Lecture Goals
• Supply & demand model
• Winners & losers from protectionist policies
• Review and extension of factor & sector
models, including the role of institutions
Supply and Demand Model
Demand curve
• Three students
– 1 loves coffee, would pay $5 (or less) per cup
– 1 likes coffee, would pay $3 (or less) per cup
– 1 only drinks coffee if it’s cheap, would pay $1 (or less)
per cup
• Draw a demand curve
– How many cups would sell at $1? At $3? At $5?
– Put price on the vertical axis
– Put quantity on the horizontal axis

Supply Curve
• Three baristas
– 1 loves to make coffee, will make cup for $1 (or more)
– 1 likes to make coffee, will make cup for $3 (or more)
– 1 dislikes making coffee, will make for $5 (or more)
• Draw a supply curve
– How many cups will be made if price is $1? $3? $5?
– Price on vertical axis, quantity on horizontal axis

Equilibrium
• Assume all cups of coffee must be sold at the
same price
• How many cups of coffee will be bought and
sold, if everyone makes a decision they won’t
regret? Why?
• At what price will the coffee be sold? Why?
(if you know the answer, please ask your
neighbors if they need help)

Important for this week’s problem set:
• Note that 3 different baristas are selling coffee
• If all cups of coffee are equivalent, they are
analyzed using one supply curve & one
demand curve => all coffee has one price
• If the coffees are not substitutes, then each
needs its own supply & demand curves =>
each coffee has its own price
If there is no trade, Home market price and quantity is
determined by home supply and demand

Trade enables lower prices and more quantity for consumers,
but lower prices (and market share) for comparative
disadvantage producers

Trade protection (e.g., tariffs) increase prices and reduces
quantity for consumers (& producers who use the tariffed good),
but higher prices for comparative disadvantage producers

Society-based models:
Production-induced preferences & coalitions
(Mobile) Factor Model
• Factors mobile (in short run)
across industries
• Abundant factor benefits
from trade (higher returns)
• Scarce factor benefits from
protection (higher returns)
• Coalitions: Abundant factors
vs. scarce factors
Society-based models:
Production-induced preferences & coalitions
(Mobile) Factor Model
• Factors mobile (in short run)
across industries
• Abundant factor benefits
from trade (higher returns)
• Scarce factor benefits from
protection (higher returns)
• Coalitions: Abundant factors
vs. scarce factors
Sector/Specific Factors Model
• Factors immobile (in short
run) across industries
• Factors employed in abundant
factor-intensive industries
benefit from trade
• Factors employed in scarce
factor-intensive industries
benefit from protection
• Coalitions: Export-oriented vs.
import-competing industries
Organizing Interests:
The Collective Action Problem and
Trade Policy Demands
18
Collective action and trade protection:
Producers lobby governments more than consumers
• Consumers
– Benefit from trade (lower prices)
– Are diffused
– Marginal benefit of lower price for each good is small
• Producers of tradeables
– Benefit from
• Protection in own country (higher prices)
• No protection in foreign country (access to markets)
– Are concentrated
– Marginal benefit of protection/access is large
19
Political Institutions & Trade Policy
• Majoritarian vs. PR electoral system
– Majoritarian increases voice of minority interests,
e.g. sector-based interests (based on geography)
– PR increases voice of larger groups, e.g., class or
factor interests, or consumers
20
Example of tariffs, WTO, & distribution
of benefits
• “We had a tire case in which they were flooding
us with cheap … Chinese tires. And we put a stop
to it and as a consequence saved jobs throughout
America. I have to say that Governor Romney
criticized me for being too tough in that tire case;
said this wouldn’t be good for American workers
and that it would be protectionist. But I tell you,
those workers don’t feel that way. They feel as if
they had finally an administration who was going
to take this issue seriously.” – Barack Obama,
October 22, 2012
21
Coalition for tire protection
(from podcast)
• Tire company union
• Tire company owners
• Does this comply with the factor or sector
model?
• Does this imply factors are mobile or
immobile?
22
• “It’s not like you were going to take a 52-yearold guy and send him to internet school.”
(Podcast)
23
China responds to US anti-dumping tire tariff
with anti-dumping chicken part tariff
(US wins on tires, chicken parts still in dispute)
24
Tire tariffs saved/created ~1200 jobs in
Ohio, etc. (swing states)
(Hufbauer & Lowry 2012)
25
Estimated cost to consumers in higher tire prices
estimated at $1.1 billion, or $900,000 per job
26
Another tariff case
(LaFaive 2002, Tran 2003)
• President Bush raised tariffs on steel in 2002
• Winners: Estimated 4,400 – 8,900 steel-sector
jobs in MI & PA (swing states)
• Losers: Estimated decrease in national income
$0.5-1.5 billion; lost jobs in steel-using industries
• WTO ruled against US, authorized EU to retaliate
with tariffs against FL oranges & Harley-Davidsons
(WI, PA, etc.)
• Bush reduced steel tariffs in 2003
27
28
Take-aways
• While trade has many obvious benefits,
protectionism is a common strategy for many
reasons
– Collective action challenges (more voice for
producers than consumers)
– Winners vs. losers among producers (factors or
sectors)
– Some countries may benefit in the long run from
targeted protection policies (Lecture 8)
29
The role of veto players
• Veto player must agree for policy to change
• More veto players => more policy stability
• Institutional veto points
– President, lower house (HR), upper house (Senate)
• Partisan veto players
– Parties in institutional veto points
– Parties in coalition governments

Consumption-induced preferences in
Ricardo-Viner
• “Real” income = Nominal income (wage,
profit, rent) ÷ Cost of consumption
• Trade reduces prices of scarce factor-intensive
goods (imports cheaper than domestic) but
not abundant-factor intensive goods
• If labor is mobile, net gain/loss depends on
wage effect and consumption effect
“Ratio of efficiency to redistribution
gains” (Rodrik pp. 57-58)
• Effects of trade:
– Increased efficiency for national economy
• Move to comparative advantage => gains at national
level
– Redistribution of income
• Comparative advantage factors/sectors win
• Disadvantage factors/sectors lose
• In US: capital owners & high tech innovators win, lowskilled workers (and their employers) lose
• In China: low-skilled workers (and their employers) win
35
“Ratio of efficiency to redistribution
gains” (Rodrik pp. 57-58)
• In China, pre-market reforms, very large
efficiency gains from trade
– (Almost) everyone wins a lot from free trade
• In US, most efficiency gains from free trade have
already been achieved
– Everyone gains a little from more free trade (slightly
lower prices)
– Some gain a lot from free trade (international
investors, high tech innovators, etc.)
– Some may lose a lot (long-term unemployment)
36
“Blue Collar Blues”
• Robert Lawrence (2008):
– Rich have become much richer (capital)
– But blue collar has not become much poorer
relative to middle class (low vs. high skilled labor)
since trade with China. Why? Per Lawrence:
1. Many low-skill intensive goods no longer
produced in US (now imported)
2. US production processes are less labor intensive
than China’s
Data challenges
• Economist article:
– Limited fine-grained wage data make conclusions
difficult
• Elsby, Hobijn, Sahin (2013):
– Self-employed are often excluded from wage
statistics
– When self-employed are included (at market wage
rates), labor share of income is higher than
previously thought

be able to compensate losers => Pareto optimal

But if winners from free trade can influence policy more than losers (e.g., lower
collective action costs), winners can achieve free trade benefits without
compensating losers
Consumption-induced preferences in
Ricardo-Viner
• “Real” income = Nominal income (wage,
profit, rent) ÷ Cost of consumption
• Trade reduces prices of scarce factor-intensive
goods (imports cheaper than domestic) but
not abundant-factor intensive goods
• If labor is mobile, net gain/loss depends on
wage effect and consumption effect
What does factor mobility mean in the
Ricardo-Viner model?

What is labor mobility?
What is capital mobility?
Can land be mobile? How?
How does Hiscox measure factor mobility?
Hiscox measures labor mobility with inter-industry wage variation
High differences between industries in the early 1800s and late
1900s indicates high labor specificity (low mobility)
United States
Hiscox measures capital mobility with inter-industry profit variation
High differences between industries in the early 1800s and late 1900s
indicates capital specificity (low mobility)
United States
What are some sources of labor
mobility vs. specificity?
Increased mobility from:
• Deregulation: lifting of legal restrictions on factor
mobility
• Transportation: lowered costs of factor movement and
reduced importance of geography
• Production innovations that reduce dependence on
specialized skills & specialized equipment
Decreased mobility from:
• Production and technology innovations that increased
dependence on specialized knowledge & equipment
• Economies of scale that raise barriers to entry
Factor mobility effects on political
coalitions and policy demands (Hiscox)
Example
• Assume
– US is land-abundant & capital abundant relative to
trade partners
– Factors are industry-specific (not mobile)
– Workers primarily consume domestic goods
• What do we expect regarding
– Workers trade policy preferences?
– Political coalitions (e.g., between labor, farm-owners,
Textile factory owners, auto factory owners?)
Prediction
• Low-skilled labor in labor intensive industries
favor protection from trade
• Import-competing industries also favor
protection:
– Scarce-factor is labor, so import competing
industry is labor-intensive, e.g., textiles
• Predicted coalition: Low-skilled labor & textile
factory owners
Collective action problem
Example 1
• Assume workers
– Are few in number
– Receive large benefit per person from trade policy
– Are not mobile across industries
• How do these affect labor’s ability to act
collectively?
Collective action problem
Example 2
• Assume consumers
– Are many in number
– Receive small benefit per person from trade policy
– Can easily switch from one product to another
• How do these affect consumers’ ability to act
collectively?
Collective action problem
Example 1
• Assume workers
– Are few in number
• Lower costs to organize if per-person transaction costs
• More likely that each individual will have major impact
• Lower likelihood of free-riding
– Receive large benefit per person from trade policy
• More likely that expected benefit > expected cost
– Are not mobile across industries
• Lower likelihood of free-riding – high opportunity costs
to organizing
Collective action problem
Example 2
• Assume consumers
– Are many in number
• High costs to organize if per-person transaction costs
• Less likely that each individual will have major impact
• High likelihood of free-riding
– Receive small benefit per person from trade policy
• Unlikely that expected benefit > expected cost
– Can easily switch from one product to another
• High likelihood of free-riding – consumers will switch to
other products rather than organize
Sugar quota winners: sugar farms & some foreign governments
Sugar quota losers: consumers, producers using sugar inputs,
would-be (foreign) sugar exporters

Is sugar land mobile or immobile
(across industries?)
US sugar policies cost consumers $1.5B per year, transfers $1B to
US sugar growers. Free trade would benefit US consumers, US
candy producers, and (some) trade partners.
Potential free
trade winners
Free trade winners
Free trade losers
What determines political winners in
sugar trade policy conflict?
• Collective action problem
– Mobility of factors (labor, capital more mobile
than land)
– Size of groups (sugar farmers fewer than
consumers, etc.)
– Net gain per actor
• Political institutions…
Political Institutions & Trade Policy
• Franchise (who can vote)
– Those who can vote (e.g., land, capital, labor) can
more easily push policies that favor their interests
• Majoritarian vs. PR electoral system
– Majoritarian increases voice of minority interests,
e.g. sector-based interests (based on geography)
– PR increases voice of larger groups, e.g., class or
factor interests, or consumers
60
US Political System
• How inclusive is the franchise?
– How does this affect sugar policy example?
• Majoritarian or PR electoral system?
– How does this affect sugar policy example?
US Political System
• Inclusiveness of franchise
Mostly inclusive
– How does this affect sugar policy example?
– Doesn’t(?) – consumers have high collective action
costs
• Majoritarian or PR electoral system?
Majoritarian
– How does this affect sugar policy example?
– Farmer & sugar company votes capture legislators
Conclusions
• Trade policy outcomes, including economic
beneficiaries and political coalitions, depend
upon various conditions, including factor
mobility, political institutions, and collective
action costs
• Solving collective action problems (for larger
groups) and majoritarian political institutions
increase the likelihood of policies that benefit
the majority of the population
