Modeling cultural differences with economics
Marginal Revolution's Alex Tabbarok has a nice discussion of a paper on cultural differences in tardiness, or its inverse, "Punctuality" by economists Kaushik Basu and Jorgen Weibull. As societies develop, it seems to me that the benefits from adopting a punctual norm increase, but these changes are not easily achieved. I recommend Alex' discussion. The paper is linked there, but it is somewhat technical and likely to be of interest only to economists.

Craig Newmark has some truly funny quotes from a speech Gates gave at the University of Illinois.
