The IS - LM model is a Keynesian macroeconomic concept which draws relation between Investment Savings and Liquid Money thus showing us the how the economic market for goods and money market. With the consumer spending plummeting during the financial crisis of 2008, IS-LM model could give us a comprehensive overview on the analysis. Now take a look at the figure below
According to prominent Economists, the steep decrease in consumer spending and low confidence in business primarily resulted from financial crisis ( decrease in real personal consumption shows this), led to significant shift towards left of the IS curve in an IS-LM model as shown in the graph above. In the short run, this resulted in an observable decrease in output and had the target interest rate been maintained, the output would have further decreased to Y" as shown in the graph above. Monetary and fiscal policies made a coordinated effort to bring back the economy to life by announcing interest rate cuts for banks, announcing stimulus package and many more.
Now let's analyze the IS-LM curve after substantial policy changes to revive the economy.
One of the vital moves by the Central bank was to reduce real
interest rates. By doing so, it helped stimulate domestic demand
viz the six channels transmission mechanism. For instance, the
Reserve Bank of Australia
(RBA) increased liquidity in the cash market via a plethora of
open-market purchases which helped in lowering the interest rate by
shifting the LM curve downward as shown in the graph above. This
measure counterbalances the leftward shift of the IS curve
previously, and encourages the maintenance of output levels (Y"')
over short run period. Refer to the graph for better
understanding.
Hope this helps. Do hit the thumbs up. Cheers!
