Questions & Arguments

Why did emission standards diffuse?
Countries adopted standards to enhance the
competitiveness of their auto industries.

What happens after adoption?
Except for low-income countries, automobile exports
increase.
Question
Methodology

Analysis 2
Conclusion
Mechanisms of Diffusion

4 major mechanisms in the Policy
Diffusion literature:
• Competitiveness
• International Pressure
• Normative Emulation
• Learning

The “California Effect” (Vogel, 1997)
Question
Methodology
Analysis 1
Analysis 2
Conclusion
Competitiveness Mechanism

The California Effect
• Exporting countries adopt emission
standards when major importing countries
adopt standards

Competitor Effect
• Exporting countries adopt emission
standards when competing exporting
countries adopt standards

Interpretations


Competitiveness appears to be the
major factor for standards adoption
High-income countries
• “California effect” & “Competitor effect”

Developing countries
• Upper-middle: “California effect”
• Lower-middle & Low: “Competitor effect”

Conclusion
Qualitative Evidence

78 interviews in China and Japan
• Managers in the automobile industry
(Honda, Toyota, Hyundai, GM, VW, Geely)
• Government officials (national and local)
• Researchers at national institutions, think
tanks, and universities
Question
Methodology
Analysis 1
Analysis 2
Conclusion
Qualitative Evidence

Main findings
• Japanese government pushed automobile industry
to develop technologies
• Japanese auto industry opposed adoption of
standards
• Chinese government adopted the standards to
reduce air pollution and to increase auto industry
competitiveness
• Foreign-venture automobile firms in China lobbied
Beijing to adopt European standards
• Difficult for local automobile industry to meet the
requirements

Conclusion



Competitiveness is the major mechanism
Market incentives lead to more stringent
environmental standards
Stringent emission standards
 better environment, less premature

Policy Implications


Other “environmentally friendly”
products may also create competitive
advantage
Policy diffusion may apply to….
• Product Standards for Appliances
• Energy Efficiency Standards

Developed countries can influence
developing countries’ behavior
