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

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 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.

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

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.

Investor sentiment and initial coin offerings

Wolfgang Drobetz, Paul P. Momtaz, Henning Schröder
Journal of Alternative Investments | 04/2019
The authors examine to what extent the market for initial coin offerings (ICOs) is driven by investor sentiment. Their results, based on a comprehensive set of sentiment and coin price data, suggest that the ICO market is driven by crypto-related sentiment, but is almost unrelated to general capital market sentiment. Among the crypto-related sentiment, social media channels, rather than traditional news channels, are the main source of investor sentiment. The authors find that ICO firms exploit “windows of opportunity” and avoid periods of negative sentiment. Coins listed during periods with negative investor sentiment generate negative returns in the short run. Moreover, returns to investors on the first day of trading predict long-run returns up to six months.

Performance measurement of crypto funds

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.

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

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.

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

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.
