"On the Efficiency of AC/DC:
Bon Scott versus Brian Johnson"

Thus, in terms of a singer’s ability to implement efficient behavioral outcomes among listeners, our results suggest that Brian Johnson was a better vocalist than Bon Scott.

I think the trend toward economists studying silly topics may have gone too far. Don't we still need people to look into minor questions like how do changes in income tax rates effect GDP growth? This comes via Tyler Cowen, whose blog I now fear may be helping to encourage a more-than-optimal level of silly research.
