Economics of food certification Diogo Souza Monteiro Kent Business School
Why should we care? Agro-food markets are increasingly differentiated –Quality attributes such as organic or local are used E.g. organic market was worth 13 billion euros (2005) Variety of quality schemes –Private vs Public driven –Some are becoming condition to enter markets EU Agricultural Product Quality Policy –B2B quality assurance schemes (EurepGAP) –B2C quality schemes (PDO/PGI, Organic,Fair trade, etc All these quality schemes require certification
Outline What is certification? Information asymmetries and certification Research questions What was found? What affects the number of certifiers in a market? Certifiers size and quality of certification? Answers thus far… Future research
What is certification? Is the act of verifying whether a standards is met. More formally is the verification of conformity to a standard by an accredited 3rd party (Meuwissen et al 2003) Why is it necessary? To reduce information asymmetries (credence and Potenkim goods) Facilitates trade reducing transaction cost Thus …Quality control and certification underpin all (?) quality assurance schemes
Information asymmetries and certification Search and experience goods (Nelson 1970) Quality claims are easily verified Immediately (eg. variety of apple) Through repeated sales (beef tenderness) First (seller) and second party (buyer) certification is enough Rely on reputation and trust on the product Credence (Darby & Karni 1973) and Potemkin (Tiezle&Weber 1991) –Cannot be verified by buyers –Uncertainty Require 3rd party! Need to rely on certifiers
Research questions Clearly there is a market for certification services… But –How does it work? Is it efficient? –How to evaluate certification services? –What performance/benchmarks should we define?
What was found (1) Tirole (1986) uses a PA model to show how certifiers may collude with one of the other parties to reduce the availability of information. Choi and Scarpa (1994) finds that the size of a auditor may impact the quality of its service. Lizzeri (1999) proposes a game theory model and finds that the more competitive is the auditing market the more information is revealed. Third party certifiers are opportunistic agents and moral hazard may affect quality of certification [Jahn et al (2005); Hatanaka and Busch (2008)]
What was found (2) Albersmeier et al (2009) did an empirical analysis of certifiers in the German meat industry They compared differences in auditing and certification practices There is evidence to question validity and reliability of third party practices, namely: – Inconsistencies in the auditing processes Within and across certifiers –Issues and inefficiencies in certification Auditors may not be as attentive to reduce costs or pay lip service –Economic dependencies and courtesy certification Certifiers seem to be softer on powerful clients…
What affects the number of certifiers in a market? We analyzed competition between EurepGAP certifiers –100 accredited, 28 countries The number of certifiers depends on: –Export orientation –Years of entry –Presence of a multinational certifier
Certifiers size and quality of certification We adapted a Choi and Scarpa (1994) to investigate a monopolistic third party optimal certification effort Findings: –The optimal amount of product certified is indirectly affected by average effort. –There may be restrictions on product certified to collect a rent –However it can also make use of economies of scale to increase overall quality –Given the credence nature of certification a monopolistic TPCs may collect rents
Answers thus far… Certification is costly… but not clear benefits to sellers (Renard 2005) –How should we price certification There are inefficiencies in the market –Structural … certification is a credence good –Operational (see Albersmeier et al)
Future work How can we compare TPC? –Take into account: Differences across standards, Differences across products and pools of producers What performance measure? –Ratio of certified product? –Ratio of subjective vs. objective measures? How to cost/price certification? Should every firm pay the same fee? Does traceability facilitate/hinder costs of certification?
