Much useful discussion but some common elements

Much useful discussion - but some common elements

New Measure “BIPOL”

Representative Agent empirical strategy

GNI per capita and life expectancy

Global & Sub-Saharan Africa

Identify permanently different groups

Multiple dimensions of permanent advantage/disadvantage

Objective – make tools to explain/predict subjective attitudes to structured inequality

“False Consciousness Problem”


Comments on the anderson trilogy boats and tides and trickle down theories polarization of the poor examin

  • Objective: subjective consciousness

    • “the intensity or within group association is represented by the averaged heights of the modal points fp(xmp) and fr(xmr) following the intuition that the greater the mass within a region close to the modal point, the greater will the height of the pdf be. That the mean normalized Euclidean distance between the two modal points represents the sense of alienation between the two groups is somewhat more obvious.”

    • BUT no attempt to check – e.g. using ISSP data

    • Multiplication presumes Density x Distance = Index


Multiplicative form assumes averaged modal density distance

Multiplicative form assumes (- α % averaged modal density) = (+ α % distance)


In chosen example mode is informative sub distributions are unimodal well behaved

In Chosen Example, Mode is informative (sub-distributions are unimodal & well-behaved)


But easy to find alternative examples

But easy to find alternative examples


How likely is it that the mode is uninformative

How likely is it that the mode is uninformative?

Micro-data

Continuity, multiple influences usually a good assumption

Labour market segmentation literature argued structurally different processes within segments

Sometimes – discrete categories => qualify for benefits program => same formula => same income

E.g basic pension minimum for elderly, veteran’s benefits

Representative Agent Macro

Within country inequality assumed = zero

Cross-country results dominated by country size effect

What does Nigeria’s GNI per capita say about subjective attitudes or objective welfare/development in Tanzania?


Sub saharan africa mode nigeria gni rises and falls with oil price

SUB-SAHARAN AFRICA: MODE = NIGERIAGNI – RISES AND FALLS WITH OIL PRICE


To measure subjective consciousness or objective deprivation

To Measure:Subjective Consciousness or Objective Deprivation?

Subjective Consciousness – worth measuring as predictive of political economy

“Class consciousness” / “False consciousness” ?

Objective Deprivation – long ethical tradition presumes that conditioning to acceptance of deprivation should be disregarded by an impartial informed observer

Unpalatable Implication here:

“in this case, unlike FGT3, inequality amongst the poor has a positive rather than a negative connotation embodying the notion that lack of identification amongst the poor lowers perceived poverty”

LO: ?????????


Time trajectories life chances insecurities

Time – Trajectories, Life Chances & Insecurities

“Underlying the measures is the supposition that a society contains two classes of people the poor and the non-poor each observably characterized by measurable processes they experience.”

Permanent Disadvantage, along multiple dimensions, is focus

But class membership is immutable

Paradigm example: Caste in India

So why might the (securely) non-poor do anything?

Policy Motivation: Charity / Ethical Concern


Or is poverty the state of being deprived perhaps on multiple dimensions

OR:Is poverty the state of being deprived (perhaps on multiple dimensions)?

Structurally different odds of entry / exit to state of poverty + uncertainty

Life chances => trajectory of well-being => anxiety about future

Insecurity about future – not just the currently most deprived

Paradigm examples: Sub-Saharan Africa HIV/Aids; Fistula

So why might the (currently lucky) non-poor do anything?

Policy Motivation:

Perceived common identity, commonality of risk historically enabled social insurance, social wage of welfare state

“Framing Matters” – a crucial choice of poverty research
