Comments on O’Rourke
Andrew K. Rose
UC Berkeley, NBER, CEPR and EIEF
Some Tensions Exist:
Let’s Eat the Cake and Have it Too
• Is Loose Monetary Policy
– “better policy response”
or
– “beggar thy neighbour”?
• Special Role of American Dollar
– “days of dollar supremacy numbered”
or is there
– “no alternative”?
1. O’Rourke data on Industrial
Production Now and Then: Terrifying!

Dating the Recessions
• O’Rourke uses June 1929, April 2008
• But NBER has peaks at August 1929 (2 months
later) and December 2007 (4 months earlier)
– CEPR uses January 2008 (3 months earlier)
• Does Changing Dates by 6 months Matter?
– Quick Check on American Data shows …
Using NBER Dates: Scary but …

2. Is Decline in Industrial Production
Serious, Permanent?
• Many Countries
– Serious decline in (trade and) IP
– Dramatic bounce-back of late in at least some
• Especially Small Open Economies Most Affected by
Trade

Relevant?
Industrial Production and GDP
• Industrial Production a Small Part of GDP
– OECD: Most value-added and employment is
services
– USA 2009Q1: GDP = $14,097.2 billion
– Equivalent IP ≈ $5035.7 billion (35%!)
• Unusually cyclic compared to services, direct
government (especially investment,
inventories, durable goods)
• But IP is still obviously relevant …
And IP Shows Up in GDP:

3. Why Has Trade Collapsed?
• Fall in International Trade has been:
1. Very Fast
2. Very Large
3. Essentially Simultaneous across Countries
•
•
10/’08 – 3/’09 OECD average was -21%!
“Great Synchronization” of Trade Collapse
“Great Synchronization”
High fraction of countries now experiencing
negative export value growth
But: No Big Signs of Protectionism
• So the decline in trade simply cannot have
been “unnatural” – must be some “natural”
reason(s)!
Policy Implication
• Fears about Protectionism are forward-looking
– Warranted and Reasonable, but
– Not (yet) Realized
– Reasonable if protection driven by macroeconomy
Causes of Collapse of Trade
• Trade always responds disproportionately to
recessions (goods respond more than services)
– Contracts faster than GDP, bounces back faster too
• Shrinking Trade Credit may play special role in ‘08
• Probably Key: More Trade in Intermediates
– Trade recorded gross, not value-added; trade may fall
a lot without value-added changing much
– Elasticity of Trade wrt Income rising; now ≈ 4 (Freund)
• So 5% decline in global growth → 20% decline in trade
• Elasticity used to be <2 (Irwin)
Should We Care?
Minnesota on Great Depression
• Cole and Ohanian agree with O’Rourke: trade
effect on GD is trivial
– (So is everything else … though any policy
response slowed recovery … of course …)
– Still, perhaps trade (and protection) a side-show …
except insofar as it affects real activity …
4. Great Depression: a Once-Off?
• One observation can estimate one coefficient
with zero degrees of freedom
• World Quite Different Now
– Legacy of WWI; Gold Standard; Communism; Fascism;
Empires; Stabilizers (automatic, discretionary) …
• More Trade Institutions (in part, because of GD)
– WTO
– Regional Trade Arrangements
– Recognized Importance of Trade (e.g., G-20)
• Previous Recessions Haven’t Lead to Protection
– 1975, 1982 recessions; Asian crisis; …

No “Golden Fetters” preclude growth

Vox-Ops
• Must Guard Against Exaggeration
– Necessary for Policy-Makers
• Reform is Difficult
– But Care Required for Academic Audiences
• Vox has a LONG memory
