Some characteristics of the determinants of nominal interest rates are listed as follows. Identify the components (determinants) and the symbols associated with each characteristic: Characteristic Component Symbol This is the premium added to the risk-free rate that reflects the average sustained increase in the general level of prices for goods and services expected over the security's entire life. Inflation premium Default risk premium This premium is added when a security lacks marketability, because it cannot be bought and sold quickly without losing value.
