After the Fall: Lessons for Policy Cooperation from the Global Crisis Summary

Core Content

This working paper by Tamim Bayoumi analyzes the effectiveness of international economic policy cooperation in the aftermath of the 2007/08 financial crisis. It emphasizes the importance of institutional arrangements and the role of spillovers in shaping the outcomes of policy coordination.

Main Points

1. Definition of Policy Cooperation

Policy cooperation is defined as the process of working together to the same end.
It is less intrusive than policy coordination, which involves organizing different elements to work effectively.
The paper argues that cooperation is more likely when there is a clear consensus on the benefits of consistent policies and when institutional frameworks are more concrete.

2. Institutional Setting

The crisis led to a shift from smaller, homogenous groups (like the G-7) to broader, more diverse groups (like the G-20).
The G-20 became a central platform for international policy coordination, with the 2008 Washington summit marking the beginning of a broader policy agenda.
Institutions like the World Trade Organization (WTO) and the Basel Committee had more inclusive and organized frameworks, which facilitated better cooperation.

3. Short-term Macroeconomic Support

A. Liquidity Support

Central bank swap lines were a key form of international cooperation, providing dollar liquidity to other central banks.
These lines were initially limited but expanded rapidly after the Lehman bankruptcy, becoming permanent by 2013.
The shift from temporary to permanent liquidity support reflects the growing interconnectedness of global financial systems.

B. Monetary Policy

Initially, monetary policy support was primarily U.S.-centric, but after the Lehman crisis, more coordination emerged.
Central banks like the Fed, ECB, and BoJ adopted unconventional measures such as asset purchases and forward guidance.
However, cooperation waned as central banks focused more on domestic conditions, with little mention of global spillovers in their communications.
The 2013 G-20 summit in St. Petersburg marked a slight improvement in acknowledging the importance of spillovers and cooperation.

C. Fiscal Policy

Fiscal stimulus was initially well-coordinated, with a goal of a 2% GDP boost through G-20 cooperation.
The largest fiscal responses came from major economies like the U.S., China, and Germany.
As the crisis evolved, coordination became more difficult due to differing views on the long-term effects of fiscal policy.
There was a growing divide between countries prioritizing short-term stimulus and those concerned about long-term debt sustainability.
The G-20 eventually agreed on fiscal consolidation, but implementation was uneven and often delayed.

4. Financial, Trade, and Policy Mix

A. Financial Sector Reform

The G-20 focused on reforming financial markets to prevent future crises.
Key areas included strengthening capital adequacy, improving risk modeling, and enhancing transparency.
Initiatives like the Fiscal Compact, Six Pack, and Two Pack were introduced to improve fiscal surveillance in Europe.
While many reforms were agreed upon, implementation was inconsistent, and some initiatives were abandoned.

Key Information

Lessons for Policy Cooperation:
- Focus on the potential costs of not cooperating rather than the minor gains from coordination.
- Strive for consensus on spillovers and the risks of inaction.
- Emphasize building more enduring and concrete institutional arrangements.
- Highlight the importance of institutional mandates and legal frameworks in ensuring effective cooperation.
Notable Achievements:
- Expansion of IMF lending capacity to $750 billion.
- Introduction of permanent central bank swap lines.
- Development of a coordinated fiscal stimulus plan.
Challenges:
- Disagreements over the benefits and risks of fiscal expansion.
- Limited focus on international spillovers in monetary policy decisions.
- Inconsistent implementation of financial sector reforms.

Conclusion

The paper concludes that while the global crisis spurred significant policy cooperation, especially in areas like liquidity support and financial sector reform, the effectiveness of such cooperation varied. Areas with clear institutional frameworks and broad consensus on the benefits of coordinated action saw more success. Future efforts to enhance policy cooperation should focus on building stronger, more consistent institutional arrangements and emphasizing the risks of non-cooperation.
