When the economy is at equilibrium in the short run, the following statements can be considered:
-
A natural rate of unemployment exists. - This statement is true. The natural rate of unemployment represents the long-term unemployment rate when the economy is at full capacity, which can be consistent with short-run equilibrium.
-
A negative GDP gap is possible. - This statement is also true. Although the economy can be at short-run equilibrium, it may still be producing below its potential output, leading to a negative GDP gap.
-
Neither a negative nor a positive GDP gap is possible. - This statement is false. As mentioned, at short-run equilibrium, a negative GDP gap is possible.
-
A positive GDP gap is possible. - This statement can also be true in certain circumstances, particularly if the economy is overheating or producing above its potential output, leading to a positive GDP gap.
In summary, the true statements about short-run equilibrium in the economy are that:
- A natural rate of unemployment exists.
- A negative GDP gap is possible.
- A positive GDP gap is also possible, depending on the specific conditions of the economy.
So the true answers are:
- A natural rate of unemployment exists.
- A negative GDP gap is possible.
- A positive GDP gap is possible.
