What Is a Product Worth? Why Context Matters in Price Research

What would you pay for a coffee mug?

Now imagine that the mug is given to you. It belongs to you, but you are offered the opportunity to sell it. What is the lowest price you would accept?

In a well-known behavioural experiment, people who were given a mug demanded substantially more to give it up than others were willing to pay to acquire one. [1]

The mug had not changed. What changed was the position from which it was evaluated.

For a buyer, acquiring the mug represented a potential gain. For an owner, selling it meant giving up something that was already theirs.

This creates an important problem for consumer research: a stated price is not a context-free measure of value. What consumers say something is worth can depend on what they expected it to cost, how the transaction is framed and whether they already feel some sense of ownership.

Understanding these influences can help researchers distinguish between the value of the product itself and the context in which that value is being measured.

From a purely economic perspective, one dollar should have the same value as any other dollar. In practice, people often divide money into different mental categories and apply different rules to each one.

This is known as mental accounting, which describes the cognitive processes people use to organise, evaluate and keep track of their financial activities. [2]

A consumer may be unwilling to exceed their clothing budget despite having money available elsewhere, or find a $100 bonus easier to spend than $100 from their regular salary. The money has the same purchasing power, but it does not necessarily feel interchangeable.

This matters for price research because consumers are not evaluating price against their total financial resources. They are evaluating it within a particular mental and transactional context.

One important part of mental accounting is the distinction between acquisition utility and transaction utility. [3]

Acquisition utility is the value a consumer expects to receive from a product relative to what they must give up to acquire it. [3]

Suppose a pair of shoes costs $150. A consumer may consider the comfort, quality, appearance and usefulness of the shoes, then compare those benefits with the cost.

In simple terms, acquisition utility asks: Is this product worth what I have to pay for it?

This is often what researchers intend to measure when they ask about willingness to pay. But it is not necessarily the only thing influencing the answer.

Transaction utility refers to the pleasure or displeasure associated with the deal itself. [3]

It depends on how the actual price compares with the consumer’s reference price, meaning the price they expected or considered reasonable.

If the shoes cost $150 but the consumer expected to pay $200, the transaction may feel like a gain. If they expected to pay $120, the same $150 price may feel like a loss.

The product and price remain the same. What changes is the comparison.

In simple terms, transaction utility asks: Am I getting a good deal?

Consumers can therefore value a product without valuing the transaction. Someone may think the shoes are attractive and well made but still consider $150 too expensive. Conversely, an attractive discount can make the transaction appealing even when the product’s desirability alone would not justify the purchase.

Research should therefore distinguish between the value of the product and the value of the deal.

A reference price gives the actual price something to be compared with. It may come from a previous purchase, a competitor’s price, a recommended retail price, a promotional “was” price or expectations about what products in the category normally cost.

Importantly, research itself can also create a reference point. The first price shown, the order of questions or prices presented earlier in a study can all provide a comparison.

Consider a product priced at $80. If a consumer expected it to cost $100, paying $80 may feel like a $20 saving. If they expected it to cost $60, the same $80 price may feel $20 too expensive.

The objective price is identical in both cases, but its psychological meaning is different.

This connects with reference dependence, one of the central ideas within prospect theory.

Reference dependence is a key principle of prospect theory. Rather than evaluating an outcome only according to their final position, people evaluate it relative to a reference point. Outcomes above the reference point are experienced as gains, while outcomes below it are experienced as losses. [4]

That reference point might be what a consumer already has, what they expected to receive, what they previously paid, what they believe other people pay or a goal they are trying to reach.

The same outcome can therefore feel positive or negative depending on the consumer’s starting point.

Prospect theory also includes diminishing sensitivity: sensitivity to a change tends to decrease as an outcome moves further from the reference point. [4] For example, a $20 saving may feel substantial on a $50 purchase but relatively minor on a $2,000 purchase.

For straightforward price decisions, reference dependence and loss aversion are particularly relevant.

Loss aversion refers to the tendency for a loss to have a greater psychological impact than an equivalent gain. [4]

For example, losing $20 may feel more significant than gaining $20. The exact size of this difference is not fixed. It varies across consumers, decisions and contexts.

Loss aversion helps explain why the way an offer is framed can affect behaviour. Consider two financially equivalent messages: “Receive a $20 discount when you buy today” and “Buy today before your $20 discount expires.”

The first presents the $20 as a gain to obtain. The second presents it as something the consumer risks losing. The financial outcome is the same, but the psychological framing is not.

A loss frame will not always be more effective. Its influence depends on whether consumers notice it, believe it and accept the suggested reference point. Researchers should therefore test framing effects rather than assume that a loss frame will perform better.

The endowment effect is the tendency for people to value an item more highly when they own it than when they do not. [1]

The mug example demonstrates this through the difference between willingness to pay and willingness to accept.

Willingness to pay asks how much a person would give up to acquire a product. Willingness to accept asks how much that person would need to receive to give up a product they already own.

These measures may produce different answers because they begin from different reference points.

For the buyer, the product is a possible gain. For the owner, giving up the product may be experienced as a loss. Because losses can carry greater weight than gains, the owner may demand more to surrender the item than the buyer is willing to pay to acquire it. [5]

Loss aversion is an important traditional explanation for the endowment effect, but the two concepts are not interchangeable.

More recent research suggests that other processes may also contribute. Ownership can influence which information is most accessible during valuation, while emotional attachment and associations between an object and the self may also affect value. [6][7]

The endowment effect is therefore best understood as a pattern in which ownership changes valuation, with loss aversion, attention and attachment all potentially contributing.

A consumer does not always need to legally own a product to begin feeling that it is theirs.

Research has shown that simply touching an object can increase perceived ownership. The effect can also occur when people vividly imagine touching it. Perceived ownership may then influence how the object is valued, although the nature of the experience also matters. [8][9]

This can shift the position from which the consumer evaluates the decision. Choosing not to purchase may begin to feel less like declining a potential gain and more like giving up something they already feel connected to.

This has important implications for research. A participant who handles or experiences a product before pricing it may evaluate it differently from someone who has only seen a description.

Neither response is necessarily more accurate. They simply answer different questions.

If the research question is how consumers value a product when first encountering it, allowing them to experience it before asking about price may change what is being measured. If the goal is to understand valuation after product experience, that same interaction may be entirely appropriate.

Together, the concepts described above show why a stated price is not a context-free measure of value.

A high willingness to pay may reflect strong product appeal. But it may also reflect a favourable comparison price, a compelling discount, a gain or loss frame, or a sense of ownership created during the research process.

The number alone cannot tell you which.

Good research design therefore needs to consider not only what participants are asked, but also the context created before they answer.

1. What reference price was used or implied? Ask what participants are likely to be comparing the price against. Did they see a recommended retail price or competitor price? Are they familiar with the category? Did the order of the questions expose them to an anchor? What did they expect the product to cost before the price was shown?

If the reference point is unknown, it becomes difficult to tell whether a response reflects the value of the product or a reaction to the comparison.

2. How was the outcome framed? Consider whether participants are evaluating a benefit to gain, a cost to avoid or something they may have to give up. A willingness-to-pay question and a willingness-to-accept question are not interchangeable.

Discounts, fees and product benefits can also be framed in different ways. Even when two offers are financially equivalent, the gain or loss frame may influence how they are evaluated.

3. What had participants experienced before they valued the product? Consider whether participants handled or otherwise experienced the product before providing a valuation.

These experiences may create psychological ownership and shift the participant’s reference point. Responses from participants who feel like owners may not be directly comparable with responses from participants who are still evaluating the product as prospective buyers.

Rather than allowing these influences to remain hidden, researchers can manipulate them experimentally.

A study could vary the reference price by showing no comparison price, a lower comparison price or a higher comparison price. It could vary the frame by presenting an outcome as a gain to obtain or a loss to avoid. And it could vary ownership by comparing a product description with physical contact or another experience designed to encourage psychological ownership.

Researchers could then compare effects on willingness to pay or accept, purchase intention and product choice, alongside diagnostic measures such as perceived product value, price fairness and deal attractiveness.

These measures should remain distinct. Asking separately about product appeal, value for money and deal attractiveness can help reveal why a particular price produces a particular response.

Where appropriate, behavioural measures such as actual choices, trades, switching behaviour and product retention can provide complementary evidence about how these contextual factors affect decisions.

Consumer decisions are shaped by more than what people can report directly.

Context, comparison points and framing can influence the decision process itself. Strong research therefore needs to consider how the study environment shapes responses and, where appropriate, combine direct questions with behavioural measures that provide another view of consumer response.

The mug experiment illustrates something broader than an ownership effect: consumer value depends partly on the position from which a product is evaluated.

Consumers consider what a product gives them, what they must give up, whether the price feels fair, how the offer compares with their expectations and whether walking away feels like missing a gain or accepting a loss.

Good price research therefore does more than ask, “What would you pay?”

It considers the reference point behind the answer, distinguishes product value from deal value, examines how the outcome has been framed and accounts for any sense of ownership created before the response.

A price is never presented in a psychological vacuum. To understand what consumers value, we also need to understand the context from which they are valuing it.
