Question 1 1 pts In the AS-AD model employed in lectures the short-run aggregate supply (SAS) function slopes upward because O average money wages rise as the aggregate demand for labour increases with aggregate output in the short run O the prices of variable inputs to production increase on average with the greater utilisation of the economy's productive capacity O) average money wages rise as the supply of labour diminishes with the short-run expansion in aggregate output O the marginal productivity of variable inputs to production decline with the greater utilisation of the economy's productive capacity Question 2 1 pts In the AS-AD model, if the actual price level turns out to be less than the expected price level, then O the aggregate demand curve will tend to shift to the left O the short-run aggregate supply curve will tend to shift to the right O the aggregate demand curve will tend to shift to the right O the short-run aggregate supply curve where fe in tend to shift to the left
