Explain the term inflationary gap and deflationary

When we look at the Keynes theory of income e and employment we came to know that the level of income and employment is determined where AD= AS. But such equilibrium level of NI does not necessarily represent full employment. According to Keynes:

The equilibrium level of NI may be at full employment. This situation occurs when at the level of full employment maximum level of NI permitted by the utilization of the entire human and natural resources of the economy aggregate demand is equal to aggregate supply.

The equilibrium level of NI may be at above full employment. This situation occurs when at the level of full employment aggregate demand is greater than aggregate supply. This situation corresponds to inflationary gap.The equilibrium level of NI may be at below full employment. This situation occurs when at the level of full employment aggregate demand is less than aggregate supply. This situation depicts deflationary gap.

With such brief review of inflationary and deflationary gaps, we move to explain these concepts, in addition to Keynes Ad and AS curves we will also modern AD and AS curves where we established relationship between price level and AD, price level and AS.

So in the equilibrium level AD= AS.

The equilibrium level of NI may be at full employment. This situation occurs when at the level of full employment maximum level of NI permitted by the utilization of the entire human and natural resources of the economy aggregate demand is equal to aggregate supply.

The equilibrium level of NI may be at above full employment. This situation occurs when at the level of full employment aggregate demand is greater than aggregate supply.

So in the equilibrium level AD= AS.
