Sectoral Contributions to Labour Productivity Growth: Does the Choice of Decomposition Formula Matter?
AbstractUsing three decomposition formulas (TRAD, CSLS, and GEAD), this article estimates sectoral contributions to business sector labour productivity growth in Canada during the 2000-2010 period. Although at the aggregate economy level there was substantial agreement among the three formulas - with most of business sector labour productivity growth being explained by within-sector productivity improvements -, contribution estimates varied widely at the sectoral level. In particular, there were signi cant differences in the estimated contributions of construction, manufacturing, and mining and oil and gas extraction. Ultimately, these differences refl ect the fact that traditional decomposition formulas (TRAD and CSLS) and the GEAD formula measure distinct economic phenomena. Instead of seeing estimates constructed by the GEAD and traditional formulas as "competing" narratives, the article concludes it is more useful to see them as providing complementing stories about the role of di erent sectors in driving aggregate labour productivity growth.
