If a monopolist is able to successfully implement imperfect price discrimination, what is the likely effect on consumer surplus in the market?

When a monopolist uses imperfect price discrimination, they charge different prices to different consumers based on their willingness to pay. This means that some consumers might pay more while others might pay less, but overall, the monopolist captures more of the total market revenue. Because of this pricing strategy, consumer surplus, which is the benefit consumers get from paying less than they are willing to pay, tends to decrease. For example, if a monopolist sells a movie ticket for $10 to one person who would have paid $15, and $5 to another who would have paid $7, the total consumer surplus is lower than if everyone paid the same lower price. In the end, the monopolist makes more profit, but consumers gain less overall benefit from their purchases.
