Solution by Steps
step 1
To understand the impact of increased savings on the interest rate, we consider the supply and demand model for loanable funds. An increase in savings shifts the supply curve for loanable funds to the right
step 2
According to the law of demand, an increase in the supply of loanable funds, with demand remaining constant, leads to a decrease in the equilibrium interest rate
step 3
A decrease in the interest rate reduces the cost of borrowing, which can encourage investment and potentially increase the long-run aggregate supply (LRAS) as the economy's productive capacity expands
Answer
A
Key Concept
Loanable Funds Market and LRAS
Explanation
