soldier1979 [14.2K]

The given question is incomplete as the group of choices are not given, required to answer the question. However, the group of choices for this question is as follows:

1) stable – if we are there we will stay there, unless outside forces change

2)  unique – there is one and only one equilibrium, a property which follows from the “Law of Demand” and “Law of Supply”

3)  self-enforcing – at higher prices there is downward pressure on price; at lower prices there is upward pressure on price – therefore if we are at some other price, we will be pushed toward the equilibrium price

4)  All of the above statements are correct

Answer:

The correct answer is - option 4. all of the above statements are correct.

Thus, the correct answer is - option 4. all of the statements are correct
