inelastic demand
Inelastic demand is when people keep buying something even after the price rises, because they cannot easily do without it.
In plain English
The day fuel price jumped at the filling station in Ojota, nobody stopped driving. The danfo drivers grumbled, adjusted their fares, and the queue at the pump was just as long the next morning. That is inelastic demand sitting right in front of you, plain as day.
Inelastic demand simply means that when the price of something goes up, the amount people buy does not fall by much, if at all. It is the opposite of something like eating out at a fancy restaurant, where if prices rise, people simply stop going and cook at home instead.
Things become inelastic when they are necessities, when there are no easy substitutes, or when people have grown used to spending on them regardless. Fuel, rice, garri, electricity, and data in many Nigerian homes all behave this way. When NEPA, sorry, when the power company raises tariffs, most households do not suddenly stop using light. They grumble, they budget tighter elsewhere, but the fridge still runs.
This matters a great deal to government and to businesses. If a product has inelastic demand, a company or the government can raise its price or its tax and still expect people to buy roughly the same amount. That is partly why fuel subsidy removal in Nigeria caused such pain rather than a simple shift to alternatives. There was nowhere else for most people to go.
In the United Kingdom, think of the way people kept paying their energy bills even as prices climbed sharply in 2022. Nobody could simply switch off heating in winter. That is inelastic demand at national scale, and it is exactly why governments sometimes step in with support, because they know the market alone will not soften the blow.
Petrol price rises from ₦600 to ₦700 per litre. Total petrol bought nationwide falls by less than 5 percent, because commuters and businesses still need to move. That small drop in quantity against a big rise in price is the fingerprint of inelastic demand.
Questions people ask
What makes a product's demand inelastic rather than elastic?
It usually comes down to necessity and substitutes. If something is essential, like fuel, electricity, or basic food, and there is no easy alternative, people keep buying it even when the price rises. Luxuries and items with many substitutes tend to be elastic instead, because buyers can simply switch or wait.
Why do governments care whether demand is inelastic?
Because it affects how taxes and subsidies play out. Taxing an inelastic good, like fuel or cigarettes, raises revenue reliably since people keep buying anyway. It also explains why removing subsidies on inelastic goods causes so much public hardship, since demand does not fall to soften the price shock.
Can something with inelastic demand ever become elastic?
Yes, over time. If Nigerians eventually get better public transport options or affordable electric vehicles, petrol demand could become more elastic, because a real substitute would finally exist. Elasticity often changes as choices and habits change, not overnight, but gradually.
