Objective(s)
Key Observations
Imperial
Regime
Support and promote the
interests of few landlords
and urban consumers
Limited interventions and were not
effective
Socialist
Regime
Complete socialization of
production and marketing
Heavy government intervention
which depressed the development
of private grain trade
The Current
Regime
Price stabilization,
promote private sector
grain trade
Progresses have been made.
However, good intentions are
frustrated with ad hock nature of
policy interventions
Review of Grain Marketing Policy Changes in Ethiopia:
Objectives and key Observations
Policy reviews: key lessons
Ad hock nature of policy interventions No sufficient details in the design and implementations
No sufficient resources assigned to implement the planned policy interventions
Policy not implemented or not effective
Created uncertainty in the market which affects private sectors optimal operational and investment decisions
Eroded public confidence in governments’ intervention measures
Grain marketing policies have been designed with too many objectives, which are often conflicting For example, the EGTE has been expected to be commercially
profitable while at the same time to meet social objectives of price stabilization under tight financial support from the government Price stabilization requires sufficient working capital and stocks –
adequate budgeting of policy interventions

Performance: market integration concept
Consider the following facts: In 1985, price of kg of teff was 7.7 Birr in Gojjam BUT 15.7
Birr in Wello
In 1974, price of rice in the district of Rangpur in
Bangladesh (a deficit area) was almost three times the
prices in surplus and well developed districts
What is common in these two cases? Both countries had famines: Ethiopia in 1984/5 and
Bangladesh in 1974.
Hard hit famine areas lacked integration with the surplus
and well developed regions.
In both countries there were restrictions on grain
movements
Performance: market integration review

Method of analysis Findings
Dadi, L., A. Negassa, and S.
Franzel. 1992.
Maize and Teff Bako area of Western Shoa and
Eastern Wollega
(1985 -1989)
Price correlation analysis Results indicate that private sector marketing of maize and teff is
characterized by high risk and variable gross margins. Interspatial arbitrage
is serious flawed, correlations in prices range from weak to strong
Dercon, S. 1995. Teff Ethiopia
(1987 – 1993)
Modified Ravallion’s method Liberalization had important effects on the long-run and short-run
integration of markets: most teff markets were c- integrated with Addis
Ababa market
Negassa, A. 1996. Maize, teff,
Noug and
Sorghum
Bako area of Western Shoa and
Eastern Wollega
(1986 – 1993)
Price correlations, Granger’s
and Johansen’s co integration
methods
Deregulation has resulted in an increase in real prices accompanied by an
increase in price variability. Price correlation and Granger methods show
improvement in market integration while Johansen method shows no
significant changes.
Negassa, A. and T. Jayne. 1997. Maize, teff, and
wheat
Ethiopia
(1985 – 1996)
Variance and price correlation
analyses
Cereal price spreads have generally declined since reform. While prices in
surplus producing areas have risen by 12 – 48 percent; prices in deficit
regions declined by 6 -36 percent.
Getnet, K. Verbeke w. and J.
Viaene. 2005.
Teff Ethiopia
(1996 – 2005)
Autoregressive distributed lag
model
Found long-run and short-run relationship between producer prices and the
wholesale price in major terminal market (Addis Ababa)
Getnet, K., E. Gabre-Madhin, S.
Rashid., and S. Tamiru. 2006.
Wheat Ethiopia
(1996 – 2006)
Granger cointegration and
error-correction and Johansen
cointegration methods
Some markets share a common factor but the price dynamics in the entire
market considered are not as such influenced by single common factor.
The implication is that different markets need different policy instruments
to address the price stabilization issues
Negassa, A. and R. Myers. 2007. Maize and
wheat
Ethiopia
(1996 – 2002)
Extended parity bounds model Grain market reform have improved spatial market efficiency in a few
markets, worsened it in a few others, but generally to have had little effect
on the spatial efficiency of Ethiopian grain market
Rashid and Gabre-Madhin, 2007. Maize, wheat,
and teff
Ethiopia
(1996 – 2006)
Common trend and
Multivariate co-integration
analyses
Most market locations, except one in the north and another in the eastern
part of the country, are integrated. Analyses of common trends indicate that
shocks to teff markets have little effects and shocks to maize markets have
more persistent effects on the other commodities.
Performance: Seasonality and variability
Basics concepts of seasonality & variability
analyses
Any time series variable can be represented as
follows:
Where T = Trend component; C= Cyclical component
S = Seasonal component; and I = Irregular component
Decomposing these components is essential in
seasonality and variability analyses!!
ISCTt
X
Performance: seasonality analyses
Centered moving averages eliminates
Seasonal and Irregular components from the
time series.
That is, CMX = T x C.
Dividing Xt by CMX leaves seasonal and irregular
components.
By doing one more adjustment, the irregular
component can be eliminated; and we are left with
seasonal index.

Three things we can do with the estimated
seasonality indices
Future price projection
Competitiveness in storage behaviors
Tests for the change in seasonality patterns
Future price projection
Suppose we want to project August price of teff in
January based on the following info:
price of teff in January is 350 Birr /quintal
Seasonal indices for January & August are 0.95 & 1.1,
respectively.
August price will roughly be ____!!!
Performance: seasonality
Competitiveness in storage
Suppose someone wants to make profits by buying
maize when prices are low and selling when prices
are high
Also suppose
The minimum and maximum seasonality indices are 0.93 and
1.1, respectively.
The trader need to store at least for six months to make profits
Maize loses 5 percent weight in six months
Trader borrowed money from bank at an interest rate of 12%.
Is this trader’s storage competitive or is he making
excess profit!!

What would have been the maize price in 2008 if
there had been no change in transaction costs?
Total transaction costs in1996 was 28 percent of
wholesale price
Price of maize in 1996 was 750 Birr per ton
In 2008, price of maize was 4170 Birr per ton; and
transaction costs was less than 3 percent of the
wholesale prices.
If transaction costs had remained the same,
prices in 2008 would have been ______!!
What do estimates of costs and margins mean?
Let’s do some math!!
