Capital structure and firm value: the role of contextual variables in this relationship

This study aims to identify the role of contextual variables, especially the interest rate, in affecting the relationship between a firm’s capital structure and firm value. This study investigates the capital structure of Pakistani-listed firms in light of rising interest rates, declining “Domestic credit to the private sector” and emerging Islamic banking in the country. The study uses GMM (Two-Step) to examine the linear, and dynamic Panel threshold model to examine the quadratic relationship between leverage firm value and how other contextual variables affect this relationship. The study found that there is a negative relationship between leverage and firm value in the presence of the majority of contextual variables. Except for tax, depreciation, and free cash flow, leverage shows a negative relationship with firm value in presence of all other contextual variables. Further results show that there is a quadratic relationship present between leverage and firm value. Also, the interest rate and inflation has a negative effect on firm value in long term, while in short term this relationship is positive. The study supports the pecking order & Trade-off theory but does not support the agency theory. The study is using new methodologies, just as the panel threshold model which is never used before for Pakistani industries. The panel threshold model is using some variables for the first time in research. Previously only size and debt were used in panel threshold models, this time we used debt, firm value, profitability, tax, and tangibility, which will be a significant contribution to the literature.
