Market Efficient Portfolios in a Systemic Economy

Diversification vs. Diversity – How is the Efficiency of Markets Affected? Prices aggregate information that is dispersed in the economy; they thereby facilitate the allocation of scarce resources. Inefficiencies may arise from deviations of market prices from their fundamental values. In “Market Efficient Portfolios in a Systemic Economy”, Awiszus, Capponi, and Weber investigate the impact of the trade-off between diversity and diversification on inefficiencies in secondary markets due to asset illiquidity and leverage constraints of financial institutions. The authors identify two key determining factors. These are the systemic significance of the banks and the statistical properties of the fundamental asset shocks. Systemic significance is driven by the banks’ target leverage, their trading strategies, and the illiquidity characteristics of the assets. The paper demonstrates that portfolio diversification is typically not efficient. In fact, efficient portfolio holdings may strongly deviate from this standard paradigm, especially if the banks have similar characteristics.

Three Essays on Capital Structure

<p>This thesis consists of three self-contained essays about the relationship between cash flow and investment volatility and firm capital structure and cash holdings. Capital structure measures sources of financing that allow a firm to operate, invest, and grow. The first essay reviews the theoretical relationship between firm capital structure and cash flow volatility, develops testable hypotheses, constructs a data set, and then tests the hypotheses using several measures of firm cash flow volatility and econometric methods that account for the non-linear relationship of proportional variables. Overall, the evidence indicates that ceteris paribus, a one standard deviation increase from the mean of cash flow volatility, implies approximately by 24% decrease in the long-term debt ratio, a 26% decrease in probability of holding debt with over 10 years to maturity, and a 39% increase in the probability of not holding either short or long term debt. These findings are novel in the empirical capital structure literature and show the importance of cash flow volatility in firm financial policies. The second essay studies the financing behaviour of Hospital Corporation of America (HCA) from 1990 to 2013 and demonstrates variation in HCA’s market and book leverage ratios due to 1) mergers and acquisitions and divestitures that change the firm’s total assets, 2) share buybacks, and 3) leveraged buyouts and public offerings that change the firm’s ownership. The paper scrutinizes variation in HCA’s market and book leverage ratios independently as well as relative to each other. Our evidence shows that i) HCA’s management team used HCA’s excess cash from divestitures to repurchase HCA’s stock rather than pay off HCA’s debt, ii) HCA’s market leverage ratio tends to stay in a target leverage zone, and iii) in some years HCA’s management team used the book leverage ratio as a tool to keep the market leverage ratio inside a target leverage zone. In the third essay, we investigate the influence of investment volatility on capital structure and cash holdings using a broad definition of investment. Despite theoretical motivation, the relationship between investment volatility and capital structure has not been studied in the empirical literature. All in all, our evidence suggests that i) firms with relatively high capital expenditure and acquisition investment volatility hold relatively higher levels of debt and lower levels of cash, ii) firms fund large capital expenditures and/or acquisition by increasing debt or decreasing cash, and iii) immediately after funding large investment firms reduce debt levels and increase cash holdings. Research and development investment volatility is related to lower debt levels and higher cash levels, and does not exhibit similar investment spike funding. Overall, our results are consistent with parts, but not all, of the DeAngelo, DeAngelo and Whited (2011) model.</p>

Financial Leverage and Debt Maturity Targeting: International Evidence

We provide evidence on leverage and debt maturity targeting in a large international setting. There are key differences in the relative importance of institutional factors in explaining actual as opposed to target capital structures. Targets and target deviations are plausibly influenced by the institutional environment. Firms from countries with strong legal institutions target lower leverage and higher long-term debt, whereas better-functioning financial systems result in lower target leverage and long-term debt. Financial crisis has shifted the desired structure of the securities toward shorter maturities and has led to more prevalent target deviations. Better institutions significantly decrease the likelihood of target deviations.

Does asymmetric information affect firm's financing decisions?

PurposeThe authors examine the impact of asymmetric information on firm's financing decisions, the feedback effect of changes in capital structure on the level of asymmetric information, and the speed of adjustments in capital structure on its target leverage.Design/methodology/approachThe authors extract the data on 280 non-financial firms listed in the Pakistan Stock Exchange (PSX) from the DataStream. The authors implement the generalized method of moments (GMM), complemented by the fixed effect model (FEM) to estimate the model coefficients.FindingsThe authors find that asymmetric information significantly affects the financing decisions; and that on average, firms adjust 26% of the total debt toward their target capital structure. The negative effect from the difference between the observed and target changes in leverage on asymmetric information confirms that capital structure changes act as a signal for future profitability and helps the management to lower its level of asymmetric information.Originality/valueThe findings offer fresh insight into the effect of asymmetric information on financing decisions, as well as the speed of adjustment of capital structure toward its target leverage, in the context of the firms working in emerging markets like Pakistan. To the authors’ best knowledge, this is the first study to investigate the impact of asymmetric information on financing decisions that incorporate firm's age, size and the global financial crises 2007–2008. The authors construct an asymmetric information index using both accounting and finance measures of asymmetry.

Do Capital Structure Models Square with the Dynamics of Payout?

We explore whether theoretically the target leverage and pecking-order models can be reconciled with payout smoothing. Investment absorbs a significant part of income and asset volatility if the firm follows both a payout target and a net debt ratio (NDR) target. A positive (negative) NDR amplifies (dampens) shocks in assets. Slow adjustment toward the NDR target facilitates payout smoothing. Under strict pecking-order financing, income shocks are absorbed primarily by changes in net debt. More payout smoothing implies a stronger negative relation between debt and net income. Shocks to assets in place need not affect current payout. Expected final online publication date for the Annual Review of Financial Economics, Volume 13 is November 2021.

Speed of Adjustment towards Target Leverage in the ASEAN Countries

This study aims to investigate the speed of adjustment towards target total debt, long-term debt and short-term debt of the Association of South East Asian Nations (ASEAN) namely Malaysia, Singapore, Indonesia and Thailand. The sample of this study included 400 publicly listed firms from 2007 to 2017. Analyses were done with two-step System Generalised Method of Moments (SYS-GMM). Using large sample, the results showed that ASEAN firms are under-adjusted and adjusting with the speed of 30.95%, 37.49% and 40.11% toward total debt, long-term debt and short-term debt, accordingly. To close half of the leverage gap, ASEAN firms need 1.87, 1.62 and 1.35 years for total debt, long-term debt and short-term debt, respectively. The results based on individual country indicated that each country has its own adjustment speed to achieve the target leverage. This study suggests that ASEAN firms are attempting to alter the leverage to its optimum.

Trade Credit and Capital Structure Adjustment Speed: Evidence From Chinese Listed Firms

This paper examines the impact of trade credit on the speed of capital structure adjustment toward target leverage using an integrated dynamic partial adjustment model. Trade credit is an important substitute for debt financing and gives firms a low-cost means of adjusting leverage toward the target capital structure in China. We measure trade credit by accounts payable. Using the public listed company data from 1998 to 2016, we find that trade credit accelerates capital structure adjustment. The asymmetric impacts on the capital structure adjustment speed in different situations are also evidenced. The positive impact of trade credit on the speed of capital structure adjustment is more pronounced for over-levered firms. The trade credit also accelerates the speed of capital structure adjustment more quickly for high market share firms. Our results imply that firms use trade credit to save cash flow and restore the leverage level to the target capital structure in China.
