A State-Centered Approach to the Politics of Trade

READING ASSIGNMENT: Oatley – Chapter 5

1

Plan

• What does the state want?

– Survival

• Why would the state intervene?

– Infant Industries

2

What does the state want?

• Improve overall welfare

• Increase its relative power

3

What does the state want?

• SURVIVAL!

• Political Institutions shape the incentives of political leaders

• Under democracy, leaders survive by winning votes

• Under dictatorship, leaders survive by satisfying elite constituents: – military, big business, foreign interests

Time in office

• Does *not* improve a democratic leader’s chances in office

• What then helps democratic leaders survive?

• PROVISION OF “PUBLIC GOODS”

• In the United States:– Economic Growth

8

Time in office

• *Does* improve an autocratic leader’s chances in office

• Why?

• PROVISION OF “PRIVATE GOODS”

• Pay off a small, loyal group of supporters– Military elites

– Business elites9

Changing focus toA more specific institution: Legislative Representation

• Proportional?

• Or Malapportioned?

10

Who needs the most gasoline per capita?Urban v Rural

11

Policy outcome?

• We’ve got Interests & Incentives

• Now, to get the policy outcome,…

• We interact interests/incentives with a domestic political institution:

Malapportionment!

12

Malapportionment tends to weigh RURAL preferences more than URBAN

(i.e., Proportional representation tends to weigh URBAN preferences more than RURAL)

Does this have an effect on NATIONAL policy?

13

Test:

• Does malapportionment affect:

–Gasoline prices

14

15

How can the state get what it wants?

• Industrial Policy

• Tariffs

• Subsidies

• Investment

16

Why does the state protect?

• One answer: Infant industries

17

Infant-industry case

• Long-run welfare gains created by a new industry will be greater than the short-run losses of social welfare

• “infant” industries – like children who need the “protection” of their parents until they grow strong

• Comparative advantages are DYNAMIC

18

19

• Both states are better off with trade…BUT• Would you rather live in Brazil with trade?• Or the United States with autarky?

Infant Industry Argument 1:Fixed costs & Economies of scale

• Economies of scale refers to the decreased per-unit-cost as output increases.

• The initial investment of capital is diffused (spread) over an increasing number of units of output

The marginal cost of producing a good or service decreases as production increases

20

Example

• Suppose an industry requires an initial investment (fixed cost) of $1000

• With 100 customers, the Average Fixed Cost is $10

• With 200 customers, the Average Fixed Cost becomes $5

• This results in a lower average total cost

21

• No economies of scale:– If costs increase proportionately to the quantity of all

input factors

• Diseconomies of scale:– If costs increase by a greater amount than the

quantity of all input factors

• Economies of scale:– If costs decrease by a greater amount than the

quantity of all input factors

22

A different way to approach “returns to scale”

• Where all inputs increase by a factor of 2, new values for output should be:

– Twice the previous output = ?

• a constant return to scale

– More than twice the previous output = ?

• an increased return to scale

– Less than twice the previous output = ?

• a decreased return to scale23

Formal notation• Y is output, K is capital, L is labor, F is the production function:

Y=F(K,L)

• Suppose we double our inputs:

2K, 2L

• F(2K,2L) = ???

–How much does Y increase?

• If F(2K,2L) = 2F(K,L) We have _______ returns to scale

–CONSTANT

• F(2K,2L) > 2F(K,L) We have _______ returns to scale

–INCREASING

• If F(2K,2L) < 2F(K,L) We have _______ returns to scale

–DECREASING 24

Slightly more abstract notation

• Y is output, K is capital, L is labor, F is the production function, a is the increase in inputs

• Y=F(K,L)

• If F(aK,aL)=aF(K,L) Constant returns to scale

• If F(aK,aL)>aF(K,L) Increasing returns to scale

• F(aK,aL)<aF(K,L) Decreasing returns to scale

• For fun: Apply this to the “Cobb-Douglas” production function! Yippee!

25

Bringing the two sets of concepts together?

• Y=F(K,L) + start up costs

26

You can have increasing returns to scale if…

Start-up costs are high

And/or if investments in inputs generate disproportionately high increases in outputs

Infant Industry Argument 2:Economies of experience

• Efficient production requires specific skills that can only be acquired through production in the industry

– Experienced management

– Skilled workers

– Network of suppliers

27

Why can’t markets efficiently educate / train the workforce?

• Trained people may leave the firm, taking their skills elsewhere

• Missing market:– “Futures market for labor”

• Externalities from education?

28

Economies of scale &/or experience can lead to:

• Oligopoly, market power

• Barriers to entry

• First mover advantages

29

Suppose an industry where market-demand supports only one firm (high tech – e.g., aircraft)

PRODUCE NOT PRODUCE

PRODUCE – 5, – 5 100, 0

NOT PRODUCE

0, 100 0, 0

What are the two EQUILIBRIA? (R,C)

US firm

30

Equilibrium:

• An outcome where no player has an incentive to deviate from his or her chosen strategy given the strategies of the other players.

Now suppose the US moved first, but Europe offers a subsidy… (R,C)

PRODUCE NOT PRODUCE

PRODUCE – 5, 5 100, 0

NOT PRODUCE

Take-aways

• What do governments want? Survival• Democracy v. Autocracy• Malapportionment• Why does the state intervene?• Infant Industries• Economies of Scale• Increasing returns to scale• Economies of experience• First mover advantages• Equilibria
