Question

multiple - choice question
what are price signals?
when producers tell each other what price they are selling goods for
information generated by markets to guide distribution of resources
information in shops about the price of goods

Explanation:

Price signals are information generated by markets. They play a crucial role in guiding the distribution of resources. When prices change, it indicates changes in supply and demand. For example, if the price of a good rises, it signals to producers that there is more demand, so they may increase production (allocating more resources to produce that good). It's not just producers telling each other prices (which is more like communication between a specific group rather than the market - wide signal) and not just shop - specific price information (as it's about the overall market mechanism).

Answer:

Information generated by markets to guide distribution of resources
