Given a process with independent increments X (not necessarily a martingale) and a large class of square integrable r.v. H = f(X T ), f being the Fourier transform of a finite measure μ, we provide a direct expression for Kunita-Watanabe and Föllmer-Schweizer decompositions of H. The...

Are mergers and acquisitions significant events that develop informativeness? Is the informativeness process the same in different countries? Looking only at cumulative abnormal returns (CARs) is insufficient and the results are sometimes contradictory. To answer to these questions we use the...

We examine how ownership concentration and the separation of ownership and control affect market liquidity in France. We find that firms with a large insider blockholder exhibit significantly lower liquidity. Different methods of concentrating control affect liquidity in different ways. Pyramid...

We examine how ownership concentration and the separation of ownership and control affect secondary-market liquidity in France. We find that firms with a large insider blockholder exhibit significantly lower liquidity. However, different methods of enhancing control affect liquidity in different...

Having been introduced in the European Union and in many other countries, the equal opportunity rule is seen as protecting investors in the event of a transfer of control. This rule should be analyzed in a context of appropriation of private benefits between the new controlling shareholders and...

The equal opportunity rule is seen as protecting investors in the event of a transfer of control. In order to better analyze the consequence of such a rule, we need to account for the information asymmetry that exists between new controlling shareholders and outside investors with private...

The aim of this study is to highlight the characteristics of corruption and non-academic behaviour in higher education. Using data series recorded at a representative student sample we emphasise causal relationships between certain components of corruption and aspects of academic behaviour in...

The assumption of linearity is implicitly accepted in the process which generates a time series condition submitted to a ARIMA. That is why, in this paper, we shall discuss the research of long memory in the processes: the fractional ARIMA models, denoted as ARFIMA, where d and D, the degree of...

This Bayesian modeling book is intended for practitioners and applied statisticians looking for a self-contained entry to computational Bayesian statistics. Focusing on standard statistical models and backed up by discussed real datasets available from the book website, it provides an...

In this paper we derive adaptive non-parametric rates of concentration of the posterior distributions for the density model on the class of Sobolev and Besov spaces. For this purpose, we build prior models based on wavelet or Fourier expansions of the logarithm of the density. The prior models...
