Foreign bias in institutional portfolio allocation: The role of social trust

Wolfgang Drobetz, Marwin Mönkemeyer, Ignacio Requejo, Henning Schröder
Journal of Economic Behavior & Organization | 10/2023
We study the role of social trust in the equity allocation decisions of global investors using a large sample of institutionally managed portfolios of 8,088 investors from 33 countries over the 2000 through 2017 period. The negative relationship between social trust and foreign bias suggests that institutional investors from high-social trust countries are less prone to underinvesting in foreign equity. Our results provide credence to an information-based explanation, indicating that social trust reduces foreign bias by compensating for the lack of information about foreign stock markets. Moreover, the effect of social trust on foreign bias is stronger if host-country institutions are weak, while it vanishes when the host country is characterized by strong institutions. The informal institution of social trust compensates for the lack of well-functioning formal country-level institutions in international portfolio decisions. Finally, the allocation effect resulting from social trust is different from “blind” trust. The portfolios of high-trust investors exhibit higher cross-country diversification and an enhanced portfolio risk-return trade-off.

Institutional blockholder networks and corporate acquisition performance

Gishan Dissanaike, Wolfgang Drobetz, Marwin Mönkemeyer, Henning Schröder
Academy of Management Proceedings | 07/2023
We examine 17,207 U.S. mergers and acquisitions by public firms over the 1980–2019 period and find that the acquirer abnormal announcement returns are higher for firms held by more central investors in the network of active institutional blockholdings. This finding is robust to firm and deal characteristics, and it also extends to alternative network and return measures. To provide evidence on causality, we exploit extreme industry returns that lead to plausibly exogenous variation in investors’ monitoring ability. The positive effect of blockholder centrality on acquirer abnormal announcement returns only exists in information-sensitive (i.e., private) deals and only among institutions that have a comparative advantage in exploiting monitoring information. Our findings suggests that institutional investors obtain an information advantage through the network, which increases their monitoring ability.

Institutional investors and corporate environmental costs: The roles of investment horizon and investor origin

European Financial Management | 06/2023 | Forthcoming
Using a large international dataset that quantifies corporate environmental costs, we analyze the influence of institutional investor ownership, particularly investment horizon and investor origin, on the monetized environmental impact generated by their investee firms. Institutional investor ownership is negatively related to corporate environmental costs. This effect is driven by long-term foreign institutional investors, especially investors from advanced economies. Foreign institutional investors transfer higher norms and standards from their home countries to their investee firms abroad. Corporate environmental costs are negatively correlated with firm valuation and positively correlated with the firm’s cost of equity. To the extent that corporate environmental costs are not already reflected in conventional ESG ratings, our results shed new light on the role of institutional investors in shaping corporate environmental impact.

Team networks and venture success: Evidence from token-financed startups

Wolfgang Drobetz, Kathrin Rennertseder, Henning Schröder
HFRC Working Paper Series | Version 05/2023
Evidence shows that social network structures drive important economic outcomes. Building on social network theory, this study is the first to analyse the impact of team networks on venture success. Using information about team affiliations for a sample of token-financed startups, we model networks based on team interlocks across firms. Ventures with well-connected teams exhibit higher market valuations and higher token market liquidity. These effects seem to be driven by network-induced information and communication advantages. Specifically, we show that networks matter most when publicly available information is limited. The findings remain robust after controlling for non-team networks and endogeneity.

The hurdle-rate effect on patents: Equity risk premium and corporate innovation by public firms in the U.S., 1977-2018

David B. Audretsch, Wolfgang Drobetz, Eva Elena Ernst, Paul P. Momtaz, Silvio Vismara
HFRC Working Paper Series | Version 05/2023
Schumpeterian arguments of “creative destruction” predict that innovation is countercyclical. However, empirical findings demonstrate the contrary. We apply corporate finance principles to innovation economics and propose a “hurdle-rate theory of inventive procyclicality.” Macroeconomic episodes of high equity risk premia (ERP) stifle innovation because many R&D projects do not pass corporate budgeting decisions when discount rates are high. Consistent evidence suggests that the hurdle-rate effect is less pronounced in firms with financial slack, institutional ownership with long-term orientation, and weak product-market competition. In an attempt to reconcile the procyclical evidence with Schumpeter’s countercyclical theory, we show that firms engaging in exploratory search suffer less during high-ERP episodes than those focusing on exploitative search, and patents developed during high-ERP periods have a higher technological impact and receive significantly more forward citations. Finally, we exploit the staggered variation in state-level R&D tax credits in difference-in-differences analyses to establish a causal link between the ERP and patent value.

The financial and non-financial performance of token-based crowdfunding: Certification arbitrage, investor choice, and the optimal timing of ICOs

Niclas Dombrowski, Wolfgang Drobetz, Lars Hornuf, Paul P. Momtaz
HFRC Working Paper Series | Version 04/2023
What role does the selection of an investor and the timing of financing play in initial coin offerings (ICOs)? We investigate the operating and financial performance of ventures conducting ICOs with different types of investors at different points in the ventures’ life cycle. We find that, relative to purely crowdfunded ICO ventures, institutional investor-backed ICO ventures exhibit poorer operating performance and fail earlier. However, conditional on their survival, these ventures financially outperform those that do not receive institutional investor support. The diverging effects of investor backing on financial and operating performance are consistent with our theory of certification arbitrage; i.e., institutional investors use their reputation to drive up valuations and quickly exit the venture post-ICO. Our findings further indicate that there is an inverted U-shaped relationship for fundraising success of ICO ventures over their life cycle. Another inverted Ushaped relationship exists for the short-term financial performance of ICO ventures over their life cycle. Both the fundraising success and the financial performance of an ICO venture initially increase over the life cycle and eventually decrease after the product piloting stage.

Performance measurement of crypto funds

Niclas Dombrowski, Wolfgang Drobetz, Paul P. Momtaz
Economics Letters | 04/2023 | Forthcoming
Crypto funds (CFs) are a growing intermediary in cryptocurrency markets. We evaluate CF performance using metrics based on alphas, value at risk, lower partial moments, and maximum drawdown. The performance of actively managed CFs is heterogenous: While the average fund in our sample does not outperform the overall cryptocurrency market, there seem to be some few funds with superior skills. Given the non-normal nature of fund returns, the choice of the performance measure affects the rank orders of funds. Compared to the Sharpe ratio, the most commonly applied metric in practice, performance measures based on alphas and maximum drawdown lead to diverging fund rankings. Depending on their ranking of preferences, CF investors should thus consider a bundle of metrics for fund selection and performance measurement.

Decentralized finance, crypto funds, and value creation in tokenized firms

Douglas Cumming, Niclas Dombrowski, Wolfgang Drobetz, Paul P. Momtaz
HFRC Working Paper Series | Version 05/2022
Crypto Funds (CFs) represent a novel investor type in entrepreneurial finance. CFs intermediate Decentralized Finance (DeFi) markets by pooling contributions from crowd-investors and investing in tokenized startups, combining sophisticated venture- and hedge-style investment strategies. We compile a unique dataset combining token-based crowdfunding (or Initial Coin Offerings, ICOs) data with proprietary performance data of CFs. CF-backed startup ventures obtain higher ICO valuations, outperform their peers in the long run, and benefit from token price appreciation around CF investment disclosure in the secondary market. Moreover, CFs beat the market by roughly 2.5% per month. Their outperformance is persistent, suggesting that CFs deliver abnormal returns because of skill, rather than luck. These performance effects for CFs and CF-backed startups are driven by a fund’s investor network centrality. Overall, our study paves the way for research on what some refer to as the “crypto fund revolution” in entrepreneurial finance.

Institutional investment horizons, corporate governance, and credit ratings: International evidence

Hamdi Driss, Wolfgang Drobetz, Sadok El Ghoul, Omrane Guedhami
HFRC Working Paper Series | Version 01/2021
Using a comprehensive set of firms from 57 countries over the 2000–2016 period, we examine the relation between institutional investor horizons and firm-level credit ratings. Controlling for firm- and country-specific factors, as well as for firm fixed effects, we find that larger long-term (short-term) institutional ownership is associated with higher (lower) credit ratings. This finding is robust to sample composition, alternative estimation methods, and endogeneity concerns. Long-term institutional ownership affects ratings more during times of higher expropriation risk, for firms with weaker internal governance, and for those in countries with lower-quality institutional environments. Additional analysis shows that long-term investors can facilitate access to debt markets for firms facing severe agency problems. These findings suggest that, unlike their short-term counterparts, long-term investors can improve a firm’s credit risk profile through effective monitoring.

Institutional ownership and firm performance in the global shipping industry

Wolfgang Drobetz, Sebastian Ehlert, Henning Schröder
Transportation Research Part E: Logistics and Transportation Review | 01/2021 | Forthcoming
We examine the effect of institutional investors on the valuation of listed shipping firms. Institutional investors have a positive influence on the market value of shipping firms, confirming that institutional ownership is a “universal” corporate governance mechanism. This valuation effect is more pronounced in firms dominated by institutional investors with a short-term investment horizon. It is also stronger in firms with high stock liquidity, suggesting that short-term investors, through the threat of exit, are able to mitigate agency conflicts and improve corporate governance. Investment regressions indicate that shipping firms with a larger fraction of short-term investors are better able to exploit growth opportunities.

The economics of law enforcement: Quasi-experimental evidence from corporate takeover law

Gishan Dissanaike, Wolfgang Drobetz, Paul P. Momtaz, Jörg Rocholl
Journal of Corporate Finance | 12/2020 | Forthcoming
This paper examines the impact of takeover law enforcement on corporate acquisitions. We use the European Takeover Directive as a natural experiment, which harmonizes takeover law across countries, while leaving its enforcement to the discretion of individual countries. We exploit this heterogeneity in enforcement quality across countries in a difference-in-differences-in-differences model, while employing an overall inductive research approach, following Karpoff and Whittry’s (2018) recommendation. We find that acquirer returns increase in countries with improvements in takeover law, driven by better target selection and lower cost of financing. The increase in acquirer returns is lower in weak enforcement jurisdictions, which we identify by developing a novel Takeover Law Enforcement Index (TLEI). The findings show that takeover law can mitigate agency conflicts, but its true value depends on its enforcement. Our results are strongly robust to alternative model specifications.

Policy uncertainty, investment, and the cost of capital

Wolfgang Drobetz, Sadok El Ghoul, Omrane Guedhami, Malte Janzen
Journal of Financial Stability | 11/2020
We examine the effect of economic policy uncertainty on the relation between investment and the cost of capital. Using the news-based index developed by Baker et al. (2016) for twenty-one countries, we find that the strength of the negative relation between investment and the cost of capital decreases during times of high economic policy uncertainty. An increase in policy uncertainty reduces the sensitivity of investment to the cost of capital most for firms operating in industries that depend strongly on government subsidies and government consumption as well as in countries with high state ownership. Consistent with the price informativeness channel, we find that an increase in policy uncertainty reduces the investment-cost of capital sensitivity for firms from more opaque countries, firms with low analyst coverage, firms with no credit rating, and small firms. We conclude that economic policy uncertainty distorts the fundamental relation between investment and the cost of capital.

Institutional investment horizons and firm valuation around the world

Wolfgang Drobetz, Simon Döring, Sadok El Ghoul, Omrane Guedhami, Henning Schröder
Journal of International Business Studies | 09/2020 | Forthcoming
Using a comprehensive dataset of firms from 34 countries, we study the effect of institutional investors’ investment horizons on firm valuation around the world. We find a positive relation between institutional ownership and firm value that is driven by short-horizon institutional investors. Accounting for the interaction between investors’ investment horizon and nationality, we show that foreign short-horizon institutions, which are more likely to discipline managers through the threat of exit rather than engaging in monitoring made costly by the liability of foreignness, are the investor group with the strongest effect on firm value. Reinforcing the threat of exit channel, we find that the value-enhancing effect of short-horizon investors is stronger in the presence of multiple short-horizon investors, who are more likely to engage in competitive trading. The positive valuation effect of short-horizon investors is stronger when stock liquidity is high, which makes the exit threat more credible, and in firms prone to free cash flow agency problems. Overall, our results are consistent with short-horizon institutional investors, especially foreign institutional owners, affecting firm value by disciplining managers through a credible threat of exit.

Cross-country determinants of institutional investors’ investment horizons

Wolfgang Drobetz, Simon Döring, Sadok El Ghoul, Omrane Guedhami, Henning Schröder
Finance Research Letters | 06/2020 | Forthcoming
Using a large dataset of firms from 35 countries, we study the country-level determinants of institutional investors’ investment horizons. We show that an equity investor-friendly institutional environment is more important for long-term investors, while short-term investors seem to be less concerned about the quality of the financial and legal environment. Beyond the financial and legal structure, the cultural environment and economic policy uncertainty in a country are other important determinants of investor horizons. These findings improve our understanding of cross-country differences in the corporate governance role, i.e., engagement vs. exit, of institutional investors.

Antitakeover provisions and firm value: New evidence from the M&A market

Wolfgang Drobetz, Paul P. Momtaz
Journal of Corporate Finance | 06/2020
New evidence from acquisition decisions suggests that antitakeover provisions (ATPs) may increase firm value when internal corporate governance is sufficiently strong. We document that, in Germany, firms with stronger ATPs, and particularly supermajority provisions, are better acquirers. Managers of high-ATP firms create value in acquisitions by making governance-improving deals. They are more likely to engage in acquisitions that reduce their own entrenchment level and less likely to invest in declining industries. The empirical evidence is consistent with a short-termist interpretation. Takeover threats can induce myopic investment decisions, which ATPs can mitigate. They lead managers to engage more often in value-creating long-term and innovative investing, and increase a firm's sensitivity to investment opportunities. Our findings contribute to a growing literature challenging conventional wisdom that the agency-increasing effect of ATPs empirically dominates the myopia-eliminating effect, suggesting that a more contextual view of the value implications of ATPs is necessary.

Competition policy and the profitability of corporate acquisitions

Gishan Dissanaike, Wolfgang Drobetz, Paul P. Momtaz
Journal of Corporate Finance | 06/2020
Merger control exists to help safeguard effective competition. However, findings from a natural experiment suggest that regulatory merger control reduces the profitability of corporate acquisitions. Uncertainty about merger control decisions reduces takeover threats from foreign and very large acquirers, therefore facilitating agency-motivated deals. Valuation effects are more pronounced in countries with stronger law enforcement and in more concentrated industries. Our results suggest that competition policy may impede the efficiency of the M&A market.

Corporate insider trading and return skewness

Wolfgang Drobetz, Emil Mussbach, Christian Westheide
Journal of Corporate Finance | 02/2020
Corporate insider trades predict idiosyncratic return skewness. CEO purchases are followed by an increase and CEO sales by a decrease in idiosyncratic skewness. The evidence suggests that this effect is driven by personal preferences rather than behavioral biases such as overconfidence. Our findings are consistent with the interpretation that CEOs, who are generally considered to be underdiversified, optimize their holdings by taking their preference for positive return skewness into account. We observe particularly robust results for CEO sales, which substantiates the less common notion that insider sales can be informative for investors.

Corporate governance convergence in the European M&A market

Wolfgang Drobetz, Paul P. Momtaz
Finance Research Letters | 01/2020
Cross-border acquisitions lead to improvements in shareholder rights and more dispersed ownership structures in a large sample of intra-European takeovers. These findings are evidence of corporate governance convergence toward the Anglo-Saxon system through cross-border takeovers. However, we find no support for the corporate governance motive hypothesis in cross-border acquisitions even after accounting for potential sample selectivity. Although acquirers have significantly better shareholder rights than their targets, there are no robust marginal bidder wealth effects for firms that acquire either weaker or stronger governance foreign targets. Instead, bidder wealth effects in cross-border acquisitions are better explained by acculturation costs.

Token offerings: A revolution in corporate finance?

Paul P. Momtaz, Kathrin Rennertseder, Henning Schröder
HFRC Working Paper Series | Version 03/2019
Token offerings or initial coin offerings (ICOs) are smart contracts based on blockchain technology designed to raise external finance without an intermediary. The new technology might herald a revolution in entrepreneurial and corporate finance, with soaring market growth rates over the last two years. This paper surveys the market evolution, offering mechanisms, and token types. Stylized facts on the pricing and long-term performance of ICOs are presented, and practical implications for this young market to thrive are discussed.

Capital allocation and ownership concentration in the shipping industry

Wolfgang Drobetz, Malte Janzen, Ignacio Requejo
Transportation Research Part E: Logistics and Transportation Review | 02/2019
We measure the sensitivity of investment to changes in investment opportunities in the shipping industry, and test whether this relation is moderated by ownership concentration. For a sample of 126 globally listed shipping firms, we find that investment in commercial shipping follows freight rates, a measure of the potential income stream from owning a vessel. Ownership concentration, measured as the ownership stake of the largest shareholder, reinforces the positive effect of freight rates on investment, indicating a higher relative efficiency of capital allocation. The positive impact ownership has on the investment-freight rate sensitivity also translates into higher firm value. An analysis of investor identity shows that our results are driven by the group of firms where the largest owner is a financial investor, who is usually more focused on shareholder value maximization.

Investment and financing decisions of private and public firms

Wolfgang Drobetz, Malte Janzen, Iwan Meier
Journal of Business Finance and Accounting | 12/2018
We examine differences in the allocation of cash flow between Western European private and public firms. Public firms have a higher investment‐cash flow sensitivity than comparable private firms. This difference is not attributable to more severe financing constraints of public firms. Instead, because differences in investment‐cash flow sensitivities are only observed for the unexpected portion of firms’ cash flow, the empirical evidence supports an agency‐based explanation. Similar patterns are observable for the expected and unexpected portion of firms’ shareholder distributions. Our results are driven by firms from countries with low ownership concentration and more liquid stock markets, where shareholders have lower incentives to monitor. The results are also more pronounced for public firms with low industry Tobin's q and high free cash flow, which are more prone to suffer from agency problems.

Cyclicality of growth opportunities and the value of cash holdings

Meike Ahrends, Wolfgang Drobetz, Tatjana Xenia Puhan
Journal of Financial Stability | 08/2018
We show that business cycle dynamics and, in particular, the cyclicality of a firm’s growth opportunities, determine the value of corporate cash holdings. An additional dollar of cash is more valuable for firms with less procyclical expansion opportunities. This valuation effect is strongest for low leverage and high R&D firms, but is independent of their financial status. Corporate cash holdings provide the flexibility to invest for firms that have expansion opportunities during crisis times with business cycle downturns and supply-side financial constraints. Cash holdings in firms with less procyclical growth opportunities are associated with higher investment and better operating performance.

Industry expert directors

Wolfgang Drobetz, David Oesch, Markus Schmid, Felix von Meyerinck
Journal of Banking and Finance | 07/2018
We analyze the valuation effect of board industry experience and channels through which industry experience of outside directors relates to firm value. Our analysis shows that firms with more experienced outside directors are valued at a premium compared to firms with less experienced outside directors. Additional analyses, including a quasi-experimental setting based on director deaths, mitigate endogeneity concerns. The association between having directors with more industry experience and higher firm value is more pronounced for firms with larger investment programs, larger cash reserves, and during crises. In contrast, it is weaker in more dynamic industries, i.e., industries that rank high in terms of sales growth, R&D expenditures, merger activities, competitive threat, and product market changes, where the value of previously acquired experience is likely to be diminished. Overall, our findings are consistent with board industry experience being a valuable corporate governance mechanism.

Global cash flow sensitivities

Wolfgang Drobetz, Simon Döring, Malte Janzen, Iwan Meier
Finance Research Letters | 06/2018
We examine the role of a country's institutional framework for investment and financing activities. A country's financial structure, investor rights, and legal environment are important determinants of the relation between cash flow and firms’ investment and financing behavior. Firms from countries with a stronger institutional framework exhibit higher financing-cash flow sensitivities. These firms are more likely to substitute a cash flow shortfall with issuing equity. Conversely, investment-cash flow sensitivities are higher for firms in countries with a weaker institutional framework.

Corporate cash holdings in the shipping industry

Meike Ahrends, Wolfgang Drobetz, Nikos K. Nomikos
Transportation Research Part E: Logistics and Transportation Review | 04/2018
We examine the corporate cash holdings of listed shipping companies. Shipping firms hold more cash than similar firms in other asset-heavy industries. Higher cash holdings in the shipping industry are not attributable to firm- or country-level characteristics, but rather to the higher marginal value of cash. Shipping firms value an additional dollar of cash higher than matched manufacturing firms, regardless of their financial constraints status, but depending on their cultural background and the cyclicality of their expansion opportunities. Less procyclical shipping firms have a higher marginal value of cash, and this valuation effect is most pronounced in bad times of the business cycle when external capital supply tends to become scarce. Overall, it appears that shipping companies are more conservative than their peers in managing their cash positions.

Determinants of management earnings forecasts: The case of global shipping IPOs

Wolfgang Drobetz, Dimitrios Gounopoulos, Anna Merika, Andreas Merikas
European Financial Management | 11/2017
Firms that go public on global stock markets are not obliged to disclose earnings forecasts in their prospectuses. We use this fact to examine the shipping industry, where most firms voluntarily issue earnings forecasts during the IPO process, thus providing unique, international‐level evidence. We find overall pessimistic forecasts of ship owners, primarily because of the industry's uncertain and volatile environment. High ship owner participation after going public is associated with less accurate earnings forecasts. Our results further indicate that financial leverage, a listing in an emerging stock market, and global market conditions are other main factors responsible for inaccurate earnings forecasts.

Cash flow sensitivities during normal and crisis times: Evidence from shipping

Wolfgang Drobetz, Rebekka Haller, Iwan Meier
Transportation Research Part A: Policy and Practice | 08/2016
Using a system of equations model, we analyze how cash flow shocks influence the investment and financing decisions of shipping firms in different economic environments. Even financially healthy shipping firms felt strong negative effects on their financing activities during the recent crisis. These firms were nevertheless able to increase long-term debt. Banks internalized the impact of foreclosure decisions on vessel prices and avoided an industry-wide collateral channel effect. Even during benign economic conditions, financially weak shipping firms underinvest because of their inability to raise sufficient external capital. The substitution between long- and short-term debt during the pre-2008 crisis periods shows that the composition of financing sources is more indicative of whether firms face financial constraints than the pure size of the financing-cash flow sensitivities. An analysis of firms’ excess cash holdings confirms the importance of financial flexibility.

Systematic risk behavior in cyclical industries: The case of shipping

Wolfgang Drobetz, Christina Menzel, Henning Schröder
Transportation Research Part E: Logistics and Transportation Review | 04/2016
This study explores macroeconomic and industry-level effects on corporate systematic risk (or beta) for the international shipping industry. We document the extent to which stock market betas fluctuate over time in this asset-intensive and cyclical industry. Moreover, we analyze the fundamental determinants of systematic risk. We find evidence for high levels of systematic risk in shipping stocks, which match the fundamental risk characteristics of the industry (such as high financial and operating leverage). Shipping firms exhibit distinct industry-specific beta dynamics compared to firms from benchmark sectors or the average firm in the S&P 500 index. Changes in both economic conditions and industry-specific risk factors explain large proportions of beta variation in the cross-section of firms and over time.

Corporate finance in Germany: Structural adjustments and current developments

Wolfgang Bessler, Wolfgang Drobetz
Journal of Applied Corporate Finance | 01/2016
For a very long time, the financing of German companies was dominated by German universal banks, which functioned as sources of both capital-as equity holders as well as providers of loans-and corporate governance. Although internal finance (retained earnings) has always been and will remain the most important source of finance, several recent developments have forced German companies to search for alternatives to their traditionally heavy dependence on bank lending. As a result, the composition of external finance has changed, with substantial net contributions of corporate bond and equity offerings. Furthermore, both the equity ratios and cash holdings of German companies have increased over the years. Thus, although the German financial system still exhibits many differences from those in the U.S. and U.K., the financing patterns of German companies have to some extent converged with those of their peers from Anglo-American market-based financial systems. The growth in recent years of German capital markets-and of German companies' reliance on them-has led to important changes in both German and European corporate governance, including the evolution of a common European market for corporate control that is still in its early stages.

Equity issues and stock repurchases of initial public offerings

Wolfgang Bessler, Wolfgang Drobetz, Martin Seim, Jan Zimmermann
European Financial Management | 01/2016
We investigate the financing strategies and valuation effects of 247 IPO firms at the ‘Neuer Markt’ in Germany that either issued additional equity (SEO) or repurchased shares (SRP) within five years after going public. IPOs issuing additional equity exhibit a temporary outperformance before the event, but negative announcement returns and a long‐run underperformance. In contrast, repurchasing IPOs experience positive announcement returns and no long‐run underperformance. Free cash flow problem resulting from mandatory equity issuance at the IPO explain the SRP decision. Our findings for SEOs are consistent with a staged financing strategy, while we find no evidence for market timing.

Heterogeneity in the speed of capital structure adjustment across countries and over the business cycle

Wolfgang Drobetz, Dirk C. Schilling, Henning Schröder
European Financial Management | 11/2015
This study analyses the heterogeneity in the speed of capital structure adjustment. Using a doubly‐censored Tobit estimator that accounts for mechanical mean reversion in leverage ratios, the speed of adjustment is 25% per year in a large international sample, supporting the economic relevance of the trade‐off theory. Differences in the adjustment speed across financial systems are attributable to differences in the costs of adjustment. Macroeconomic and micro‐level supply‐side constraints also affect the dynamics of leverage. Firms adjust more slowly during recessions, and the business cycle effect on adjustment speed is most pronounced for financially constrained firms in market‐based countries.

The returns to hedge fund activism in Germany

Wolfgang Bessler, Wolfgang Drobetz, Julian Holler
European Financial Management | 01/2015
Recent regulatory changes in the German financial system shifted corporate control activities from universal banks to other capital market participants. Particularly hedge funds took advantage of the resulting control vacuum by acquiring stakes in weakly governed and less profitable firms. We document that, on average, hedge funds increased shareholder value in the short‐ and long‐run. However, more aggressive hedge funds generated only initially higher returns and their outperformance quickly reversed, whereas non‐aggressive hedge funds ultimately outperformed their aggressive peers. These findings suggest that aggressive hedge funds attempt to expropriate the target firm's shareholders by exiting at temporarily increased share prices.

Share repurchases of initial public offerings: Motives, valuation effects, and the impact of market regulation

Wolfgang Bessler, Wolfgang Drobetz, Martin Seim
European Journal of Finance | 01/2014
This study investigates the motives and valuation effects of share repurchase announcements of German firms during the 1998–2008 period, addressing the question why initial public offering (IPO) firms repurchase shares soon after going public. While our focus is on IPO firms, we also examine the impact of firm size by differentiating between IPO and established DAX/MDAX firms and by analyzing the source of surplus cash holdings, that is, either from equity issuances or from operating cash flows. We further explore the impact of the regulatory environment. Our empirical analysis reveals significant differences between the IPO and DAX/MDAX subsamples regarding their repurchase motives, stock price performance, and explanatory factors. Standard corporate payout theories are essential in explaining the different valuation effects. Our empirical analysis suggests agency costs of free cash flow as the main reason for the observed valuation effects of both IPO and DAX/MDAX firms, yet for different reasons. While DAX/MDAX firms continuously generate high operating cash flows before and after repurchasing shares, IPO firms exhibit low operating cash flows during the entire period but large surplus cash holdings due to the mandatory equity issuance at their public offering. Overall, the repurchase decisions of IPO firms are best explained by the agency costs of cash holdings and the unique rules and regulations of the German stock exchange.

The international zero-leverage phenomenon

Wolfgang Bessler, Wolfgang Drobetz, Rebekka Haller, Iwan Meier
Journal of Corporate Finance | 12/2013
We analyze the zero-leverage phenomenon around the world. Countries with a common law system, high creditor protection, and a dividend imputation or dividend relief tax system exhibit the highest percentage of zero-leverage firms. The increasing prevalence of zero-leverage firms in all sample countries is related to market-wide forces during our sample period, such as IPO waves, shifts in industry composition, increasing asset volatility, and decreasing corporate tax rates. Firm-level comparisons reveal that only a small number of firms deliberately maintain zero-leverage. Most zero-leverage firms are constrained by their debt capacity. Analyzing the time-series dynamics of leverage and investment behavior, we further show that firms which pursue a zero-leverage policy only for a short period of time seek financial flexibility.

Capital structure decisions of globally-listed shipping companies

Wolfgang Drobetz, Dimitrios Gounopoulos, Andreas Merikas, Henning Schröder
Transportation Research Part E: Logistics and Transportation Review | 06/2013
Debt capital has traditionally been the most important source of external finance in the shipping industry. The access that shipping companies nowadays have to the capital markets provides them with a broader range of financing instruments. As such, this study investigates the determinants of capital structure decisions using a sample of 115 exchange-listed shipping companies. We test whether listed shipping companies follow a target capital structure, and we analyze their adjustment dynamics after deviations from this target leverage ratio. When compared with industrial firms from the G7 countries, shipping companies exhibit higher leverage ratios and higher financial risk. Standard capital structure variables exert a significant impact on the cross-sectional variation of leverage ratios in the shipping industry. Asset tangibility is positively related to corporate leverage, and its economic impact is more pronounced than in other industries. Profitability, asset risk, and operating leverage are all inversely related to leverage. There is only weak evidence for market-timing behavior of shipping companies. Because demand and supply in the maritime industry are closely related to the macroeconomic environment, leverage behaves counter-cyclically. Using different dynamic panel estimators, we further document that the speed of adjustment after deviations from the target leverage ratio is lower during economic recessions. On average, however, the capital structure adjustment speed in the maritime industry is higher compared with the G7 benchmark sample. These findings indicate that there are substantial costs of deviation from the target leverage ratio due to high expected costs of financial distress. Our results have implications for shipping companies’ risk management activities.

Financing shipping companies and shipping operations: A risk‐management perspective

Stefan Albertijn, Wolfgang Bessler, Wolfgang Drobetz
Journal of Applied Corporate Finance | 12/2011
Shipping has always been a volatile and cyclical business. The extreme changes in revenues, operating cash flows, and asset values during the recent financial crises have upset the usual means of financing shipping companies. While bank debt will remain important in the future, the new regulatory environment has been forcing shipping banks to shift these risks from their balance sheets to capital markets through instruments such as loan securitization. As a result, the shipping industry will increasingly look to capital markets for external funds. And shipping banks are likely to change from being commercial bank lending institutions to becoming more like investment banks that arrange a variety of financing solutions, including high yield bonds or public equity. Risk management will be central to shipping companies in this new environment. Shipping companies can manage their own risks by modifying operations, employing freight and vessel price derivatives, or adjusting their capital structures. To arrive at the value‐maximizing combination of these three basic methods, they must decide which risks to bear, which to manage internally, and which to transfer to the capital markets. These decisions require shipping financial managers to assess the effect of each risk on firm value, understand how each contributes to total risk, and determine the most cost‐effective way to limit that risk to an acceptable level.

Information asymmetry and financing decisions

Wolfgang Bessler, Wolfgang Drobetz, Matthias C. Grüninger
International Review of Finance | 03/2011
This study conducts tests of the pecking order theory using an international sample with more than 6000 firms over the period from 1995 to 2005. The high correlation between net equity issuances and the financing deficit discredits the static pecking order theory. Rather than analyzing the predictions of the theory, we test its core assumption that information asymmetry is an important determinant of capital structure decisions. Our empirical results support the dynamic pecking order theory and its two testable implications. First, the probability of issuing equity increases with less pronounced firm‐level information asymmetry. Second, firms exploit windows of opportunity by making relatively larger equity issuances and build up cash reserves (slack) after declines in firm‐level information asymmetry. Firms from common law countries use parts of their proceeds from an equity issuance to redeem debt and to rebalance their capital structure. These findings are consistent with a time‐varying adverse selection explanation of firms' financing decisions.

Information asymmetry and the value of cash

This study investigates the market value of corporate cash holdings in connection with firm-specific and time-varying information asymmetry. Analyzing a large international sample, we test two opposing hypotheses. According to the pecking order theory, adverse selection problems make external financing costly and imply a higher market value of a marginal dollar of cash in states with higher information asymmetry. In contrast, the free cash flow theory predicts that excessive cash holdings bundled with higher information asymmetry generate moral hazard problems and lead to a lower market value of a marginal dollar of cash. We use the dispersion of analysts’ earnings per share forecasts as our main measure of firm-specific and time-varying information asymmetry. Extending the valuation regressions of Fama and French [Fama, E.F., French, K.R., 1998. Taxes, financing decisions, and firm value. Journal of Finance 53, 819–843], our results support the free cash flow theory and indicate that the value of corporate cash holdings is lower in states with a higher degree of information asymmetry.

Estimating the cost of executive stock options: Evidence from Switzerland

It is often argued that Black‐Scholes (1973) values overstate the subjective value of stock options granted to risk‐averse and under‐diversified executives. We construct a “representative” Swiss executive and extend the certainty‐equivalence approach presented by Hall and Murphy (2002) to assess the value‐cost wedge of executive stock options. Even with low coefficients of relative risk aversion, the discount can be above 50 per cent compared to the Black‐Scholes values. Regression analysis reveals that the equilibrium level of executive compensation is explained by economic determinant variables such as firm size and growth opportunities, whereas the pay‐for‐performance sensitivity remains largely unexplained. Firms with larger boards of directors pay higher wages, indicating potentially unresolved agency conflicts. We reject the hypothesis that cross‐sectional differences in the amount of executive pay vanish when risk‐adjusted values are used as the dependent variable.

Corporate cash holdings: Evidence from Switzerland

This paper investigates the determinants of cash holdings for a comprehensive sample of Swiss non-financial firms between 1995 and 2004. The median Swiss firm holds almost twice as much cash and cash equivalents as the median US or UK firm. Our results indicate that asset tangibility and firm size are both negatively related to corporate cash holdings, and that there is a non-linear relationship between the leverage ratio and liquidity. Dividend payments and operating cash flows are positively related to cash reserves, but we cannot detect a significant relationship between growth opportunities and cash holdings. Most of these empirical findings, but not all of them, can be explained by the transaction costs motive and/or the precautionary motive. Analyzing the corporate governance structures of Swiss firms, we document a non-linear relationship between managerial ownership and cash holdings, indicating an incentive alignment effect and an opposing effect related to increasing risk aversion. Finally, our results suggest that firms in which the CEO simultaneously serves as the COB hold significantly more cash.

What determines the speed of adjustment to the target capital structure?

A dynamic adjustment model and panel methodology are used to investigate the determinants of a time varying target capital structure. Because firms may temporarily deviate from their target capital structure in the presence of adjustment costs, the adjustment process is also endogenized. Specifically, we analyse the impact of firm-specific characteristics as well as macroeconomic factors on the speed of adjustment to the target debt ratio. The sample comprises a panel of 90 Swiss firms over the years from 1991 to 2001. We document that faster growing firms and those that are further away from their optimal capital structure adjust more readily. The results also reveal interesting interrelations between the adjustment speed and well-known business cycle variables. Most important, the speed of adjustment is higher when the term spread is higher and when economic prospects are good.

An integrated framework of corporate governance and firm valuation

Recent empirical research shows evidence of a positive relationship between the quality of firm‐specific corporate governance and firm valuation. Instead of looking at one single corporate governance mechanism in isolation, we construct a broad corporate governance index and apply five additional variables related to ownership structure, board characteristics, and leverage to provide a comprehensive description of firm‐level corporate governance for a representative sample of Swiss firms. To control for potential endogeneity of these six governance mechanisms, we develop a system of simultaneous equations and apply three‐stage least squares (3SLS). Our results support the widespread hypothesis of a positive relationship between corporate governance and firm valuation.

Long-run performance of initial public offerings: The evidence from Switzerland

Schmalenbach Business Review | 07/2005
We examine the underpricing and long-term performance of a broad set of Swiss IPOs from 1983 to 2000. The average market adjusted initial return is 34.97%. Our results support the ex ante uncertainty hypothesis, the signalling hypothesis and, to some extent, the market cyclicality hypothesis as possible explanations for the underpricing phenomenon on the Swiss IPO market. We also find evidence for lower initial returns under increased competition among investment banks, and more accurate pricing when book-building is used. To accurately measure the long-term performance of Swiss IPOs, we use a variety of different methods and adjust for possible biases. In contrast to previous findings for the U.S., we do not find a significant drop or strong continuous underperformance of Swiss IPO stock prices in the aftermarket. If there was any evidence for underperformance at all, Swiss IPOs show poor returns only in the very long-run after 48 months of trading.
