we explored the relationship between term-to-maturity and yield-to-maturity. We noted the following observations:

1) Yield curvesmayslope upwards, downwards, or be flat.

2) Interest rates of different maturities tend to move together.

3) Yield curves historically tend to slope upward.

Do you think that the "Augmented Expectations Theory" (also known as "Liquidity Premium Theory") is consistent with all 3 observations above?
