What are the basic ideas of Adam Smith and how do they shape modern economic theory?

Adam Smith's basic ideas revolve around the concept of free markets and the invisible hand. He believed that individuals pursuing their own self-interest would unintentionally benefit society as a whole. This idea has shaped modern economic theory by influencing the development of capitalism and the belief in minimal government intervention in markets. Smith's ideas have also contributed to the understanding of how markets work and the importance of competition in driving economic growth.
