Figure 11.2 Credit and Aggregate Demand
Aggregate Expenditure Credit Volume Less financialized economy More financialized economy
A larger amount of credit disbursed tends to lead to more aggregate demand: Money is usually borrowed by households and firms to finance spending on consumer goods, residential properties or new equipment.
However, the more finalized an economy, the more of the credit goes into non-productive activities without an impact on aggregate demand. For a financialized economy, therefore, the Credit-AE-curve is further to the left.
