- The nexus between the growth of GDP
- and development
3Growth and development 3 views
- Development gt growth (GDP) also individual,
social, environmental, institutional indexes - Different views of the relation growth ?
development - A) ? growth ? ? development unjustified
assimilation -
- the means becomes an end in itself ? main goal
of economic policy - ? growth ?gt ? development must be also
sustainable -
- main goal of economic policy sustainable
development - C) ? growth ? ? development theory of
downscaling (Latouche) -
-
4A) assimilation of development to growth
- Based on the following arguments
- Per capita GDP reliable indicator of individual
well-being - ? well-being (utility)
- ? growth ? ? development
- ? health
- Growth GDP necessary condition to conquer poverty
- Kuznets curve growth increases inequality after
the industrial take-off but then reduces it - Environmental Kuznets curve growth deteriorates
the environment after the industrial take-off but
then improves its quality

11The first happiness paradox 1
- 1st paradox ?p.c. Y does not ? ?happiness
- We know since long that the GDP index is a
strongly distorted and misleading index of
well-being - - exhaustion of natural resources
- Not registered - deterioration of natural
and social capital - - social and environmental negative
externalities - - relational goods
- Unduly registered - defensive expenditures (e.g.
conditioning)
12The first happiness paradox 2
- Alternative measures to correct the shortcomings
of the GDP - NEW (Net Economic Welfare) suggested by Nordhaus
and Tobin (1973) - grew les than the GP in the post-war period in
industrialized countries - ISEW (Index of Sustainable Economic Welfare) by
Daly and Cobb (1989) -
- while the US GDP grew from 1951 to 1986 at an
average rate of 1.90, - the ISEW grew much less (0.53) and became
negative since early 1970s - ? the alternative indexes focus on the same
neglected factors stressed by the happiness
literature
13The second happiness paradox
- 2nd paradox ?p.c. Y does not ? ? health
- Inadequacy of the general health indexes
-
- The health of individuals depends on life length
but also on its quality - - ? frequency of depression and suicides
- - a long life is not necessarily a happy life
- - well known since long the immortals
(struldbrugs) are unhappy - (Gulliver travels, Swift, 1726)
- Also the general indexes of health should be
corrected by taking into account the quality of
life - ? this would further enhance the decoupling
between growth and health
14The two happiness paradoxes and economic policy
- 1st paradox ?p.c. Y does not ?
?happiness - Twin happiness paradoxes
- 2nd paradox ?p.c. Y does not ? ?
health - Not true paradoxes long list of explanatory
factors - to measure development with GDP
- The real paradox is the obstinacy
- to assume growth as the main policy goal
- neoliberal camp (Bhagwati, 2004)
- Bipartisan consensus reasserted
- Keynesian camp (Benjamin Friedman, 2006)
- Extremely misleading position to be rejected

16KUZNETS CURVE (1955)
- Plausibility ? take-off (triggered by the
adoption of outward-oriented policies) - -diffusion takes time
- -urbanisation
- -growing pressure in favour of redistribution
- (progressive taxation, transfers, welfare
state) - Optimist message the problem tends to disappear
spontaneously - Kuznets conjecture corroborated by econometric
studies up to the 1970s - since the early 1980s new econometric studies
have progressively weakened the empirical support
(emergence of the U-pattern in OECD countries) - historical explanation the KC described a
specific historical process and not general
tendencies intrinsic in the process of
globalisation? policy is needed

19Impact of globalisation on the social conditions
of sustainability 2) poverty
- we have to reject the optimist message of the
Kuznets curve - however, according to many economists, in order
to study the social effects of globalisation we
should focus - not on inequality but on poverty
- Conviction based on the Bhagwati hypothesis
and prescription - Countries have similar distribution of income ?
we can only reduce poverty by increasing the rate
of growth of income - (Bhagwati, 2004, p.66)
20Impact of globalisation on the social conditions
of sustainability 2) poverty
- misleading hypothesis Bourguignon and Morisson
(p.733) calculated that - had the world distribution of income remained
unchanged since 1820, the number of poor people
would be less than 1/4th than it is today and the
number of extremely poor people would be less
than 1/8th of what is today - ? we should try hard to realize a more
egalitarian growth

23Environmental KUZNETS curve (Panayotou, 1993)
- No historical series of comprehensive indexes of
environmental deterioration - ? correlation with specific indexes of
environmental deterioration - Some of them behave as in the KC ? environmental
Kuznets curve - Plausibility
- -take-off shift of labour from agriculture to
heavy industry - then increase of light industry and services
- -growing pressure of final users and electorate
- Econometric studies seemed to corroborate the
hypothesis but then it was falsified in many
cases - - it works only when the environmental effects
are local - - recently N-shaped curves

26Conclusions on A) growth development
- Not always postwar growth translated in ? quality
of life - - the well-being of citizens (measured in terms
of subjective happiness) did not increase in
industrialized countries - - health in terms of quality of life often did
not improve - - poverty in absolute terms increased and in the
near future is likely to grow also in relative
terms - - inequality resumed growth since the late 1970s
- - environmental deterioration grows with limited
exceptions
27Sustainable development definitions
- Development
-
- process of expansion of individual
economic freedom (Sen, 1999) - Sustainable development
- Development is sustainable if it satisfies
present-day needs without compromising the
capacity of future generations to satisfy their
needs (Brundtland Report, 1987) -
28Sustainable development

CHOICE FREEDOM

29Ethical and economic foundations the social
condition
- equal access to the basic economic opportunities
ethical foundations - this is also a fundamental condition of economic
efficiency - -prerequisite for a well-functioning competitive
market guarantees that the winners of the
economic competition are actually the best
participants as each of them plays on a level
playing field - -poverty (malnutrition) implies a restriction of
the option set reducing the potential
contribution of poor people to economic
efficiency and wealth - among poor people who cannot afford a good
education there are potentially good scientists,
engineers, physicians, managers and so on - -social and political tensions that have negative
effects on income growth - (Alesina and Perotti, 1996 Benhabib and
Rustichini, 1996)
30Ethical and economic foundations the
environmental condition
- similarly environmental degradation has adverse
economic effects - ? health of people ? ? productivity
- ? land productivity
- poverty-environment trap the poor rely heavily
on the direct exploitation of natural resources - ? environmental degradation ?? poverty ??

33C) Point of view of de-growth
- The concept of sustainable development is
considered as an oxymoron (Latouche) - This assertion is based on the misleading
assimilation of development and growth - and thus on the confusion between the two
preceding points of view - -literal de-growth as necessary condition of
sustainability - Two versions
- -provocation to change paradigm
- - development depends on the quality of
(de-)growth, not on the sign - Critique
- - focus on the quantitative features
- De-growth does not help within the current model
of development (recession) - we have to focus on the qualitative features of
growth - this is what the conditions of sustainability of
development invite us to do
34Models of development
two phases
WITHIN-COUNTRY INEQUALITY ENVIRONMENTAL DETERIORATION
1945-1971 MODERATE IMPROVEMENT WORSENING
1980-2010 WORSENING PARTIAL IMPROVEMENT
NEITHER OF THE PHASES OF POSTWAR DEVELOPMENT MAY
BE CONSIDERED AS FULLY SUSTAINABLE ALTHOUGH FOR
DIFFERENT REASONS
35Sustainable development and the crisis
- The crisis undermines the transition to
sustainable development - ? short-termism
- ? oil price ? ? investment in renewable energy
sources - ? variability oil price ? ? investment in
renewable energy sources -
- ? trend oil price ? obstacle to recovery
- ? attention on the environmental quality when it
involves higher costs - ? concern for ethics if it involves a monetary
cost - We should try hard to avoid all these destructive
effects - it is during a crisis that the seeds of future
development are planted -
36Unep report A Global Green New Deal
- stimulate the recovery
- GGND
- strengthen the sustainability of the world
economy - Governments invited to invest 1/3 of 2500 Mld
anti-crisis - environmental (energy-climate, water,
ecosystems) - in sustainability
- social (inequality and poverty)
- A study of HSBC shows that some countries move
in this direction - South Korea 81, China 38,
- but
- France 21, Germany 13, USA 12, UK 7, Spain
6 - Italy is last in this list 1,3
-
37The future development cycle
-
- Each development cycle is pulled by a strategic
sector - -railways 1840?
- -electrification 1900?
- -auto, domestic appliances 1950?
- the new cycle is incubated during the great
crises - e.g. SME made in Italy (1970?)
- -renewable energy sources
- The next cycle ecologic conversion -social
and environmental consumption - -SRI
- It is important to catch the bus on time
- e.g. automotive industry in the US spoiled by
the law price of gasoline and lax environmental
constraints -
