ABSTRACT
This investigation was a part of a comparative study of the three multiregional input-output (MRIO) models: column coefficient, row coefficient, and gravity coefficient. 1 The objectives of the research were twofold: (1) to examine the causes underlying negative values in the inverse generated by the row coefficient model, as well as negative projection generated by the model; and (2) to explain why the column coefficient model did not present any of these problems.
