Gijbels et. al. Positive quadrant dependence tests for copulas (25 page PDF)

What could potentially be application of this concept in economics and finance? From what I read from a couple of papers, they seem to be useful for modelling probabilities of consecutive portfolio losses in credit and insurance.

Can you guys think of anything else? Any use in hedging?

Also, how to compute positive orthant dependence? Any software available?
