Economics is broadly classified into two types
- Microeconomics is a branch of economics that studies the behaviour of individual consumers and organisations in the market. It focuses on the demand and supply, pricing, and output of individual organisations.
- Macroeconomics examines the economy as a whole and deals with issues related to national income, employment pattern, inflation, recession, and economic growth.
Managers should have a clear understanding of different economic concepts, theories, and tools. Business economics or managerial economics is a specialized discipline of economics that undertakes a study of various economic theories, logics, and tools used in business decision making.
Meaning of Economics
In the meaning of economics, the term ‘Economics’ owes its origin to the Greek word ‘Oikonomia’, which can be divided into two parts: oikos means home and nomos means management.
Thus, in earlier times, economics was referred to as home management where the head of a family managed the needs of family members from his limited income.
Till the 19th century, Economics was known as ‘Political Economy.’ The book named ‘An Inquiry into the Nature and Causes of the Wealth of Nations’ (1776) usually abbreviated as ‘The Wealth of Nations’, by Adam Smith is considered as the first modern work of Economics.

Assumptions in Economics
There are certain assumptions in economics about an economic situation to happen in the future. Economists use assumptions to break down complex economic processes and advocate different theories to understand economic variables.
Three important assumptions in economics, are as follows:
- Consumers have rational preferences: This assumption states that consumers act in a rational manner and focus on satisfying their needs.
It is also assumed that the tastes of consumers remain constant for a long period. For instance, a consumer who is vegetarian may not change his/her preferences in the near future.
- Existence of perfect competition: According to this assumption, there is perfect competition in an economy, wherein there are numerous buyers and sellers.
It is assumed that homogenous products exist in the market and both buyers and sellers cannot affect prices.
- Existence of equilibrium: As per this assumption, equilibrium exists wherein both consumers and entrepreneurs achieve maximum satisfaction.
In a market, there can be two types of equilibrium: industry equilibrium and firm’s equilibrium. An industry is at equilibrium if profits achieved are normal. On the other hand, a firm is at the state of equilibrium if its profits are maximum.
