Cost-push inflation is a type of inflation that occurs when the prices of production inputs such as labor and raw materials increase, leading to higher prices for finished goods. This type of inflation is also referred to as "supply-side inflation."
One way to illustrate the concept of cost-push inflation is through the use of a diagram. In a cost-push inflation diagram, the vertical axis represents the price level, while the horizontal axis represents the quantity of goods and services produced.
At the initial price level (P1), the quantity of goods and services produced (Q1) is at equilibrium, meaning that the quantity of goods being produced is equal to the quantity being demanded. However, if there is an increase in the cost of production inputs such as labor or raw materials, this will shift the aggregate supply curve to the left, as shown by the shift from AS1 to AS2.
As a result of the shift in the aggregate supply curve, the equilibrium price level increases from P1 to P2, while the equilibrium quantity of goods and services produced decreases from Q1 to Q2. This decrease in the quantity of goods and services produced, combined with the increase in prices, results in cost-push inflation.
It's important to note that cost-push inflation can be caused by a variety of factors, including increases in taxes or regulations, as well as supply disruptions or natural disasters that affect the availability and cost of raw materials.
In order to combat cost-push inflation, governments and central banks may use a variety of tools such as monetary policy, fiscal policy, and supply-side policies. For example, the central bank may increase interest rates in order to reduce demand and cool down the economy, while the government may implement policies to increase the efficiency and competitiveness of producers in order to increase the supply of goods and services.
Overall, understanding the causes and consequences of cost-push inflation is important for both policymakers and individuals, as it can have significant impacts on the economy and the cost of living. A cost-push inflation diagram is a useful tool for visualizing and understanding these impacts.
