A decision you can investigate
- Training can raise output per worker, while migration can add workers. New technology is useful only if firms can adopt it and use complementary skills and infrastructure.
- More capacity requires an economic mechanism, not just a spending label.
Build the explanation
- Productive capacity 生产能力 concerns sustainable real output. LRAS can change through technology, productivity, education and skills, regulation and taxation, demography/net migration and competition policy. Labour productivity 劳动生产率 is output per labour input; more workers increase the input quantity, which is a different mechanism. Training and innovation can raise effectiveness; demographic change affects the labour force and skills available.
- Regulation can impose costs but also protect safety, quality or trust; taxation can alter incentives and fund productive services. Competition policy can improve efficiency and innovation when it reduces harmful barriers or market power, but scale and investment incentives matter. Explain the intended capacity channel and the conditions required rather than assuming every deregulation or tax cut shifts LRAS right.
Work through the evidence
- A fictional economy has 100 workers producing 5 real-output units each: potential output=100×5=500 under this simple labour-only model. Training raises output per worker to 5.5 with the workforce unchanged, giving 550. If the workforce then increases to 110 with the same productivity 5.5, potential output becomes 605.
- Combined growth is(605−500)/500×100=21%, not 20%: multiply the 1.10 productivity factor by the 1.10 workforce factor. This model assumes sufficient capital, demand-independent capacity measurement and successful skill matching. If equipment supports only 100 workers, adding people does not automatically realize 605. A demographic headcount change is not necessarily a labour-force change.
What is capacity after training alone in the model?
100 workers times 5.5 output units gives 550.
What is the combined capacity growth with both stated changes?
605/500−1=0.21; the two factors compound.
Any rise in actual output necessarily means the LRAS curve shifted right.
Output can rise through fuller use of existing capacity without changing potential output.
Test the limits
- Policies take time and have opportunity costs. Training quality, participation and suitable jobs matter; technology may require finance, electricity and management. Migration can add needed skills but depends on recognition, infrastructure and integration. An ageing population can affect participation differently from total population.
- Lower compliance costs can help firms, but removing effective standards may create external costs. Competition rules need evidence about market power and entry, not a presumption that size alone is harmful. Distinguish a rightward capacity shift from temporarily fuller use of existing capacity; a lower current unemployment rate does not by itself prove that potential output increased.
Which can prevent workforce growth from realizing the modeled output gain?
Capacity depends on complementary resources and effective use.
Apply and explain your answer
- Why is the combined capacity increase 21% rather than the sum of two 10% changes?
- The workforce increase applies after productivity rises, so the changes compound:1.10×1.10=1.21.

Use each term for its stated economic relationship.
Use the terms precisely
- labour productivity: Real output per unit of labour input over the stated period.
- productive capacity: The output an economy can sustainably produce with its resources, technology and institutions under the stated conditions.
