what is economic surplus
An economic surplus is also known as total welfare. An economic surplus is related to money, and it reflects a gain in the expected income from a product. There are two types of economic surplus: consumer surplus and producer surplus. Consumer surplus occurs when the price for a product or service is lower than the highest price the consumer would pay. For example, think of it like an auction: a buyer walks into an auction with a set price limit he or she will not exceed.
