Underdevelopment as
Coordination Failure
• Economic development is difficult to
achieve. It has been impossible for some
countries (e.g., Nigeria, Sudan), but
accomplished by others (e.g., S. Korea,
Singapore)
• The success or failure of economic
development policies can be explained by
the “principal-agent” model.

• Agents:

International companies

Underdevelopment as
Coordination Failure
• An effective principal is needed to
coordinate actions taken by agents and
achieve an optimal outcome, making all
agents better-off.
• Coordination failure occurs when the
principal fails to induce agents to coordinate
their actions, which leads to an outcome that
makes all agents worse-off.

Technological Transfer for
Modernization
• The model is explained by the privately
rational decision function, an S-shaped
curve. The intersection of this curve with the
45º line is the point of equilibrium.
• At equilibrium, the expected outcome of an
action equals its actual outcome

4-7
Technological Transfer for
Modernization
• Stable equilibrium: The S-shaped function crosses
the 45º line from above (points D1 and D3). Here
firms adjust their investment decisions in
coordination with average investment in the
industry.
• Unstable equilibrium: The S-shaped function
crosses the 45º line from below (point D2). As firms
coordinate their investment decisions, equilibrium
moves to D1 (decrease investment) or D3 (increase
investment).

4-8
Technological Transfer for
Modernization
• To achieve stable equilibrium, firms must be
able to coordinate their investment decisions
such that all firms benefit from each other’s
investment.
• Public policy creating incentives for
investment is the key for successful
coordination. The government must
establish inclusive incentives to encourage
business investment.

The Big Push to Industrialization
• A big push to industrialization requires a set
of leading firms to investment in productive
activities and transfer of modern technology
• Investment decisions made by modernsector firms are mutually reinforcing and
public policy intervention is needed to
correct market failure

The Big Push to Industrialization
Assumptions:
•
•
•
•
One factor of production: labor
Two economic sectors: traditional vs. modern
Same production function for each sector
Consumers spend an equal amount on each
product they buy
• Closed economy
• Perfect competition

4-11
The Big Push:
Coordination Failure
• A firm is deciding to invest in new
technology
• It faces a production function in the
traditional sector that passes through the
origin as output increases with labor
employment
• It faces a production function in the modern
sector that requires some labor employment
before initiating production (point F)

The Big Push:

4-13
The Big Push:
Coordination Failure
• At a low wage rate like W1, a new firm will
enter the modern sector after paying the
fixed labor cost (F). With high demand
(Q2), the firm makes profit and invests in
modern technology
• As W2 > W1, other firms enter the modern
sector to share the profit. Coordination
between these firms is now needed for the
economy to adopt modern technology 4-14

The Big Push:
Coordination Failure
• At W2, investment becomes profitable if all
firms invest in modern technology to
industrialize the economy. High demand
for manufactured products makes workers
and firms benefit from capital investment
• At a high wage like W3, investment in
modern technology is not profitable

4-15
The Big Push:
Coordination Failure
• Point A is a stable equilibrium as low profits
discourage firms to invest in modern
technology (no industrialization)
• Point B is an unstable equilibrium because it
requires the principal to provide incentive to
invest and agents to coordinate their
decision of investment in modern
technology (industrialization)

Conditions Making
The Big Push Necessary
• Intertemporal effects: investment in the
modern sector becomes profitable overtime as the market size increases
• Urbanization effects: demand for
manufactured goods increases with
urban population growth

4-17
Conditions Making
The Big Push Necessary
• Infrastructural effects: improvement in
transportation, communication, and
distribution systems reduces the cost of
investment
• Training effects: the labor force
becomes more productive and skilled
with education

4-18
Coordination Problem Cannot Be
Solved by a Super-Entrepreneur
• Capital market failure: bankers are unwilling
to provide loans to a single firm
• Cost of monitoring managers: expensive
agency costs to ensure compliance of
employees
• Communication failure: agents wanting to
share profit cannot convince the superentrepreneur to do so
Copyright © 2009 Pearson Addison-Wesley. All rights reserved.
4-19
Coordination Problem Cannot Be
Solved by a Super-Entrepreneur
• Limited knowledge: agents do not have
sufficient information about the importance
of industrialization
• Lack of empirical evidence: agents do not
know that other firms are investing in
modern technology

4-20
Further Problems of
Multiple Equilibria
• Linkages: underdeveloped backward and
forward linkages to support industrialization
• Inequality and growth: trickle-up growth,
resulting in increased inequality and poverty,
reduces the buying power of workers and
their demand for manufactured goods

4-21
Further Problems of
Multiple Equilibria
• Inefficient advantages of incumbency:
existing firm have lower production cost
• Behavior and norms: agents may be corrupt
and bribery may be the standard method of
doing business internationally

4-22
The O-Ring Theory of
Economic Development
• Production is modeled with strong
complementarities of inputs (labor & capital)
and interdependencies among firms (output
of one firm is input of another)
• Positive assortative matching in production:
skilled labor works with its peers; profitable
and modernizing firms coordinate with their
counterparts
Copyright © 2009 Pearson Addison-Wesley. All rights reserved.
4-23
The O-Ring Theory of
Economic Development
• Implications of strong complementarities for
economic development and the distribution
of income across countries will induce
countries at the same level of development
to coordinate their actions
• MDCs cooperate and coordinate with each
other in the development and transfer of
modern technology

4-24
The Growth Diagnostics Framework
• Focus on a country’s most binding constraints
of economic development: low rate of return
on investment and high cost of financing
• No “one size fits all” in development policy of
market coordination
• Insufficient investment in physical, social,
environmental, and human capital
