3. Outline
• Background
• The Productivity measures of National Accounts
• The Methodology and what has changed
• Some results

4. Background
• Productivity measures published since 2005 – time for
renewal
• National Accounts change of publication dates affects the
publication of productivity measures
• Eurostat supported countries’ efforts to develop these
calculations

5. The KLEMS Methodology and what
has changed
• KLEMS is an international framework used to examine productivity measures.
• KLEMS is based on growth accounting method.
• Commonly, the main focus is on capital, labor and multifactorproductivity.
• Statistics Finland produces productivity statistics based on KLEMS framework and
data from National Accounts.
…What has changed?
• The publication of productivity is synchronized with the annual NA.
• Publication timeline is renewed
• Technical system and theoretical methodology has been revised and updated.

6. Closer look at changes
• Publication twice a year
• Preliminary results synchronized with NA preliminary publication (June, statistical year
t-1)
• Final results based on NA final publication (March, statistical year t-2)
• Non-market producers are excluded (producer type T30)
• Agricultural sector is excluded (industries 01_03 NACE Rev. 2)
• The net stocks of the national accounts were introduced as the basis for calculating
the productive capital stock.
• In calculation of quality adjusted labor input (QALI) the newest 1-2 years are based
on Labor Force Survey (LFS).

Labour input Capital input
Stock measures Human capital Physical capital
Services to production from
input factors:
Quantity Labour services,
measured as hours
worked
Capital services
Prices Compensation per hour User cost of capital
per unit of capital
service
Differentiation By industry and by type of
labour input
By industry and asset

Factor cost or factor income Compensation per hour *

10. Contribution of capital intensity to the
productivity of labour

Statistics Finland
17 October, 2021
• When the productivity of labour changes,
how much of it is due to the fact that the
amount of capital services in use per hour
worked changed?
• Contributions of capital intensity are now a
little bit smaller than in the previous version
(non-market producers not included in the new
series)

National
Accounts
• Hours worked
• Labor compensation
Distributions
from
Empl.Stat
and LFS
• Data on hours worked and labor
compensation assigned into labor
type groups.
14. Quality adjusted labor input
∆𝑙𝑛𝐿𝑗,𝑡 = σ𝑙 ҧ
𝑣𝑙,𝑗,𝑡 ∆𝑙𝑛𝐻𝑙,𝑗,𝑡= ∆𝑙𝑛𝐻𝑗 + ∆𝑙𝑛𝐿𝐶𝑗
• Interpretation:
1. QALI:
• Tells the magnitude of the contribution of different labor type groups to the total growth of labor input.
• Indicates the development of labor input.
2. Labor quality component:
• Is calculated as residual (weighted hours – unweighted hours, ∆𝑙𝑛𝐿𝑗,𝑡- ∆𝑙𝑛𝐻𝑗)
• Gives the magnitude of the substitution between the different labor types.
• If positive ➔ relative share of high skilled workers or workers with higher relative pay has increased.

15. Changes in calculation of QALI
• Incorporation of Labor Force Survey data into calculation of QALI
• Required: data testing and result comparison
• Achievement: accelerated release frequency
• New publication timeline:
• 15.3.2022
• National accounts revised calculations for year 2020
• Final data of Employment Statistics for year 2019 (QALI)
• Year 2020 from LFS (QALI)
• 30.6.2022
• National accounts preliminary data for year 2021
• Years 2021 and 2020 from LFS (QALI)
