Men who plan to have multiple sexual partners are far more likely to pursue a reckless fiscal policy than men who plan to have few partners. This according to University of Michigan researcher Paul Kruger.

Kruger claims that taking fiscal risks shows females and competing males that you’re rich and powerful.
