Germany's success

Here is an article that can be summarised with your reflections.

Hans Rosling on global population growth

Here is the link for the presentation we watched together.  You can listen to it at your convenience as you take notes for a summary report if you could not do this exercise in the first part of the course.

Streams and texts for summary reports

As we discussed, I am hereby making two streams and two articles for you to watch and listen to respectively for a summary report followed by your reflections, which you may leave out if you want to.  This, of course, is an optional exercise; you can choose the one(s) you like the best if you do not have the time to do all of them.  You can send me your summary reports at your convenience before our next session on Monday, 21st of November.

Here are the two talks:
Charles Leadbeater on innovation
Yochai Benkler on the new open-source economics

Here are the two articles:
Globalization's Missing Middle
The Impact of Globalization on Income and Employment
