Cost-push inflation occurs when the overall price levels in an economy rise due to increases in the costs of wages and raw materials. Businesses facing higher production costs pass on these increases to consumers in the form of higher prices on goods and services. This type of inflation is distinct from demand-pull inflation, where prices rise due to increased demand.
Causes of Cost-Push Inflation
Several factors can lead to cost-push inflation:
Rising Raw Material Costs
When the costs of essential raw materials, such as oil, metals, or agricultural commodities, increase, the expenses for producers also rise. Producers recover these costs by increasing the prices of finished goods.
Wage Inflation
Increases in wages can also be a significant factor. Higher wages mean higher production costs, which businesses may then pass on to the consumers.
Supply Chain Disruptions
Issues such as natural disasters, geopolitical events, or logistical bottlenecks can disrupt supply chains, leading to increased costs for acquiring raw materials.
Examples of Cost-Push Inflation
A clear example of cost-push inflation is the oil crisis of the 1970s. The OPEC oil embargo led to skyrocketing oil prices, which increased transportation and production costs, resulting in widespread inflation.
Another instance is the rise in food prices caused by droughts and poor harvests. This scenario often leads to increased costs for agricultural products, which then influence the prices of a wide range of goods and services.
Comparison with Demand-Pull Inflation
While cost-push inflation stems from increased costs of production, demand-pull inflation is caused by heightened demand. For example, if a new technology stimulates consumer interest and spending, the increased demand results in higher prices without any corresponding rise in production costs.
Mathematical Representation
If we represent the cost-push inflation rate (\( \pi_{cp} \)) and the impact of rising costs (ΔC) using a basic formula, it can be expressed as:
where \( \Delta C \) represents the change in production costs, including wages and raw materials.
Special Considerations
Cost-push inflation can be more persistent and difficult to control than demand-pull inflation. Importantly, if the labor market is tight, rising wages can create a wage-price spiral, wherein wages and prices continually chase each other upwards. Central banks have to be cautious about raising interest rates too aggressively, as it might lead to economic stagnation without effectively curbing inflation.

Summary
Cost-push inflation is a type of inflation driven by rising production costs, particularly raw materials and wages. It manifests as businesses increase prices to offset higher costs, ultimately affecting consumers. Understanding its nuances and implications is crucial for policymakers and economists in devising strategies to manage inflation effectively.
