The level of uncertainty will depend on several factors: the nature of the functional form used in the multivariate analysis; the type of econometric technique employed; the appropriateness of the statistical assumptions embedded in the model or technique; the comprehensiveness of the variables included in the analysis; and the accuracy of the data that are utilized. [...] The deterioration in labour productivity growth from the 1960s to the 1970s resulted primarily from the slowdown in MFP growth from 1.5% to 0.2%, and to a lesser extent, a slowdown in the growth in labour composition due to a slower growth in skilled labour (from 0.7% to 0.2%). [...] The slowdown in labour productivity from the 1970s to the 1980s, from 2.0% down to 1.4%, was primarily the result of a decline in the growth in capital intensity and, to a lesser extent, to a decline in MFP performance. [...] This decline is due to a decline in the growth of capital intensity and a much larger decline in MFP growth.8 The decline in MFP growth accounted for 65% of the decline in labour productivity growth from the 1988-to-2000 period to the 2000-to-2005 period. [...] Analysis in the productivity program, as is the case elsewhere in the National Accounts, is an extension of the particular nature of the production process.
