What According to Adam Smith what are the two factors that regulate a marketplace?

According to Adam Smith, the two factors that regulate a marketplace are the "invisible hand" and competition. The "invisible hand" refers to the self-regulating nature of the market, where individuals pursuing their own interests inadvertently contribute to the overall economic well-being. Competition, on the other hand, drives innovation and efficiency, ensuring that prices reflect true value and resources are allocated effectively. Together, these factors promote a balanced and efficient marketplace.
