The document summarizes an economics revision workshop covering international trade and exchange rates. It includes an activity where students predict the finishing positions of different countries' snails in a race. The workshop then covers topics like the changing patterns of global trade, current accounts and balance of payments, theories of free trade and protectionism, and analysis of exchange rate systems. Interactive exercises analyze trade flows and drivers of change, current account deficits, theories of comparative advantage, types of protectionist measures, and exchange rate movements.

Settle down quickly and get ready to play
The Great Economics Snail Race

3. Meet Winston. He’s representing the UK in ‘The Great Economics Snail Race’!
He is going to compete against snails from other countries over 4 different heats.
Your task is to decide which position you think that Winston will finish (out of 5)
and which snail will win in each race.
Get ready to start!

12. A Level Economics – Year 2 (A2) Revision Workshop
The changing pattern of global trade
26
• China’s growth in exports (due to WTO membership &
relaxing of trade barriers)
• Improvements in global transport and
communications links
• Increase in scale/scope of global production chains
• Credit Crunch still affecting access to trade credit
• Some countries increased barriers to trade following
recession to protect their economies
• 50% • 25%
• 16%• 6%

Drivers of change in the global trade pattern
27
• Slowdown in China, not matched by boom elsewhere (yet!)
• Increased “protectionist mood” – anti-immigrant policies, “buy local” programmes, new
“Cold War”
• Gains from improved transport and communications tech already heavily exploited
• “Death of Distance”
• Process of increased interconnectedness across the globe; increasingly integrated
markets, cultures, policies, economies and industries
• International organisations – WTO, IMF, World Bank, NATO, UN
• Agreements on freer movement of goods, services, capital and labour
• Technology (e.g. communication & transport) allowing global production / rise of MNCs /
global media / containerisation / global financial system
• Increasing role of governments rather than free markets following the financial crisis
• Trade blocs promote trade diversion away from the rest of the world
• Reduced free movement of labour – tighter visa regs, border checks etc (terrorist threat)

17. A Level Economics – Year 2 (A2) Revision Workshop
Why is a current account deficit harmful?
28
• Deficit a sign of undesirable / uncompetitive exports – leads to
reduction in AD, increase in structural unemployment which is expensive
to tackle
• Example: possibly the US with its strong $ and inefficient production
facilities
Structural issues
(unemployment and
growth)
• Dependent on importing food and essential items, which can be
problematic politically and cause imported inflation; indicates lack of
diversity
• Example: Ethiopia remains dependent on food imports
Over-reliance on other
countries
• The BOP must balance, so a deficit on the current account could be
financed by hot money / currency on the financial account – hot money
is “footloose” and can cause a currency crisis
• Example: many South American countries are struggling following the
US interest rate increase
Financed by hot money

18. A Level Economics – Year 2 (A2) Revision Workshop
Why is a current account deficit not harmful?
28
• During times of economic boom, incomes rise and with a high MPM,
demand for imports will rise (luxuries, choice etc)
• Example: deficits caused by imports of oil, whose price fluctuates
alongside the economic cycle
May be cyclical
• This is the case for many LEDCs – such imports increase LRAS and allow
non-inflationary economic growth, which can lead to development
• Example: South Korea’s Import Substitution Industrialisation policy
encouraged imports of tech and capital, but not imports of consumer
goods and services
May be importing
technology and capital
• Because the BoP must balance, there could be an inflow of FDI on the
financial account – this increases capital, and therefore AS, leading to LR
growth, and a chance to build an export market
• Example: UK manufacturing and hi-tech industry
Accompanied by
strong inwards FDI

Producing for a larger worldwide
market means that businesses
can benefit from economies of
scale
Competition forces prices down
due to increased number of
suppliers, and lower production
costs
Greater variety of goods and
services, different cultures and
their products
Greater specialisation according
to comparative advantage
allows output to increase from
the same inputs
Countries that trade with each
other rarely go to war –
improves international relations
and global confidence
Trade is not just in consumer
goods but in capital goods. Also
MNCs and global production
encourages diffusion.

Why do countries use protectionist measures?
29
Infant industry and sunset industry argument
• New industries need time to benefit from economies of scale and become competitive enough to survive international
competition; in old industries, workers need time to retrain
Improve economic diversity
• Economies don’t want to suffer from a “resource curse” or struggle with over-reliance on one industry
Protect jobs and encourage growth
• Import Substitution strategies can increase AD, and since demand for labour is a derived demand, jobs are protected
Strategic industries argument
• These could include food, weapons, energy, water etc

28. A Level Economics – Year 2 (A2) Revision Workshop
29Protectionist measures can protect jobs, especially for low-paid or low-skilled
workers who would otherwise struggle to find work
Low-skilled workers are often occupationally and geographically immobile,
and may work in industries which are increasingly suffering from competition
from low-cost producers overseas
Thousands of jobs in the UK were lost in 2015 from the closure of Tata’s and SSI’s steel-
plants in places such as Scunthorpe and Glasgow due to Chinese competition. Many
workers and MPs believe that subsidies would have helped prevent the crisis.
However, overseas manufacturers are more competitive and efficient, so it is better for
the UK economy if cheap steel is imported – it keeps down cost-push inflationary
pressures, and can stimulate steel-using UK industries, such as car manufacturing.
Furthermore, steel subsidies to protect against overseas competition would be
expensive and difficult to justify in the current economic climate of continued austerity.
The money could be better spent providing retraining for displaced workers.
The benefits of protectionist measures, such as subsidies, in order to protect jobs, will only
be felt in the short-term; in the long term they are likely to prove too costly. The gov’t
should instead help with retraining and improving occupational mobility of steel workers.
