Saving, Investment, and the Financial System Chapter 26

Financial Institutions For investment to take place an economy needs a healthy financial system. The financial system: the group of institutions that helps match the saving of one person with the investment of another. When people save or invest their money, their funds become available for businesses to use to expand and grow. In this way, investment promotes economic growth for the entire economy. Financial institutions: financial markets and financial intermediaries SAVING, INVESTMENT, AND THE FINANCIAL SYSTEM 1

Financial Institutions Financial markets: Institutions through which savers can directly provide funds to borrowers. Examples: The Bond Market. (Debt finance) A bond is a certificate of indebtedness. (IOU) Components of a bond Investment considerations Types of bonds Bond ratings The Stock Market. (Equity Finance) A stock is a claim to partial ownership in a firm. Exchanges Capital Gains/Dividends SAVING, INVESTMENT, AND THE FINANCIAL SYSTEM

Financial Institutions Financial intermediaries: institutions through which savers can indirectly provide funds to borrowers. Examples: Banks- Commercial Banks- Provide the most services. They provide services to individuals and businesses. Savings and Loan Associations- Traditionally accepted deposits and offered long term loans. Savings Banks- Accept deposits and offer low-risk investments. Credit Unions- Non-profit banks owned by their members. Mutual funds – institutions that sell shares to the public and use the proceeds to buy portfolios of stocks and bonds. SAVING, INVESTMENT, AND THE FINANCIAL SYSTEM 3

Different Kinds of Saving Private saving = The portion of households’ income that is not used for consumption or paying taxes = Y – T – C Public saving = Tax revenue less government spending = T – G SAVING, INVESTMENT, AND THE FINANCIAL SYSTEM 4

National Saving = private saving + public saving = (Y – T – C) + (T – G) = Y – C – G = the portion of national income that is not used for consumption or government purchases SAVING, INVESTMENT, AND THE FINANCIAL SYSTEM 5

Budget Deficits and Surpluses Budget surplus = an excess of tax revenue over govt spending = T – G = + = public saving Budget deficit = a shortfall of tax revenue from govt spending = T – G = - = – (public saving) SAVING, INVESTMENT, AND THE FINANCIAL SYSTEM 6

The Meaning of Saving and Investment Private saving is the income remaining after households pay their taxes and pay for consumption. Buy corporate bonds or equities Purchase a certificate of deposit at the bank Let money accumulate in saving or checking accounts Investment is the purchase of new capital. General Motors spends $250 million to build a new factory in Flint, Michigan. You buy $5000 worth of computer equipment for your business. Your parents spend $300,000 to have a new house built. SAVING, INVESTMENT, AND THE FINANCIAL SYSTEM 7

The Market for Loanable Funds A supply-demand model of the financial system Assume: only one financial market All savers deposit their saving in this market. All borrowers take out loans from this market. There is one interest rate, which is both the return to saving and the cost of borrowing. The supply of loanable funds comes from private and public savings. The demand for loanable funds comes from private and business investment. SAVING, INVESTMENT, AND THE FINANCIAL SYSTEM 8

The Slope of the Supply Curve An increase in the interest rate makes saving more attractive, which increases the quantity of loanable funds supplied. Interest Rate Loanable Funds ($billions) Supply 80 6% 60 3% SAVING, INVESTMENT, AND THE FINANCIAL SYSTEM 9

The Slope of the Demand Curve A fall in the interest rate reduces the cost of borrowing, which increases the quantity of loanable funds demanded. Interest Rate Loanable Funds ($billions) Demand 50 7% 4% 80 SAVING, INVESTMENT, AND THE FINANCIAL SYSTEM 10

Equilibrium The interest rate adjusts to equate supply and demand. Loanable Funds ($billions) Supply Demand The eq’m quantity of L.F. equals eq’m investment and eq’m saving. 5% 60 SAVING, INVESTMENT, AND THE FINANCIAL SYSTEM 11

Policy 1: Saving Incentives Tax incentives for saving increase the supply of L.F. Interest Rate S1 S2 …which reduces the eq’m interest rate 5% 4% and increases the eq’m quantity of L.F. 70 D1 60 Loanable Funds ($billions) SAVING, INVESTMENT, AND THE FINANCIAL SYSTEM 12

Policy 2: Investment Incentives An investment tax credit increases the demand for L.F. Interest Rate D2 S1 6% 70 …which raises the eq’m interest rate 5% and increases the eq’m quantity of L.F. As with Policy 1, you may wish to note that we are assuming the tax credit does not significantly reduce the overall amount of taxes. If total taxes fell, then the supply curve would shift (in addition to the demand curve). However, our intention here is to focus solely on the demand shift.

Budget Deficits, Crowding Out, and Long-Run Growth Increase in budget deficit causes fall in investment. The crowding out effect- The government borrows to finance its deficit, leaving less funds available for investment. The government finances deficits by borrowing (selling government bonds). Persistent deficits lead to a rising government debt. The ratio of government debt to GDP is a useful measure of the government’s indebtedness relative to its ability to raise tax revenue. Historically, the debt-GDP ratio usually rises during wartime and falls during peacetime – until the early 1980s. SAVING, INVESTMENT, AND THE FINANCIAL SYSTEM 14

CONCLUSION Like many other markets, financial markets are governed by the forces of supply and demand. One of the Ten Principles from Chapter 1: Markets are usually a good way to organize economic activity. Financial markets help allocate the economy’s scarce resources to their most efficient uses. Financial markets also link the present to the future: They enable savers to convert current income into future purchasing power, and borrowers to acquire capital to produce goods and services in the future. SAVING, INVESTMENT, AND THE FINANCIAL SYSTEM

Chapter Summary The U.S. financial system is made up of many types of financial institutions, like the stock and bond markets, banks, and mutual funds. National saving equals private saving plus public saving. In a closed economy, national saving equals investment. The financial system makes this happen. The supply of loanable funds comes from saving. The demand for funds comes from investment. The interest rate adjusts to balance supply and demand in the loanable funds market. A government budget deficit is negative public saving, so it reduces national saving, the supply of funds available to finance investment. When a budget deficit crowds out investment, it reduces the growth of productivity and GDP. 17
