Almost a decade ago,long before they won the Nobel Prize,Economists Abhijit Banerjee and Esther Duflo published 'Poor Economics'.The book was a runaway success and remains immensely relevant today.
'Poor Economics' is written simply and clearly -- not one
econometric model or Game Theoretic theorem in sight -- and argued convincingly
with solid data backup. For anyone concerned about the issue of poverty and all
that goes with it, the book is an essential read -- both educative and deeply
disturbing.
The authors begin by highlighting a seemingly obvious
but oft disregarded proposition -- to tackle a problem one needs to understand
it in painstaking detail. And if it involves human beings, one needs to get up
close and personal and understand the mind sets, the motivations and the basic
emotional drivers of the people involved. In practice, despite pious
protestations about the emergent need for poverty alleviation by both academics
and policy makers, poverty tends to be studied from a distance and the poor set
up as two-dimensional caricatures. ‘Ideology,
ignorance and inertia’ appear to be the key determinants of both theory and
policy and the result is that the outcomes are less than satisfactory, to say
the least.
Such trenchant criticisms are not simply a radical
rant of fringe looneys -- these are mainstream Ivy League economists and,
besides, they offer logical argument to counter ideological theories and also a practical method, the much hyped
Randomized Control Trials, to evaluate
policy measures. To top it all, they present an 18 country database
derived from field level studies to back up their conclusions.
The authors are suspicious of broad, simple and
sweeping solutions that promise to wipe out poverty in one fell swoop. They
insist that a more appropriate approach is to focus on particular issues in
specific environments and design policy measures after rigorous testing in the
field using RCT for validation. Randomized Control Trials, brilliantly borrowed
from the medical field, are best described in the authors’ words:
‘In an RCT…individuals or communities are randomly assigned to
different “treatments”— different programs or different versions of the same
program. Since the individuals assigned to different treatments are exactly
comparable (because they were chosen at random), any difference between them is
the effect of the treatment.’………
‘A single experiment does not provide a final answer on whether a program would universally “work.” But we can conduct a series of experiments, differing in either the kind of location in which they are conducted or the exact intervention being tested (or both).’
The authors don’t
confine themselves to general assertions; instead they examine a series of
poverty related issues ranging from nutrition, public health, primary and
secondary education to fertility and finance and throughout, the focus is on
the poor – their circumstances, their compulsions and deriving therefrom their
life decisions.
The process is simple
and immensely powerful—from grass roots investigation and interaction to
comprehensive understanding; from understanding to policy formulation; from
formulation to validation and from validation to implementation or acceptance
for implementation.
In every one of these
explorations one finds fascinating insights. One revealing conclusion relates
to ‘time inconsistency’ in human behaviour. Most humans tend to place a higher
value on present gratification as opposed to future gratification and this
impacts many decisions including those relating to present consumption versus
saving. “I’ll consume today and save tomorrow, definitely!” But that tomorrow
never comes. This tendency is aggravated when the future is both uncertain and
unpromising or frankly bleak and resources are obviously inadequate to make any
difference even in the medium to long run. Some of the seemingly ‘irrational’
consumption and savings decisions of the poor may well be very rational given
their circumstances!
The same logic applies
to a tendency to avoid the immediate inconvenience of standing in line for a
child’s vaccination today and postponing it to some undefined future occasion.
Even when the benefits of vaccination for future health of the child are known,
the immediate ’headache’ of getting it done is small but significant. But since
it is small it can be overcome with a slight ‘nudge’— a small but significant
incentive. This was tested and found effective -- a gift of a modest amount of
dal was enough to tilt the balance in favour of immediate vaccination instead
of postponing it in a study done in Udaipur district in Rajasthan.
A whole series of other
poverty related issues are examined by the authors. What are the consequences
of the ‘Elite Bias’ in primary education? Has the focus on the best and
brightest and the neglect of the rest in school education severely damaged
educational outcomes? Is cheap food through the public distribution system the
best way of dealing with poor nutrition amongst the poor or are there other
areas that should be focussed on? Why have the plethora of nationalized banks
not met the credit requirements of the poor? How come the money lender is still
important in their lives?
Are microfinance institutions the new miracle
cure for the credit requirements of the poor wannabe entrepreneur? A detailed
study of this issue reveals that while MFI’s do help significantly, the miracles
are few and far between. The rags to riches stories peddled by these
institutions are exceptions not the average rule. The ‘businesses’ most of the
poor run are simply not profitable enough to transform their lives, MFIs
notwithstanding! Other solutions have to be found.
Why are preventive
health measures which are both cheap and effective neglected and expensive
cures focussed on? What makes the admittedly inadequate state expenditure on
health largely infructuous? What are the consequences of asymmetry of
information amongst the poor, and moral hazard amongst medical practitioners,
for the health of the poor?
The list goes on and on.
The best that the blog
format adopted here can do is to give a brief glimpse of the insightful nature
of this work. The book is long and by no means a light read but the effort to
work through it is enormously rewarding.
Happy reading!
