<span>The marginal propensity to consume is a metric
that quantifies the concept of increase in consumption with an increase in
income. Mathematically MPC is defined as:</span>
MPC = Change in consumption / Change in income
Purchase of goods and services is considered as
consumption, therefore:
Change in consumption = $16 billion
In the government’s perspective, taxes are
considered as income, therefore the problem ask us to find for the necessary change
in tax collection to maintain equilibrium GDP. Substituting the values in the
formula:
0.80 = $16 billion / Change in income
Change in income = $20 billion
<span>Therefore the government should increase the tax collection by $20
billion.</span>
 
        
                    
             
        
        
        
The preferred stock effect is not a notion that can be used to explain abnormally high excess stock returns.
<h3>What is the preferred stock?</h3>
The term "stock" refers to a company's ownership or equity. Common stock and preferred stock are the two forms of equity. Preferred investors are entitled to more dividends or asset distributions than common stockholders. The specifics of each preferred stock vary depending on the issuance.
When it comes to dividends, preferred stockholders have a preference over ordinary stockholders, which typically yield more than common shares and might be paid monthly or quarterly. These dividends can be fixed or determined by reference to a benchmark interest rate, such as the London Interbank Offered Rate.
