crisis, shows up among the
most vulnerable.
○ Climate Calamity
Inward-looking leaders are
poorly equipped to con-
front another systemic risk:
climate change. The conse-
quence of temperatures 1C
above preindustrial levels
is already evident. Extreme
weather events—whether
historic floods in Thailand
or Category 5 hurricanes
battering the U.S.—are wreak-
ing havoc on housing, infra-
structure, and supply chains.
Insurance losses have risen
fivefold since the 1980s.
As temperatures continue
to move higher, the economic
impacts will be wide-ranging.
Uncertainty about climate
risks creates a disincentive for
businesses to invest. Higher
temperatures reduce labor
productivity. Climate adap-
tion diverts resources away
from more productive uses.
The transition to a low- carbon
economy brings opportuni-
ties, but a trade-off between
emissions and growth may
be unavoidable. Putting a
dollar value on the economic
impact is tough. The United
Nations Intergovernmental
Panel on Climate Change esti-
mates the cost is from 0.2% to
2% of global GDP a year. Even
at the lower end of that range,
the costs will be measured in
hundreds of billions of dollars
a year. At the upper end,
they’re in the trillions.
To measure the risk from
climate change, we use the
Notre Dame Global Adaptation
Initiative vulnerability index
from the University of Notre
Dame in Indiana. In the index,
low- and middle-income
countries, with high tempera-
tures, reliance on agriculture,
vulnerable populations, and
limited resources for adapting,
are the most exposed. Among
major economies, India and
Vietnam show up among the
most vulnerable.
○ Driving Development
Even as disruptive forces
loom, low- and middle-income
countries face a challenge in
putting the traditional drivers
of growth into place. We track
traditional drivers of develop-
ment across four pillars:
� Increases in the labor force
provide a basis for growth. We
employ projections of the rise
in the working-age population
through 2030.
� Expansion in the capi-
tal stock, efficiently allocated,
raises labor productivity. We
use measures of investment as
a share of GDP and as proxies
for the quality of that invest-
ment, gross government debt
as a share of GDP, and a mea-
sure of investment freedom
from the Heritage Foundation.
� Policies that increase
productivity unleash the
economy’s potential. We
incorporate a set of mea-
sures to capture education,
