Nuvana sells wireless headphones online. Some customers saw only the current price, while others first saw a much higher reference price. The products and current price were identical. The higher reference price increased purchases, although rival retailers offered comparable headphones more cheaply. This may indicate anchoring bias.
Consumer groups argue that customers have limited time to compare technical specifications and may follow a rule of thumb such as choosing the middle-priced product. Nuvana responds that customers remain free to compare every alternative.
Nuvana's managers receive bonuses for increasing sales and market share. They intend to use introductory offers to establish the brand, even if current profit falls. Shareholders question whether this objective is consistent with long-run commercial success.
The consumer authority is considering requiring retailers to provide evidence that advertised reference prices were previously charged.
Table 1 is shown below.
Results of the reference-price trial
| Customer group | Website visitors / number | Purchases / number |
|---|---|---|
| No reference price | 400 | 120 |
| High reference price | 400 | 180 |

Bellara Clinics tested two descriptions of the same treatment. One described its success rate; the other described its failure rate. Although the probabilities were equivalent, acceptance differed. Researchers identified framing bias.
Patients often have little time and limited medical knowledge. Lengthy disclosures may therefore add to information overload rather than produce fully informed utility maximization.
The health authority proposes a mandated choice: patients must actively accept or reject treatment after receiving a short standardized explanation. No option is preselected or removed.
Critics argue that some patients prefer doctors to make recommendations. Bellara supports the proposal but is also concerned about administrative costs.
Treatment choices under two equivalent descriptions of the same treatment.
| Treatment frame | Accepted (patients) | Total patients |
|---|---|---|
| Success-rate frame | 350 | 500 |
| Failure-rate frame | 250 | 500 |
Choices and treatment costs in the mandated-choice pilot.
| Treatment option | Patients selecting | Cost per patient / currency units |

Vistara offers a free trial that automatically becomes a paid subscription unless cancelled. Many users report intending to cancel but postponing the task. This may reflect bounded self-control.
Cancellation requires several online steps. Vistara argues that all conditions are disclosed, but consumer groups state that users have bounded rationality and may not read a lengthy contract.
Vistara is rapidly entering foreign markets. Managers currently prioritize growth maximization, measured through subscribers and sales, rather than the greatest attainable short-run profit.
The regulator proposes a reminder 48 hours before payment and a one-click cancellation link. Vistara predicts that this will reduce renewals and increase administration costs.
For Table 1, assume that users were randomly allocated to otherwise comparable groups that differed only in whether they received the reminder. Neither group had the proposed one-click cancellation link.
Renewal outcomes for 1,000 trial users in each group.
| Trial-user group | Trial users | Renewals |
|---|---|---|
| No reminder | 1000 | 700 |
| Reminder | 1000 | 520 |
Table 1: Renewal trial. Users were randomly allocated to otherwise comparable groups; neither group had the proposed one-click cancellation link.
| Group | Users allocated | Users renewed |
|---|---|---|
| No reminder | 1000 | 700 |
| Reminder | 1000 | 520 |

Marindi's education ministry tested cafeteria arrangements. Under unrestricted choice, water and high-sugar drinks were available. Under restricted choice, high-sugar drinks were removed, while water and unsweetened drinks remained.
Supporters argue that restriction reduces harmful impulsive choices and information overload. Opponents state that it limits freedom and ignores differences in preferences.
Freshway operates the cafeterias. It has adopted corporate social responsibility by reducing sugar and packaging waste, even though high-sugar drinks previously produced a higher contribution per unit.
Freshway expects healthier menus to improve its reputation and contract-renewal prospects. The ministry is considering whether a water-at-eye-level nudge would be preferable to restriction.
Drink selections under two cafeteria arrangements.
| Arrangement | Water | Unsweetened drinks | High-sugar drinks | Total pupils |
|---|---|---|---|---|
| Unrestricted choice | 320 | 160 | 320 | 800 |
| Restricted choice | 520 | 280 | 0 | 800 |
Contribution per drink sold by Freshway.
| Drink type | Contribution / currency units per drink |
|---|---|
| Water | 0.40 |
| Unsweetened drink | 0.60 |
| High-sugar drink | 0.90 |

Many Kopa users say they want emergency savings but spend unexpected income immediately. The app tested messages comparing a user's saving with that of similar households. Such messages are a consumer nudge because users remain free to save any amount.
Some users may follow others as a rule of thumb rather than calculate the utility from present and future consumption. Low-income households argue that insufficient income, rather than inattention, limits their saving.
Kopa's managers seek acceptable profit, stable employment and manageable workloads rather than the highest possible profit. Its stated objective is satisficing.
A bank proposes paying Kopa for each user who opens a savings account. Consumer groups fear that the app's choice architecture could then serve the bank rather than users.
Social-comparison trial outcomes for Kopa users.
| User group | Number of users | Users who saved |
|---|---|---|
| No message | 600 | 150 |
| Social-comparison message | 600 | 240 |
Kopa's annual performance against satisficing targets.
| Measure | Satisficing target | Actual annual result |
|---|---|---|
| Profit / currency units | Minimum 400 000 | 420 000 |

Oranta Coffee introduced beans certified as paying farmers higher wages. Some consumers paid more despite saying that taste and quality were unchanged. Researchers suggested bounded selfishness, since fairness and concern for producers affected choice.
Other consumers doubted the certification and lacked information about supply chains. A recent documentary about poor working conditions also increased demand for certified coffee, possibly because of availability bias.
Oranta accepted higher input costs as part of its corporate social responsibility policy. Managers believe customer loyalty will eventually increase profit.
A rival argues that Oranta should pursue profit maximization and use the cheapest legal inputs. Regulators are considering standardized certification labels.
Consumer survey of coffee choices and prices in Oranta.
| Coffee type | Price / currency units | Consumers / number (out of 500) |
|---|---|---|
| Conventional | 5 | 300 |
| Certified | 6 | 200 |
Monthly revenue and total cost by coffee sourcing method in Oranta.
| Sourcing method | Monthly total revenue / currency units | Monthly total cost / currency units |

Aeroza's booking page preselects travel insurance and priority boarding. Customers can remove either item. This is a default choice, and accepting the preset package requires no action.
Many passengers complete bookings quickly on mobile phones. Consumer groups argue that limited attention and complicated wording create bounded rationality. Aeroza says every price is displayed before payment.
Aeroza aims to increase passenger numbers and routes. Managers describe this as growth maximization, even though rapid expansion has increased training and maintenance costs.
The regulator proposes that no add-on be preselected and that passengers make an active choice about insurance.
Table 1: results of the airline insurance add-on trial.
| Booking group | Passengers | Passengers purchasing insurance |
|---|---|---|
| No insurance preselection | 800 | 160 |
| Insurance preselected | 800 | 440 |
Aeroza expansion data for two years.

After intense reporting of a rare side effect, vaccine bookings fell. Officials argued that availability bias caused people to overestimate events that were vivid and easy to recall.
The health ministry introduced a balanced factsheet showing both the probability of protection and the probability of side effects. Some citizens found the statistics difficult to interpret.
Meditex manufactures the vaccine. Managers seek an acceptable return while maintaining spare capacity for emergencies. This reflects satisficing rather than maximizing current profit.
Meditex supports the factsheet but opposes a proposed ban on sensational advertisements by private clinics, arguing that existing consumer information is sufficient.
Vaccine bookings and rates before and after intense reporting.
| Period | Eligible people | Bookings | Booking rate (%) |
|---|---|---|---|
| Before intense reporting | 1000 | 680 | 68 |
| After intense reporting | 1000 | 470 | 47 |
Meditex performance against minimum targets.
| Performance measure | Minimum target / % | Actual / % |

Tavira requires energy labels on refrigerators. Many labels contain numerous technical measures, and shoppers often select the first model meeting an acceptable standard. This is satisficing by consumers under bounded rationality rather than exhaustive utility maximization.
The energy agency tested a simplified label using three colours and an estimate of annual running cost. Prices and appliances were unchanged.
HomeHub places its own high-margin refrigerator in the centre of a three-model display because shoppers frequently use the middle option as a rule of thumb.
The government is considering a standardized display order. HomeHub argues that retailers should retain control of product presentation and that consumers can search online.
Results of the simplified-label trial
| Label type | Shoppers / number | Chose efficient model / number |
|---|---|---|
| Technical label | 600 | 210 |
| Simplified label | 600 | 330 |

Senda Markets marks products approaching their expiry date with a green sticker and places them beside checkout queues. The retailer describes this as a nudge because customers may still buy any product at unchanged prices.
Some customers infer that the green sticker is a recommendation. Others avoid the products because vivid news reports about food poisoning influence perceived risk, despite the products meeting safety standards.
Senda adopted corporate social responsibility targets for food waste and donations. Managers accept sorting costs and lower current revenue from unsold stock.
Shareholders argue that products should instead be priced to maximize profit. Managers claim the policy attracts customers and motivates employees.
Green-sticker trial outcomes by display arrangement.
| Display | Shoppers | Bought near-expiry product |
|---|---|---|
| Usual display | 700 | 140 |
| Green-sticker checkout display | 700 | 245 |

The government of Country A is concerned that many workers intend to save for retirement but postpone joining a pension plan. It introduced automatic enrolment at several large employers. Workers may opt out at any time without charge.
Table 1 compares pension participation before and after automatic enrolment.
Eligible employees and pension participation rates before and after automatic enrolment at three employers in Country A.
| Employer | Eligible employees / workers | Before enrolment / % | After enrolment / % |
|---|---|---|---|
| Alpha | 2000 | 42% | 78% |
| Beta | 1500 | 36% | 72% |
| Gamma | 2500 | 48% | 80% |
Under the scheme, employees contribute 4% of annual salary and employers contribute a further 3%. Table 2 provides information about employees who remained enrolled after the policy was introduced.
Table 2: Employees remaining enrolled after automatic enrolment and pension contribution rates.
| Employer | Employees remaining enrolled / workers | Average annual salary / currency units | Employee contribution rate / % | Employer contribution rate / % |
|---|---|---|---|---|
| Alpha | 1560 | 30000 | 4 | 3 |
| Beta | 1080 | 28000 | 4 | 3 |
| Gamma | 2000 | 32000 | 4 | 3 |
A government survey found that 68% of workers who had not joined a pension stated that the application was too complicated, 47% repeatedly postponed the decision and 39% could not compare the fees charged by different pension providers. Some workers argued that automatic enrolment could cause financial hardship for low-income households.
Define the term bounded self-control.
Using Table 1, calculate the increase in the total number of employees participating in a pension plan following automatic enrolment.
Using Table 2, calculate the total annual value of employee and employer pension contributions after automatic enrolment.
Calculate the percentage of eligible employees who opted out of automatic enrolment across the three employers.
Explain how automatic enrolment may increase pension participation even though workers remain free to opt out.
Distinguish between a mandated choice and a restricted choice in the context of pension saving.
Explain how the survey evidence challenges the assumption of perfect information in rational consumer choice theory.

The health ministry of Country B tested different ways of presenting meals in hospital cafeterias. A healthy meal and a regular meal remained available as alternatives in every trial except under restricted choice. The underlying meals and prices did not change during the experiment.
Table 1 shows the results among equal-sized groups of cafeteria customers.
Meal selections under unrestricted active choice, the healthy default and mandated active choice, plus assigned meal offers under restricted choice, among equal-sized groups of 800 hospital cafeteria customers. Under restricted choice, the 640 and 160 figures are policy-assigned offers, not voluntary selections.
| Choice arrangement | Healthy meal / customers | Regular meal / customers | Total / customers |
|---|---|---|---|
| Unrestricted active choice | 240 | 560 | 800 |
| Healthy default with easy opt-out | 520 | 280 | 800 |
| Mandated active choice | 400 | 400 | 800 |
| Restricted choice: 640 customers offered only healthy meal; 160 offered only regular meal | 640 | 160 | 800 |
Table 2 provides price and cost information for the two meals.
Prices and unit costs for each meal, unchanged across all customer groups.
| Meal | Price / currency units per meal | Unit cost / currency units per meal |
|---|---|---|
| Healthy meal | 8 | 5 |
| Regular meal | 7 | 3 |
Health researchers estimated that the healthy meal generates lower average public healthcare costs and lower greenhouse-gas emissions. Critics argued that the government should not manipulate adults' food choices and that some patients require meals with different nutritional characteristics.
Define the term choice architecture.
Using Table 1, calculate the healthy-meal selection rates under unrestricted active choice and the healthy default, and the percentage-point change between them.
Determine the additional number of healthy meals that would be selected per 2000 customers if the healthy default replaced unrestricted active choice.
Using Tables 1 and 2, calculate the change in cafeteria profit for a group of 800 customers when the healthy default replaces unrestricted active choice.
Explain why the healthy default may change meal selections without changing prices or removing either meal.
Distinguish between the mandated-choice and restricted-choice arrangements used in the experiment.
Explain how bounded selfishness could influence a customer's meal choice.
Using the text/data provided and your knowledge of economics, recommend a choice-architecture policy for meals sold in Country B's public hospitals.

| On-time delivery rate / % | 96 | 90 |
| Worker training spending / currency units | 160000 | 120000 |
Lumina's owners are concerned that current profit has fallen. Worker representatives report that expansion has increased workloads and injuries. The government is considering whether firms bidding for public delivery contracts should be required to meet safety and social-responsibility standards.
Define the term profit maximization.
Using Table 1, calculate Lumina's total profit in Year 1 and Year 2 and the change in profit.
Calculate Lumina's market share in each year and the change in market share in percentage points.
Calculate the percentage growth in Lumina's deliveries and the percentage growth in the total market between Year 1 and Year 2.
Explain why the data suggest that Lumina prioritized market-share or growth maximization rather than short-run profit maximization.
Explain how Lumina's expansion could increase long-run profit despite reducing current profit.

Selva Clothing is choosing between a conventional production plan and a responsible production plan using certified materials, safer working conditions and less polluting technology. Managers estimate the annual outcomes shown in Table 1.
Annual operating data for Selva Clothing's two production plans.
| Production plan | Price / currency units per item | Sales / items per year | Variable cost / currency units per item | Fixed cost / currency units per year | Emissions / kg per item |
|---|---|---|---|---|---|
| Conventional | 50 | 100000 | 28 | 1000000 | 12 |
| Responsible | 50 | 110000 | 34 | 1200000 | 5 |
A consumer survey is summarized in Table 2.
Survey responses from 1000 consumers about responsible clothing production and price.
| Consumer response | Consumers / number | Share of respondents / % |
|---|---|---|
| Prefer verified responsible item at the same price (0% premium) | 440 | 44 |
| Prefer a verified responsible item even when its price is 1% to 5% higher | 260 | 26 |
| Buy the lowest-priced item regardless of certification | 180 | 18 |
| Unsure because sustainability labels are difficult to compare | 120 | 12 |
| Total respondents | 1000 | 100 |
Selva's shareholders are divided. Some want the plan producing the greatest current profit. Others argue that corporate social responsibility could strengthen customer loyalty, reduce regulatory risk and improve long-run performance. The government is considering policies to encourage credible environmental and labour commitments by clothing firms.
Define the term corporate social responsibility.
Using Table 1, calculate Selva's annual profit under each production plan.
Calculate the short-run profit sacrificed if Selva adopts the responsible production plan.
Calculate the change in total annual emissions if Selva adopts the responsible production plan and the percentage reduction relative to conventional production.

Movana Ride reduced fares and paid large joining bonuses to drivers. Its share of urban trips increased. Managers stated that market-share maximization was necessary to build a network before rivals expanded.
Current profit fell, but managers expect a larger user base to create brand recognition and lower average marketing costs. Drivers report longer working hours and reduced support quality.
The app displays the most expensive vehicle category first. This initial fare may create anchoring bias, making the standard fare appear inexpensive.
The transport regulator is considering standardized fare displays and minimum service-quality requirements.

Read the extracts and answer the questions that follow.
Arvena is owned by thousands of shareholders but managed by salaried executives. Managers seek sufficient profit to satisfy shareholders while preserving stable employment and manageable expansion. This is satisficing.
Shareholders argue that managers may prefer larger offices, more staff and lower workloads. Imperfect information makes it difficult for shareholders to determine whether the highest attainable profit has been earned.
Arvena offers a ten-year repair service. Customers cannot easily judge future reliability and therefore face imperfect information. Many buy Arvena after recommendations from friends rather than comparing all producers.
Management proposes investing in repair centres and sustainably sourced timber. The investment would lower current profit but could support loyalty, growth and corporate social responsibility.
Managerial targets and current outcomes at Arvena Furniture.
| Measure | Acceptable target | Actual outcome |
|---|---|---|
| Annual profit / million currency units | Minimum: 6.0 | 6.8 |
| Employee turnover rate / % | Maximum: 12 | 9 |
Annual revenue and total cost under Arvena's two plans.
| Plan | Annual revenue / million currency units | Total cost / million currency units |
|---|---|---|
| Current plan | 40.0 | 33.2 |
| Investment plan | 45.0 | 39.5 |
Define the term satisficing (Text A, paragraph 1).
Define the term imperfect information (Text B, paragraph 1).
Using Table 1, calculate how far each actual outcome was from its acceptable target.
Using Table 2, calculate profit under each plan and the change in forecast profit if Arvena invests.
Using a target diagram, explain why Arvena's current performance is consistent with satisficing (Text A, paragraph 1).
Using a profit-maximization diagram, explain how a shareholder seeking maximum profit would determine Arvena's output.
Using a demand and supply diagram, explain how Arvena's repair service could affect demand for its furniture (Text B, paragraph 1).
Using a schematic total-revenue and total-cost diagram, explain how the proposed investment may affect Arvena's short-run profit (Table 2).
Using information from the texts/data and your knowledge of economics, discuss whether satisficing is a more realistic objective than profit maximization for Arvena.

The consumer protection authority of Country C investigated an online entertainment company. Identical customers were randomly assigned to different presentations of the same monthly subscription. The subscription price and quality were unchanged across the groups.
Table 1 presents the results.
Purchase outcomes for customers shown different price presentations.
| Group | Price presentation | Subscription price / currency units per month | Sample size / customers | Number purchasing / customers |
|---|---|---|---|---|
| 1 | No reference price | 18 | 500 | 110 |
| 2 | High reference price: 30 | 18 | 500 | 185 |
| 3 | Competitor median price: 16 | 18 | 500 | 90 |
Customers shown the high reference price saw the statement “Usually 30 currency units—today only 18”. The service had not been widely sold at 30 currency units. The subscription automatically renewed, and its cancellation instructions occupied four pages. Table 2 contains further financial information.
Monthly subscription pricing, service-cost and refund information.
| Item | Value |
|---|---|
| Subscription price | 18 currency units per subscriber per month |
| Marginal service cost | 6 currency units per subscriber per month |
| Median competitor monthly price | 16 currency units per month |
| Refund rate among high-reference-price purchasers | 12% |
| Refund paid per refunded subscription | 18 currency units |
| Service cost recovered on a refunded subscription | 0 currency units recovered; 6 currency units of service cost still incurred |
The company argued that consumers were free to reject or cancel the subscription. The authority found that many customers mistakenly believed that the displayed reference price represented the typical market price.
Define the term anchoring bias.
Using Table 1, calculate the purchase rates for the no-reference-price and high-reference-price groups, the percentage-point difference and the percentage increase relative to the no-reference-price group.
Calculate the company's monthly total revenue, total variable cost and contribution before fixed costs from purchasers in the high-reference-price group.
Using the expected number of refunds, calculate the company's expected monthly contribution after refunds and before fixed costs from the high-reference-price group.
Explain how the experimental results challenge the assumptions of rational consumer choice.
Explain how a rule of thumb may have influenced customers shown the high reference price.
Explain why providing more cancellation information may not fully protect consumers in this market.
Using the text/data provided and your knowledge of economics, recommend a consumer protection policy for online subscriptions in Country C.
The energy regulator of Country F tested three choice arrangements for households selecting an electricity tariff. The renewable and standard tariffs remained available in all three trials. Table 1 shows the results.
Household tariff selections under three choice arrangements in Country F.
| Choice arrangement | Renewable tariff / households | Standard tariff / households | Total / households |
|---|---|---|---|
| Renewable default | 720 | 280 | 1000 |
| Mandated active choice | 560 | 440 | 1000 |
| Standard default | 280 | 720 | 1000 |
Table 2 provides information about monthly profit contributions and emissions under each tariff.
Monthly information per household for the two electricity tariffs. Profit contribution equals revenue minus cost.
| Tariff | Revenue / currency units/month | Cost / currency units/month | Profit contribution / currency units/month | Emissions / kg/month |
|---|---|---|---|---|
| Renewable | 64 | 52 | 12 | 80 |
| Standard | 60 | 44 | 16 | 300 |
The electricity supplier originally used the standard tariff as the default because it generated greater profit per customer. It is willing to accept a lower but satisfactory profit if this reduces emissions and protects its reputation. Low-income groups have expressed concern that the renewable tariff is more expensive.
Define the term satisficing as a business objective.
Using Table 1, calculate the renewable-tariff selection rate under each arrangement and the difference between the two default arrangements.
Using Tables 1 and 2, calculate the supplier's total monthly profit contribution from each of the three groups.
Using Tables 1 and 2, calculate total monthly emissions for the renewable-default and standard-default groups, and the absolute and percentage reductions produced by changing to the renewable default.
Explain how the results demonstrate the influence of a default choice on consumer behaviour.
Explain why accepting the renewable-default outcome could be consistent with satisficing rather than profit maximization by the supplier.
Using the text/data provided and your knowledge of economics, recommend a choice-architecture policy for household electricity tariffs in Country F.
