Theories of justice
and the measurement of well-being
Guillermo Alves – Matías Brum – Andrea Vigorito
Instituto de Economía
Universidad de la República - Uruguay
Motivation
•
Recent discussion on the dimensions to be considered for comparisons
across countries, held internationally (Sarkozy commision, UNDP, World
Bank, Foro Consultivo Mexico)
•
Availability of international indexes (Better Life Index, Human Development
Index, Human Opportunity Index)
•
Available measures consider different dimensions and use
aggregation procedures, leading to different country rankings
•
Main indexes (GDP, BLI, HDI) and measures exclude important items in
their calculation:
different
• Inequality (lacking in HDI until 2009, BLI soon)
• Agency/Autonomy (though UNDP has made attempts)
•
Uruguay: local discussion on how to measure the impact of the recent
redesign of the social protection system

V. Final comments
I. Main purposes
•
Drawing from the main contemporary approaches to justice and justice
theories, discuss which dimensions should be taken into account for wellbeing comparisons
•
For each approach, identify the informational basis needed in order to
make comparisons. This implies:
• Choosing relevant indicators
• Choosing a combination procedure for the indicators
•
Approaches covered in our paper:
Utilitarism, Welfarism, Libertarianism, Egalitarian liberalism (Rawls, Dworkin),
Equality of Opportunities (Roemer), Capabilities Approach (Sen)
•
Stress the importance of inequality as an important (even central)
feature to be taken into account when comparing countries
II. Principles underlying social indicators
•
Principles guiding the system (Atkinson et al, 2002)
•
Principles guiding individual indicators (Atkinson et al, 2002)
•
Databases to be considered
• Household , individual surveys microdata

•
Balance among the different dimensions
Consistency among components
Transparent and accessible for all systems
Levels of importance must be determined
Identify the essence of the problem and have a clear normative interpretation
Robust and statistically validated
Responsive to policy interventions but not subject to manipulation
Comparable at international standards
Timely and susceptible to revision
Required data should not impose a large burden to states or statistical offices
Firms and organizations microdata
National accounts system data
Administrative records, laws, decrees, norms
III.Theories of justice and the dimensions of
well-being: a proposal
III.1 Utilitarianism and Welfarism
• Both approaches base interpersonal comparisons on subjective
well-being
• Nevertheless, for a long time interpersonal comparisons carried
out in Economics used data on income or consumption
• Recently, subjective evaluation has been favoured by a stream of
the economics profession led by the new Economics of hapiness.
• Whereas Utilitarianism considers aggregate utility, Welfarism
considers also its inequality or dispersion.
III.1 Utilitarianism and Welfarism
Dimension
Subjective
Well-being
Objective wellbeing
•
•
Indicator
Happiness / Life satisfaction: % of individuals that declare being very
satisfied or satisfied with their lives
Adjustment among desires and their satisfaction: Life satisfaction by
domain and ranking carried out by interviewee
Perception of economic situation: % of individuals that perceive it as
good or very good
Wealth: Average and SD of a durable goods index.
Income: Per capita average household income. Gini index. Generalized
Lorenz curves.
Consumption: Per capita average expenditure and Gini index of per capita
expenditure.
Utilitarianism as sum of individual utility
Welfarism as inequality in utility
III.2 Libertarianism (Nozick)
• Assesses first generation civil and political rights, economic
freedom and property rights
• Regarding negative freedoms, egalitarian treatment relies in the
supression of all barriers to these freedoms
• Main dimensions considered under this approach are:
•
•
•
•
•
•
The warranty of fundamental freedoms
The vigency of a judicial system
Circulation freedom
Freedom of expression, asociation, right to strike and demonstrations
Economic freedom
Warranty of property rights
III.2 Libertarianism (Nozick)
Dimension
Indicator
Existence of an independent judicial power
Vigency of a judicial system
Productivity of the judicial power
Limits to economic freedom
Economic freedom index
Limits to expression freedom
Position in the international ranking of the Press freedom index
Warranty by the state of
fundamental freedoms
Existence of discriminatory laws against population groups
Tax burden
Interference of the government
Public expenditure in defense as % of public expenditure
in the economy
Social expenditure as a % of public expenditure
Presence of public monopolies
Limits to property rights
Existence of norms that limit property rights: taxes, assaults by
100.000 inhabitants
Limits to right to life
Homicide rates for 100.000 inhabitants
Limits to economic freedom
Laws or regulations against the right of association, demonstration or
citizen participation
III.3 Egalitarian Liberalism (Rawls)
• Rawls’ two justice principles establish the ground for comparisons
• The first principle implies that basic freedoms are above the rest of the
dimensions (lexicographic priority)
• The second principle is twofold: establishes two conditions that are
necessary for tolerance, and to prevent situations of social inequality:
- Equality of possibilities to access jobs and positions
- Difference principle: inequalities need to turn into a major benefit to the
less advantaged members of society.
• Dimensions: access to primary goods
- Social basis of self-respect
- Wealth
- Income
• Operationalization has many caveats:
- Identification of less advantaged groups
- Unidimensionality of disadvantage (based on income only)
- Tolerance to high inequality levels (without contradicting the
Difference Principle)

III.4. Roemer’s equality
of opportunity
• This approach distinguishes between circumstances (out of control
of the individual) and effort. Only inequality due to differences caused
by external circumstances is “unfair”.
The isolation of the portion of inequality due to external
circumstances is a difficult task as long as effort is correlated with
circumstances
 Recent attempts of operationalization include: i) ex-ante and expost approaches; ii) parametric and non parametric decompositions of
inequality (Ferrando, 2011)
• In this proposal we concentrate in providing indicators that can
approximate inequality of opportunity
 The selection of the relevant dimensions is a key issue, although it
has been less controvertial than in the capabilities approach
 The dimensions that have been currently used in empirical literature
are health, work, education and income
III.5 Capabilities approach
(Sen & Nussbaum)
This approach considerably broadens the informational basis used to
carry out interpersonal comparisons
Sen separates well-being (functionings and capabilities) and agency
 Within the CA, there are different positions in relation to the
dimensions to be considered in well-being and agency assessments.
Whereas Sen leaves this task to communities and researchers,
Nussbaum advocates for the definition of a list of universal combined
capabilities. Alkire and Robeyns also argue for the existence of a list
but not necessary the Nussbaum one.
This approach has significant operationalization problems

IV.2 The proposed dimensions and assessments of
well-being over time: some results for Uruguay
• Covering 2001-2008
• Data from our National Household Survey and from Latinobarometer
• Information missing / incomplete / unavailable for some years and/or
indicators: our paper makes a proposal regarding this missing data
• As expected, the different informational basis and indicators lead to
different stories regarding what happened in the period
• In some cases, even within an approach, different indicators evolve in
the opposite direction

V. Final Comments
• Based on previous research, we propose dimensions to carry
out comparisons consistent with the main contemporary
approaches to distributive justice
•
Broadening the informational basis entails significant
increases in the number of relevant indicators as well as on
data sources, and advances in the two fields are required
• Results are sensitive to the choice of dimensions and
indicators
• When operationalizating different conceptions
• In some cases philosophical differences tend to fade
• In others, approaches empirically overlap
V. Final Comments
• A large effort in data collection needs to be done in the fields
of agency and freedoms
• As long as household surveys are built on the basis of
traditional approaches to well-being, they need to broaden the
dimensions in which they broaden their informational basis.
Particularly relevant for developing countries
• Aggregate indicators or separate indicators? Since evolution
may be different and even in opposite direction, among other
reasons, we make our case for a disaggregate view
• Approaches to justice are embedded in indexes; inequality and
agency should not be left behind.
