Micro Economics and Macro Economics | Engineering Economics

The study of economics is broadly divided into two categories:

  1. Micro Economics
  2. Macro Economics

In our previous article “Introduction to Building Economics as related to Architecture“, we discussed certain important terms relating to Building Economics. This article is the continuation of the study of Micro Economics and Macro Economics. This article will give you a brief idea of Macro Economics and Micro Economics.

Micro Economics

It is a small part of whole economics which deals with individuals, their needs, their behaviour, individual firms and its activities. This deals with studies like incomes, capital spending on building, individuals who are engaged in various products for building construction.

Micro-economics is also called Price Theory.

Importance of Micro-economics

It analyses how millions of consumers and producers in an economy take decisions about products and services offered. It also deals with how buildings and services are distributed belonging to different economic status.


  • It cannot give an idea of the function of the economy as a whole.
  • It assumes full employment which is a rare phenomenon in developing countries or even developed countries which is quite unrealistic.

Macro – Economics

It deals with aggregates and averages of entire economics like national income, aggregate products, aggregate outputs, total employment, total consumption, savings and investments, aggregate demand, aggregate supply, general level of prices. Here it also studies how these aggregates are fluctuating and affecting the economic growth of the country.

Macro Economics is also called Income Theory.


  • Individual is altogether ignored.
  • It overlooks individual differences, the general level of prices may be assumed stable, but the food grains and building materials and consumer goods may go up very high which may cause havoc for the poor and middle class.


According to some eminent economists, the subject matter of economics includes the Price Theory (micro-economics), income theory (Macro-economics), employment theory, growth theory. All these are interdependent on each other.
