In what ways did guilds ensure that trade and merchandising was ethical and moral?

Guilds ensured ethical and moral trade by establishing strict rules and regulations for their members, such as setting prices, quality standards, and prohibiting deceptive practices. Members were expected to abide by a code of conduct that emphasized honesty, fairness, and integrity in their business dealings. Guilds also provided a system for resolving disputes between members to maintain trust and uphold ethical standards within the guild.
