Questions & Answers

Q: What determines the prices in a market economy?

In a market economy, prices are determined by the interaction of supply and demand. The quantity of goods traded and their market price are set based on how much consumers are willing to pay and how much sellers are willing to accept.

Q: How is consumer surplus measured, and what does it represent?

Consumer surplus is the difference between the maximum price a consumer is willing to pay for a good and the actual price they pay. It serves as a measure of how well-off buyers are in a market, as lower prices allow them to pay less than their maximum willingness to pay.

Q: What factors influence a consumer's willingness to pay?

A consumer's willingness to pay is influenced by the value they place on the good or service, considering the benefits it provides compared to alternative uses of their money. It reflects both the consumer's preferences and the opportunity cost of making the purchase.

Q: How does consumer surplus change with price fluctuations?

If prices fall, more consumers will enter the market, increasing the quantity demanded and consumer surplus. Conversely, if prices increase, consumer surplus is likely to shrink, as some consumers may no longer find the good or service affordable.
