Say that investment increases by 20 for each interest rate drop of 1 percent. Say also that the expenditures multiplier is 3 . If the money multiplier is 4 , and each 5 unit change in the money supply changes the interest rate by 1 percent, what open market policy would you recommend to increase income by 240? $\mathrm{LO1}, \mathrm{LO} 4$

Key Concepts

Money Multiplier

The money multiplier captures the process by which an initial injection of reserves into the banking system leads to a more than proportional increase in the overall money supply. This effect arises from the fractional-reserve banking system where banks lend out part of their deposits, thereby creating new money through repeated cycles of re-depositing and re-lending.

Open Market Operations

Open market operations are tools used by central banks to control the money supply and influence interest rates by buying or selling government securities. These operations are central to implementing monetary policy, as they help the central bank adjust liquidity in the financial system to achieve economic objectives such as controlling inflation or stimulating economic growth.

Interest Rate and Investment Relationship

This concept explains that changes in interest rates have a direct impact on investment levels. Specifically, a decrease in interest rates lowers the cost of borrowing, making it more attractive for firms to invest in new projects or expansion, thereby stimulating economic activity.

Expenditure Multiplier

The expenditure multiplier measures how an initial change in spending leads to a greater overall change in national income. This effect occurs because the first round of spending creates income for others, which then spurs further spending in successive rounds, amplifying the original impact on the economy.
