tuloelastisuutta

Tuloelastisuus, also known as income elasticity of demand, is an economic concept that measures the responsiveness of the quantity demanded for a good or service to a change in the real income of consumers. It is calculated as the percentage change in quantity demanded divided by the percentage change in real income.

Goods can be classified based on their tuloelastisuus. If the tuloelastisuus is positive, the good is considered a normal good. This means that as consumer income increases, the demand for the good also increases. Within normal goods, there are necessities and luxury goods. Necessities have an income elasticity between 0 and 1, meaning demand increases with income but at a slower rate than income. Luxury goods have an income elasticity greater than 1, indicating that demand increases more than proportionally with income.

Conversely, if the tuloelastisuus is negative, the good is considered an inferior good. In this case, as consumer income increases, the demand for the good decreases. Consumers tend to switch to more desirable alternatives as their purchasing power grows.

Tuloelastisuus is a crucial metric for businesses and policymakers. For businesses, it helps in forecasting demand based on expected changes in income levels and in segmenting their markets. For policymakers, understanding tuloelastisuus can inform decisions regarding taxation and social welfare programs, as it sheds light on how different income groups respond to economic changes. The value of tuloelastisuus can vary significantly across different goods and services and is influenced by factors such as cultural preferences and the availability of substitutes.
