"The European Securities Industry. Further Evidence on the Roadmap to Integration"
No full textThe integration of the European securities market is one of the most important and ambitious steps of the making of a unified financial system, particularly since the achievement of the monetary union. The paper contributes to the debate on the integration and shows why the issue of costs and competition between different trading and post-trading systems is the key point of future integration. In particular, the analysis starts with the roadmap set by the European Commission and the evolution of the regulatory approach towards the integration of the trading and post-trading sectors. After the roadmap, in the paper we review the results of the research on the main issues related to the integration of securities markets and we comment on the present situation, with particular references to the alliances and mergers between the main actors of the trading and post-trading business. In addition, we present some original measures of the explicit costs of trading for all main European exchanges, adopting a bottom-up approach, which allows to compare the prices paid by different investors for different sizes of trades. This comparison shows that the ranking of exchanges by level of prices varies, according to the trade size taken into account. This on the one hands makes more difficult the emergence of the most efficient and on the other hand has anti-competitive effects, in particular for non domestic traders. Integration becomes therefore more difficult. To complement the analysis on trading costs, we also briefly review the debates on fragmentation of different European post-trading systems. The paper concludes with some policy implication
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
