Relationship between price and revenue of the perfect competitive firm

Introduction

A market refers to a device or arrangement y which customers and sellers of the commodity have the ability to contact each other for having financial exchange and are able to strike a deal about the price and the number to be bought and sold. Essentially, there are 4 types of market structures:

Perfect Competition

Monopolistic Market

Monopoly

Oligopoly

All of the firms have one thing in common - a definite romantic relationship between price and revenue. In this essay, we shall look at the marriage between price and income in a correctly competitive market composition.

Perfectly Competitive Market

Before we go through the romantic relationship between price and earnings, we must understand what a properly competitive market is.

Perfect competition is market structure in which there are a large number of suppliers (businesses) creating a homogeneous product so that no individual firm can effect the price of the commodity. In this kind of market, the purchase price is determined by the industry. A flawlessly competitive firm is undoubtedly a small part of the total industry where it operates that this cannot affect the price of the product. Which means that the company under perfect competition is assumed to be a price - manufacturer rather than price - taker.

Features of Perfect Competition

A market to be flawlessly competitive will need to have the next features:

Large volume of buyers and retailers - this means that under perfect competition, a firm produces such a little part of the total market result that a change in its outcome will have no noticeable influence on market resource and, hence, the price of the product.

Homogeneous product - All companies under perfect competition produce homogeneous or properly standardised products. Since there is absolutely no room for product differentiation, there is absolutely no room for price differentiation. The implication of this characteristic is a standard price will rule throughout the marketplace.

Freedom of access and exit - this means that new organizations are free to enter into the industry and existing companies are free to leave the industry if indeed they desire so. This implies that firms under perfect competition are just capable of getting normal profits over time.

Perfect flexibility of resources - this quality implies that resources or factors of creation can enter in or quit a firm or industry at will. In addition, it implies that resources are able to switch over from one use to some other without any restriction.

Perfect knowledge - consumers, firms and resource owners under perfect competition have perfect knowledge about the marketplace. This attribute would ensure that price differences are quickly removed and an individual price for the product would finally prevail throughout the marketplace.

Absence if transportation costs - this feature implies that there is absolutely no cost of transportation. This is to keep up uniform price throughout the marketplace.

Price and Earnings in Perfect Competition

Perfect competition signifies a market framework where all companies are exactly the same - and this includes to process of production. Here, there is no room for just one individual firm to increase exponentially. The price tag on the commodity is strictly the same in all companies under perfect competition. Just as, revenue also does not change as there is certainly neither product differentiation nor price differentiation. Theoretically, the income of all firms will be the same. Here, we will focus on Average Revenue (AR) and Marginal Revenue (MR).

Relationship Between AR, MR and Price (P)

Average Revenue is defined as the revenue gained per device of the product sold. Marginal earnings is defined as the addition to total earnings which results from the deal of 1 additional product of output. There's a clear relationship between AR, MR, and Price. Let us observe how they respond in a Beautifully Competitive market structure.

Let us take the example in table and in the graph above.

Since a firm under perfect competition is not needed to reduce the price selling more products of outcome, AR is regular at all levels of output. It is because AR is equivalent to price and price under perfect competition is constant. It really is clear from the table above that AR is the same by any means levels of end result. Graphically, AR curve is a horizontal in a straight line line at the level of ruling price OP in the graph below.

Since every additional product can be sold at the same price, it practices that the firm's MR resulting from a rise in sales by one product is frequent and equal to the price of the product. Quite simply, if the purchase price or AR remains the same when more products of a product are sold, MR will be equal to AR and it'll be constant. Through the table above, it is clear that MR is Rs. 15 at all levels of result and is add up to AR and/ or price. Thus, in the graph below, MR and AR curves are shown to coincide at the amount of price OP, exhibiting that AR = MR in any way levels of output.

Examples of Perfect Competition

Although there is absolutely no 'real life' example of Perfect Competition, there are a few that come close. Take agricultural products for illustration. You can find agricultural products like Ponni Grain and Samba Wheat for which the marketplace is near perfect. There is very little differentiation between the products grown in a single place and cultivated in another. Price and income could be more or less the same all around. But, there are factors which ensure that a situation like perfect competition will never appear. One major factor is that you will see a transportation cost. This factor is enough to ensure that the marketplace is imperfect. Another factor is the fact the grade of the product produced can vary greatly from location to place. Hence, a predicament of perfect competition can't ever exist. We are able to only achieve a near perfectly competitive market framework.

Conclusion

As mentioned above, in perfect competition, price and average revenue and marginal revenue are equivalent. But there are no illustrations that we can identify as correctly competitive in true to life. Perfect competition is a theory of market structure that is useful to comprehend other principles of economics. What we normally experience is the fact that as the number of units of productivity is increased, price decrease causing average income and marginal income to decrease as well.
