what is the paradox of value?
- Paradox of Value: Also known as the Diamond-Water Paradox. Explores the contradiction between market value and practical utility.
- Example: Water vs. Diamonds: Water is essential for life but has a low market price. Diamonds, with limited practical use, often have a higher market value.
- Use Value vs. Exchange Value: Use value is the practical utility or necessity of a good, while exchange value is the market price determined by supply and demand.
- Factors Influencing Value: Rarity (scarce items may have higher exchange value) and perception (aesthetic or cultural factors can influence value).
- Highlighted by Adam Smith: Classical economist who discussed this economic paradox.
