SSNIP Test under Competition Act

In competition law, defining the relevant market is fundamental to assessing whether a firm holds a dominant position or if a merger or acquisition may harm competition. The Competition Act, 2002 (hereinafter “the Act”) empowers the Competition Commission of India (CCI) to regulate such matters. A key analytical tool employed by competition authorities worldwide, including the CCI, to define the relevant market is the SSNIP Test — the Small but Significant and Non-transitory Increase in Price test.
This test provides a clear economic method to identify which products or services compete with each other. It helps answer the question: Which products or services are close substitutes, such that consumers would switch between them if prices change? Understanding this is essential for fair competition regulation.
Importance of Relevant Market Definition in Competition Law
Before analysing the SSNIP Test itself, it is crucial to understand why defining the relevant market is essential.
- Dominance and Abuse: Under Section 4 of the Act, the abuse of dominant position is prohibited. To decide dominance, the market where the entity operates must be clearly defined.
- Combination Control: Sections 5 and 6 regulate mergers and acquisitions (combinations). The effect of combinations on competition can only be judged if the relevant product and geographic markets are identified.
- Anti-Competitive Agreements: Section 3 targets agreements that cause an appreciable adverse effect on competition within the relevant market.
Hence, the relevant market forms the foundation for analysing dominance, combinations, and agreements.
Conceptual Foundations of the SSNIP Test
The SSNIP Test is grounded in economic principles related to market power and substitutability.
- Perfect Competition vs. Monopoly: The perfect competition model assumes many firms with no ability to influence price, whereas a monopoly controls the market price entirely.
- Market Power: A firm has market power if it can profitably raise prices above competitive levels without losing too many customers.
- Substitutability: The core idea is that if consumers would switch to alternative products or services in response to a price rise, those products belong to the same market.
The SSNIP Test formalises these ideas into a practical tool.
What is the SSNIP Test?
SSNIP stands for Small but Significant and Non-transitory Increase in Price.
- Small: A modest price increase, typically between 5% and 10%.
- Significant: Large enough to impact consumer choices.
- Non-transitory: Lasting over a meaningful period, generally considered about 12 months, giving consumers time to respond.
The test asks: If a hypothetical monopolist controlling a defined set of products increases prices by 5-10% for at least a year, would enough consumers switch away to make the price increase unprofitable?
If yes, the candidate market is too narrow and should be broadened to include substitutes.
How is the SSNIP Test Conducted?
The SSNIP Test follows a stepwise approach:
- Identify a Candidate Market: Begin by defining the narrowest plausible product and geographic market. For example, a specific brand or product variant within a city or region.
- Hypothetical Price Increase: Assume a single seller (the hypothetical monopolist) raises prices by 5-10% for a sustained period.
- Monitor Consumer Response: Analyse whether buyers switch to alternative products or services in response to the price rise.
- Assess Profitability: Determine if the price increase remains profitable after factoring in lost sales to substitutes.
- Broaden Market Definition: If the price increase is unprofitable, expand the market to include the substitutes customers switched to.
- Iterate: Repeat the price increase test with the broader market until a price rise becomes profitable.
- Define the Relevant Market: The smallest group of products or services where a hypothetical monopolist could profitably impose a SSNIP constitutes the relevant market.
Demand-Side and Supply-Side Substitution
In addition to consumer switching behaviour (demand-side), supply-side substitution is also considered:
- Demand-Side Substitution: Whether customers would switch products or services when prices change.
- Supply-Side Substitution: Whether suppliers can switch production or distribution to new products quickly and cost-effectively, limiting price increases.
Both aspects are vital for a comprehensive market definition.
Application of SSNIP Test under the Competition Act
The CCI uses the SSNIP Test extensively in its investigations:
- Merger Reviews: When examining combinations, the CCI defines the relevant product and geographic markets using the SSNIP Test to assess potential competitive harm.
- Abuse of Dominance Investigations: The CCI assesses whether a dominant firm could profitably sustain price increases, confirming market power.
- Anti-Competitive Agreements: Defining the relevant market helps identify if an agreement restricts competition appreciably within that market.
The CCI often starts with a preliminary market definition based on SSNIP and then refines it with economic studies, market data, and stakeholder inputs.
Case Studies Illustrating SSNIP Application
- Telecom Sector Mergers: In telecom mergers, the CCI distinguished between voice calls, SMS, and data services as separate markets using SSNIP, focusing on whether a price rise in one would cause consumers to switch to others.
- Digital Advertising: In the European Commission’s Google Shopping case, the SSNIP Test could not be applied directly on the zero-priced user side but was applied on the advertiser side where prices exist.
Limitations of the SSNIP Test
Despite its wide use, the SSNIP Test has some limitations:
- Zero-Price Markets: Many digital services are offered free to consumers, making price increases impossible. This limits the SSNIP Test’s applicability.
- Quality Differences: Products differing in quality or features may not show consumer switching purely based on price.
- Multi-Sided Platforms: Platforms with two or more user groups require segmented analysis because prices may differ or be zero for one group.
Complementary Tools to SSNIP
To address these limitations, competition authorities consider other tools:
- SSNDQ Test: The Small but Significant Non-transitory Decrease in Quality test simulates gradual quality reductions to identify substitutability.
- SSNIC Test: The Small but Significant Non-transitory Increase in Costs test focuses on cost factors such as data and consumer attention, especially relevant in digital markets.
- Qualitative Factors: Factors like product characteristics, intended use, and consumer and competitor feedback are also important, as noted in the Topps Europe v Commission case.
Conclusion
The SSNIP Test remains a vital tool under the Competition Act to define relevant markets. Its economically rigorous framework helps competition authorities focus on genuine substitutes, preventing arbitrary market definitions.
However, in the modern economy, especially digital markets where zero-price services prevail, SSNIP must be complemented with alternative tests like SSNDQ and SSNIC, alongside qualitative analysis.
