Meaning and Types of Variables

Introduction

In economics, variables are the indicators determining the country’s performance in terms of its economy. These variables cover a wide variety of information that helps the government make decisions to improve and solve problems in state affairs.

Variables help us determine the inflation and unemployment in the country, which helps the policymakers focus on making the policies to improve the conditions of a country and avoid economic failure within the system and make their work easier. 

Meaning of variables

First, we will understand the meaning of the word variable; it represents a concept where the variable’s value is never constant; as the name suggests, the value of the variable changes over time. It can be due to many reasons; it can be random; it might derive its value from any external factor.

When we talk about variables in economics, these are just indicators that show us the current trends in the economy. It allows us to understand the forces of economic growth, how or when prices increase, why inflation occurs, what kind of policies will be best suitable for the state.

There are many variables like GDP, inflation, economic growth, employment, and many more in economics. Variables tell us how The economy is performing in a particular area. It also helps us find a solution for many economic problems and move the economy in a forward direction.

Different Types of variables

We can categorise all the variables into two types: microeconomic variables and macroeconomics variables.

Macroeconomic variables

These variables are those types of variables that help us identify the pattern or elements of a state, country, a union of countries, or the whole world.

Some of the important macroeconomic variables are:

• GDP
• Balance of payments
• Inflation
• Economic Growth
• Employment

GDP

Its complete form is a Gross Domestic Product. It can be defined as the standard measure of value that is added and created through producing goods and services in a given country during a period.

Balance of payments

It can be defined as the difference between the number of goods sold or exported to other countries and the number of goods bought or imported from other countries. It can also be written as X-M.

If the amount of goods exported is less than the total amount of goods imported, then the country is said to have a balance of payments surplus because X is more significant than M.

If the amount of goods exported is more than the total amount of goods imported, then the country is said to have a balance of payments deficit because X is less than M.

Inflation

It is the continuous  increase in the cost of goods and services in an economy in a given period. Inflation can damage a country, so policymakers try to keep it low.

There are two types of inflation: 

• Cost inflation is caused by an increase in the cost of production, which ultimately leads to an increase in sale price.
• Demand-pull inflation is caused by a sudden increase in the demand for a product or service, which allows companies to increase their profits on the product or service.

Economic Growth

The amount of growth of the output level within an economy increases over a given period. Economic growth can be increased in several ways, such as increased workforce technological advancements. Economic growth means that people are prospering, and it is a favourable factor.

Unemployment

We can define unemployment as over the number of people in an economy who want to and can work but not have a job. 

There are many kinds of unemployment:

• Frictional unemployment: When a working individual is switching jobs for the period he doesn’t have a new job, he is considered unemployed.
• Structural unemployment: It is caused by a decline in the demand of the workforce in a particular industry. For example, after the invention of computers, typewriters were deemed redundant. This caused a decline in the demand of the workforce in that industry.
• Seasonal unemployment: It is majorly caused due to industries that depend on the season for their work. For example, Waterparks generate employment during the summers, but when winter survives, the waterparks lose business during the winters.

Microeconomic variables

Microeconomic variables describe individual economic units: a family, a person, or a company. The different types of variables are:

• Price: it is the amount of money required for payment of a goods or service
• Individual expenditure: it is the amount of money spent by an individual. It can also be the expenditure of a family, business, or individual.
• Quantity demanded: The total amount of goods or services that people or businesses are willing to buy.
• Consumption: The total amount of money that a person spends on goods or services
• Quantity produced: The number of goods produced by a person or a company in a given period.
• Wages: Amount of payment received in exchange for work or services on a regular interval time.
• Cost of Input: A set of expenditures incurred in producing or providing a product or service.
• Individual investment: It is a kind of expenditure that does not have an immediate benefit but will provide a future benefit.
• Market share of business: It is the share of sales by the company concerning the market’s total sales.

 Conclusion 

Through this study material on variables and variables, we get a better grip on the topic. We understood that a variable is simply an indicator that shows the performance of a country in its various aspects and how those variables work and or what they represent. We also learned about the different types of variables in economics and their purpose.
