The Impact of Tariff Structure on Customer Retention, Usage, and Profitability of Access Services

Iyengar, R., Jedidi, K., Essegaier, S., & Danaher, P. J. (2011). Marketing Science, 30(5), 820–836.

Marketing Science · 2011DOI: 10.1287/mksc.1110.0655 ↗

Plain-English take

Compared with pay-per-use pricing, the two-part tariff reduced annual retention by an average 10.5% and yearly usage by 38.7%, after controlling for income effects. For your marketing: Evaluate the behavioral effects of access fees separately from per-use prices.

How much weight to give this

3.5/5 Useful evidence with meaningful caveats

The 1–5 evidence-check score is a practical reading aid, not a formal peer review or a probability that a conclusion is true. It combines design strength (2 points), sample reporting (1), comparison/control clarity (1), and how much of the paper could be checked (1). Access affects how confidently this directory can assess a study, not the study's underlying quality. Blinding is reported separately because it is not relevant to every design.

Design · 1.7/2

An experiment is useful for causal evidence, but the accessible profile does not establish random assignment.

Sample · 0.4/1

A usable sample size is not stated in the profile's accessible source.

Comparison · 0.8/1

Experimental comparison is described; randomization or control details need checking in the paper.

Can we check it? · 0.5/1

This profile could be checked against an abstract or metadata, not the full paper.

Double-blind? Blinding is not reported in the source reviewed; that does not establish whether blinding was or was not used.

Research question

What the authors investigated

How do pay-per-use and two-part-tariff pricing affect service retention, usage and profit?

Design

A utility-based model is estimated with data from a pricing field experiment for a new telecommunications access service.

Sample and setting

Customers of one new telecommunications service in a market experiment; the abstract reports model-based average effects across the experimental tariff conditions.

Reported result

What the study found

Compared with pay-per-use pricing, the two-part tariff reduced annual retention by an average 10.5% and yearly usage by 38.7%, after controlling for income effects. Despite these declines, the two-part tariff remained profit-maximizing in the studied setting. Ignoring the tariff-structure effect reduced modeled firm profit by 11%.

This is a paraphrase of the source. Check the original paper for definitions, estimates, statistical uncertainty and analysis details.

Scope and transfer

Limitations to keep in view

A single telecommunications service and historical market experiment. The profitability result depends on the study's demand, cost and pricing assumptions and should not be treated as a SaaS pricing benchmark.

Possible founder application

Evaluate the behavioral effects of access fees separately from per-use prices. A plan can reduce usage and retention yet still improve profit, so test the full customer and margin outcomes.

Evidence access

Publisher abstract

INFORMS publisher abstract; the experiment setting, tariff comparison and reported percentages are stated there.

If only an abstract or metadata was available, the profile is limited to claims supported there. A paper's paywall does not change its evidentiary status, but it limits what we can substantiate from accessible text.
