This thesis analyzes real oil price crises and US output gap by using time frequency representation. Firstly, time frequency representation is introduced by giving some basic definitions, formulations and illustrative examples. After that, frequency characteristics of demand-side driven and supply-side driven real oil price shocks are analyzed. Also, frequency characteristic of US output gap is analyzed by dividing the output gap series in three parts.
