Economics – Demand and supply curves | e-Consult

Changes in consumer tastes and preferences are a fundamental determinant of demand. A positive change in tastes (e.g., increased health consciousness) shifts the demand curve to the right, indicating higher demand at all price levels. Conversely, a negative change in tastes shifts the demand curve to the left.

Advertising plays a crucial role in shaping consumer tastes. Effective advertising campaigns can create or reinforce positive associations with a product, leading to increased demand. For example, successful advertising for organic food has contributed to a shift in demand towards organic products. Social trends also exert a powerful influence. For instance, the growing popularity of veganism has significantly increased demand for plant-based alternatives to meat. Similarly, trends in fitness and wellness have boosted demand for health foods and exercise equipment.

Example: Consider the demand for electric vehicles (EVs). Initially, demand was relatively low. However, due to increasing environmental awareness (a change in consumer taste), government incentives, and effective advertising campaigns highlighting the benefits of EVs (e.g., lower running costs, environmental friendliness), the demand curve for EVs has shifted significantly to the right. This is a clear illustration of how tastes, preferences, and marketing can influence demand.
