Assorted links

1. Greg Mankiw on income inequality (pdf).

2. Elysium official trailer #2.

3. Mistakes in German architecture, a three-way interview.  Pretty amazing, and full of lessons about management and infrastructure and social capital and fiscal policy and principal-agent problems, not to mention the future of Europe: “The pure truth doesn’t get you far in this business.”  Too instructive to otherwise excerpt.

4. Should China’s credit boom have people worried?
