Consumer Behavior 101: Income and Social Class - Income Distribution Spending Patterns Engels Laws

What It Is

Income Distribution & Spending Patterns, also known as Engel's Laws, describe how household income affects consumer spending patterns. The law states that as income increases, the proportion of income spent on food decreases, while the proportion spent on non-essential goods and services increases. A canonical example of this is the rise of luxury brands in emerging markets, such as the growth of Louis Vuitton in China. This matters for understanding consumers and building marketing strategy because it highlights the importance of adapting products and pricing to different income levels and cultural contexts.

Key Terms & Concepts

• Engel's Law: A law that describes how household income affects consumer spending patterns, stating that as income increases, the proportion of income spent on food decreases, while the proportion spent on non-essential goods and services increases.
• Income Elasticity: A measure of how responsive consumer spending is to changes in income, with income elastic goods being sensitive to changes in income and income inelastic goods being less sensitive.
• Luxury Goods: High-end products that are often associated with status and prestige, such as designer clothing and jewelry.
• Essential Goods: Necessities that consumers must purchase to meet their basic needs, such as food and shelter.
• Non-Essential Goods: Discretionary products that consumers choose to purchase for pleasure or convenience, such as entertainment and travel.
• Giffen Goods: Goods that become more desirable as income increases, such as luxury cars.
• Income Effect: The change in consumer demand that occurs when income changes, with an increase in income leading to an increase in demand for normal goods and a decrease in demand for inferior goods.
• Cross-Price Elasticity: A measure of how responsive consumer spending is to changes in the price of another good, with a positive cross-price elasticity indicating that an increase in the price of one good leads to an increase in demand for another good.
• Veblen Effect: The phenomenon where consumers are willing to pay more for a product because it is perceived as being of higher quality or status.
• Pareto Distribution: A distribution of income that is highly skewed, with a small proportion of the population holding a large proportion of the wealth.
• Kuznets Curve: A curve that describes the relationship between income inequality and economic growth, with income inequality increasing during the early stages of economic growth and decreasing during later stages.
• Gini Coefficient: A measure of income inequality, with a value of 0 indicating perfect equality and a value of 1 indicating perfect inequality.
• Consumer Segmentation: The process of dividing consumers into distinct groups based on demographic, behavioral, or psychographic characteristics.
• Target Marketing: The practice of tailoring marketing efforts to specific consumer segments based on their characteristics and needs.
