Final answer:
Guilds influenced the economy by setting prices, wages, and quality standards, thus impacting profitability for members.
Explanation:

The restriction on entry into privileged industries limited competition and allowed established producers protection in the market. The liberalization that followed, including the reduction of guild power, led to a freer movement of capital and labor, contributing to the expansion of a market economy.
