Economic Conditions and Male Attraction

Alex Tabarrok:

The Environmental Security Hypothesis says that in tough times men will prefer women who are good at production, generally older, taller, heavier, less curvaceous women with less body fat. In good times, they will prefer women who are good at reproduction, generally younger, shorter, lighter, more curvaceous women.

Is it more a matter of what kind of women men prefer or what kind of women they can afford in changing economic times?
