Social Connections and Information Leakage: Evidence from Target Stock Price Run-up in Takeovers

Abstract
Does information leakage in a target's social networks increase its stock price prior to a merger announcement? Evidence reveals that a target with more social connections indeed experiences a higher pre-announcement price run-up. This effect does not exist during or after the merger announcement, or in windows ending two months before the announcement. It is more pronounced among targets with severe asymmetric information, and weaker when the information about the upcoming merger is publicly available prior to the announcement. It is also weaker in expedited deals such as tender offers.

Herding Behavior and Systemic Risk in Global Stock Markets
Iftekhar Hasan, Radu Tunaru, Davide Vioto
Journal of Empirical Finance,
September
2023
Abstract
This paper provides new evidence of herding due to non- and fundamental information in global equity markets. Using quantile regressions applied to daily data for 33 countries, we investigate herding during the Eurozone crisis, China’s market crash in 2015–2016, in the aftermath of the Brexit vote and during the Covid-19 Pandemic. We find significant evidence of herding driven by non-fundamental information in case of negative tail market conditions for most countries. This study also investigates the relationship between herding and systemic risk, suggesting that herding due to fundamentals increases when systemic risk increases more than when driven by non-fundamentals. Granger causality tests and Johansen’s vector error-correction model provide solid empirical evidence of a strong interrelationship between herding and systemic risk, entailing that herding behavior may be an ex-ante aspect of systemic risk, with a more relevant role played by herding based on fundamental information in increasing systemic risk.

Monetary Policy through Exchange Rate Pegs: The Removal of the Swiss Franc-Euro Floor and Stock Price Reactions
Gregor von Schweinitz, Lena Tonzer, Manuel Buchholz
International Review of Finance,
Nr. 4,
2021
Abstract
The Swiss National Bank abolished the exchange rate floor versus the Euro in January 2015. Using a synthetic matching framework, we analyze the impact of this unexpected (and therefore exogenous) policy change on the stock market. The results reveal a significant level shift (decline) in asset prices following the discontinuation of the minimum exchange rate. As a novel finding in the literature, we document that the exchange‐rate elasticity of Swiss asset prices is around −0.75. Differentiating between sectors of the Swiss economy, we find that the industrial, financial and consumer goods sectors are most strongly affected by the abolition of the minimum exchange rate.

Deutsche Lebensversicherer investieren nicht ausreichend in Start-ups
Die deutschen Lebensversicherer legen ihr Kapital bislang zu wenig in Aktien an und hemmen so die wirtschaftliche Dynamik. Eine Studie des Leibniz-Instituts für Wirtschaftsforschung Halle (IWH) legt nahe, dass der Gründerszene Risikokapital fehlt, um erfolgreiche Start-ups zu finanzieren. Grund dafür ist das Anlageverhalten potenzieller Investoren. IWH-Präsident Reint Gropp fordert Reformen, die die Finanzierung innovativer Ideen fördern.

Why Life Insurers are Key to Economic Dynamism in Germany
Reint E. Gropp, William McShane
IWH Online,
Nr. 6,
2020
Abstract
Young entrepreneurial firms are of critical importance for innovation. But to bring their new ideas to the market, these startups depend on investors who understand and are willing to accept the risk associated with a new firm. Perhaps the key reason as to why the US has succeeded in producing nearly all the most successful new firms of the 21st century is the economy’s ability to supply vast sums of capital to promising startups. The volume of venture capital (VC) invested in the US is more than 60 times that of Germany. In this policy note, we argue that differences in the regulatory and structural context of institutional investors, in particular life insurance companies, is a central driver of the relative lack of VC - and thereby successful startups - in Germany.

Abstract
Die „Gemeinschaftaufgabe ‚Verbesserung der regionalen Wirtschaftsstruktur‘ (GRW)“ repräsentiert das wichtigste Instrument der Regionalpolitik in Deutschland. Das Förderprogramm gewährt nicht-rückzahlbare Zuschüsse als Anteilsfinanzierung für Investitionsprojekte von Betriebsstätten (und Kommunen) im GRW-Fördergebiet. Die Festlegung des Fördergebiets erfolgt anhand eines aus verschiedenen Teilindikatoren zusammengesetzten Strukturschwächeindikators und eines von der Europäischen Union festgelegten Anteils der in Fördergebieten lebenden Bevölkerung. Verantwortlich für die Auswahl der geförderten Projekte ist das jeweilige Land, in dem das GRW-Projekt beantragt wird.

Why are some Chinese Firms Failing in the US Capital Markets? A Machine Learning Approach
Gonul Colak, Mengchuan Fu, Iftekhar Hasan
Pacific-Basin Finance Journal,
June
2020
Abstract
We study the market performance of Chinese companies listed in the U.S. stock exchanges using machine learning methods. Predicting the market performance of U.S. listed Chinese firms is a challenging task due to the scarcity of data and the large set of unknown predictors involved in the process. We examine the market performance from three different angles: the underpricing (or short-term market phenomena), the post-issuance stock underperformance (or long-term market phenomena), and the regulatory delistings (IPO failure risk). Using machine learning techniques that can better handle various data problems, we improve on the predictive power of traditional estimations, such as OLS and logit. Our predictive model highlights some novel findings: failed Chinese companies have chosen unreliable U.S. intermediaries when going public, and they tend to suffer from more severe owners-related agency problems.

Did the Swiss Exchange Rate Shock Shock the Market?
Manuel Buchholz, Gregor von Schweinitz, Lena Tonzer
Abstract
The Swiss National Bank abolished the exchange rate floor versus the Euro in January 2015. Based on a synthetic matching framework, we analyse the impact of this unexpected (and therefore exogenous) shock on the stock market. The results reveal a significant level shift (decline) in asset prices in Switzerland following the discontinuation of the minimum exchange rate. While adjustments in stock market returns were most pronounced directly after the news announcement, the variance was elevated for some weeks, indicating signs of increased uncertainty and potentially negative consequences for the real economy.
