Comprehensive vocabulary flashcards covering the operation of financial markets, institutional roles, interest rate determination via loanable funds theory, and the term structure of interest rates.

Financial Market

A market in which financial assets (securities) such as stocks and bonds can be purchased or sold, transferring funds when one party purchases assets previously held by another party.

Surplus Units

Market participants who receive more money than they spend (such as individual or institutional investors) and supply funds to the financial markets.

Deficit Units

Market participants who spend more money than they receive (such as corporate or government borrowers) and access funds through financial markets.

Money Market Securities

Debt securities that facilitate the transfer of short-term funds from surplus units to deficit units, having a maturity of one year or less.

Capital Market Securities

Long-term financial instruments—including bonds, mortgages, mortgage-backed securities, and stocks—that facilitate the sale of long-term funding by deficit units to surplus units.

Derivative Securities

Financial contracts whose values are derived from the values of underlying assets, used by market participants for speculation or risk management.

Behavioral Finance

The application of psychology to financial decision-making, helping to explain market movements and security pricing behaviors.

Securities Act of 1933

Financial Reform Act of 2010

Legislation (also known as the Wall Street Reform and Consumer Protection Act) that mandated strict verification of mortgage applicant credentials and established the Office of Credit Ratings.

Loanable Funds Theory

A macroeconomic theory suggesting that the market interest rate is determined by factors controlling the supply of and demand for loanable funds.

Household Demand for Loanable Funds

The demand by individuals to finance expenditures such as housing, automobiles, and household goods, which exhibits an inverse relationship with the interest rate.

Interest-Inelastic Demand

Demand for loanable funds that is insensitive to changes in interest rates, characteristically demonstrated by federal government borrowing driven by fiscal policy and budget deficits.

Aggregate Demand for Loanable Funds ($D_A$)

The sum of the quantities of loanable funds demanded across all market sectors at any given interest rate: $D_A = D_h + D_b + D_g + D_m + D_f$.

Aggregate Supply of Loanable Funds ($S_A$)

The total volume of loanable funds supplied across all sectors (principally households) combined with funds injected via Federal Reserve monetary policy: $S_A = S_h + S_b + S_g + S_m + S_f$.

Equilibrium Interest Rate

The specific interest rate at which the aggregate supply of loanable funds perfectly matches the aggregate demand for loanable funds ($S_A = D_A$).

Fisher Effect

The relationship stating that the nominal or quoted interest rate ($i$) equals the expected inflation rate ($E(INF)$) plus the real interest rate ($i_R$): $i = E(INF) + i_R$.

Crowding-Out Effect

The market phenomenon where heavy federal government borrowing consumes a large share of available loanable funds, thereby crowding out private borrower demand.

Net Demand for Loanable Funds ($ND$)

The forecast difference between the aggregate demand for loanable funds and the aggregate supply of loanable funds: $ND = D_A - S_A$.

Credit (Default) Risk

The risk that a debt security issuer will fail to meet scheduled contractual interest or principal payments, requiring higher yields to compensate investors.

Credit Rating Agencies

Independent commercial agencies that assess the default risk of debt security issuers for a fee, providing risk opinions rather than investment guarantees.

Office of Credit Ratings

A regulatory division established within the Securities and Exchange Commission (SEC) by the Financial Reform Act of 2010 to regulate and inspect credit rating agency practices.

Equivalent Before-Tax Yield

The before-tax yield ($\gamma_{bt}$) that a taxable debt security must offer to match an after-tax yield ($\gamma_{at}$) given an investor's marginal tax rate ($T$): $\gamma_{bt} = \frac{\gamma_{at}}{(1 - T)}$.

Term Structure of Interest Rates

The relationship that defines how annualized yields on debt securities vary according to differences in their terms to maturity.

Yield Differential

The difference between the yield offered on a specific debt security and the yield offered on a default-free (Treasury) security of matching maturity.

Basis Point

A standardized financial unit of measurement equal to one one-hundredth of a percent ($1\,\text{bp} = 0.01\%$), commonly used to express yield spreads.

Appropriate Yield Model

A framework for estimating the yield on an $n$-day debt security ($Y_n$): $Y_n = R_{f,n} + DP + LP + TA$, where $R_{f,n}$ is the risk-free rate, $DP$ is the default premium, $LP$ is the liquidity premium, and $TA$ is the tax adjustment.

Pure Expectations Theory

A theory of the term structure proposing that the shape of the yield curve is determined solely by overall market expectations of future interest rates.

Liquidity Premium Theory

A term structure theory asserting that investors prefer short-term liquid securities and require an additional yield premium to hold longer-term debt obligations.

Segmented Markets Theory

A term structure theory stating that investors and borrowers operate within rigid maturity segments dictated by their planned cash flow horizons, preventing substitution between short and long maturities.

Preferred Habitat Theory

A modification of segmented markets theory suggesting that although participants prefer operating in a natural maturity habitat, attractive yield differentials can induce them to shift across maturities.
