A note on the GRAS method

The GRAS method as presented by Junius and Oosterhaven (2003) assumes that every row and every column of a matrix to be balanced has at least one positive element. This might not necessarily be true in practice, in particular, when dealing with large-scale input-ouput tables, supply and use tables, social accounting matrices, or, for that matter, any other matrix. In this short note we relax this assumption and make available our MATLAB program for anyone interested in matrix GRASing. The same issue arises in the presentations of the KRAS method (Lenzen, Gallego and Wood, 2009) and the SUT-RAS method (Temurshoev and Timmer, 2011), which should be accordingly accounted for in their empirical applications.
