Understanding Economic Growth and Inflation

What is Economic Growth?

Economic growth refers to the increase in the production of goods and services within an economy, typically measured over a long period, such as a year. It is expressed as a percentage increase in the real gross domestic product (GDP), which accounts for inflation.

Calculating GDP

There are two primary methods for measuring an economy's total production:

1. Expenditure Approach: This method sums up all spending on goods and services by households, businesses, governments, and foreign entities. The formula is GDP = C (consumer spending) + I (investment spending) + G (government spending) + (X - M) (net exports).
2. Income Approach: This method calculates the total income earned by all households within a nation.

The Expenditure Approach in Detail

The expenditure approach considers the spending of various economic actors:

• Households: Consumption of goods and services.
• Firms: Investments in capital goods and inventories.
• Governments: Spending on public goods and services.
• Foreigners: Net exports (exports minus imports).

Understanding Inflation

Inflation occurs when there is a sustained increase in the general price level of goods and services, eroding purchasing power. It can distort prices and disrupt market stability.

Causes of Inflation

Identifying the causes of inflation is crucial for formulating effective economic policies. Two primary types of inflation are:

Demand-Pull Inflation

This type of inflation arises when the demand for goods and services surpasses the available supply at current prices, leading to price increases.

Cost-Push Inflation

Cost-push inflation occurs when rising production costs, such as raw materials or wages, force businesses to raise prices to maintain profit margins.
