Can Price Still Be an Honest Signal of Products’ Quality? – A Perspective of Blockchain Adoption

·

In today’s consumer-driven market, the promise of “high quality at a fair price” is more than just a marketing slogan—it’s a benchmark for trust and transparency. Yet, in the agricultural supply chain, this ideal is frequently undermined by deceptive practices. High prices no longer reliably indicate superior quality, and consumers are often left guessing about what they’re truly buying. This erosion of trust stems from information asymmetry, where sellers know more about product quality than buyers. But emerging technologies like blockchain are poised to restore integrity to price signals by ensuring authentic, tamper-proof quality disclosure.

This article explores how blockchain technology reshapes the relationship between price and quality in agricultural supply chains. We examine whether price can regain its role as an honest signal and how stakeholders—from farmers to supermarkets—can strategically adopt blockchain to improve transparency, profitability, and consumer confidence.

The Broken Promise of Price Signals

Traditionally, economic theory holds that price reflects value. In a transparent market, high-quality products command higher prices, while lower-quality goods are priced accordingly. However, in practice—especially with credence goods like organic produce or specialty grains—consumers cannot verify quality before or even after purchase.

Cases of fraud abound:

These examples reveal a systemic failure: price no longer reliably signals quality. When dishonest producers exploit information gaps, genuine high-quality producers suffer. Consumers either pay too much for subpar goods or avoid premium products altogether, fearing deception—a phenomenon known as adverse selection.

Blockchain: A New Era of Transparency

Blockchain technology offers a powerful antidote to information asymmetry. By creating immutable, traceable records for each product—from seed to shelf—it ensures that quality claims are verifiable. Every transaction, inspection, and certification is logged on a decentralized ledger accessible to all stakeholders.

In agriculture, this means:

For example, blockchain is already being used in wine supply chains to prevent counterfeiting. The same principles apply to organic produce, fair-trade goods, and other premium agricultural products.

When quality information is on-chain, it becomes impossible for low-quality producers to falsely inflate prices. The market can once again distinguish between genuine and misleading claims—re-establishing price as a credible signal.

Strategic Behavior in the Supply Chain

Our analysis focuses on a two-tier agricultural supply chain: two types of farmers (high-quality and low-quality) and an agricultural supermarket. The supermarket decides whether to adopt blockchain; farmers decide how to disclose quality.

Without Blockchain: The Signaling Game

In the absence of blockchain, farmers rely on price as a signal of quality. Two equilibria emerge:

  1. Separating Equilibrium: High-quality farmers set higher prices; low-quality ones price lower. Consumers learn to associate price with quality.
  2. Pooling Equilibrium: Both types charge similar prices, obscuring true quality.

Our findings show that authentic disclosure through pricing is optimal for farmers when blockchain is not used. However, this system is fragile—easily disrupted by fraud.

Factors Influencing Blockchain Adoption

Several key variables determine whether blockchain adoption makes sense:

1. Planting Cost

Lower planting costs make blockchain more attractive to supermarkets. When production is efficient, the marginal benefit of traceability (e.g., brand premium, consumer trust) outweighs implementation costs.

2. Consumer Sensitivity

As the proportion of information-sensitive consumers grows—those who actively check product origins and certifications—the value of blockchain increases. When enough consumers demand transparency, the entire supply chain moves toward Pareto optimality: everyone benefits.

3. Traceability Accuracy

The number of data blocks recorded affects traceability precision. More granular data (e.g., soil testing, pesticide use) enhances credibility but increases operational costs. Supermarkets must balance accuracy with cost-efficiency.

Frequently Asked Questions (FAQ)

Q: Can blockchain completely eliminate food fraud?
A: While blockchain drastically reduces fraud by making data tamper-proof, its effectiveness depends on accurate initial data entry. If false information is uploaded at the source, the chain remains “true” but misleading. Therefore, blockchain works best alongside strong verification protocols.

Q: Do all farmers benefit from blockchain adoption?
A: Not necessarily. High-quality farmers gain credibility but may face tighter price competition. Low-cost producers benefit most when consumers reward verified quality with premium purchases.

Q: Is blockchain adoption cost-effective for small farms?
A: Currently, setup and maintenance costs can be barriers. However, shared platforms and government subsidies are making blockchain more accessible. As tech matures, economies of scale will likely improve affordability.

Q: How does blockchain affect pricing strategies?
A: It shifts pricing from signaling to justification. Instead of guessing quality from price, consumers see proof. This encourages fair pricing based on actual inputs and practices.

Q: What role do supermarkets play in blockchain adoption?
A: Supermarkets act as gatekeepers. By choosing to implement blockchain, they drive upstream compliance and shape consumer expectations. Their willingness depends on ROI from enhanced brand trust and reduced recall risks.

Q: Will transparent supply chains become the norm?
A: Trends suggest yes. With rising demand for ethical sourcing and food safety, transparency is evolving from a differentiator to a baseline expectation—accelerated by technologies like blockchain.

Conclusion

The question “Can price still be an honest signal of quality?” has no simple answer—but blockchain brings us closer to a truthful marketplace. By enabling authentic quality information disclosure, it restores the link between value and cost. While challenges remain—such as adoption costs and strategic trade-offs—the long-term trajectory points toward greater transparency, fairness, and efficiency in agricultural supply chains.

For stakeholders, the message is clear: embracing blockchain isn’t just about technology—it’s about rebuilding trust in a world where price alone can no longer tell the whole story.
