The results show that the Jordanian firms are subject to the same determinants of
capital structure as firms in developed markets, namely: profitability, firm size, growth
rate, MB ratio, asset structure and liquidity. In addition, the structure of institutional
ownership was found to be determined by: asset structure, BR, growth opportunities
and firm size. Moreover, the results reveal that asset tangibility, firm size, growth
opportunities and BR are considered to be joint determinants of ownership structure
and capital structure.
