Final answer:
Consumer expectations affect the demand for a product by influencing consumers' desire and willingness to purchase it.
Step-by-step explanation:
Consumer expectations play a significant role in affecting the demand for a product. When consumers have high expectations about a product, they are more likely to demand it, leading to an increase in demand. On the other hand, if consumers have low expectations or negative perceptions about a product, demand may decrease.
For example, if a new smartphone is highly anticipated and expected to have advanced features, consumers may eagerly wait to purchase it, resulting in high demand. Conversely, if consumers expect a product to become obsolete quickly or have poor quality, demand may be lower.
In summary, consumer expectations can impact demand for a product by influencing consumers' desire and willingness to purchase it.
