Practical models consider Georgia’s economic specification and important events (results of the war in august, 2008 year).

Also, research estimates quarterly values of Georgia’s total capital from 2003 year to 2016 year and depreciation rate, which is equal to 5.7%. Last part of the article presents comparative analysis of empirically tested models in case of Georgia and USA.
