Why do high & volatile prices matter?
SLIDE 4
Food price volatility
Shocks to output are a major source both of
income instability to farmers and of price volatility
Shocks to demand from—for instance—
biofuels, may also contribute
Globalization helps reduce price volatility by
diversifying sources of supply
SLIDE 5 Impacts depend on stock levels
If stocks are normal, adverse shocks can be
absorbed by stock reduction
Key problems arise when stocks are low
- Reducing demand in line with supply requires large
increases in price
Prices spend long periods in the doldrums
punctuated by short but intense price spikes

Impacts of food prices on the poor
Poorest spend 75% of income on staple foods 3/4 of poor people are rural & earn most of
their income from farming
- Poor farmers don‟t gain much from higher prices
Many are net buyers of staple foods
- Little opportunity to increase output in response
to higher prices
Net impacts on poverty?
- Are the gains to poor net sellers outweighed by
the losses to poor net buyers?

2010-11 price surge
Especially June to December 2011
- Wheat, maize, many other commodities
But fortunately not rice
Used detailed data on the extent of pass- through into domestic prices
Data on 28 countries & 38 commodities
Estimate that 44 million have been pushed below the $1.25/day poverty line
- 68 million entering poverty; 24m escaping

Trade policy options for poor countries
SLIDE 12 What should poor countries do?
An attractive policy option is to:
- Restrict exports when world prices are high
Lower tariffs or pay import subsidies if an importer
Gouel & Jean show this can be welfare-
improving for a small open economy
- Where food budget shares are high & policy
makers are risk averse
- Where these conditions are not met, volatility is
theoretically preferable
- Trade policy alone dominated by a combination of
trade & storage policies
SLIDE 13 In practice
Many countries are strongly countercyclical
with their trade policies
- May also raise protection and/or pay export
subsidies when prices slump
Historically both industrial & developing
countries have insulated in this way
- Although major exporters have learned that this
reduces their perceived reliability as suppliers and encourages importers to protect
- Only WTO rules stopped rich countries using
Variable Import Levies to export instability

SLIDE 15 Some simple principles
Import tariff reductions more frequent than
export restrictions
- A mirror image so why criticize export restrictions
more than import tariff reductions?
Export bans frequently used but export taxes
almost always preferable
- Optimal price insulation likely to be partial
- Zero exports most unlikely to be optimal
- Export bans likely generate domestic price volatility
- Prospect of periods of very low domestic prices
likely to reduce supply
SLIDE 16
The collective action problem
SLIDE 17 A collective action problem
If everyone attempts to reduce the impact of
world price increases
The policy appears to be a success
- “Domestic prices rose less than world prices
when prices surged”
But it may be collectively completely
ineffective
- The world price increases one for one with
attempts to lower domestic prices

SLIDE 20 Like the grandstand problem
When everyone in a crowd stands up to get
a better view
But unilateral refusal to participate isn‟t a
solution
- If I don‟t stand up, I get a terrible view!
Unfortunately, insulation against staple food
price changes can have more serious consequences
- Magnifies the volatility of international income
transfers
SLIDE 21 Use World Bank data on distortions to
agricultural incentives
- Data for 75 countries
- Update to 2008
Assess the impacts of rising export barriers,
declining import barriers, on world prices
Analyze price rises of 1973-4 & 2005-8

SLIDE 26 Insulation policies
Clearly, insulation policies are much less
effective than they appear to individual countries
- Redistribute, rather than reduce, domestic price
volatility
For large countries, such as China, India and
Vietnam, the effect is very direct
- Export restrictions raise world prices, reducing the
effectiveness of the policy
For all countries, the collective action problem
remains
SLIDE 27
International policy options
SLIDE 28 Current WTO policies
WTO bindings limit import tariffs
- Lower bindings mean less scope for tariff reductions
- Variable import levies banned in Uruguay Round
- Special Safeguards directly structured to insulate
domestic prices
Export disciplines are very weak
- Export taxes not disciplined at all
- GATT Article XI bans export quantitative restrictions
Except in cases of food shortage
SLIDE 29 Questions for international policy
How might cooperative policies improve on the
current beggar-thy-neighbor regime?
More information on stocks and policies Would restrictions on export barriers help
increase the confidence of importers?
- Should food aid be exempted from export bans
Should policies focus just on export barriers?
- Or include import barrier reductions?
How might international disciplines on trade and
storage policies work?
- Convert export restrictions to taxes?
- Aim to reduce the degree of insulation?
SLIDE 30 Conclusions
Prices of staple foods prone to intense but
short-lived price spikes
- Extremely costly for the poorest
Optimal policy for an individual country likely
to involve beggar-thy-neighbor policies like export restrictions & import subsidies
But these policies collectively self-defeating A key challenge is designing new policy rules
to deal with the collective-action problem
