How does a change in demand affect consumer surplus and producer surplus?

A change in demand can affect consumer surplus and producer surplus in the following ways:

1. Increase in demand: When there is an increase in demand, the consumer surplus decreases while the producer surplus increases. This is because consumers are willing to pay higher prices for the product, resulting in a smaller difference between the price they are willing to pay and the actual market price. On the other hand, producers can charge higher prices and still sell their products, leading to an increase in their surplus.

2. Decrease in demand: When there is a decrease in demand, the consumer surplus increases while the producer surplus decreases. This is because consumers are not willing to pay as much for the product, resulting in a larger difference between the price they are willing to pay and the actual market price. As a result, consumers can obtain the product at a lower price, increasing their surplus. However, producers may have to lower their prices to attract buyers, reducing their surplus.

Overall, changes in demand can have a direct impact on both consumer surplus and producer surplus, with an increase in demand benefiting producers and a decrease in demand benefiting consumers.
