Balance of Payments Adjustment Policies
Policies to correct a BoP imbalance
• Most discussions focus on countries
running a current account deficit
• But persistent surpluses can also be a
problem!
• Both deficit and surplus can be
described as a disequilibrium
• Evaluation might consider:

Automatic partial correction of a deficit
Demand-side policies
Supply-side policies
The consequences of policies for other
macroeconomic objectives such as growth,
inflation and jobs

Why might the deficit
as a share of GDP
be a better guide to
the size of a trade
imbalance?
Are deficits self-correcting?
• Some partial self-correction
• Economic slowdown and recession
– Squeeze on real incomes and output
– Fall in import demand
– Releases capacity for exporting
• Deficit might lead to depreciation in the
exchange rate
– Change in relative prices of exports and
imports
– Expenditure-switching towards exports and
away from imports
– Depends on price elasticity of demand for X
and M and also elasticity of supply

But what are the wider
economic effects?
Expenditure switching
• Expenditure switching:
– Change in relative prices of X and M
– Changes incentives for consumers
– Changes profitability of exporting
– Can be caused by
• Movement in the exchange rate
• Introduction of import tariffs and other forms
of protectionism
• Period of high or low relative inflation
– Key point is whether trade volumes respond
to changing prices
– I.e. price elasticity of demand for X and M

The J Curve
• Effect of a depreciation on the trade deficit
depends on price elasticity of demand.
• In the short term, demand is often inelastic –
limits extra revenue from exports
• Demand for M is inelastic – higher prices cause
a rise in total spending on imports
• The J Curve effect says a trade deficit can
worsen after a depreciation, but get better in the
long term provided that the elasticity of demand
is high enough
• Marshall-Lerner condition: Trade balance will
improve if Ped X + Ped M . 1
• Elasticity of supply of domestic producers is
also important (often forgotten)
The J Curve effect

Ped X + Ped M > 1 for

Expenditure Reduction
• Expenditure reduction
– Cutting aggregate demand
– Direct effect on consumption and therefore
demand for imports:
– Possible routes:
• Higher direct taxes – lower disposable
income
• Low taxes on saving
• Increased interest rates – to dampen
consumption
• Cut in government spending
– Focus here is on income elasticity of
demand for imports
Supply-side policies
• To rebalance trade over the medium term
• Focus on
– Improving competitiveness in global markets:
• Innovation
• Research and development
• Product quality / design
• Infrastructure to support trade sectors
– Attracting inward investment – producing output
domestically and then exporting
– Raising productivity / lowering unit costs
– Developing areas of new competitive advantage
– Raising foreign income elasticity of demand for
exports
– Reducing foreign price elasticity of demand for
exports
Weaknesses on supply-side and UK trade
• Persistent productivity gap
• Low business investment as a share of
GDP
• Low levels of research and
development
• Loss of capacity in manufacturing
industry
• Evidence that UK exports have lower
income elasticity of demand than our
income elasticity of demand for imports

Summary points
• Some trade deficits are partially self
correcting
• But recession and a depreciation are
not enough if the root causes lie on the
supply-side of the economy
• Ultimately BoP adjustment requires:
– Period of below trend growth
– Improvement in investment in traded goods
industries
– Control of price and cost inflation relative to
that of our competitors
– Open trade to drive better export
performance
– Protectionism is not the answer
