Market failure focus
Goal: making commodities markets function for the poor at local, regional, and international markets by:
• Releasing constraints to participation • Enhancing benefits from participation (better income
and nutrition)
Major Market Failures:• Externalities (+/-)• Merit and demerit goods• Public goods• Information asymmetry• Monopoly (monopsony) power• Government failure
inefficiency and high
transaction costs

But
• The Challenge: Income growth and market development are not sufficient to improve nutrition and food safety.
• The Opportunity: Can value chain research improve market performance but also for nutrition and food safety?

Income Growth Can Reduce Child Stunting, But Other Actions Needed
A 10% increase in GDP/PC
leads to a 6% reduction in
stunting

Income Growth Can Increase Risks of Overweight and Obesity
A 10% increase in GDP/PC
leads to a 7% increase in overweight
and obesity in women

Inputs into production
Food production
Food storage and processing
Food distribution and transport
Food retail and labeling
Value Chain Approach
Consumer
Producer
Supply side
Develop and test solutions
Demand side
Characterize diets, market access and constraints to
consumption of nutritious, safe foods
Test solutions to improve demand for nutrition and
safety along the value chain
Identify production and market constraints to
improved nutrition and safety
Example: Increased seasonal availability of
fruit
Example: Nutrition education delivered by vegetable seed
supplier

Key topics we are focusing
• Nutrition and food safety
• Contract farming
• Farmer groups
• Access to finance
• Access to micro-insurance

Value chain example: the Vietnamese dairy sector
• Archetypal for high-value agricultural markets in DCs
• Domestic demand for dairy products grows quickly
• Atomistic supplier structure• Buyer holds natural monopsony• Sector is dominated by formerly state-owned
Vinamilk

Existing contractual arrangement
Factors constraining farm productivity:
“Usual suspects”: infrastructure, access to inputs/credit, skills
But also contractual design and institutions?
— Lack of transparency: quality is assessed by the company

Research project and research questions
Research questions:
Does provision of 3rd-party quality assessment…
…make farmers produce more and higher quality milk?
…increase welfare levels of farming households and of the dairy processor?
Field experiment:
• Through collaboration with Vinamilk we could work with 400 contracted dairy farmers in “natural” setting
![Page 13: Partnership for Impact Event_Brussels-Torero](https://reader035.vdocuments.net/reader035/viewer/2022081518/554960e9b4c905f74e8b5a49/html5/thumbnails/13.jpg)
Experimental Design
i?!
Treatment farmers (n=100) receive vouchers for zero-cost milk testing in independent lab
B-samples taken & transported to independent laboratory
Vouchers executed whenever farmers challenge the company’s testing results
Company does not know when vouchers are executed Eliminates opportunistic behavior
![Page 14: Partnership for Impact Event_Brussels-Torero](https://reader035.vdocuments.net/reader035/viewer/2022081518/554960e9b4c905f74e8b5a49/html5/thumbnails/14.jpg)
• Independent quality verification leads to higher input use, more output, slightly higher household welfare in treatment group compared to control group
• Independent quality verification enables the processor to signal its type “fair”
• More transparency in the dairy supply chain– Small-scale dairy farmers gain– Processor gains from lower per-unit transaction
costs when procuring raw material
Main results

• Role for the state in establishing infrastructure for third-party quality verification?
• More competition among buyers of milk would help – Improve contract terms for small-scale farmers– Race to the top with respect to transparency
Policy implications

Health benefits and Agricultural contractsExperimental evidence from Northern Senegal
• Can health-related incentives be used to overcome contract enforcement issues with small-scale agriculture suppliers?
• Can existing value chain logistics be leveraged to increase health conditions in remote locations?
![Page 17: Partnership for Impact Event_Brussels-Torero](https://reader035.vdocuments.net/reader035/viewer/2022081518/554960e9b4c905f74e8b5a49/html5/thumbnails/17.jpg)
Health benefits and Agricultural contractsExperimental evidence from Northern Senegal
• Semi-nomadic milk producers, very remote location
• Milking efforts by women, cash collected by men
• Highly unreliable milk supply, particularly in dry season
• Extreme level of anemia prevalence for children in the area (82% anemic, 15% severe anemic).

Note: Impact parameter estimate for separate impact estimates ran each week. Lowess smoothing function used across estimates. Dahes lines are 95% confidence interval
Note: Generalized propensity score estimate used to deal with endogeneity of treatment intensity. Green and red lines are 95% confidence interval
Clear and significant effect on milk delivery during dry seasonOrder of magnitude: 10 percentage point (=30%) higher contract fulfillment in treatment group in early June.
Positive dose-response effect on children’s health (Hemoglobin level)Order of magnitude: 1.25 g/dl Hemoglobin increase for 16 weeks of continuous fortified porridge intake.

Summary
• Addresses market failures to release constraints faced by smallholders but to enhance benefits
• Although Increased calorie production and incomes is not sufficient and no longer seen as ag’s only role
• We also need to increase diet diversity and consumption of nutrient rich foods
• Is central to identify barriers to greater consumption of nutritious foods
• Tests market solutions to provide better nutrition and food safety
