to a price increase is less than the response to a price decrease.

Kiran Mehta answered
A. Product differentiation: In a perfectly competitive market products are perfect substitutes for each other. But in monopolistically competitive markets the products are highly differentiated. In fact, firms work hard to emphasize the non-price related differences between their products and their competitors'.
B. Firms sell homogeneous products: Pure or perfect competition is a theoretical market structure in which the following criteria are met: All firms sell an identical product (the product is a "commodity" or "homogeneous"). All firms are price takers (they cannot influence the market price of their product). Market share has no influence on prices.
C. Optimal allocation of resources in the long run: In the long run in a perfectly competitive market—because of the process of entry and exit the price in the market is equal to the minimum of the long-run average cost curve. ... In other words, goods are being produced and sold at the lowest possible average cost.
D. Firms are price makers: Price takers are found in perfectly competitive markets. Price makers are able to influence the market price and enjoy pricing power. Price makers are found in imperfectly competitive markets such as a monopoly. In a perfectly competitive market, which comprises or oligopoly market.
