Suppose the government borrows $\$$20 billion more next year than this year. a. Use a supply-and-demand diagram to analyze this policy. Does the interest rate rise or fall? b. What happens to investment? To private saving? To public saving? To national saving? Compare the size of the changes to the $\$$20 billion of extra government borrowing. c. How does the elasticity of supply of loanable funds affect the size of these changes? d. How does the elasticity of demand for loanable funds affect the size of these changes? e. Suppose households believe that greater government borrowing today implies higher taxes to pay off the government debt in the future. What does this belief do to private saving and the supply of loanable funds today? Does it increase or decrease the effects you discussed in parts (a) and (b)?

Key Concepts

Loanable Funds Market

The loanable funds market is a conceptual framework used to analyze the interaction between savers and borrowers. In this market, the supply of funds typically comes from household savings, while the demand comes from entities that require funds for investment and government borrowing. This model helps explain how interest rates are determined by the intersection of the supply and demand curves for funds, and how shifts in either can affect the overall allocation of resources in an economy.

Interest Rate Determination

Interest rate determination is central to the loanable funds market, as it represents the equilibrium price at which borrowing equals saving. When there is an increase in demand for funds, such as through additional government borrowing, the equilibrium interest rate tends to rise. This higher interest rate then influences various economic activities, including private investment and savings behavior.

Government Borrowing and Crowding Out

Government borrowing affects the loanable funds market by increasing the demand for funds. This can lead to a 'crowding out' effect, where higher interest rates discourage private investment by raising the cost of borrowing for businesses and households. The crowding out effect highlights the trade-off between public and private sector borrowing and its potential impact on economic growth.

Elasticity of Loanable Funds Supply and Demand

The elasticity of supply and demand in the loanable funds market measures how responsive the quantity of funds supplied or demanded is to changes in the interest rate. A relatively inelastic supply implies that changes in interest rates lead to only small changes in the amount of saving, while an inelastic demand implies that investment is less sensitive to interest rate fluctuations. These elasticities determine the magnitude of changes in interest rates and investment in response to shifts in government borrowing.

Public Saving

Public saving refers to the portion of government revenue that is not spent on public expenditures. It is calculated as the difference between tax receipts and government spending. An increase in government borrowing typically indicates lower public saving, as the government finances a larger portion of its expenditure by borrowing, thereby reducing the overall national saving.

Private and National Saving

Private saving is the saving that households accumulate from their disposable income, and it constitutes a major part of the supply of funds in the loanable funds market. National saving is the sum of private saving and public saving. Changes in government borrowing can affect national saving both directly, by altering public saving, and indirectly, through changes in private saving if households adjust their saving behavior in anticipation of future budgetary changes.

Government Debt Expectations and Ricardian Equivalence

Government debt expectations refer to the beliefs held by households regarding the future implications of current government borrowing, such as higher taxes to repay debt. According to the Ricardian Equivalence hypothesis, if households foresee future tax increases due to current borrowing, they may increase their private saving to offset anticipated future tax burdens. This concept is critical in understanding how fiscal policy and government borrowing decisions can alter saving behavior and affect the overall supply of loanable funds in the present.
