Overview of Economics Example

Economics is a science that research human behaviour in several conditions and derives numerous inference that can be helpful for the enterprise. Economics can also be thought-about as the science of selection making which can help the individual in choosing the varied elements based mostly on their requirement. The essential assumption in all of the financial theorems or rule is that human being is rational and shall be considering in terms of civilised society.

There is a numerous idea in Economics, nevertheless, we now have tried to explain the under mentioned most necessary concept of economics.

Examples of Economics

Using some basic or real-world examples, economics may be higher understood:-

Economics Example #1 – Shopper Surplus

Shopper Surplus is the power of the buyer to pay worth for any commodity as in comparison with the precise worth prevailing out there.

As per Prof. Alfred Marshall,

“the surplus price which a person is willing to pay rather than stay without the thing, over that what he actually pays, is the measurement of a surplus of utility– known as consumer’s surplus.”

  • Shopper’s surplus = Worth ready to pay (-) Worth Truly Paid
  • Shopper’s surplus = Complete utility – ( P * Q)
  • Shopper’s surplus = Complete utility – Complete expenditure.

Let’s perceive this idea with the assistance of an example:


There’s a Product A, whose marginal utility and costs per unit are as given under:

Consumer Surplus -1

From this calculate Shopper’s surplus and plot the same on a curve with proper description.


Consumer Surplus -1.1

From the table, it’s clear that for six models the buyer was prepared to pay 210 however he needed to pay 60. Subsequently shopper’s surplus = 210 – 60 = 150

Shopper Surplus Curve

Consumer Surplus Curve -1.3

Within the determine, we now have the shaded zone exhibiting shopper’s surplus.

The Usefulness of Shopper’s Surplus

(i) It helps to make economic comparisons concerning the individuals’s welfare between two places or nations.

(ii) The concept is beneficial in understanding the pricing policies of a discriminating monopolist & wiping out the excess by totally different levels of discrimination.

(iii) It helps in evaluating the economic impact of a tax on a commodity.

(iv) It helps to measure the advantages of worldwide commerce.

Economics Example #2 – Brief-Run Costs

In the brief run, many elements of manufacturing won’t diversified, and subsequently, stay fastened. The fee that a firm incurs to irrespective of production is termed complete fastened value (TFC). Fastened value will remain the identical and it’ll not change at any degree of output. Within the brief run only output might be controlled, therefore value that modifications based mostly on the output are termed as Variable value. (TVC). Adding the fastened and the variable costs, we get the entire value (TC) of a agency


  • TC = TVC + TFC
  • SAC = TC/q
  • AVC = TVC/q
  • AFC= TFC/q
  • SMC= Change in complete value/ change in output = ΔTC/ Δq

As a way to improve the manufacturing of output, the firm needs to employ more of the variable inputs. Consequently, the whole variable value and the whole value will improve. Thus, With an increase in output, the variable value will improve nevertheless fastened value will stay the identical.


ABC Ltd is planning to set up the manufacturing unit. It is planning to fabricate the commodity. The detailed schedule of value based mostly on output is as given under:

    Short Run Costs -2.1

Calculate Common fastened value (AFC), Average Variable value (AVC), Brief time period average value(SAC) and brief term marginal value (SMC)

Answer :

    Short Run Costs -2.2

The above calculation is made based mostly on under formulae:

  1. Complete value= Complete Fastened Value + Complete Variable Value
  2. Common Fastened Value = Complete Fastened Value / Output
  3. Average Variable value = Complete Variable value / Output
  4. Brief-run Average value = Complete Value / Output
  5. Brief-run marginal value = Complete value at the output at Q1 – Complete value at the output at Q0


Economics Example-2.3

Economics Example -2.4

Within the above diagram we will observe that:

  • Fastened value remains similar irrespective of output
  • Variable value increases at a lowered fee
  • The full value will start with Fastened value and can improve in parallel to variable value
  • AFC curve is, actually, an oblong hyperbola. AFC is the ratio of TFC to q. TFC is constant. Subsequently, as q increases, AFC decreases. When the output could be very near zero, AFC is arbitrarily giant, and as output moves in the direction of infinity, AFC strikes in the direction of zero.


  1. Marginal value is the increase in TVC because of improve in manufacturing of one additional unit of output
  2. For any degree of output, the sum of marginal prices up to that degree provides us the full variable value at that degree.
  3. Average variable value at some degree of output is, subsequently, the typical of all marginal costs up to that degree

Economics Example three – Regulation of Diminishing Marginal Utility

The primary goal of all the client is to achieve most satisfaction from all the commodities they are proudly owning. Utility means the profit that can be obtained from the product.

Terms which are primarily used on this, the regulation is complete utility and marginal utility. Complete utility means utility derived from totally different commodities utilized by the buyer. Marginal utility means utility derived from the consumption of a further commodity.


  • “The additional satisfaction which an individual drives with a given improve in consumption of a commodity reduces with each improve within the commodity that he already has. “


  • Marginal Utility = Utility from Q2 -Utility from Q1
  • Thus, Complete Utility = Sum of all marginal Utility


Let us understand the stated regulation with an example:

Alex is a fan of goodies. By consuming 1 chocolate, he gets the utility of 30 Utils (a measurement of satisfaction). With the consumption of 2nd chocolate, he will get the satisfaction of 50 Utils and further satisfaction is given in the under desk:

Economics Example-3.1

From the above desk calculate the Marginal Utility.

Answer :

Marginal Utility = Complete Utility at Q2 – Complete Utility at Q1

Thus, Marginal utility is derived within the under table:

Marginal Utility-3.2

We will see that, with a rise in consumption, Complete utility is growing; nevertheless, it is increased with a reducing price. This is clearly seen in the Marginal utility figures, which is consistently decreasing and even goes damaging because, after the consumption beyond one point of time, it might lead to sickness. Subsequently, Alex has to stop the consumption and his utility from the chocolate will keep on decreasing.

The identical is clear from the under graph:

Marginal Utility -3.3


  1. When Complete Utility Rises, the Marginal Utility diminishes.
  2. When complete utility is most, the Marginal utility is Zero.
  3. When complete utility is diminishing, the marginal utility is adverse.

This regulation helps us in understanding how shopper reaches equilibrium in any commodity and how their taste and choice will get affected. Marginal Utility curve is downward sloping, that exhibits shopper will go on buying a great till the marginal utility of good turns into equal to the market worth. Right here his satisfaction might be most.

Economics Example 4 – Regulation of Demand

The regulation of demand is one of an important laws of economic principle

This regulation states that

Other issues stay static, With the reduction in costs, the quantity demanded of it’ll improve and with an increase in the worth of the commodity, the quantity demanded of it should decrease. Thus, there’s an opposite relationship exist between worth and quantity demanded, different issues being static.

Demand means the Quantity of items or providers that buyers are prepared to purchase a given set of worth and level of time.

This can be understood with the assistance of the demand schedule and demand curve:

Let’s take the instance of Commodity X, having totally different units of worth and the amount demanded out there as given under:

Economics Example-4.1

When the worth of the commodity is $ 5, the demand of the product is 10 unit, as worth falls to $4, there’s the demand of 15 models, similarly, with further discount up till $ 1, the demand of the commodity reaches till 60 models. This exhibits the inverse relationship between the worth of the commodity and the amount demanded of the commodity.

Let’s plot the above knowledge within the demand curve,

Economics Example -4.2

On Y-axis, we’ve plotted worth, and on X-axis, we now have plotted quantity demanded. We have now mapped all costs with respective demand of the commodity at level A, B, C, D & E. Then we have now drawn curve passing via all the factors, this curve is termed because the demand curve.


  1. Individuals will buy extra amount at a lower cost because they need to equalise the marginal utility of the commodity and its worth. This is termed as the regulation of diminishing the marginal utility
  2. When the worth of a commodity falls, it becomes relatively cheaper than other commodities. It forces shoppers to exchange the commodity whose worth has decreased for other commodities, which has turn into comparatively expensive. This is termed as substitute effect
  3. When the worth of the product falls, the identical shopper can purchase more commodity at lesser money. In different words, with a reduction in worth shopper’s purchasing energy will increase, i.e., actual revenue will increase. That is termed as revenue impact.
  4. With a discount in worth, extra shopper will begin shopping for it as shoppers, in past, who can’t afford to buy it, might now afford it
  5. Few commodities have a spread of use. If their worth falls, individuals will begin utilizing the identical for a spread of functions and will try to fulfill their utility with the identical commodity.


Thus, economics helps in understanding human tendency is totally different within the state of affairs of the business. It helps in analysing human behaviour based mostly on their need, style, choice and so forth. Moreover, it additionally helps in estimating the behaviour of shopper based mostly on the economic cycle and demand & Provide of commodities.
