Asymmetric adjustment toward optimal capital structure: Evidence from a crisis

We employ dynamic threshold partial adjustment models to study the asymmetries in firms' adjustments toward their target leverage. Using a sample of US firms over the period 2002–2012, we document a negative impact of the Global Financial Crisis on the speed of leverage adjustment. In our subperiod analysis, we find moderate evidence of cross-sectional heterogeneity in this speed, which seems more pronounced pre-crisis and provides little support for the financial constraint view. Over the pre-crisis period, more constrained firms, such as those with high growth, with large investment, of small size, and with volatile earnings, adjust their capital structures more quickly than their less constrained counterparts. These firms rely heavily on external funds to offset large financing deficits, suggesting that their higher adjustment speeds may be driven by lower adjustment costs that are shared with the transaction costs of accessing external capital markets. During the crisis, the speed of adjustment varies with the deviation from target leverage: only firms with sufficiently large deviations attempt to revert to the target, albeit slowly. Overall, our results provide new evidence of both cross-sectional and time-varying asymmetries in capital structure adjustments, which is consistent with the trade-off theory.     

How and When Do Firms Adjust Their Capital Structures toward Targets?

If firms adjust their capital structures toward targets, and if there are adverse selection costs associated with asymmetric information, how and when do firms adjust their capital structures? We suggest a financing needs‐induced adjustment framework to examine the dynamic process by which firms adjust their capital structures. We find that most adjustments occur when firms have above‐target (below‐target) debt with a financial surplus (deficit). These results suggest that firms move toward the target capital structure when they face a financial deficit/surplus—but not in the manner hypothesized by the traditional pecking order theory.     

Do Firms Rebalance Their Capital Structures?

We empirically examine whether firms engage in a dynamic rebalancing of their capital structures while allowing for costly adjustment. We begin by showing that the presence of adjustment costs has significant implications for corporate financial policy and the interpretation of previous empirical results. After confirming that financing behavior is consistent with the presence of adjustment costs, we find that firms actively rebalance their leverage to stay within an optimal range. Our evidence suggests that the persistent effect of shocks on leverage observed in previous studies is more likely due to adjustment costs than indifference toward capital structure.     

Macroeconomic conditions and capital structure adjustment speed

Using two dynamic partial adjustment capital structure models to estimate the impact of several macroeconomic factors on the speed of capital structure adjustment toward target leverage, we find evidence that firms adjust their leverage toward target faster in good macroeconomic states relative to bad states. This evidence holds whether or not firms are subject to financial constraints. Our results are robust to an alternative method of calculating states and to omitting zero-debt boundary firms and are not driven by firm size, deviation from target, or leverage definitions.     

The effect of corporate sustainability performance on leverage adjustments

We examine the impact of corporate sustainability performance (CSP) on the speed at which firms adjust their leverage ratios to the target levels for a large sample of 31 countries from 2002 to 2018. Using two proxies of CSP, we find that firms with superior CSP tend to adjust faster toward their target leverage ratios. In exploring the potential underlying economic mechanisms through which CSP affects leverage adjustments, we find that better CSP helps firms to ease information asymmetry, enhance stakeholder engagement, push up stock prices in the stock market, and improve competitive advantage in the product market. In the cross section, the positive association between CSP and leverage adjustment speed is less pronounced in countries with high-quality institutions. The results remain unchanged in robustness tests. Overall, this paper highlights the important role of CSP in shaping corporate capital structure dynamics and suggests implications for corporate strategic planning on the privately optimal levels of CSP activities.     

Incorporating active adjustment into a financing based model of capital structure

The conventional partial adjustment model, which focuses on leverage evolution, has difficulty identifying deliberate capital structure adjustments as it confounds financing decisions with the mechanical autocorrelation of leverage. We propose and estimate a financing-based partial adjustment model that separates the effects of financing decisions on leverage evolution from mechanical evolution. The speed of adjustment (SOA) is firm-specific and stochastic, and active targeting of capital structure has a multiplier effect that depends on the size of financial deficit. Overall, we find expected SOA from active rebalancing (30%) more than doubles what is expected from mechanical mean reversion alone (13%).     

产业政策与企业资本结构调整速度

本文以2006-2015年我国沪深A股上市公司为研究样本,在“十一五”与“十二五”产业规划所处的时间区间内,考察了产业政策对企业资本结构调整速度的影响以及作用路径。结果显示,产业政策与企业资本结构调整速度显著正相关,且分别在非国有、小规模和融资约束较严重的企业中更加显著。区分调整方向后发现,产业政策能提高资本结构向上调整的速度,但只有重点产业政策能提高固定资产比例较低的企业向下调整的速度。基于作用路径的分析发现,产业政策提高了企业选择增加债务的方式来调整资本结构的概率;重点产业政策提高了特定类型企业以增加权益方式向下调整资本结构的概率。上述结果表明,产业政策主要通过债务融资方式影响资本结构调整速度,而只有受到重点产业政策支持的特定类型的企业能够通过权益融资方式提高资本结构调整速度。     

Local social environment and the speed of leverage adjustment

This study examines the impact of social capital on firms’ leverage adjustment speed. Using a comprehensive dataset of 83,374 firm-year observations for 744 US counties for 1990–2016, we find that both underleveraged and overleveraged firms located in US counties with higher levels of social capital incur slower leverage adjustment towards their optimal target capital structure. This finding is robust to alternative measures of leverage and social capital, different model specifications, controlling for county- and firm-level characteristics, and endogeneity. We further identify two mechanisms through which social capital affects leverage adjustments: monitoring (channel for underleveraged firms) and disciplinary (channel for overleveraged firms) mechanisms.     

Ultimate Ownership and Adjustment Speed Toward Target Capital Structures: Evidence from China

We investigate whether ultimate ownership affects firms’ adjustment speed toward target capital structures for Chinese publicly listed companies over the period 1999–2009. We divide our sample into state-owned enterprises (SOEs) and non-SOEs according to their ultimate ownership. We find that SOEs have higher leverage ratios and slower adjustment speeds toward target capital structures. Our results are consistent with the trade-off theory, implying that the political resources of SOEs can lead to a higher persistence and slower leverage adjustment speeds in comparison to non-SOEs. Finally, our results also raise a question: Why do Chinese companies adjust their capital structure so fast?     

Capital structure and large investment projects

This paper provides empirical evidence that lumpy investment projects provide firms with the opportunity to adjust leverage at low marginal cost. Consistent with a theoretical model, I find that 1) firms sequence equity before debt during the financing period of their investment projects, and 2) that firms adjust their leverage ratios toward their target leverage during these investment periods. I also show that proactive increases in leverage observed in other studies can be explained by the evolution of firms' target leverage ratios over the financing period of a project. My results are consistent with trade-off theory and imply that firms move toward their target capital structures when they invest.     

Corporate governance and the dynamics of capital structure: New evidence

The effects of corporate governance on optimal capital structure choices have been well documented, though without offering empirical evidence about the impact of corporate governance quality on the adjustment speed toward an optimal capital structure. This study simultaneously considers two effects of debt originating from agency theory—the takeover defense and the disciplinary effects of debt—on the speed of adjustment to the optimal capital structure. Corporate governance has a distinct effect on the speed of capital structure adjustment: weak governance firms that are underlevered tend to adjust slowly to the optimal capital structure, because the costs of the disciplinary role of debt outweigh the benefits of using debt as a takeover defense tool. Although overlevered weak governance firms also adjust slowly, they do so because they are reluctant to decrease their leverage toward the target level to deter potential raiders, especially if they face a serious takeover threat. Therefore, this study finds that both overlevered and underlevered firms with weak governance adjust slowly toward their target debt levels, though with different motivations.     

Economic policy uncertainty and leverage dynamics: Evidence from an emerging economy

We test capital structure adjustments under dynamic trade-off theory using the standard partial adjustment framework, in light of long- and short-run economic policy uncertainties (EPU). Analysing a sample of Indian firms listed on the National Stock Exchange (NSE500) for 2009 to 2018, we report a positive association between EPU and leverage but a negative association between EPU and speed of adjustment. An additional analysis indicates that the positive influence of long-run policy shocks on leverage is channelled through the growth prospects available to them. The leverage of firms in industries that are more sensitive to government subsidies reports a stronger positive association between the two variables both in the long and short run. Also, analysis using the suppliers of credit emphasizes that the increase in cost of debt drives the positive association between EPU and leverage for Indian firms. By delving into the mechanisms that impact the association between EPU and speed of adjustment, we find that the negative impact of EPU on leverage adjustments is moderated through the change in investments and the cost of debt only in the long run. The group affiliated firms display a strong positive association between EPU and leverage but a stronger negative association between EPU and speed of adjustment. Our results are robust across alternative measures of EPU, leverage, technique vis-à-vis endogeneity, large sample (4165 listed Indian companies) and heterogeneities based on firm size.     

Capital structure of Islamic banks: How different are they from conventional banks?

This paper uses comprehensive data for 112 Islamic and 709 conventional banks from 23 countries over 1995–2015 to compare the capital structure of Islamic banks (IBs) and conventional banks (CBs) from several perspectives. We find that IBs and CBs seem to face different cost pressures in the process of adjusting towards the target capital structure. Asset growth is a key driver of capital structure change, and CBs adjust leverage more aggressively in response to changes in total assets compared to IBs, because they have an advantage in obtaining external funds and can achieve leverage adjustments faster and at a low cost. IBs have more regulatory capital, but their ability to respond to risks is weaker than traditional banks. The results of this paper suggest that Islamic banks are in a disadvantaged position compared to CBs in capital structure management. The conclusion suggests that IBs need to expand its financing tools and funding sources to reduce adjustment costs and improve their capability to deal with asset risk.     

Employment protection and leverage adjustment speed: Evidence from China

Stricter employment protection may affect capital structure adjustment speed in two ways. First, it may increase the cost of capital and decrease the leverage adjustment speed. Second, it increases financing needs and capital adjustment speed. Using China's 2008 Labor Contract Law as a natural experiment and the PSM-DID methodology, we find that the latter effect dominates the former. Specifically, stricter employment protection increases leverage adjustment speed, and this effect is more pronounced for non-state-owned firms and firms with larger leverage deviations. Furthermore, transmission channel tests show that employment protection increases firms’ substitution of labor with capital, driving up investment and financing needs. Finally, the increased leverage adjustment speed induced by enhanced employment protection is beneficial to firm performance.     

Market Imperfections,Macroeconomic Conditions,and Capital Structure Dynamics: A Cross-Country Study

This article investigates how “systematic” adjustment costs proxied by market imperfections, and macroeconomic conditions affect capital structure dynamics in a cross-country setting. We document substantial variations in firms’ capital structure adjustments across countries and, particularly, over time. Consistent with adjustment costs impeding firms from rebalancing their capital structures, worse market imperfections are associated with slower speeds of adjustment (SOA) and larger leverage deviations. Intertemporally, capital structure adjustment is procyclical, with SOA increasing by 0.9 percentage point for a one-percentage-point increase in GDP growth rate. The procyclicality is attributable to good macroeconomic conditions mitigating market imperfections through channels of 1) facilitating free-ride restructuring and 2) uncertainty alleviation. Our investigation features a bootstrapping-based estimation method that addresses the mechanical mean reversion of leverage ratio.     

中国上市公司资本结构的长期动态调整

本文基于资本结构理论和实证研究的最新成果,构建一个综合反映影响公司资本结构决策各种因素的模型,通过两阶段回归,刻画我国上市公司资本结构长期动态调整的轨迹。我们首先利用Tobit模型预测公司目标资本结构,然后利用局部调整模型综合检验公司资金缺口、市场时机、股价变化、目标缺口和目标资本结构变化如何影响公司资本结构的动态调整。研究发现资金缺口、市场时机和股价变化确实导致公司偏离目标资本结构,其中,资金缺口的影响最大。但是,它们在随后阶段产生了反转效应。实证结果表明,尽管公司的历史显著地影响了它们的资本结构,但经过一段时间,公司的资本结构会趋近于其动态的目标资本结构,公司资本结构变化的决定性因素是目标资本结构。     

The role of credit ratings on capital structure and its speed of adjustment: an international study

Using an international dataset, we examine the role of issuers’ credit ratings in explaining corporate leverage and the speed with which firms adjust toward their optimal level of leverage. We find that, in countries with a more market-oriented financial system, the impact of credit ratings on firms’ capital structure is more significant and that firms with a poorer credit rating adjust more rapidly. Furthermore, our results show some striking differences in the speed of adjusting capital structure between firms rated as speculative and investment grade, with the former adjusting much more rapidly. As hypothesized, those differences are statistically significant only for firms based in a more market-oriented economy.     

Corporate tax,capital structure,and the accessibility of bank loans: Evidence from China

In this paper, we investigate whether listed firms in China adjust their capital structure in response to an increase in the corporate tax rate. Although theories of capital structure suggest that corporate tax is an important determinant of capital structure, how exogenous changes of the tax rate affect firms’ leverage decisions has not been fully explored. We examine a unique circumstance in which the Chinese government increased the corporate tax rate of firms that had previously received local government tax rebates. The evidence indicates that these firms increased their leverage when the corporate tax rate increased. Further investigation suggests that the adjustment of leverage was mostly driven by firms with a high level of access to bank loans.     

Cash flows and leverage adjustments

Recent research has emphasized the impact of transaction costs on firm leverage adjustments. We recognize that cashflow realizations can provide opportunities to adjust leverage at relatively low marginal cost. We find that a firm's cashflow features affect not only the leverage target, but also the speed of adjustment toward that target. Heterogeneity in adjustment speeds is driven by an economically meaningful concept: adjustment costs. Accounting for this fact produces adjustment speeds that are significantly faster than previously estimated in the literature. We also analyze how both financial constraints and market timing variables affect adjustments toward a leverage target.     

CEO EXTRAVERSION AND CAPITAL STRUCTURE DECISIONS: THE ROLE OF FIRM DYNAMICS,PRODUCT MARKET COMPETITION,AND FINANCIAL CRISIS

Using panel data of U.S. firms, we focus on an important yet understudied facet of the chief executive officer's (CEO) personality—extraversion—and how it affects corporate capital structure decisions. We examine how this relation is moderated by financing (tax) benefits, financial crisis, firm size, growth opportunities, and collateralization. The results show that firms managed by extraverted CEOs use greater financial leverage, adjusting toward target leverage levels at a faster speed, with about half-life within a year for book and market leverage. In addition, the positive extraversion–leverage relation is enhanced for firms that are large, have greater collateralizable assets, and are more vulnerable to external shocks (financial crisis). Last, although the positive extraversion–leverage relation holds particularly when product market competition is high, the effect is attenuated for high-growth opportunity firms.
