Federal Funds Rate - shortest term interest rate (overnight), only banks

Causes of Interest Rates

Compound Interest - (1 + r/n)^nt, where n is the number of times compounding per year

Discount Bond

Present Discounted Value: PDV = 1/(1 + r) ^ n ** Important thing to calculate

Conventional Coupon Bond

Forward Rates - interest rates that represent future bond interest rates ???

Inflation and Interest Rates

Leveraging - putting more money in the asset than you have
