Three types of countries
• Coastal countries strongly exposed to urban bias (Senegal, Liberia, Cote d’Ivoire, Ghana, Togo, Benin, Nigeria, Cameroon)
• Coastal countries not yet strongly affected by urban bias or with comparative advantage in rice demand (Gambia, Guinea, Sierra Leone, Kenya, Tanzania, Mozambique, Madagascar)
• Landlocked countries (Mali, Burkina Faso, Ethiopia, Rwanda, Zambia)
Third Africa Rice Congress, Yaoundé, Cameroon, 21–24 October 2013
Observation
• In many import-biased countries endowed with a port, domestic rice fails to compete quality-wise with imported Asian rice
• As a result of urban bias, urban consumers have become used to the superior quality of imported Asian rice and developed preferences for it
Third Africa Rice Congress, Yaoundé, Cameroon, 21–24 October 2013
Observation
• Domestic rice clearly differentiated from imported rice– Quality-wise– Packaging, branding, image– Word-of-mouth– Status considerations (foreign = cool)f-mouth– Status considerations (foreign = cool)
Third Africa Rice Congress, Yaoundé, Cameroon, 21–24 October 2013
Which ones are domestic rice?
Third Africa Rice Congress, Yaoundé, Cameroon, 21–24 October 2013
Research hypothesis
• Domestic rice now not only has to compete quantity-wise, but also quality-wise, but how?
• In the absence of strong consumer attachment to domestic rice, best short- and medium-term option = dedifferentiating domestic from imported rice– Quality-wise– Packaging, branding, image
Third Africa Rice Congress, Yaoundé, Cameroon, 21–24 October 2013
Research hypothesis
• Proposed three-stage investment sequence for upgrading rice value chains in import-biased countries strongly exposed to urban bias:
Quality upgrading, processing infrastructure, certification, branding, ...
Quantity increase, scaling up, aggregation and storage infrastructure
Advertizing and generic promotion
Value-adding
Demand-lifting
Supply-shifting
Third Africa Rice Congress, Yaoundé, Cameroon, 21–24 October 2013
How can we test this hypothesis?
• Can experimental economics help?• Experimental auctions enable assessing
consumers’ response to upgrading of1. Intrinsic quality attributes:• Post-harvest quality upgrading• Varietal improvement
2. Extrinsic quality attributes:• Labeling and branding• Information (radio, video, word-of-mouth)

Case studies

quality rice in Burkina FasoThis presentation:3. Dedifferentiating imported from local rice in

Rice quality upgrading in Cameroon
• Institute of Agric. Research for Development (IRAD), Cameroon developed uniform steam distributed (USD) parboiling technology
• Mimics high-grade imported rice in physical and eating characteristics:– Whiter– Lower broken fracture– Fewer cracked grains– Absence of burnt grains and impurities– Higher swelling ratio during cooking

Rice quality upgrading in Cameroon
IRRI Seminar, International Rice Research Institute (IRRI), Los Baños, Laguna, Philippines, 4 April 2013
Research questions
• Do consumers perceive the IRAD rice as being similar to imported rice?
• Are they willing to pay price premiums for it? Relative to– Traditionally parboiled local rice– Improved non-parboiled local rice
• Did IRAD technology successfully quality-dedifferentiate domestic from imported rice?

Setting up laboratory setting

Choosing products to be auctioned• Kept the varietal component constant• Using a single rice variety: Tox 3145• Processed into four different end-products

Upgrade 3: improved parboiled rice (IRAD)
Upgrade 2: traditionally
parboiled (TRAD) rice
Upgrade 1: non-

Conclusion
• Consumers are 14% more likely to upgrade to improved parboiled rice (IRAD)
• Those who perceive IRAD rice as being imported (63%)– Paid 5% price premiums for IRAD rice– Discounted traditionally parboiled rice by 2%
• Major value of IRAD technology = ability to successfully quality-dedifferentiate domestic from imported rice in urban markets in Cameroon
