Emerging countries will need to find their voice and play a more assertive role. They have always been in the position to react to proposals, but they will increasingly need to come up with global solutions themselves.

There is still a reluctance to fully accept the fact that the world is bigger now and there are more seats needed at the table of global governance. It is healthy that emerging markets have increasing influence and global governing bodies should change to reflect this.

The second lesson is that there are enormous vulnerabilities in the integrated financial system and the world lacks the governing system to keep this under control. Ultimately this is an example where institutions are running far behind the actual economy. They need to catch up. We need better global governance and Europe is the perfect example.

Instead of pulling back and thinking that governments need to leave it to the markets, the solution is to fix the governance issues.

And finally, high-income countries are in envy of the success of emerging markets and they try to understand what makes them so successful. Part of that success is just that developing countries are catching up, but part of it is also that there is better focus on long-term strategies in emerging economies. This is something that is missing in high-income countries today.
  We have confirmed that fiscal stimulus and monetary stimulus are needed in times of crisis. By acting promptly and avoiding protectionism stimulus helped the world to avoid a depression a few years ago. But we have also learned that once you have the fiscal stimulus, withdrawing the fiscal stimulus is very hard.

Fiscal stimulus is meant to be timely, temporary, and targeted. This means it’s easier to have automatic stabilizers or enough safety nets built into the system. When the economy slows this kind of spending increases automatically, and when economic growth accelerates again there is a gradual withdrawal. Unfortunately, this is not the case in the United States—all of the decisions are held hostage to the politics of the day.

Finally, in my view the crisis has confirmed the importance of flexible exchange rates. The European crisis has shown that if countries are going to fix their exchange rates they need to do many other things to support the system.  MORE►
