Abstract:
One of the most debated topics in corporate finance is capital structure, which requires consideration in order to enable financial managers to make effective investment decisions. Capital
structure consists mainly of debt and equity of a firm. When choosing a company’s capital
structure, different factors must be taken into account in order to optimize the profitability and
value of a firm. This research intends to critically assess literature on determinants of capital
structure of a firm. The sources of finance, however, are clearly affected by some major factors
such as taxes, information asymmetry, and agency cost. Interpretations of these factors differ
in different theories of capital structure as they are not proposed to be general as some focus
on cost and other focus on benefits from different sources of funding. The literature also points
out that behavioral biases such as overconfidence, optimism, loss aversion and anchoring lead
to the fact that managers of the companies form the capital structure on the basis of their own
affinities. In addition, based on literature analysis, each firm has different specific factors such
as profitability, firm size, tangibility, liquidity, depreciation, growth opportunity, and business
risk related to capital structure; also, a firms better management understands the dynamics of ´
interest rate, inflation, and economic growth. Most of the literature on the determinants of capital structure neglected to bring the capital market circumstances into the inquiry and achieved a
result relying on either quantitative or qualitative methods. Existing literature on determinants
of capital structure can be examined from a point of view in different influences of theories,
behavior, firm, economic and capital market conditions and also the research to be carried out
together with quantitative and qualitative methods will be an introduction of new knowledge to
the literature on the determinants of capital structure.
