3. 1. Introduction
- Agricultural productivity increases and modern
input use high on the agenda, especially in Africa;
most promising way to increase agricultural
production is the more widespread adoption of
modern inputs
- However, several constraints to adoption in Africa,
most importantly related to profitability issues and
lack of familiarity of farmers with new technologies
- This paper looks at transaction costs and
transportation costs as a constraint to adoption
(adding to the profitability debate)

4. 2. Background Ethiopia
- Rapid growth in agricultural productivity. However,
modern input use has contributed little to that
growth. As conventional sources of growth are
running out (land), increasing use of modern inputs
in Ethiopia very important
- Ethiopia imported about 500,000 tons for a value of
500 million USD last year; Fertilizer distribution
almost exclusively done by cooperatives; share of
private sector very limited
- Improved seeds low adoption rates; might possibly
be addressed through new seed law that is being
considered

• Households’ circumstances differ because of
different transport costs...
• ...not because of land characteristics, etc.

16. 6. Pricing and profitability
• To get at implicit prices of modern inputs, value
all the transaction and transportation costs
• Value the opportunity costs of time as well
• Transaction costs increase implicit fertilizer
prices by 20% for those farmers living close
• Fertilizer price increases by 100% for the most
remote households

19. Pricing modern inputs
- How important are these implicit costs?
- Costs about 160 USD/ton to bring chemical fertilizer
from Djibouti to rural areas in Ethiopia
- Transaction and transportation for the most remote
areas are thus 3 times as important as bringing
products from international markets to rural areas
- Profitability of modern input use affected by these
transaction costs
19
20. Profitability of fertilizer use
- Profitability of fertilizer use explained by two
factors: 1/ the technical response of output to
fertilizer use; 2/the relationship between output
prices and fertilizer prices.
- The value cost ratio (VCR) often used to evaluate
profitability of fertilizer use. It is defined as:
VCR = (O/N)/(Pn/Po) = (O*Po)/(N*Pn)
where O are the units of outputs produced from
one unit of nutrient, Pn is the price of fertilizer, and
Po is the price of output.

23. 7. Adoption of modern inputs
- Two ways of looking at modern input adoption
- Non-parametric graphs, simple graphs of adoption
as function of remoteness
- Regression analysis (including distance as well as
plot and household characteristics); Use double-
hurdle models:
a. first hurdle: regression of different factors (including
remoteness) on access of modern inputs (yes/no);
b. second hurdle: regression of different factors
(including remoteness) on quantity used of inputs

26. 7. Adoption of modern inputs
Results double hurdle model:
- Use the unconditional Average Partial Effect (APE) to
analyzed impact of explanatory variables
- APE of log(distance) on chemical fertilizer use is
evaluated at -44 and is highly significant, i.e. a
doubling of the distance to the cooperative office
and market (or about 20 kms) reduces the fertilizer
use by 44 kg per ha (ceteris paribus).
- A doubling of the distance reduces the improved
maize seed use by 6 kg per hectare.
26
27. 8. External validity constraints
- To what extent are the findings from this remote
area (and exceptional kebele) in Amhara valid
temporarily (over time) and spatially (for Ethiopia as
a whole)?
- Same questions asked for the year 2011: similar
results
- AGP data (20% of farmers complain of lack of
fertilizer supply; 12% of late supply of fertilizer);
- VCR at distribution center similar to other estimates
(Spielman; Asrat et al.; Tefera et al.)
- Distances of farmers to modern input distribution
centers being calculated 27
28. 9. Conclusions
Our study highlights constraints with respect to two
variables for adoption of modern inputs:
- Transaction and transportation costs limit the
profitability of modern input use
- Profitability a major important determinant in
adoption (indicating that farmers respond to
profitability concerns) (important as credit access or
procastination clearly not only factors)
28
29. 9. Conclusions
Policy implications to improve modern input adoption:
1. Rationing of improved seed in these markets; better
supply chains required
2. Further management capacity building for
cooperatives required
3. De-licensing as to allow for a more competitive
environment in the last mile
4. Further improved transportation infrastructure
needed (importance of feeder roads)
5. Recent policy to move away from credit provision
for modern input acquisition; implications adoption
