The price level will increase while real GDP decreases when:
aggregate demand decreases/shifts to the left
short-run aggregate supply decreases/shifts to the left
short-run aggregate supply increases/shifts to the right
aggregate demand increases/shifts to the right
When price level increases while GDP decreases when, aggregate demand decreases/shifts to the left. This is so because GDP decreases which leads to a decrease in consumer spending and hence, aggregate demand decreases.
