Most Important Diagrams in Microeconomics and Macroeconomics

Know the topics for CBSE Class 11 and 12 which have diagrams to be remembered.

By Topperlearning Expert 07th Aug, 2020 08:00 pm

When we study Economics and as we go through the chapters, what immediately captures our attention is that most concepts are interpreted through diagrams. Be it from the basic concept of demand and supply in Microeconomics to the concept of excess demand in Macroeconomics, every relationship or variable is presented diagrammatically.

 

So, a question usually pops up while writing an answer: Is it necessary to incorporate diagrams?

The answer is yes! The reasons are many. Diagrams help you to visualise and interpret relationships between factors which are important. They enable understanding of economic concepts. And to top your class, they can play the game changer to help you score higher marks—a student with neater diagrams always gets more marks among classmates with answers which read alike. While diagrams used in answers give the examiner a good impression, it is important that they are only used in relevant questions. 

 

Both Microeconomics and Macroeconomics have diagrams which you should not miss when studying.

To make your preparation simple, below is a list of important topics which have diagrams. You must revise these thoroughly.

 

Topics in Microeconomics and Macroeconomics with diagrams

 

MICROECONOMICS

Production Possibility Frontier

Utility [Total and Marginal]

Law of Diminishing Marginal Utility 

Consumer’s Equilibrium

Indifference Curve 

Movements and Shifts in Demand Curve

Movements and Shifts in Supply Curve

Total Product, Average Product and Marginal Product

Cost Curves

Revenue Curves 

Market Equilibrium 

 

MACROECONOMICS

Average and Marginal Propensity to Consume

Average and Marginal Propensity to Save

AD-AS Approach

Saving-Investment Approach

Excess and Deficient Demand

Inflationary and Deflationary Gap

Exchange Rate under Free Market

 

Now that you have this list of important concepts which have diagrams, note them down and do not miss practising these diagrams and using them in your answers.

 

 

Diagrams in Economics

 

When it comes to incorporating diagrams in your answers, remember these few points.

 

  1. A picture or diagram can say more. It gives the examiner an impression that you have clearly understood the concept. Use diagrams appropriately.
  2. Use diagrams only for relevant questions and not in every answer.
  3. Marks are especially allotted for diagrams in questions. Use them in your answer to get those bonus marks.
  4. All diagrams may not be related to a schedule. Combine the two only when required to avoid any confusion and error.
  5. Diagrams must be clearly visible and points must be accurate. 
  6. Labelling of axes, curves and equilibrium is important. 
  7. Don't try to mug up the diagram. Practise and understand the concept using the diagram.

 

 

Incorporate a diagram in your answer

 

We’ll look at a question to learn how you can incorporate a diagram in your answer.

 

Question: Explain national income equilibrium through the aggregate demand and aggregate supply approach by using a diagram.

 

Answer

According to Keynesian theory, the equilibrium level of income in an economy is determined when the AD (C+I) curve is equal to the total output AS.

Equilibrium level of income is attained only when the aggregate demand is equal to the aggregate supply.

The determination of equilibrium by the aggregate demand and aggregate supply approach (AD and AS approach) can be explained with the help of the following diagram.

 

In the diagram, we see that AD and AS intersect at point E. This is the equilibrium point where planned expenditure (spending on consumption and investment) is exactly equal to the level of planned output. OQ is the equilibrium level of output corresponding to point E. This situation is also termed effective demand. 

So, in conclusion, the three most important things to note when it comes to diagrams in Economics are

  1. The most important topics which have diagrams
  2. The importance of incorporating diagrams in answers
  3. How to incorporate a diagram in an answer
