Question

Price not only gives incentives, but it also provides a convenient way to summarize information to decision makers with regards to wants and _______.

Answer 1

The decision makers here are for example the people who are potential producers, so if I wander what I want to produce, it look at the prize. If it's high, it means that people want it a lot but that it's not easily available (the answer here is "availability) - which means that if I make more, i will reduce the prize but still make some profit
