A comparison of estimators of output multipliers from incomplete input-output data
Abstract This paper presents derivations and empirical tests of three formulas for estimating output multipliers with only limited input-output type data. The first formula assumes only knowledge of the proportion of the value of output of the firm or industry in question which is respent within the region, as well as an estimate of the average of this value over all industries. The second formula assumes this value as well as the relative values of the I-O “row totals.” The third equation assumes data equivalent to a column in the I-O matrix is known for the specific firm or industry in question. The data requirements for all three formulas are modest but are more for (2) than for (1) and are more for (3) than for (2). All three formulas are shown to be quite reliable but the third gives especially close estimates of the actual multipliers for the several models tested. It is concluded that fairly rough estimates of the average interindustry proportion can be safely used but it is important to obtain the firm or industry expenditure (direct effects) data as accurately as possible.
