I'm not an economist, so I could be wrong. Austrians say they use praxeology. They approach economic problems through deduction. This should make some of their theories falsifiable. After all, if you can't find evidence for the notion of opportunity cost, then it can't be a valid concept. I think that the problem with Austrian economics is that relying on praxeology and deduction is like doing theoretical physics - you make assumptions, do logic based on those assumptions and see if it fits the real world. It can work, but it's slow.
