A Global Analysis of of Imperfect Competition in the Banking Systems and the Latest Israeli Regulation Dealing with Market Failures. ACES Working Paper No. 3, 2007

The high concentration of the banking sector is a cross-border phenomenon that has high impact on local and global economies. This paper's main goal is to analyze the factors that impact concentration in the banking systems around the globe. The innovation of this paper is that we combined economic, "economic environment", and culture variables as explanatory variables for this analysis. We found among other things that regulation in the banking system is helpful in order to keep it competitive. We also found that when the society has more individual values rather than collective ones, its banking sector is less concentrated. In the second part of the paper we focused on the Israeli case, showing that although recent indicators of the Israeli banking system indicate a higher level of concentration and lower level of competition, it seems that the recent trend is moving toward less concentration and higher competition.

Dealing with the Fallout: West Germany's Response to the Solange Decision (1974). ACES Working Papers, 2011

The European Union's powerful legal system has proven to be the vanguard moment in the process of European integration. As early as the 1960s, the European Court of Justice established an effective and powerful supranational legal order, beyond the original wording of the Treaties of Rome through the doctrines of direct effect and supremacy. Whereas scholars have analyzed the evolution of EU case law and its implications, only very recent historical scholarship has examined how the Member States received this process in the context of a number of difficult political and economic crises for the integration process. This paper investigates how the national level dealt with these fundamental transformations in the European legal system. Specifically, it examines one of the Union's most important member states, the Federal Republic of Germany. Faced with a huge number of cases dealing with European law, German judges dealt with the supremacy of European law very cautiously, negotiating between increasingly polarized academic, public and ministerial debates on the question throughout the 1960s. By the mid 1970s, the German Constitutional Court famously limited the power of the ECJ in its Solange decision (1974). This was an expression of a broader discourse in Germany from 1968 onwards about the qualitative nature of democracy and participation in public life and was in some aspects a marker, at which the German elites felt comfortable expressing the value of their national constitutional system on the European stage. This paper examines the political, media and academic build up and response to the Constitutional Court's decision in the 1970s, arguing that the national "reception" is central to understanding the dynamics and evolution of European Union legal history.

The New EU Criminal Law Competence in Action: The Proposal for a Directive on Criminal Sanctions for Insider Dealing and Market Manipulation. IES WORKING PAPER 5/2013

The aim of this paper is to analyse the proposed Directive on criminal sanctions for insider dealing and market manipulation (COM(2011)654 final), which represents the first exercise of the European Union competence provided for by Article 83(2) of the Treaty on the Functioning of the European Union. The proposal aims at harmonising the sanctioning regimes provided by the Member States for market abuse, imposing the introduction of criminal sanctions and providing an opportunity to critically reflect on the position taken by the Commission towards the use of criminal law. The paper will discuss briefly the evolution of the EU’s criminal law competence, focusing on the Lisbon Treaty. It will analyse the ‘essentiality standard’ for the harmonisation of criminal law included in Article 83(2) TFEU, concluding that this standard encompasses both the subsidiarity and the ultima ratio principles and implies important practical consequences for the Union’s legislator. The research will then focus on the proposed Directive, trying to assess if the Union’s legislator, notwithstanding the ‘symbolic’ function of this proposal in the financial crisis, provides consistent arguments on the respect of the ‘essentiality standard’. The paper will note that the proposal raises some concerns, because of the lack of a clear reliance on empirical data regarding the essential need for the introduction of criminal law provisions. It will be stressed that only the assessment of the essential need of an EU action, according to the standard set in Article 83(2) TFEU, can guarantee a coherent choice of the areas interested by the harmonisation process, preventing the legislator to choose on the basis of other grounds.
