The four-firm ratio is the concentration ratio between the total sales accumulated by the four largest industrial firms to the total sales of all firms present in an industry. This translates to the mathematical expression of
four-firm ratio = (total sales of four largest firms / total sales)
Since, we are given that all 10 firms have the same sales, we let the sales be equal to x.
total sales of four largest firms = 4x
total sales = 10x
The ratio is then,
four-firm ratio = 4/10
Converting this to percentage will yield us an answer of 40%.

- Increase in expenditure = $700 billion.
- Marginal propensity to consume = 0.6
The amount of spending based on the information given will be:
= 0.6 × $700 billion

The public debt is the amount of money that a government owes to outside debtors. Public debt allows governments to raise funds to grow their economy or pay for services. Politicians prefer to raise public debt rather than raise taxes. When public debt reaches 77% of GDP or higher, the debt begins to slow growth.
If real GDP is $200 billion, full employment GDP is $400 billion, and the marginal propensity to consume is 0.75, then Congress should-----
increase government purchases by spending by $50 billion.
