1) The document discusses food safety regulations and dairy value chains in Kyrgyzstan, specifically whether private or government inspections are better for monitoring compliance.
2) A game theoretic model is used to analyze second-party monitoring (by sellers) versus third-party monitoring (by independent auditors or government). More frequent inspections are found to reduce compliance when done by sellers due to wasted monitoring costs.
3) Third-party monitoring can improve welfare by inspecting less frequently but maintaining high compliance, especially when suppliers face greater liability and buyers are more forgiving of occasional low quality.

Food safety, SPS regulations and dairy value chains in Kyrgyzstan: private or government inspections?

Food safety, SPS regulations and dairy value chains in
Kyrgyzstan: private or government inspections?

2. Introduction
Provision of food safety is subject to moral hazard
- consumers learn quality after purchasing
This problem is compounded in developing countries
- unstable supply chains
- limited private liability for health losses
- limited public funding for oversight
Policy question: private or government monitoring of
compliance with food safety regulations?
3. Food safety policy in Central Asia
• important for consumers and producers
• 50% of food exports was SPS-sensitive: meat and
preparations, dairy, eggs, fish, fruits and vegetables
(Kyrgyzstan, 2005)
• access to international markets requires compliance with
SPS and veterinary regulations
• reforms of inspections and food safety standards
4. Government monitoring of agricultural producers in Kyrgyzstan
Investment Climate as seen by Small and Medium Enterprises in the Kyrgyz Republic
(World Bank)
- survey of 623 farmers (owners of private agricultural firms, total 321856) in 2009
- farms are small: annual profit $1200 on sales $3100
- government oversight:
farmers were least subject to inspections
29% were subject to investigation by at least one inspectorate in 2008
- informal payments: 24-44% gave bribes to government officials
- cost of government inspections relative to profit is 2.5%
- current standards for processing firms are particularly burdensome
Quote from the report:
“It is therefore recommended that the Kyrgyz Republic moves away from the
[mandatory government standards and certification] for food products, and ensures
instead (i) that all food business operators implement and adhere to HACCP, GMP
and GHP and (ii) the traceability of all food products, starting with meat and milk.
These approaches are in line with Codex Alimentarius food safety practices.”
5. What determines the choice between private and government inspections?
- intrinsic motivation (public health vs profits)
- monitoring technology (obsolete test for nitrates vs innovation)
- size and scope (69% of permits to farmers were issued by local governments)
Some monitoring is technologically necessary
- testing and grading by fruit size or milk fat content
Some monitoring is technologically unnecessary
- inspections of compliance with food safety regulations
Our focus is compare which inspection system is better:
downstream party inspects upstream party (second party monitoring)
or
government or private auditor inspects upstream party (third party monitoring)

7. Stage game
1. Seller is matched with a random supplier with limited liability
2. Seller privately proposes contracts ),,( lh www and ),,( lh fff
to supplier and monitor
3. Supplier and monitor publicly decide whether to accept contracts
4. Supplier and monitor play a simultaneous move game:
supplier privately chooses high or low effort (e=h or e=l) at cost c(e)
monitor privately chooses to monitor at cost k or not
5. Monitor publicly reports },,{ lhr and contractual transfers are made
6. Seller sets the final good price p
7. Buyers get pev )( if they purchase
8. Quality },{ lhq is publicly observed if buyers purchased
Trade repeatedly with discount factor )1,0(
8. Institutional choice
Compare performance (social surplus) in two regimes:
- second-party monitoring (seller inspects)
- third-party monitoring (independent party inspects)
Incentive compatibility conditions
suppliers are willing to
- randomize between compliance and non-compliance
- participate
monitor is willing to
- inspect
- report truthfully the outcome of inspection
seller is willing to offer contracts to supplier and monitor
buyers are willing to buy
9. Endogenous variables
contracts between the players
z(r,q) – probability that the game continues (reputation is good)
x – probability of compliance with food safety standards
y – probability of inspection
Two types of inefficiency
- costly inspections
- no trade or trade in low quality
happen in equilibrium
10. Second-party monitoring
Inspections are frequent
Compliance frequency is determined by

- no information rent for suppliers maximizes sustainable compliance rate
- social surplus is wasted on monitoring
=> third-party monitoring may improve welfare
- if supplier’s liability is large, infrequent monitoring is optimal and social surplus is not dissipated
