Motivation • Problems with Expected Utility Theory • Challenges to National Income Measurement (work in UK and OECD) • Operationalising capabilities approach in high income countries
Limits to Gross National Product per capita • Ignores defensive expenditures • Ignores value of household work • Ignores differences in needs • Emphasises material affluence (eg ignores qol at work, rights violations) Measures monetary value of production or cost of consumption but measurement of human welfare could be improved GDP Satellite Accounts, Social Accounting Matrices (non-monetary indicators as complements) HDI More dimensions, breakdowns
Phase I (2000-2006) primary and secondary data devise methodology for capability assessment conduct national UK survey using OCAP explore some econometric issues associated with use of capability data Phase II (2006- extending applications of capabilities measurement (OCAP family) short form version (Glasgow) Spanish translation (Buenos Aires) further applications (e.g. mental health in Oxford, housing in social policy) analysis Capabilities Measurement Project (Summary to Date)
Some Early Work • Human Development Index • Schokkaert and van Ootegem (1990) • Enrica Chiappero Martinetti (1994, 2000) • Laderchi (1997) • Kuklys (2005) • Brandolini and D’Alessio (1999) “The purpose is to assess the operational content of the approach ie the empirical methods to measure functionings and capabilities…much of what one can do depends the available data….we discussed the practical difficulties of moving to capabilities and proposed to remain in the (refined) functionings space.” Source: Plenary paper given to the International Economics Association Congress, Buenos Aires
Theory (Sen 1985 pp11-4) ui = hi(.) ui is ‘happiness enjoyed’ hi (fi(c(xi))) xi is vector of commodities possessed by i c(.) converts commodity vector into vector of characteristics fi(.) reflects one pattern of use Fi “Qi represents the freedom a person has in terms of the choice of functionings, given his personal features Fi…and his command over commodities Xi.”
Theory (Sen 1985 pp11-4) ui = hi(.) ui is ‘happiness enjoyed’ hi (fi(c(xi))) xi is vector of commodities possessed by i c(.) converts commodity vector into vector of characteristics fi(.) reflects one pattern of use Fi “Qi represents the freedom a person has in terms of the choice of functionings, given his personal features Fi…and his command over commodities Xi.” Our approach 1. Elicit indicators of Qi, Ci,j where j = 1…60+ 2. Estimate lsi = hs(Ci,j) where s in hs is null or allows only partial heterogeneity
A. Anand and van Hees (2006) Question Types Achievements and Scope Perceived distribution of scope Domains Happiness Success Health Intellectual Stimulation Social Relations Environments Personal Integrity Overall Options Models Overall Options Satisfaction Individual Achievements
Questions • Generally, my life is happy (strongly agree...) • I feel the scope to seek happiness in my life is (very good…) c. The proportion of the population who have severely limited opportunities to seek happiness is (0-9%,…) a. I have satisfying social relations (strongly agree…) b. I feel the scope to form satisfying social relations in my life is (very good…) c. The proportion of the population who have severely limited opportunities to form satisfying social relations is (0-9%) a. I live a health life for my age (strongly agree…) b. I feel the scope to live a healthy life for my age is (very good…) c. The proportion of the population who have severely limited opportunities to live healthy lives for their age is (0-9%)
Some Conclusions Each achievement is a function of its respective capability Estimates of other capabilities are often anchored on own capabilities with notable exceptions Greatest scope: health/environment Least scope: social relations/personal integrity Issues to be Addressed • Sample Size • Secondary Data • Question Type
B. Anand Hunter and Smith (2005) Social Indicators Research Aim Explore links between satisfaction and capabilities using BHPS data
Econometric Approach s = a + bC + e s = a + bC + cP + e pjhat = sj-sjhat j=10 life domains s = a + bC + cPhat + e Hausman Wu Test for endogeneity: c=0
Adaptation Issues If Complete and Instantaneous ‘Goods’ would have no observable impact on life satisfaction There is some evidence of adaptation especially to improvements so capabilities which impact life satisfaction are only the utilitarian capabilities
Two Conclusions Person specific effects significant Secondary data exists but is sparse
AHRB Project to Measure Capabilities Research Question Can we measure capabilities across a wide spectrum of human domains within the conventions applicable to national household and social surveys?
Framework for Questions Nussbaum’s List Comprehensive Robust (similar to others) Don’t require universal claims Has normative grounding
Question Categories • Life • Bodily Health • Bodily Integrity • Senses Imagination and Thought • Emotions • Practical Reason • Affiliation • Nature • Leisure • Control over one’s Environment

4 Types of Capability Indicators Type 1. Opportunities Type 2. Abilities Type 3. Constraints Type 4. Functionings + Reasons/ Universality
Analyses • Sex/age differences + links to happiness for all Capabilities • Violent crime, gender inequalities, links to income, personality and life satisfaction • Health as a determinant of capability
Violent Crime, Gender Inequalities and Life Satisfaction Data • Past Experience/Future Expectations of domestic, sexual and other forms of assault • Safety in local area during day and night Analysis • Describe experience and differences between sexes • Correlations between all indicators • Examine causes of perceived future risk • Links between violence and life satisfaction • Particular link between domestic violence and income poverty
Health and Capability Poverty Data • Does health limit your daily activities for your age • All capabilities, life satisfaction and socio-economic covariates Analysis • Capability differences by health status • Capabilities as a function of health, income and personality (binary and ordered logit) • Capability profiles as a function of health income and personality (latent class)
Obesity and Opportunity Set Dynamics:From Rational Choice to a New Kind of Market Failure? • Technological Change • ‘Optimal Fattening’ • Social Norms • Obesogenic Environments as Capabilities we value negatively Competition Inappropriate Choice Sets Decision utilities ≠ experienced utilities or best interest utilities
Obesity and Opportunity Set Dynamics:From Rational Choice to Market Failure Initial Condition: S={a,b}, D/S={a}, aPb for all b Competition and new feasible set: S’={a,b1,b2}, D/S’={b1} (for axiomatics see Suzumura and Xu forthcoming) Result: Decision Utility ≠ Best Interest/Experienced Utility (Kahneman et al QJE 1997) Conclusion: Inappropriate Choice Sets can result from free individual choices + competitive markets (New Kind of Market Failure – applies also to debt)
Capabilities Measurement – Some Findings to Date It IS possible to measure capabilities… Some secondary data exists but more can be generated (our work identifies steps) Sen’s 3 key equations can be estimated Experienced utility (welfare) is highly multi-dimensional Capability Inequalities and heterogeneity (eg personality) can be found Health is strongly related to capability deprivation
Finally… Future plans: discrimination expand questions in leisure/nature/work expand sub-population coverage to make more detailed use of response categories (disability/reproductive choice/children) extend applications beyond England, Scotland and Argentina In health; extend EQ5 do work on access to care complete analysis of child development
