2. Research questions
1. How much will poverty decline under Ethiopia’s current growth
path?
2. What is the growth and poverty impact of increasing yields and
productivity for different crops and livestock sub-sectors?
3. Which crops and agricultural sub-sectors are best at generating
national growth and/or poverty reduction?
• These are some of the key strategic questions asked by NEPAD as
Ethiopia’s prepares to join the Comprehensive African Agricultural
Development Program (CAADP)

3. Economywide model structure (1)
• Dynamic CGE model (2005-15)
• New 2005 EDRI SAM of Ethiopia
• 24 agricultural sectors
– Based on district crop and livestock data
– Calibrated to observed yields/land areas
– Regionalized (based on agro-zones)
• 14 upstream processing sectors
• 31 other nonagricultural sectors
• Detailed poor/non-poor households
– Based on 2005 income/expend. survey
– Rural farm (by land size, asset holding)
– Rural non-farm and urban
• Micro-simulation poverty module 3

4. Economywide model structure (2)
Factor market closure rules
• Regional land and livestock (mobile across agric. subsectors)
• National labor (mobile across sectors and regions)
– Five types: agricultural; unskilled; skilled technical; managers; professionals
• National capital (fixed by sector)
– Past investment creates new capital stocks (i.e., dynamic accumulation)
– New capital is allocated based on sector profit differentials
Macro closure rules
• Flexible exchange rate; fixed foreign capital inflows
• Fixed government spending plans; flexible fiscal deficit
• Fixed private savings rates; flexible investment (savings-driven inv.)

5. Baseline or ‘business-as-usual’ scenario
Agriculture
• Land cultivated for each crop follows medium-term trends: total
land cultivated increases 2.6% per year, 2009-2015
• Land growth varies across regions (i.e., 1.2% in rainfall-sufficient
areas, 3.2% in drought-prone areas, 3.7% in pastoralist areas)
• Crop yield increases account for one-third of production growth
• Overall agricultural GDP growth: 3.8% per year (pop growth = 3%)
Non-agriculture
• Based on historical medium-term trends (1998 onwards)
• Manufacturing and services: 8.2% per year

We increase productivity (TFP) growth rates to achieve 2015
regional yield targets identified by the Ethiopia-CAADP team

10. Conclusions
• Agricultural growth has significant poverty-reducing effects,
especially for the poorest households/regions
• Thus an Agriculture Development-Led Industrialization (ADLI)
strategy are sound approaches
• Complementary nonagricultural growth also significantly reduces
poverty by raising incomes and stimulating agricultural demand
• However faster agric. growth will cause national average real prices
of some products to fall (esp. wheat, maize and milk)
• If local marketing constraints are not resolved, localized market
gluts could occur, seriously reducing incentives for production
• Nonetheless, reduced prices of major staples helps reduce poverty
of net food purchasers

11. Next steps
• Investment costs of accelerating growth: Out study examined the
impact of alternative growth options, but we have not yet
compared the investment options/costs required to achieve this
growth (i.e., investment trade-offs)
• Improve estimates of model parameters: We need to strengthen
the econometric estimates for some of the remaining behavioral
parameters (e.g., income elasticities and production technologies)
• Climate change: EDRI and the University of Sussex will estimate the
economic costs of climate change and adaptation investments
(e.g., hydroelectric power etc)
