I shall firstly summarise M&F′s study and results in order to allow for an easier assessment of the situation. Subsequently, I shall depict the arguments against the application of power indices to an organisation such as the European Union and put them into perspective. In the third part of this essay, I shall then attempt to show that methods proposed as alternatives to power indices do not, in fact, offer any workable alternatives when analysing the EU-Council after enlargement, and conclude that power indices can provide an important approximation of a priori power distribution and do carry relevance in assessing the Council and especially in understanding the behaviour of actors when deciding on issues like the re-weighting of votes in the Nice Treaty.

Research Objectives and Core Themes
The primary objective of this paper is to evaluate whether power indices serve as a valid scientific instrument for measuring shifts in political influence within the EU Council of Ministers following the re-weighting of votes under the Treaty of Nice. The work critically examines the tension between quantitative a priori power index analysis and qualitative non-cooperative game theory.
- The utility and validity of power indices in EU decision-making structures.
- Critique of power index methodology versus spatial analysis.
- Impact of the Treaty of Nice on voting power distribution.
- The conceptual distinction between power, luck, and successful outcomes.
- The limitations of institutional modeling in the context of European integration.
Excerpt from the Book
2.1 Arguments against the applicability of power indices to the Council of Ministers
And this is not at all undisputed. According to Garrett & Tsebelis (G&T), power indices are fundamentally irrelevant, because they ignore the policy positions of actors. This usually results in an overestimation of power for actors with extreme preferences and an underestimation for more median actors, since determining power is rendered to be little more than a mathematical exercise. As an example one only needs to consider the relative average chances of the UK, with its often extreme policy positions, and for example France to assemble a winning coalition of member states in a vaguely mainstream policy area. Having the same number of votes, a simple a priori power index would give these as being equal as well, which seems unlikely when considering historical experience (however, when carefully looking at this specific example and what it is supposed to illustrate, it appears possible that different conceptions of the term “power” might cause these two understandings to somewhat pass each other by, something I will come back to further below).
G&T argue that, especially when dealing with an entity like the European Union, this inability of power indices to include policy preferences is crippling, since the complicated bargaining structures between the Council of Ministers, the European Parliament and the Commission, as well as agenda-setting powers in the various decision-making procedures, are in no way taken into account. Moreover, since all combinations of actors are considered to be equally likely, non-connected winning coalitions (NCCs) are counted as well, which is nonsensical in the context of the Council, as NCC-members do neither have the incentive nor the ability to exclude other actors with preferences that lie between their own extreme positions.
Summary of Chapters
1. The Council of Ministers – a power index analysis: This chapter introduces the decision rules for the Council, specifically focusing on the QMV procedure and the methodological criteria used to analyze voting power.
2. Applying power indices to the EU – a critique: This section investigates the limitations of power indices, specifically addressing the arguments that they fail to account for policy positions and institutional realities.
3. Are there alternatives?: This final analytical chapter compares power indices with spatial analysis, concluding that despite inherent flaws, power indices remain the most viable tool for assessing voting influence in the absence of complete empirical data.

Frequently Asked Questions
What is the core focus of this research paper?
The paper examines the validity of using mathematical power indices to quantify shifts in influence within the Council of Ministers, specifically in the context of the institutional changes brought about by the Treaty of Nice.
What are the primary themes discussed?
The study navigates through the methodology of measuring voting power, the critique of these methods by political scientists advocating for spatial analysis, and the practical utility of these tools in the complex environment of the European Union.
What is the central research question?
The central question is whether, given the complicated inter-institutional arrangements of the EU, power indices can effectively serve as a valid measure to assess changes in influence within the Council of Ministers.
Which scientific methodology is employed?
The author primarily utilizes an analytical critique of existing a priori power index models (such as Banzhaf and Penrose) and contrasts these with non-cooperative game theory and spatial modeling approaches.
What topics are covered in the main body of the work?
The main body details the QMV procedure, applies specific power index metrics to the post-Nice scenario, addresses academic critiques regarding policy preference blindness, and discusses the potential for alternative analytical methods.
Which keywords best characterize this work?
Key terms include Power Indices, Council of Ministers, Treaty of Nice, QMV, Voting Power, and Spatial Analysis.
How does the author define the difference between power and luck?
Following Barry, the author describes power as the ability to bring about an outcome through the exercise of capabilities, whereas luck is the probability of an outcome occurring without any active exertion by the actor.
Why does the author argue that power indices are still relevant despite criticisms?
The author concludes that because actors often lack perfect information about the policy preferences of others, power indices provide a necessary and realistic approximation for analyzing political influence before negotiations or practical outcomes are solidified.
