Determinants of Capital Structure : A study of Swedish companies

Abstract: The choice of a corporation’s capital structure is a complex process determined by several factors. The academia and the business industry have both been enamored with finding the determinants of capital structure, as there has been evidence that the profitability of firms is influenced by financing decisions. Nevertheless, the determinants are so far inconclusive. Moreover, they are dependent on both internal and external factors. However, previous research has generally focused solely on internal or external factors. Therefore, this thesis aims to capture a combination of firm-specific factors and macroeconomic variables affecting capital structure decisions. We focus on Swedish firms listed on Nasdaq OMX. To investigate which internal and external factors affect the capital structure, an unbalanced fixed effects data multiple linear regression was performed. The regression tested several hypotheses derived from previous studies, where the trade-off theory and the pecking order theory were used as a base. Our results indicate that for internal factors, the pecking order theory is superior at explaining financial decisions in Swedish companies compared to the trade-off theory. When it comes to external factors, the pecking order theory provides a more accurate framework. However, it should be noted that the results are not unambiguous. The ambiguity of the results suggests one very important conclusion. Neither of these two theories have the capability to fully explain how firms decide their capital structure. Each model contributes with some pieces of the puzzle, but both contain limitations.
