Study Notes
Definition and Measurement
- Inflation is a sustained increase in the general price level of goods and services in an economy over a period of time.
- It's typically measured by calculating the percentage change in a price index, such as the Consumer Price Index (CPI) or the Producer Price Index (PPI).
- These indexes track the average prices of a basket of goods and services consumed by households or produced by businesses, respectively.
- Inflation rates are usually expressed as annual percentage changes.
Causes of Inflation
- Demand-pull inflation: Occurs when aggregate demand in an economy outpaces aggregate supply. Increased consumer spending, investment, or government spending can drive up prices.
- Cost-push inflation: Arises when the cost of production increases, leading businesses to raise prices to maintain profit margins. Rising wages, raw material costs, or energy prices can be contributing factors.
- Built-in inflation: A self-reinforcing process where past inflation expectations influence current wage and price decisions. Workers demand higher wages to keep up with past price increases, leading businesses to raise prices further.
- Monetary inflation: An increase in the money supply not matched by a corresponding increase in output can lead to inflation.
Types of Inflation
- Creeping inflation: A low and gradual increase in the price level, typically a few percent per year.
- Galloping inflation: A rapid increase in prices, making it harder to plan for the future, typically a few tens of percent per year.
- Hyperinflation: An extremely rapid and out-of-control increase in the price level, often at rates exceeding 50% per month which severely damages the economy. This is extremely uncommon in modern economies.
Effects of Inflation
- Reduced purchasing power: Inflation erodes the real value of money, meaning the same amount of money buys fewer goods and services.
- Uncertainty and instability: Inflation can create uncertainty about future prices, making it harder for businesses to plan investment and for consumers to plan spending.
- Distortion of relative prices: Inflation can distort relative price signals in the market, leading to misallocation of resources.
- Income redistribution: Inflation disproportionately affects different groups in society, often benefiting debtors at the expense of creditors (those owed money).
- Economic inefficiency: Inflation can lead to reduced investment, savings, and economic growth.
- Reduced competitiveness: Inflation makes exports more expensive, potentially leading to a loss of market share in international trade.
Controlling Inflation
- Monetary policy: Central banks can use tools like adjusting interest rates to influence borrowing costs and control the money supply. Higher interest rates generally curb inflation.
- Fiscal policy: The government can use policies such as adjusting taxes and government spending to reduce aggregate demand and control inflation.
- Supply-side policies: Policies aimed at increasing the economy's productive capacity can help lower inflation by increasing the supply of goods and services.
The Phillips Curve
- The Phillips Curve illustrates an inverse relationship between inflation and unemployment.
- It suggests that lower unemployment often correlates with higher inflation, and vice versa.
- However, this relationship is not consistently observed in the long run, and the curve's shape and existence can change depending on circumstances and economic conditions.
Deflation
- Deflation is a sustained decrease in the general price level of goods and services.
- Deflation often has negative consequences for the economy, as it can lead to decreased consumption and investment, while increasing the real burden of debt.
