From page 66...
... There has not been a comprehensive comparison of the use of iterative proportional fitting or related methods on unconstrained statistically matched files with constrained statistical matching, though Rubin's argument encourages this comparison. This trade-off of computational ease and nearest-neighbor matching versus the maintenance of marginal distributions has resulted in several compromises between unconstrained and constrained statistical matching.
