Recently there has been a renewed research interest in the properties of non-survey updates of input-output tables and social accounting matrices (SAM). Along with the well-known scaling RAS method, new procedures related to entropy minimization and other metrics have been suggested, tested, and used in the literature. Whether these procedures will eventually substitute or merely complement the RAS approach is still an open question. In general, the performance of the updating procedures has been tested using proximity measures to a reference input-output table or SAM. In this paper, in contrast, we propose to look at the operational performance of three updating mechanisms by comparing the simulation results that ensue from adopting alternative databases for the calibration of a reference computable general equilibrium (CGE) model.
