Transparency of ownership and control in Germany

We first analyze legal provisions relating to corporate transparency in Germany. We show that despite the new securities trading law (WpHG) of 1995, the practical efficacy of disclosure regulation is very low. On the one hand, the formation of business groups involving less regulated legal forms as intermediate layers can substantially reduce transparency. On the other hand, the implementation of the law is not practical and not very effective. We illustrate these arguments using several examples of WpHG filings. To illustrate the importance of transparency, we show next that German capital markets are dominated by few large firms accounting for most of the market’s capitalization and trading volume. Moreover, the concentration of control is very high. First, 85% of all officially listed AGs have a dominant shareholder (controlling more than 25% of the voting rights). Second, few large blockholders control several deciding voting blocks in listed corporations, while the majority controls only one block

Corporate Governance and Control

Corporate governance is concerned with the resolution of collective action problems among dispersed investors and the reconciliation of conflicts of interest between various corporate claimholders. In this survey we review the theoretical and empirical research on the main mechanisms of corporate control, discuss the main legal and regulatory institutions in different countries, and examine the comparative corporate governance literature. A fundamental dilemma of corporate governance emerges from this overview: regulation of large shareholder intervention may provide better protection to small shareholders; but such regulations may increase managerial discretion and scope for abuse.

"Excess Volatility" and the German Stock Market, 1876-1990

This paper uses long-run real price and dividends series to investigate for the German stock market the questions asked of the U.S. market by Shiller (1989). It tries to determine in what periods and to what degree the German stock market has also possessed excess volatility' in the past century. It finds no evidence of excess volatility in the pre-World War I German stock market. By contrast, there is some evidence of excess volatility in the post-World War II German stock market. The role played by the German Grosbanken in the pre-World War I stock market might be the cause of low comparative volatility of German stock indices before 1914.

Bank ownership structure, regulations and risk-taking : evidence from commercial banks in Pakistan

This paper conducts the first empirical assessment of the theories concerning the influence of ownership structure on bank risk-taking in the presence of regulations in Pakistan. The sample used in this paper comprises a panel data of 26 banks in Pakistan, for the period from 2000 to 2014. The analysis provides evidence that increase in ownership concentration leads to an increase in bank risk-taking. Managerial ownership is associated with high risk-taking at low and high levels of managerial ownership while at intermediate level, managerial ownership has negative impact on bank risk-taking. Different types of ownership of banks in Pakistan have different impact on risk-taking. While government, family and institutional ownership have a positive impact on bank risk-taking, foreign own- ership has a negative impact on bank risk-taking. Furthermore, the results show that capital regulations are important in influencing bank risk-taking with regard to higher ownership concentration. The findings of this paper suggest that the relation between bank risk-taking and capital regulations typically depends on the type of ownership.info:eu-repo/semantics/publishedVersio

f0(980) production in inelastic pp collisions at s = 5.02 TeV

The measurement of the production of f0(980) in inelastic pp collisions at sqrt(s) = 5.02 TeV is presented. This is the first reported measurement of inclusive f0(980) yield at LHC energies. The production is measured at midrapidity, |y| pi+pi- hadronic decay channel using the ALICE detector. The pT-differential yields are compared to those of pions, protons and ϕ mesons as well as to predictions from the HERWIG 7.2 QCD-inspired Monte Carlo event generator and calculations from a coalescence model that uses the AMPT model as an input. The ratio of the pT-integrated yield of f0(980) relative to pions is compared to measurements in e+e- and pp collisions at lower energies and predictions from statistical hadronisation models and HERWIG 7.2. A mild collision energy dependence of the f0(980) to pion production is observed in pp collisions from SPS to LHC energies. All considered models underpredict the pT-integrated 2f0(980)/(pi+ + pi-) ratio. The prediction from the canonical statistical hadronisation model assuming a zero total strangeness content of f0(980) is consistent with the data within 1.9σ and is the closest to the data. The results provide an essential reference for future measurements of the particle yield and nuclear modification in p–Pb and Pb–Pb collisions, which have been proposed to be instrumental to probe the elusive nature and quark composition of the f0(980) scalar meson

Neutral to charged kaon yield fluctuations in Pb – Pb collisions at sNN=2.76 TeV

We present the first measurement of event-by-event fluctuations in the kaon sector in Pb – Pb collisions at √sNN = 2.76 TeV with the ALICE detector at the LHC. The robust fluctuation correlator νdyn is used to evaluate the magnitude of fluctuations of the relative yields of neutral and charged kaons, as well as the relative yields of charged kaons, as a function of collision centrality and selected kinematic ranges. While the correlator νdyn[K+, K− ] exhibits a scaling approximately in inverse proportion of the charged particle multiplicity, νdyn[K0 S , K± ] features a significant deviation from such scaling. Within uncertainties, the value of νdyn[K0S , K± ] is independent of the selected transverse momentum interval, while it exhibits a pseudorapidity dependence. The results are compared with HIJING, AMPT and EPOS–LHC predictions, and are further discussed in the context of the possible production of disoriented chiral condensates in central Pb – Pb collisions

Light (anti)nuclei production in Pb-Pb collisions at sNN=5.02 TeV

The measurement of the production of deuterons, tritons and 3 He and their antiparticles in Pb-Pb collisions at √s NN = 5.02 TeV is presented in this article. The measurements are carried out at midrapidity (|y| < 0.5) as a function of collision centrality using the ALICE detector. The pT -integrated yields, the coalescence parameters and the ratios to protons and antiprotons are reported and compared with nucleosynthesis models. The comparison of these results in different collision systems at different center-of-mass collision energies reveals a suppression of nucleus production in small systems. In the Statistical Hadronisation Model framework, this can be explained by a small correlation volume where the baryon number is conserved, as already shown in previous fluctuation analyses. However, a different size of the correlation volume is required to describe the proton yields in the same data sets. The coalescence model can describe this suppression by the fact that the wave functions of the nuclei are large and the fireball size starts to become comparable and even much smaller than the actual nucleus at low multiplicities
