Cost-push inflation and its causes

Cost-push inflation arises when increases in the expenses involved in producing goods and services lead to higher prices overall. This type of inflation results from factors that raise production costs, prompting businesses to pass these on to buyers, which shifts the aggregate supply curve leftwards.

Causes of cost-push inflation

• Increases in wages exceeding productivity gains - When salaries rise faster than output per worker, firms face higher labour expenses. This can trigger a cycle where higher prices lead to demands for even greater pay rises, known as a wage-price spiral.
• Rising costs of imported raw materials - Higher global prices for essential inputs, such as commodities, force domestic producers to charge more. If a country's currency decreases in value, producers will pay more for the same imports.
• Higher indirect taxes - Increases in taxes like value-added tax (VAT) add to production costs. If demand for the affected goods is price inelastic, businesses can transfer most of this extra cost to consumers through elevated prices.

Demand-pull inflation and its causes

Demand-pull inflation happens when the total demand for goods and services grows faster than the economy's ability to supply them. This excess demand shifts the aggregate demand curve rightwards, enabling sellers to increase prices.

Causes of demand-pull inflation

• Strong consumer spending or export demand - High levels of confidence can boost household expenditure, while low interest rates make loans more affordable, encouraging further purchases. Rapid expansion in overseas economies can also heighten demand for exports.
• Money supply expanding quicker than production - When the amount of money circulating in the economy outpaces the growth in goods and services, it can drive prices up. Economists from the monetarist school argue that an oversupply of money is the primary driver of sustained inflation.
• Shortages due to resource constraints - If demand grows quickly when resources are fully used, shortages occur. Price increases in one area of the market may be copied by other markets, leading to general inflation.

Deflation and disinflation

Deflation and disinflation represent scenarios where price levels either fall or rise more slowly.

Deflation

Deflation is defined as a situation where the overall inflation rate drops below zero, meaning average prices are decreasing. It is frequently linked to declining aggregate demand, which can lead to higher unemployment. Alternatively, it may occur if businesses experience lower costs and choose to reduce prices to attract customers.

Problems associated with deflation:

• Delayed consumer purchases - People might postpone buying goods in anticipation of even lower prices, which reduces overall spending.
• Impact on businesses - Falling prices and reduced demand can erode company profits, leading to slower growth in the economy.

Disinflation

Disinflation occurs when inflation rates decrease but stay above zero, such as dropping from 4% to 1%. This indicates a slowdown in price rises without entering negative territory.

The effects and management of inflation

Inflation can have varying impacts depending on its level. Governments aim to control it through targeted policies.

Effects of different inflation levels

• Acceptable inflation - Rates up to 2% annually are generally viewed as stable and supportive of economic health.
• Excessive inflation - Levels above 2% can be harmful, as they reduce the real value of money and discourage saving.

Policies for managing inflation

Governments employ a mix of approaches to keep inflation within target ranges, often around 2%:

• Monetary policy - This includes adjusting interest rates or controlling the money supply to influence borrowing and spending.
• Fiscal policy - Changes in taxation and public spending can help regulate demand, such as increasing taxes to cool an overheating economy.
• Supply-side policies - These focus on improving efficiency and productivity, like investing in education or infrastructure, to increase supply and reduce cost pressures.

Trade-offs and economic perspectives

Achieving inflation targets often requires compromises with other aims, such as full employment or growth. Monetarist economists argue that prioritising inflation control in the short term supports the attainment of broader objectives over the longer term.
