Income Effect Dominates The Substitution Effect

The decrease in quantity demanded due to increase in price of a product.

Income effect dominates the substitution effect. If you have a lot of debts and spending commitments the income effect will take a long time to occur. But in case of an inferior good income effect operates in the opposite direction to the substitution effect. The income effect expresses the impact of increased purchasing power on consumption while the substitution effect describes how consumption is impacted by changing relative income and prices. The income effect will soon dominate.

If the price of an inferior good falls the substitution effect will still cause a larger commodity. Income effect and substitution effect are the components of price effect i e. Income and substitution effect for interest rates and saving. Many studies have demonstrated that the price elasticity of labor supply is positive meaning that the substitution effect dominates more than the income effect in aggregate.

This is essential to a fundamental knowledge of labor market economics as we understand it today. Income effect arises because a price change changes a consumer s real income and substitution effect occurs when consumers opt for the product s substitutes. Higher interest rates increase income from saving.
