bond buyers do not have any preference about maturity
i.e.
bonds of different maturities are perfect substitutes

then average of ST rates will be >

• if expect ST rates to FALL,
then average of ST rates will be <

• so if true,

UNLESS
LT bonds offer higher yield as incentive
higher yield = liquidity premium

IF LT bond yields have a liquidity premium,
then usually LT yields > ST yields
or yield curve slopes up.

• How do we interpret yield curve?
• slope due to 2 things:
(1) exp. about future ST rates
(2) size of liquidity premium
• do not know size of liq. prem.
