Abstract
According to trade off theory, firms determine optimal capital structure for themselves, but usually deviate from this target capital structure, so they need to adjust this deviation. This research tries to analyze the impact of structure change of 2012 and exchange rate increase as an index of macroeconomic variable on speed of adjustment of capital structure among firms were accepted in Tehran Stock Exchange. The data of 124 firms were collected in period of 2005-2014 and partial adjustment model was used. Results of researches hypothesis show that firms with bigger size, higher growth opportunities, higher earning volatility, less age and less deviation from target leverage adjust their capital structure with higher speed than firms with contrasting features. Moreover, structure change of 2012 and exchange rate increase as a macroeconomic index can decrease the speed of adjustment.
