Sector Productivity Contribution: Estimate a sector's weighted contribution to aggregate labour-productivity growth.
Age 5Explain it to a 5-year-oldStart with a picture
Imagine using Sector Productivity Contribution to answer this question: estimate a sector's weighted contribution to aggregate labour-productivity growth? Enter Sector employment share, Sector labour-productivity growth, Economy-wide productivity growth, and 1 other input; the calculator shows Sector contribution to productivity growth. Try changing one number and watch what happens to Sector contribution to productivity growth. The answer tells you Sector contribution to productivity growth.
Age 15Explain it to a 15-year-oldConnect it to the formula
Reallocation between sectors creates an additional effect not captured by a fixed employment-share contribution. The rule is Sector contribution = employment share × sector productivity growth. Its input values are Sector employment share (%), Sector labour-productivity growth (%), Economy-wide productivity growth (%), Sector employment-share change (%), and the main result is Sector contribution to productivity growth. Try changing one number and watch what happens to Sector contribution to productivity growth.
CollegeExplain it at college levelState the model precisely
This calculator evaluates a macroeconomics relationship while holding unmodelled conditions constant. The implemented relation is Sector contribution = employment share × sector productivity growth, evaluated from Sector employment share (%), Sector labour-productivity growth (%), Economy-wide productivity growth (%), Sector employment-share change (%) to produce Sector contribution to productivity growth. Reallocation between sectors creates an additional effect not captured by a fixed employment-share contribution. The result depends on comparable definitions, units, populations and time periods. It estimates a relationship; it does not establish causation or replace current primary data.
The economic question
Estimate a sector's weighted contribution to aggregate labour-productivity growth.
Why this relationship is useful
Reallocation between sectors creates an additional effect not captured by a fixed employment-share contribution.
Inputs that must be comparable
- Sector employment share measured in %.
- Sector labour-productivity growth measured in %.
- Economy-wide productivity growth measured in %.
- Sector employment-share change measured in %.
Use one market, firm, population and time period throughout; mixing definitions can make a correctly calculated number economically meaningless.
The model
Sector contribution = employment share × sector productivity growth
From inputs to output
The calculator combines Sector employment share, Sector labour-productivity growth, Economy-wide productivity growth, Sector employment-share change and reportsSector contribution to productivity growth together with Share of aggregate productivity growth, Approximate employment reallocation signal. Change one assumption at a time to identify what actually drives the estimate.
How to read Sector contribution to productivity growth
Read the sign, magnitude, unit and period together. The result quantifies the relationship in “estimate a sector's weighted contribution to aggregate labour-productivity growth”; it does not by itself prove that one input caused another.
Where interpretation can fail
Do not use the result when the input definitions, units or formula assumptions do not match the real situation. This is an educational model, not financial, investment, tax or policy advice; verify material decisions against primary data and professional guidance.
