Bad News for Chinese Growth!
• GDP growth rates, savings rate, and current
account/GDP peaked around 2011
• Life-cycle theory links the working age cohort
pattern to these variables
10
Something More Sexy
• The sex ratio pattern plays an important but mostly
unrecognized role
• Key researcher: Shang-Jin Wei (Berkeley student,
now on leave from Columbia GSB at ADB)

• The competitive saving motive: people save partly due to
a desire to improve their status in the dating/marriage
market
• Can hold in any society
• But a rise in the sex ratio both greatly exacerbates its relative
importance as a determinant of the savings rate and make it
possible to estimate it empirically
• The effect can go through the parent cohort
• Finding: about ½ of the rise in the household savings
from 1990-2009 may be linked to a rise in the sex ratio
13
Many Implications!
• Higher savings and thus higher current account
surplus results from a rise in the sex ratio
• Relationship between competition on human capital vs
physical capital accumulation
• Can also have major effects on housing prices
• Important for other countries (India …)

Impact on Economic Growth
• Much evidence that sex imbalances adversely affect
crime
• But some potential benefits
• Entrepreneurship induced by sex imbalance
• New domestic private firms – important growth engine –
more likely to emerge in regions with sex imbalances
• Parents with sons more likely to be entrepreneurs with local
sex imbalances
• More dangerous/unpleasant work (e.g., mining) by
households with sons in regions with sex imbalances
• No effect on labor supply of households with daughters
• Regional GDP grows faster in provinces with higher sex
imbalances
• Net Result: possibly extra 2 ppts/year (!)
Effects of Recent Changes in Population Policy
• From “one-child policy” to “two-child policy”
• Elasticity of child-bearing parents
• The short run response is mild: about 20%
• Medium term: could rise to 40-60%
• On working cohort:
• No effect in the next 15 years; then improving
• On dependence ratio
• Worsening in the next 15-20 years; then improving
• On the sex ratio for the pre-marital cohort
• Improving
Effects, continued
• On household savings and current account
• Decline/improving
• Will see discussion on the “success of the rebalancing
policies of the government” even though it could be an
unintended consequence of the changes in the population
control policy
• On GDP growth
• The sex ratio effect: further moderation of the growth rate
• The working age cohort effect:
• No effect to small further moderation in the next 15 years
• Improvement after 15 years

• What exactly do we mean by a PRC slowdown?
• Soft vs. hard landing scenarios
• How big is the impact on different regions and
countries?
• Two approaches:
• “Standard analysis” - Global Projection Model
simulations,
• Taking into account GVCs - using inter-country I-O tables
Soft vs. Hard landing scenarios
• “Soft landing” scenario
• A reduction in GDP growth by 25 basis points /year
• Corresponding deceleration in investment
• Current baseline - we’ve seen it in the last two years
• Relatively “orderly”
• “Hard landing scenario”
• Sharper and more persistent growth deceleration
• ~2pp per year for two years)
• Accompanied by a spike in global risk aversion
• About one-third of a “Lehman” in VIX
Guestimates from Global Projection Model
• 7 regions (US, Euro area, Japan, China, Emerging Asia
ex-China, Latin America, and Remaining Countries); 85%
of world GDP
• (Aims to strike a balance between DSGE and VAR/time
series models)
• Developed mostly at the IMF
• Can identify shocks, (some) transmission channels,
policy responses; gives comprehensive picture, as it
contains trade, financial, and commodity price channels
• Caveats: (a) no GVCs, and (b) few individual countries
“Soft Landing”
Substantial effects on Japan and Emerging Asia,
little effect on US and Europe…

China Impact: Taking into Account
Regional and Global Value Chains
Assessing spillovers via world
input-output tables
• Can trace effects on individual countries/sectors
• Explicitly accounts for trade and production linkages
• Need to specify how much various domestic
demand components slow in China
• Limitations: uses production linkages as of 2011;
static model (no adjustment of production in
response to the shock); no price/ToT effects; no
policy response
Most of China’s recent slowdown has come
from a slowing of investment…

• When we consider input-output linkages or GVC
linkages, it becomes important to distinguish shortrun and medium-run effects
• In the short-run, because the production relations
are hard to adjust, the negative effects tend to be
big – perhaps comparable to the hard landing
scenario in the GPM simulations
• In the medium-term, however, production relations
can adjust, and only the location of the final
demand would matter. This often implies a smaller
negative effect from a fall in the growth rate of
China’s final demand
Even if China’s GDP were to fall by 4.5pp, the
effects for other countries tend to be more
muted in most cases

China Slowdown: Keeping Things in Perspective
• “Soft Landing” still much more likely than “hard
landing”
• China will remain a main engine of growth for the
world economy in the foreseeable future
• Slowdown inevitable: Pritchett and Summers
emphasize how unusual durability of Chinese growth;
underemployed labor now gone, there are diminishing
returns to capital, hard to boost service productivity,
SOEs need reform, heavy debt …
• With the changes in the population control/family
planning policies, and with continued growth in per
capital income, its effect after twenty years will only
rise
