Inflation in Economics:

Inflation, sometimes called price inflation is an important factor that will affect the citizens and residents of a nation either directly or indirectly. Interestingly, certain people gain from the events of inflation while others suffer from it.

You can read on the concept of citizens and residents here.

In economics, inflation (or price inflation) is defined as a gradual and sustained rise in price level of goods and services in relation to their availability; which will inturn lead to a decrease in the purchasing power of a nation's currency.

Inorder to simplify the above definition, let's consider an instance using the nation Nigeria as our point of reference.

You can read on the Nigerian National Symbols here.

Back in the days (let's say 1970), the Nigerian Naira (one naira) had a higher value than the American Dollar (one dollar). Infact, during that time, it was considered to be equivalent to the British Pound (one pound). Now, fast forward to October 2020, four hundred and sixty five naira (₦465) is equivalent to one dollar ($1) in the Nigerian black market. Using the parallel market as an instance, ₦385 becomes equivalent to $1.

Please read on black market, its advantages and disadvantages here.

From the above instance, if Nigeria import phones from America at one dollar each (in 1970), such phone will sell at a price lower than one naira. This is true because the Nigerian Naira at that time had a greater value than the American Dollar; and as such, ₦1 naira will purchase 2 phones since it's equivalent to $2 (as at 1970). To simply put it, the importer exchanges ₦1 for $2 in order to buy phones from America.

You can read more on foreign trade here.

On the contrary, the above instance of a phone which sells at price lesser than ₦1 in 1970 will now sell at a minimum of ₦385 in October, 2020. This becomes a fact because the Nigeria naira has lost its value to an extent that $1 is now equivalent to ₦385 in the parallel market.

The loss of monetary value is exactly what inflation does to the purchasing power of a nation's currency and the citizens ultimately suffers from this, especially if such country focuses more on the importation of products and services.

Please read on balance of trade and balance of payments here.

From the above explanations, Nigeria used to be a better country in 1970. During that time, the cost of living was quite low and the citizens could easily afford the basic amenities of life. As at now, the reverse is the case and corruption (birthing inflation) is its root.

Please read on your responsibilities, duties and obligations as a citizen here.

If you are a teenage student reading this article, kindly ask your parents or an elderly person about the cost of living during their days and in comparison to now (as at October 2020). Their answer should give you a perfect clue to what inflation does to a nation.

Note: Inflation isn't always a bad thing.

In another instance, a brand new car in Nigeria may cost about N2,000 back in the days; but fast forward to now, an equivalent car will cost over ₦1,000,000. Understand that the increase in the price of a car isn't due to the scarcity of cars; rather it was caused by the decreased value of the Nigerian Naira as a result of inflation.

Please read on elasticity of supply here.

Once again, it is important to state that inflation reflects a reduction in the purchasing power (or value) per unit of money.

At the time of writing this article, inflation had made 10 Kobo, 50 Kobo, 1 Naira and even 5 Naira valueless in Nigeria.

According to economists, when too much money circulates in an economy,  high rate of inflation (hyperinflation) results. To this end, we could also have low to moderate rates of inflation and such are believed to be caused by fluctuations in the demands of goods and services (or changes in the quantity of goods supplied and services rendered) during the periods of scarcity.

Please read on the concept of demand here.

In general, inflation becomes imminent when the economic growth of a nation occurs at a slower rate while a corresponding increase in money (within the economy) occurs at a rapid rate. In summary, inflation is generally seen in country that imports more and produces less.

Note: Inflation can affect a nation both positively and negatively.

Amazing facts in Economics


The law of supply states that:

The quantity of the supplied services or goods will increase as the price increases and they will decrease as the price decreases provided all other factors remain constant.

These constant factors are very important when stating the supply law. They include:

  • The price of Input resources

  • The kind of technology used during production

  • The number of suppliers

  • The number of buyers; and so on.


A graph that shows the relationship between the price of a product or service, and its quantity supplied is the supply curve.

Supply curve can be defined as a graphical representation of the direct relationship between the prices of goods and services and the quantity supplied (of such goods and services) within a particular period of time provided all other factors remain constant.

The above table shows us what a scale of preference would look like.

A scale of preference can be defined as the list of a person's needs or wants written in an order of importance.

You will observe that the person puts his most important needs or wants at the top of the list. Further down the list are his less important needs.

Now, let's imagine that this individual has 170,000 Naira to spend. According to the above scale of preference, the followings can be deduced;

  • A phone will be considered to be the most important; and it costs 50,000. He buys the phone.

  • A console game according to this person is next in importance; and it costs 120,000. He buys the console game.

Another question worth asking is:

  • What happens to his other needs?

This is where the term 'Opportinity Cost comes into play.

Scale of Preference can be defined as the list of a person's needs or wants written in an order of importance. 📜✍️

When you have a limited amount of money and could only buy some of the items on your list (the top items on the list); then the remaining items that you didn't buy will be generally considered as your opportunity cost.

Opportunity cost can be defined as the value of the best alternative that a person could have achieved or bought but couldn't achieve after the best choice had been achieved.

Opportunity cost are of two types. They are:

  1. Explicit Opportunity Cost
  2. Implicit Opportunity Cost
