Introduction
• confused Level 5 Economics
– 3 types of economics with different assumptions
all blended into standard introductory courses
a) full-employment neoclassical win-win economics
b) unemployment/recession lose-lose economics
c) mercantilist zero-sum win-lose (lose-win) economics
• we need to be more clear when we shift
assumptions away from (a)
– (b) is discussed in recent context by
•
Paul Krugman (2008,2012), Richard Koo (2009,2011)
– (c) relates to international economics
•
especially when we move away from balanced trade
Mercantilism
• represents business and political practice in
the early (pre-industrial) period of global
capitalism
– 15th to 18th centuries
• reflected in economic thought of the time
– doctrine that nations should aim to achieve a
trade surplus (seen as a 'win') every year
• and should practice deficit-avoidance strategies
– supremacy of production over consumption
• mercantilist strategies in the 1920s
– contributed significantly to the Great Depression
Figure 1: Analysis from Google NGRAM
Teaching International Trade at Level 5
• we start appropriately with balanced trade
and the resulting win-win 'gains from trade'
– imports are clearly presented as benefits, and
exports (what are given up) as costs
– we don't but could address unbalanced trade as
'inter-temporal trade' (Corden)
• this allows students to understand inter-country debt
• debt servicing clearly understood as a net flow of goods
and/or services from debtor to creditor countries
– instead we refer to 'surplus' countries as if that
has the same meaning as 'creditor' countries
• we drift into the 'exports-good imports-bad' idea

Eurozone Crisis: Systemic Approach to Teaching
• exemplar case-study of unbalanced trade
– systemic unbalanced trade zone within a global
economy with chronic fiscal imbalances and with
a perverse floating exchange rate system
• fixed system of exchange rates collapsed
– 1910s, 1930s, 1970s
– Eurozone an extreme form of fixed exchange rates
in which even devaluation is not an option
• northern Eurozone (eg 'BANG') countries
– persistent trade surpluses; undervalued currency
• reverse applies to southern Eurozone 'PIIGS'
Current Account Rebalancing Solutions
• northern and southern Euros ?
– need to imagine creditor countries running
deficits, and debtor countries running surpluses
• is it a matter of northern winners and southern losers?
• austerity ?
– reminiscent of failed 1920s' strategies to achieve
rebalancing deflation in trade-debtor countries
– failed then, in part because creditor countries
would not play their part
• 'deficit' countries could not import more (had to import
less) and 'surplus' countries would not import more
• 'surplus' countries need inflation to balance the
deflation imposed on the debtor countries
Precedent: Australasia in the 19th century
• seven countries with a single currency (£)
– region net debtor; ongoing finance restricted 1890s
– problems of unbalanced trade
• short term resolution through labour market mobility
• doesn't resolve government component of external debt
– longer term solution --- political union
•

•
•
formation of Commonwealth of Australia in 1901
New Zealand chose not to participate
reduced problem from extra-national to inter-provincial
federal government activity smoothed imbalances
• Eurozone
– compare and contrast East Germany with Greece
– futile to seek huge wage disparities in EU
Conclusion
• economics should be taught with consistent
assumptions about costs and benefits
– mercantilist assumptions should be rejected
• chronic trade imbalances in the real-world
present great opportunities to teach
– debt as inter-temporal trade
• the requirement for completion of such trade contracts
– contrasting exchange rate mechanisms
• means to correct trade imbalances
• real-world failures of these mechanisms
– the consequences of unresolved imbalances
• use-it or lose-it principle: spend your credits or lose them
