Cost-push inflation refers to a type of inflation that occurs when there is an increase in the cost of producing goods and services, leading to a rise in their prices. This increase in production costs typically originates from factors that are external to the demand for goods and services. For example, if the cost of raw materials, labour wages, or manufacturing components increases, businesses may pass these higher costs on to consumers in the form of higher prices for their final products. This type of inflation can reduce the purchasing power of consumers and potentially lead to a decrease in overall economic output if businesses cut back on production due to reduced profitability or consumer demand weakening.
Causes of Cost-Push Inflation
Cost-push inflation typically arises from an increase in the costs of the factors of production:
Wage Increases:
When labour unions or market forces lead to higher wages that are not offset by corresponding increases in labour productivity, businesses' production costs rise.
Raw Material Price Hikes:
Increases in the cost of essential raw materials, such as oil, metals, or agricultural products, directly translate into higher production costs for industries that rely on them.
Supply Shocks:
Disruptions to the supply chain due to natural disasters, geopolitical events, or pandemics can reduce the availability of goods or components, driving up their prices.
Increased Taxes:
Higher indirect taxes imposed by the government on goods and services or production processes can increase the cost for businesses, which may then be passed on to consumers.
Monopolies/Oligopolies:
Firms with significant market power can sometimes raise prices even if costs do not increase, but increased input costs can be more easily passed on in less competitive markets.
Effects of Cost-Push Inflation on the Economy
Cost-push inflation can have several effects on an economy:
Reduced Purchasing Power:
As prices of goods and services rise, the real income of consumers decreases, reducing their ability to purchase the same quantity of goods as before.
Lower Economic Growth:
Businesses may face reduced profit margins due to higher production costs. This can lead to decreased investment, scaled-back production, and potentially job losses, slowing economic growth.
Wage-Price Spiral:
Higher prices might lead workers to demand higher wages, which in turn increases production costs further, potentially creating a cycle of rising wages and prices.
Decline in Competitiveness:
If domestic prices rise faster than those in other countries, a nation's exports may become more expensive, reducing their competitiveness in international markets.
Uncertainty for Businesses:
The unpredictable nature of rising input costs can make business planning more difficult, impacting long-term investment decisions.
Cost-Push vs. Demand Pull Inflation
Cost-push and demand-pull are two distinct types of inflation, differing in their origin.
Feature
| Cost-Push Inflation
| Demand-Pull Inflation
|
Origin
| Caused by increases in the cost of production (supply-side factors)
| Caused by an increase in aggregate demand outstripping supply (demand-side factors)
|
Initial Effect
| Higher production costs lead to higher prices
| Excess demand leads to higher prices
|
Supply Curve
| Shifts aggregate supply curve to the left (decreased supply)
| Shifts aggregate demand curve to the right (increased demand)
|
Output
| Often associated with reduced output
| Often associated with increased output in the short run
|
Example
| Rise in crude oil prices, increasing transportation costs
| Government spending increases, sudden consumer confidence surge
|
Scenario
| "Too few goods chasing too much money" (less common)
| "Too much money chasing too few goods" (more common)
|
Examples of Cost-Push Inflation
Several historical and contemporary situations illustrate cost-push inflation:
1970s Oil Crisis:
A classic example occurred in the 1970s when the Organization of Arab Petroleum Exporting Countries (OAPEC) imposed an oil embargo and significant price increases. As oil is a fundamental input for many industries (transportation, manufacturing, energy production), the surge in oil prices led to a broad increase in production costs across economies, resulting in widespread cost-push inflation in many industrialised nations.
Wage-Driven Inflation:
In some economies, strong labour unions successfully negotiate significant wage increases for workers. If these wage increases are not matched by improvements in worker productivity, the higher labour costs become a direct cost for businesses. Companies then pass these increased wage costs onto consumers through higher prices for their goods and services.
Supply Chain Disruptions:
The global economic environment following the COVID-19 pandemic saw instances of cost-push inflation. Lockdowns, factory closures, and transportation bottlenecks led to shortages of various components and raw materials, including semiconductors, lumber, and shipping containers. These supply chain disruptions increased the cost of inputs for manufacturers globally, compelling them to raise prices for finished products.
Agricultural Price Spikes:
Extreme weather events, such as droughts or floods in major agricultural regions, can severely impact crop yields. A reduced supply of staple food crops leads to higher prices for agricultural raw materials. Food processing companies, facing higher input costs, then increase the prices of processed food products sold to consumers.
Imported Inflation:
For countries heavily reliant on imports, a significant depreciation of the domestic currency can make imported raw materials and components more expensive. This increase in the cost of imported inputs can lead to higher production costs for domestic industries, contributing to cost-push inflation within the country.
How is Inflation Measured?
Inflation is typically measured by tracking changes in the prices of a basket of goods and services over time. Key indices used for measurement include:
Consumer Price Index (CPI):
Measures the average change over time in the prices paid by urban consumers for a market basket of consumer goods and services. It reflects the cost of living.
Wholesale Price Index (WPI):
Measures the average change in the prices of goods at the wholesale level, before they reach retailers. It captures price movements in production and raw materials.
Producer Price Index (PPI):
Calculates the average change in the prices at which domestic producers sell their goods. It tracks prices from the seller's perspective.
GDP Deflator:
A measure of the level of prices of all new, domestically produced, final goods and services in an economy. It is broader than CPI or WPI.
Conclusion
Cost-push inflation occurs when the overall price level rises due to increases in the cost of production, such as higher wages, raw material prices, or supply chain disruptions. This type of inflation can reduce purchasing power, impact economic growth, and potentially lead to a wage-price spiral. It fundamentally differs from demand-pull inflation, which originates from excessive aggregate demand. Understanding the causes and effects of cost-push inflation is a part of analysing economic conditions and their potential implications.
