Abstract
We consider three states which are likely to be realized in bi-layer quantum Hall systems at total Landau level filling fraction . Two of these states may be understood as paired states. One can occur as an instability of a compressible state in the large limit, where and are the interlayer distance and magnetic length. The other is the state, which is expected in the small limit. We propose that the longitudinal and Hall drag resistivities can be used to distinguish these different quantum Hall states. The drag resistivities may be computed in a straightforward manner using the paired state formulation.
