What is cost-push inflation?
Cost-push inflation occurs when businesses raise their prices because the cost of things like raw materials or wages has gone up. These higher production costs can also lead to a drop in aggregate supplyβmeaning businesses, in general, produce fewer goods. When demand stays the same but thereβs less available to buy, prices tend to rise.
This cost-push inflation graph shows how rising production costs can lead to higher prices for consumers, even when demand stays the same.
In most cases, cost-push inflation happens when it becomes more expensive for businesses to make or supply their products. This can be expected or come as a surpriseβlike when the price of raw materials suddenly goes up. If customers still want the product just as much as before, businesses may increase their prices to cover the higher costs. This helps them protect their profits while continuing to meet customer demand.
A related concept is demand-pull inflation, which happens when more people want to buy a product than there are products available, so prices go up. The essential difference between demand-pull and cost-push inflation is:
- Demand-pull: Prices rise because demand increases
- Cost-push: Prices rise because supply costs increase
Cost-push inflation example: Rising fuel and food prices
Imagine a scenario where fuel prices rise sharply in Australia due to global oil supply issues. This affects transport companies, who now spend more to deliver goods across the country. Supermarkets rely on these transport services to stock fresh produce, meat, and packaged goods.
As delivery costs increase, supermarkets face higher operating expenses. To cover these extra costs, they raise prices on everyday items like fruit, vegetables, and bread.
Even though people are still buying the same amount of groceries, they now pay more at the checkoutβnot because demand has changed, but because the cost of getting goods to shelves has gone up.
Cost-pull inflation or cost-push inflation: Which is it?
The correct term is βcost-push inflationβ.Β
Although the term βcost-pull inflationβ pops up frequently, itβs actually a mix-up of two distinct conceptsβcost-push inflation and demand-pull inflation. Understanding which one you're really dealing with can help you make better decisions about pricing, forecasting, and managing your costs.
Hereβs a quick guide:
- Cost-push inflation is driven by rising production costs. If businesses are paying more for raw materials, energy, or wages, and those extra costs are passed on to consumers, youβre likely seeing cost-push inflation.
- Demand-pull inflation happens when consumers are spending more and demand outpaces supply. If prices are rising because goods are flying off the shelves or services are booked out, demand-pull inflation is probably the cause.
Inflation is often influenced by a mix of both. For example, a surge in demand during a busy season combined with a shortage of materials can create a perfect storm of rising prices. Understanding the root cause is key for businesses and policymakers to respond effectively.
