Why do warranties exist?

Answer: Reduce purchase risk signal quality

Companies fix all defects free — Wrong. Warranties are limited—they cover manufacturing defects for a period, not all damage (misuse, wear, accidents). Companies carefully define coverage terms. Warranties reduce perceived risk, encouraging purchases, but don't cover everything.

Reduce purchase risk signal quality ✓ — Correct! Warranties reduce buyer risk by guaranteeing repair or replacement if products fail. This overcomes purchase hesitation. They also signal quality—confident manufacturers offer longer warranties. Additionally, warranty data helps companies identify defects and improve products. Some extended warranties are profitable profit centers.

Increase product prices — Wrong. While warranty costs are factored into prices, price increase isn't why they exist. Warranties serve to reduce purchase barriers, signal quality confidence, and protect consumers. The competitive advantage from offering warranties often outweighs the cost.
