The empirical study is performed using the time series data of the U.S. between the years 1950 and 2007. The findings reveal that personal saving is highly dependent on personal income, tax, credit outstanding and status of employment, while dependency ratio, current real estate loan, real interest rate and status of economic performance are indeterminate.<em><span style="mso-bidi-font-style: normal;"></span></em></span></span></p>
