From a spending model perspective,explain the causes and dynamicsof a recession. consider that we have learned that recessions seem to demonstrate that expenditures and incomes depend on each other.If markets do not self-adjust, consider how a decline in spending can lead to a negative process that ruins an economy. Furthermore, consider implications of spending gaps in the spending models we have studied like the "Keynesian Cross" and the "Aggregate Demand/Aggregate Supply" frameworks. Identify and summarize the market dynamics triggered by changes in leakages and injections. How do measures like GDP, unemployment and inflation play out in the different scenarios based on these spending models? How do propensities and multipliers, and even expectations affect the outcomes in an economic downturn?
