Competence Centre COIN

What we doSupport to EU Services (> 40 indices & scoreboards)E.g., Social Scoreboard for the European Pillar of Social Rights (26/04/2017; CAB Juncker), Cultural and Creative Cities Monitor (06/07/2017; Commissioner Navracsics)

Collaborations with international partners (> 100 audits)E.g., Global Innovation Index (INSEAD, WIPO), Commitment to Reducing Inequality Index (Oxfam), Financial Secrecy Index (Tax Justice Network)

Methodology Jointly with the OECD quality control framework (conceptual coherence, multivariate analysis, sensitivity analysis, multi-criteria decision analysis, statistics and policy)

Training & Community of Practice on Composite Indicators and Scoreboards 5-9 November 2018, Ispra, Italy (16th Training – and 3rd CoP)

Community of Practice on Composite Indicators and Scoreboards

Discussion Topics• Fairness, Inequality and Poverty• Social Rights & Social Trust• Resilience & Risk Management• Sustainable Development & Sustainable

Governance

• Education & Skills• Ageing societies & Migration• Innovation & Digital Transformation• Competitiveness & Attractiveness

▶ How should indices and scoreboards be used for policy and what should be avoided?▶ How can indices and scoreboards be communicated to the wider public?

Developing an index...

Indicators as neutral metrics

=> Descriptive

Trigger action by comparison

=> normative

20

The power of numbers

Numbers as targets: strong advocacy tool- See the case of the Millennium Development Goals (MDGs)

“While quantification is the key strength of global goals, it alsoinvolves simplification, reification and abstraction, which havefar-reaching implications for redefining priorities”Setting MDG goals/targets influenced policy priorities and hadnormative effects on development discourses;All MDG goals/targets “led to unintended consequences indiverting attention from other important objectives and reshapingdevelopment thinking”

(Fukuda-Parr, S., Yamin, A.E., Greenstein, J., 2014)

21

Indicators for Policy

Surge of indicators of policy• Internationalization & globalization (need for comparison)• Calls for accountability (the “audit explosion” – Power, 1994)

• legitimize interventions (ex ante) & demonstrate success (ex post)

• Indicators offer de-personalized accounts on the state of the world to allow for rational decisions to change the world for the better (Rottenburg and Merry, 2015)

=> Aim to provide unbiased, comparable information on a single phenomenon of interest for different units

BUT: quantification involves simplification=> Normative choices

22

Indicators are shaped by policy needs & discourseIndicators, in turn, influence policy discourse

Indicators are embedded in a socio-political context• Indicators & indicator frameworks are value laden; reflect policy discourse

(Godin, 2002)

• Indicator developers & users better be aware of consequences:• The “agora model” (Barré, 2001, 2010)

indicators are “debating devices” – it’s the process that matters!• Honest broker (Pielke, 2007)• “Indicators in the wild” – open up scope of data & expertise, process, framing

of problems (Rafols, 2017)

23

Composite Indicators

Advantages:

• Support decision makers by summarizing complex or multi-dimensional issues

• Provide the “big picture”, highlight common trends

• Measure a latent phenomenon that is not directly measureable

• Attract public interest by benchmarking

Pitfalls:

• Offer misleading, non-robust policy messages if they are poorly constructed or misinterpreted

• May invite politicians to draw simplistic policy conclusions

• Easier to “manipulate” than individual indicators; the selection of sub-indicators and weights could be the target of political challenge

The development process is crucial: it helps• Better understand how a system functions• Identify latent dimensions, redundancies or

trade-offs between components

The Quality of Composite Indicators

“Composite indicators sit between analysis and advocacy, but quality discriminates the plausible from the rhetorical” (Saltelli, 2007)“Composite indicators sit between analysis and advocacy, but quality discriminates the plausible from the rhetorical” (Saltelli, 2007)

Advocacy

Analysis

Quality

Codified and continuously refined methodology• The OECD-JRC Handbook (JRC-OECD, 2008)• Audits – robustness and sensitivity

analyses (i.e. Saisana et al, 2011; Paruolo et al, 2013)

25

3 Auditingcomposite index frameworks

26

What is the purpose of auditing indicators?

• Test for statistical coherence• Are the conceptual and statistical frameworks aligned?• Is the structure statistically justified? • Are all indicators sufficiently driving index scores?

(accounting for information loss)

• Test for robustness and sensitivity • How do modelling assumptions influence results?

requests for JRC audits by international partners (UN, UNICEF, Tax Network, WEF, INSEAD, WIPO, UN-IFAD, FAO, Harvard U., Yale U., Columbia U., Cornell U.)

The EC JRC is an in-house science centre providing technical advice to a variety of projects throughout Europe. As part of that mission it is also an expert reviewer of project methodologies, says SiddharthBannerjee, Nesta project lead for the EDCI. It’s important to be rigorous about methodology. It’s how bias can sneak in when not expected,” he adds. “The EC JRC may not be well known outside certain circles, but it is the ultimate indicator of what a composite index looks like.”

Examples: Requests for JRC audits

• Assess if few indicators dominate the framework

(rindicator,index>0.95)

• Assess if indicators behave as “noise” in the framework

(-0.3<rindicator,index<0.3)

• Assess if indicators are negativelyrelated to the index

(rindicator,index<-0.3)

30 JRC-COIN © | Step 7: Statistical Coherence

• Ideally, an indicator correlates more with its own dimension than with others

• See e.g., Sustainable Society Index, 2012

Are the indicators in the right dimension?

31 JRC-COIN © | Step 7: Statistical Coherence

• Similarly, sub-pillars are ideally relatively more correlated to their own pillar than others

• See e.g. Global Innovation Index, 2017

• Positive, strong correlation between Sub-pillar and pillar

Are the indicators in the right dimension?

32

• …• Assess if indicators statistically fit

better under different dimensions than those in the framework

• Assess if dimensions should be merged or split

• Assess if bias has been introduced in the index (e.g., due to population size, population density, GDP)

How important are underlying assumptions?• Identify key modelling choices• Test their impact on the final composite

scores and rankings

Assumptions influence outcome

(Source: Hardeman and Vertesy, 2015)

36

• Identify which uncertainties are more crucial in determining the final classification

• Explain why certain countries notably improve or deteriorate their relative position given the assumptions

• Robustness ≠ Quality

Robustness & Sensitivity

COIN helps to ensure that composite indicators are …

developed sensibly and used responsibly.

‘Sensible development’ of a composite indicator implies a quality control process based on both conceptual and statistical considerations.

‘Responsible use’ calls for care in drawing conclusions and recommendations without taking into account the conceptual context in which composite indicators were developed.

Indices are powerful advocacy tools
