Verified step by step guidance

1. Understand that in microeconomics, output refers to the amount of goods or services produced and exchanged in the market.
2. Recall that market equilibrium occurs where the quantity demanded equals the quantity supplied, and the market clears at the equilibrium price.
3. Recognize that when analyzing consumer and producer surplus, the focus is on the quantity of goods actually bought and sold at this equilibrium price.
4. Therefore, output is typically measured by the quantity of goods exchanged at the market equilibrium price, as this reflects the actual market activity.
5. Note that other options like the difference between surpluses, total revenue, or price elasticity of demand are related concepts but do not directly measure output.
