Three essays on capital structure and adjustment speed toward the target leverage of Vietnamese listed firms

Abstract : The first paper stemmed from this thesis seeks to explore the determinants of the capital structure of Vietnamese listed companies, with an emphasis on outside ownership. The empirical results demonstrate that the proportion of state investment has no linear impact on firm leverage. The results, however, reveal an inverted U-shaped relationship. Besides, our empirical results show that the proportions of foreign investment and large holders are negatively associated with short-term, total and market leverage. There is no evidence about the non-linear relationship between foreign and large ownership and the capital structure of observed firms.The second study aims to explore some new aspects of the issue of adjustment speed toward the target leverage for Vietnamese publicly quoted firms by adopting a partial adjustment model. Through testing the existence of the target leverage and estimating the speed of adjustment, the study tries to find evidence of heterogeneity in adjustment behavior. Indeed, the assumption that the speed of adjustment is the same for all firms is inconsistent with the argument of the tradeoff theory which states that firms readjust their leverage by comparing the costs and benefits of adjustment. For different firms, these elements are different, leading to heterogeneity in speed. Even for a single company, the speed could change over time. To have an in-depth overview of the adjustment mechanism, this study goes inside different sub-samples of firms, i.e., above versus below the target; close versus far from the target; deficit versus surplus firms.The last essay belonging to the thesis provides the first ever evidence of the changes of adjustment behaviors over the business life cycle of Vietnam quoted firms from 2005 to 2017. The outcomes show that the adjustment speed towards the target leverage varies significantly across the five phases of life, and reaches the highest level in the stage of introduction. The results also indicate that the cash flow pattern is a more reliable proxy of business life cycle stages than firm age and growth rate. Our empirical evidence supports the pecking order theory as the best-fit framework to understand the funding behavior of Vietnam listed firms throughout corporate life.
