Deviation from target capital structure, cost of equity and speed of adjustment

Abstract

In this paper, we analyze the impact of leverage deviation (i.e., actual minus target optimal leverage) on the implied cost of equity capital. Our special focus is on whether (and to what extent) the sensitivity of the cost of equity to leverage deviation, influences the speed with which firms adjust their financial leverage towards the target. Confirming theoretical predictions, we find that the cost of equity is positively related to leverage deviation and that firms whose cost of equity is more sensitive to leverage deviation exhibit faster speed of adjustment towards target. Collectively, our findings imply that capital structure targeting is not equally important to all firms. Indeed, we argue that while evidence of the trade-off theory will tend to be obscured in broad samples, it can hold strongly in meaningfully chosen sub-samples of firms -namely, those characterized by high sensitivity of equity cost to leverage deviation.

Testing capital structure theories using error correction models: Evidence from China, India, and South Africa

“…Yet, there is no clarity on which theory (TOT or POT) can better explain the financing decisions made by a firm (Allini, Rakha, McMillan, & Caldarelli, 2017;Dang, 2013;Mai, Meng, & Ye, 2017;Serrasqueiro & Caetano, 2015). Therefore, there is a need for an integrated framework that incorporates the elements of POT and TOT (Dang & Garrett, 2015;Zhou, Tan, Faff, & Zhu, 2016).…”

Artificial Neural Network to Model Managerial Timing Decision: Non-linear Evidence of Deviation from Target Leverage

“…Arguably, firms are also found to be pursuing equity market timing strategy for in the short-run yet reverting to optimal levels in the long-run [28,44,45]. In addition, firms' deviation from target levels is also influence by its sensitivity to its cost of equity capital where firms with higher cost of equity tend to adjust to target levels at more rapid rates [46]. Firms ability to time the equity market also influences its future growth given that timed issues tend to yield in greater levels of cash and thus providing opportunity for further growth [2].…”

“…Recent studies further indicate that firms deviate from target leverage regularly and the ability to adjust is a function of its cost of Pdf_Folio:1283 equity which is linked to exogenous factors including risk premiums and adjustment costs [46]. Thus, firms with greater levels of variability in changes of equity costs linked to deviation from optimal levels tend to adjust faster leading to an asymmetry in response [45].…”

How do banks implement the capital regulation requirement?

“…Partial adjustment models have been used significantly to analyse the capital structure adjustment (Cook & Tang, 2010;Dang et al, 2014;Zhou et al, 2016) and the capital regulation implementation (Cohen et al, 2014;Shimizu, 2015;Ly et al, 2017;Tung, 2017, Kunitsyna et al, 2018. In which, Cohen et al (2014) suggest that the accumulation of retained earnings, adjustments in lending or assets, adjustments the riskweighted assets, and new equity issued are the strategies that banks used to build capital or to adjust for the capital target achievement.…”
