Final answer:
Under the UCC, sellers are often viewed as experts and held responsible for sales transactions. They must ensure their goods or services meet quality standards, facilitated by mechanisms such as warranties to protect buyers from imperfect information.
Step-by-step explanation:
Under the Uniform Commercial Code (UCC), the individuals who are treated as "experts" and are held responsible for problems associated with sales transactions are typically the sellers of goods and services. Sellers are considered to have more knowledge about the item or service being provided and therefore have the responsibility of ensuring that what they are selling meets the quality standards implied or expressly stated during the sale. The UCC provides mechanisms such as warranties, both express and implied, to reduce the risks that buyers face due to imperfect information. These mechanisms are important, because buyers often cannot be experts in the quality of items like gemstones or used cars, nor can employers and lenders predict with perfect accuracy how employees and borrowers will perform. It is through these mechanisms that equitable transactions can proceed, with a reduced risk for both parties.
