Economic Concepts and Inflation

Study Notes

Economic Concepts

Economics is the study of how societies allocate scarce resources to satisfy unlimited wants and needs.
Scarcity is the fundamental economic problem: unlimited wants, but limited resources to fulfill them.
Key economic concepts include:
- Needs: Basic necessities for survival (food, shelter, clothing).
- Wants: Desires that go beyond basic necessities (luxury goods, travel).

Inflation

Inflation is a sustained increase in the general price level of goods and services in an economy over a period of time.
It's measured using various indices, such as the Consumer Price Index (CPI) and Wholesale Price Index (WPI).
Causes of inflation:
- Demand-pull inflation: Occurs when aggregate demand exceeds aggregate supply. Increased demand for goods and services outpaces production capacity, leading to price increases.
- Cost-push inflation: Occurs when the cost of production increases, e.g., increased raw material prices or labor costs. Higher costs are passed on to consumers in the form of higher prices.
- Built-in inflation: This is a combination of demand-pull and cost-push inflation, feeding on itself. Higher prices lead to higher wages, and higher wages raise costs, further pushing prices up.
Effects of inflation:
- Reduced purchasing power: Money buys fewer goods and services, impacting the standard of living.
- Uncertainty in the economy: Inflation can disrupt business planning and investment decisions.
- Redistribution of income: Inflation can disproportionately affect different groups in society, potentially eroding savings and fixed incomes.
Types of Inflation:
- Creeping Inflation: A relatively mild, gradual increase in the price level (e.g., 2-3% annually).
- Galloping Inflation: A rapidly increasing price level (e.g., 10-100% annually).
- Hyperinflation: An extremely rapid increase in the price level (e.g., exceeding 100% annually), often associated with serious socioeconomic issues.
Controlling Inflation:
- Monetary policy tools: Actions by the central bank, such as adjusting interest rates and managing the money supply, aim to control the money circulating in the economy and reduce inflation.
- Fiscal policy measures: Government actions, such as controlling government spending and taxation, can impact aggregate demand and, consequently, ease inflationary pressures.
- Supply-side policies: Focus on increasing output and production in the economy to counter inflation.
- Wage-price controls: Attempting to curb wages and prices to cool down the economy, often criticized for creating shortages or inefficiencies.

Economic Growth

Economic growth is an increase in the production of goods and services in an economy over a period of time.
It's often measured by changes in Gross Domestic Product (GDP).
Factors contributing to economic growth:
- Investment in physical capital (machinery, technology)
- Investment in human capital (education, skills development)
- Technological progress and innovation
- Natural resources
- Entrepreneurship

Relationship between Inflation and economic growth

Inflation can sometimes be beneficial for economic growth: some moderate inflation can encourage investment and spending.
However, high inflation is generally detrimental to economic growth as it erodes purchasing power and creates uncertainty. High inflation can also reduce investment as businesses find it difficult to plan.

Deflation

Deflation is a sustained decrease in the general price level of goods and services in an economy.
Causes of deflation can include a decrease in demand, a decrease in money supply, or an increase in productivity.
Effects of deflation can include decreased consumer spending, lower investment, higher real interest rates and potential economic recession.
