1. Barter continues to grow in Greece.  And the FT on Sardex in Sardinia.

2. What happens when Australians allow markets in everything.

3. Does social responsibility lower risk-taking behavior?  Paper is here.

4. In most plausible models, is Volkswagen the only car-maker to have rigged emissions data?
