Review Questions

• Explain how warranties can help address the problem of asymmetric information in a market.
  • Warranties can help address the problem of asymmetric information by signaling the quality of a product to buyers. When a seller offers a comprehensive warranty, it indicates that they are confident in the durability and reliability of their product, as they are willing to bear the cost of any necessary repairs or replacements. This helps to reduce the information gap between the seller, who has more knowledge about the product's quality, and the buyer, who may have less information. By providing a warranty, the seller is essentially putting their money where their mouth is, which can reassure buyers and encourage them to make more informed purchasing decisions.
• Describe how warranties can mitigate the problem of moral hazard in a market.
  • Warranties can help mitigate the problem of moral hazard by incentivizing manufacturers to produce higher-quality goods and provide better after-sales service. If a manufacturer offers a warranty, they are essentially taking on the risk of product failure or defects. This creates a strong incentive for them to ensure that their products are durable and reliable, as they will be responsible for the cost of any necessary repairs or replacements. Additionally, the threat of having to honor the warranty can motivate manufacturers to invest in better quality control and customer service, as they want to minimize the number of warranty claims they have to fulfill. By aligning the interests of the manufacturer and the buyer, warranties can help to reduce the moral hazard that can arise from information asymmetries.
• Evaluate the role of warranties in addressing the problem of adverse selection in a market.
  • Warranties can play a crucial role in addressing the problem of adverse selection by allowing buyers to distinguish between high-quality and low-quality products. When a seller offers a comprehensive warranty, it signals to buyers that they are confident in the quality of their product and are willing to stand behind it. This can help to prevent a situation where buyers are unable to accurately assess the true quality of a product, leading them to select the cheaper, lower-quality option (adverse selection). By providing a warranty, sellers are effectively putting a stamp of approval on their product, which can give buyers the confidence to choose a higher-quality item, even if it comes at a slightly higher price. In this way, warranties can help to ensure that the market is not dominated by lemons (low-quality products), and that buyers are able to make more informed purchasing decisions.
