The answer, of course, is
RTFP, which is euphemistically translatable at "read the fine print," a variant of the hoary computer put-down of RTFM.
If the production function is assumed to be Cobb-Douglas and its parameters are assumed to be the same in the two countries, then relative total factor productivity in the two countries, RTFP, can be estimated using the following equation:
so that RTFP measures the residual relative labour productivity when account is taken of differences in capital intensity in the two countries The average value of [alpha] in 1987 was 0.
