In a monopolistically competitive market, how does an increase in advertising strategies typically affect consumer surplus, assuming demand remains constant?

In a monopolistically competitive market, an increase in advertising can lead to higher consumer awareness and potentially higher demand for a specific product. This means that consumers may be more willing to buy that product, even at a higher price, because they perceive it as more desirable or unique due to the advertising. As a result, the producer can increase their prices, which might reduce consumer surplus, the difference between what consumers are willing to pay and what they actually pay. For example, if a new soda brand uses catchy ads to attract attention and raises its price, some customers might still buy it because they feel it is special, but those who are price-sensitive might feel worse off. Overall, while advertising can enhance a product's appeal, it may lead to a decrease in consumer surplus if prices rise significantly.
