The Role of Investment Banking in M&A Operations: Empiric Pre and Post Lehman Evidence
No full textThe role of investment banks in M&A operations is analyzed on the basis of empiric evidence. In particular, to point out the variations in the impact of the certification effect which can be ascribed to investment banks, the relationship between the value created for the shareholders in companies involved in special underwriting operations and the reputation of the banks appointed to act as advisors is examined. The analysis, which uses an original measuring system in order to assess and classify the reputation variable, focuses on transactions that have taken place between listed companies in two time frames, symmetrical to each other, specifically pre and post the Lehman Brothers bankruptcy. The total sample is composed of 229 transactions, divided into 161 and 68 observations, respectively pre and post Lehman. The result is that in the post Lehman period, unlike the preceding time frame, for which no significant empiric evidence is found, the wealth of the shareholders (of both targets and acquirers) is significantly influenced by the reputation of the investment banks which have acted as advisors. This indicates that, subsequent to the shock of the Lehman Brothers collapse, the certifying effect of the investment banks takes on an important role in the shareholders' choice

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Does Corporate Governance really matter for firms performance? Evidence from Italian IPOs market
No full textDuring recent years, corporate governance has received an increasing attention in the academic debate due to several scandals in financial world and consequent changes in the regulatory framework. Through this paper, we aim to take part in the stimulating debate about the relation between corporate governance and performance. Previous literature on this topic provided a solid theoretical framework for our research. This paper contributes to this investigation with an analysis of the Italian market, by the examination of the relation between the market performance of Italian IPOs and their governance structure. In particular, we find evidence of a positive relation between governance, which we measured by a new and original governance index made by 40 provisions, and IPOs performance occurred in the Italian market during period 1998-2008
