Outline
• Equal opportunities: approaches• Equal opportunities: problems• Another perspective: freedom• Respecting preferences• Issues in implementation
![Page 3: Measuring justice and development: Providing opportunities or respecting preferences](https://reader036.vdocument.in/reader036/viewer/2022082804/547a10915906b516358b461f/html5/thumbnails/3.jpg)
Equal opportunities: approaches
• Pragmatic approach (Roemer, World Bank): average outcome by origin – = disparity measurement, standardization
• Genuine opportunities approach (Sen, Cohen, Roemer): capability sets, access to advantage– Key element: genuine choice
• Resource approach (Rawls, Dworkin): generic resources, offered for use according to preferences– Criticized for fetishizing resources and preferences
![Page 4: Measuring justice and development: Providing opportunities or respecting preferences](https://reader036.vdocument.in/reader036/viewer/2022082804/547a10915906b516358b461f/html5/thumbnails/4.jpg)
Equal opportunities: approaches
• The reward problem: what should opportunities look like? Flat or steep?– Liberal approach: no intervention by the
government, no redistribution when inequalities are due to responsibility
– Utilitarian approach: zero inequality aversion, therefore give more to those with greater marginal utility (if they are responsible for it)

Equal opportunities: problems
• Anti-solidarity attitude, moralizing, self-righteous
• What is genuine choice? Individuals are influenced in so many ways
• Does EOp therefore reduce to equality of outcome?
• Yes – but what outcome?

Another perspective: freedom
• The bright side of opportunities: freedom• Should not be fetishized but is important and
attractive (across all cultures)• Does not justify focus on opportunities rather
than achievement, but is a component of well-being
• Concretely? Take account of people’s goals in life, their values, preferences (including on how much choice they want)

Respecting preferences
• Is it possible? Arrow’s theorem suggests not• Interpersonal comparisons are the key
ingredient of social evaluation• This is not an empirical issue, but a fairness
issue: who deserves greater priority?

Illustration: equivalent income
• Life = (income , quality of life)• Quality of life : denoted QoL• Principle 1: respect preferences on Life• Principle 2 (fairness): When QoL = QoL*, the
richer are better off• Theorem: Under these principles, people must
be compared in terms of equivalent incomes:(income , QoL) as good as (Eq.Inc. , QoL*)

Illustration: equivalent income
• Measure of social welfare:
Average Equivalent Income x( 1 – Inequality index on
Eq.Inc.)
• The inequality index embodies priority for the worst-off

What are people’s preferences ?
• Sources of information:– Revealed preferences– Stated preferences– Subjective well-being regressed on objects of
preferences• What are “authentic” preferences ?– Social conventions, social pressure– Behavioral phenomena (esp. for intertemporal
and risk issues)
![Page 13: Measuring justice and development: Providing opportunities or respecting preferences](https://reader036.vdocument.in/reader036/viewer/2022082804/547a10915906b516358b461f/html5/thumbnails/13.jpg)
Making it relevant
• How to extend the measure to different levels of development?– OECD: unemployment and life expectancy– Other studies: also leisure, family size– What about basic health care, basic public goods, safe water…
• Incorporate important social issues that are seldom measured:– Status– Autonomy at work (workers)– And at home (gender)– Freedom of movement and ideas– Quality of social networks

Conclusion
• Opportunities: better than nothing but potentially misleading
• Identifying and respecting preferences may be more promising: why do people rebel?
• Democratizing measures of social progress: not by cheap participatory forums, but by seeking to cater to people’s values and goals
