Introduction Slide – Structural Change in the Economy: Sectoral Shifts Over Time
Overview of Structural Change in the Economy and Sectoral Shifts.
Overview
- Structural change refers to the long-term shift in the composition of economic output from agriculture to industry and services.
- Understanding these shifts is critical as they drive productivity growth, economic development, and impact labor markets.
- This presentation covers the causes, implications, and dynamics of sectoral shifts over time on productivity and employment.
- Key insights include the role of labor reallocation, productivity effects within and between sectors, and policy considerations.
Key Discussion Points – Drivers and Implications of Structural Change
Fundamental drivers and effects of sectoral economic shifts.
- Structural change is driven by shifts in relative productivity and domestic prices that lead to labor moving from low productivity sectors like agriculture to higher productivity sectors such as industry and services.
- Technological advances and sector-specific demand changes alter labor skill requirements and relative wages.
- Labor reallocation raises overall productivity but may cause transitional unemployment and require retraining efforts.
- Sectoral shifts influence economic growth patterns and poverty reduction differently depending on the nature of the growth source.
Main Points
Graphical Analysis – Sectoral Output Shares and Productivity Growth Over Time
A visual representation of sectoral output shares and labor productivity trends.
Context and Interpretation
- This chart depicts the decline in agriculture’s share of GDP and employment accompanied by growth in industry and service sectors.
- Labor productivity grows faster in industry and services, demonstrating within-sector improvements and between-sector reallocation effects.
- Risks include lagging labor mobility or skills mismatch delaying structural transformation.
- Insight: Efficient resource reallocation is essential to sustain long-term growth and structural change benefits.

}Analytical Summary & Table – Productivity Contributions of Sectoral Shifts
Quantitative insights into labor reallocation and productivity growth.
Key Discussion Points
- Between-sector labor shifts (from agriculture to industry/services) contribute significantly to aggregate productivity growth.
- Within-sector productivity improvements also drive growth, highlighting technological progress.
- The balance of labor reallocation and productivity gains shapes structural change impact on economic growth.
- Limitations include potential transitional unemployment and unequal skill adjustments.
Illustrative Productivity Contribution Table
Contribution to annual productivity growth by sector and source (percent).
| Sector | Within-Sector Improvement | Between-Sector Reallocation | Total Contribution |
|---|---|---|---|
| Agriculture | 0.5% | -0.3% | 0.2% |
| Industry | 1.2% | 0.6% | 1.8% |
| Services | 1.0% | 0.7% | 1.7% |
| Total | 2.7% | 1.0% | 3.7% |
Graphical Analysis – Labor Reallocation and Skill Composition
Context and Interpretation
- This flow chart illustrates labor movement from primary to secondary and tertiary sectors and the corresponding skill level changes.
- Trends show increasing demand for higher-skilled labor in industry and services, impacting wage structures and education needs.
- Risk factors include mismatch between labor supply skills and sector demand, causing structural unemployment.
- Key insight: Skill development and retraining are critical policies alongside structural economic shifts.

Key Takeaways
- Structural changes drive long-term economic growth but require labor market adaptations.
- Reallocation effects improve productivity but create transitional labor challenges.
- Policymakers should focus on skill development and smoothing employment transitions.
Conclusion
Summary and next steps for understanding structural economic change.
- Sectoral shifts from agriculture to industry and services underpin economic transformations.
- Both between-sector labor reallocation and within-sector productivity gains drive growth.
- Skill mismatches and transitional unemployment are key risk factors during structural change.
- Recommendations include enhanced education, workforce training, and policies promoting smooth sector transitions.
