In a market equilibrium scenario, how does an increase in consumer surplus relate to welfare economics?

In welfare economics, consumer surplus is an important concept that shows how much extra benefit consumers receive when they pay less for a good than what they are willing to pay. When consumer surplus increases, it means that consumers are getting more value from their purchases, which indicates that they are happier and better off. This can happen if prices fall or if consumers' preferences change in a way that they value the product more. For example, if a new smartphone is priced lower than expected, more people can afford it, leading to a larger consumer surplus. Overall, an increase in consumer surplus suggests that the market is functioning well and contributing positively to the overall welfare of society.
