Influences on marketing: psychological, sociocultural, economic and government factors in customer choice (HSC Business Studies)
“Factors influencing customer choice (psychological, sociocultural, economic, government); consumer laws (deceptive and misleading advertising, price discrimination, implied conditions, warranties); ethical aspects of marketing”
Customer choice is shaped by four groups of factors in the syllabus. Psychological factors are inside the customer (motivation, perception, attitudes, learning, personality). Sociocultural factors come from the people and society around them (family, reference groups and opinion leaders, social class, culture and subculture). Economic factors set what customers can afford (income, interest rates, inflation, employment, confidence). Government factors are laws, taxes and regulations that restrict or encourage purchases. Marketers study these to segment markets and design the marketing mix. Consumer laws and ethics are the other "influences on marketing", covered in depth on the ethical and legal aspects page.

What this dot point is asking
The syllabus heading "influences on marketing" contains three parts: "factors influencing customer choice: psychological, sociocultural, economic, government"; "consumer laws: deceptive and misleading advertising, price discrimination, implied conditions, warranties"; and "ethical: truth, accuracy and good taste in advertising, products that may damage health, engaging in fair competition, sugging". This page focuses on customer choice, with a summary of the law; the law and ethics are developed fully on the companion page.
How customers make buying decisions
Before looking at the factors, it helps to know the process they act on. Most models describe five stages:
- Need recognition: the customer notices a gap between what they have and what they want (hunger, a broken phone, a new job that needs a car).
- Information search: from memory, friends and family, reviews, websites, social media and salespeople.
- Evaluation of alternatives: comparing brands on price, features, quality and reputation.
- Purchase decision: choosing what, where and when to buy; promotions and availability can tip the decision.
- Post-purchase evaluation: satisfaction leads to repeat purchase and recommendations; dissatisfaction leads to complaints, returns and negative reviews (sometimes "cognitive dissonance", doubt about whether the choice was right).
Level of involvement changes how much effort customers put in:
| Type of decision | Features | Examples |
|---|---|---|
| Routine (low involvement) | Frequent, cheap, little thought; habit and brand loyalty | Milk, bread, toothpaste |
| Limited | Occasional; some comparison | A new pair of runners, a restaurant |
| Extensive (high involvement) | Expensive, infrequent, risky; long search and comparison | A car, a laptop, a holiday, a university course |
Marketers use promotions and shelf position to win routine decisions, and detailed information, reviews, demonstrations and personal selling for extensive ones.
Psychological factors
Psychological factors are internal to the customer.
- Motivation: the inner drive that pushes a person to satisfy a need. Maslow's hierarchy (physiological, safety, social, esteem, self-actualisation) is a common framework: a security system appeals to safety needs; a luxury watch to esteem needs.
- Perception: how a person selects, organises and interprets information. Two customers can see the same advertisement differently. Marketers manage perception through branding, packaging, price (a high price can signal quality) and store design.
- Attitudes and beliefs: lasting feelings and opinions about a brand or product, often hard to change once formed. A business whose reputation has been damaged must work to rebuild positive attitudes.
- Learning: changes in behaviour from experience. A good experience reinforces the purchase (brand loyalty); a bad one discourages it.
- Personality and self-image: customers buy brands that match how they see themselves, for example adventurous, practical or sophisticated.
Marketing response. Emotional advertising, brand building, loyalty programs (which reward and reinforce learning), and product design aimed at the target market's motivations.
Sociocultural factors
Sociocultural factors are external: the influence of other people and society.
- Family: parents, partners and children influence many purchases (groceries, cars, holidays); "pester power" is the influence of children on parents.
- Reference groups and opinion leaders: groups a person belongs to or aspires to (friends, sporting teams, online communities), and individuals whose views others follow (experts, celebrities, influencers). This is why businesses use endorsements and influencer marketing (see the communication process on promotion and place).
- Social class: groupings based on income, occupation and education that share consumption patterns.
- Culture and subculture: the values, beliefs and customs of a society, and of groups within it (based on ethnicity, religion, age or region). Australia's cultural diversity creates demand for different foods, festivals and languages in marketing.
- Social trends: changing values such as health and wellbeing, sustainability, convenience and online shopping.
Marketing response. Segmenting by lifestyle and culture, choosing opinion leaders who match the target market, and adapting products and messages to cultural occasions.
Economic factors
Economic factors determine customers' ability and willingness to spend.
| Factor | Effect on customer choice |
|---|---|
| Income and disposable income | Higher disposable income increases spending, especially on discretionary and luxury items |
| Interest rates | Higher rates raise loan repayments and reduce disposable income for borrowers; they also make saving more attractive |
| Inflation | Rising prices reduce purchasing power; customers trade down to cheaper brands and compare prices more |
| Employment and confidence | Secure jobs and optimism encourage spending; uncertainty encourages saving |
| Economic cycle | In a boom, demand for luxury and durable goods rises; in a downturn, value products do better |
Current conditions (September 2026).
- Interest rates. The Reserve Bank's Monetary Policy Board raised the cash rate target three times earlier in 2026 and held it at 4.35 per cent on 11 August 2026, saying inflation was still too high.
- Inflation. The ABS reported that the Consumer Price Index rose 3.5 per cent in the 12 months to July 2026, down from 3.8 per cent in the year to June, with trimmed mean inflation at 3.6 per cent.
For households with mortgages, three rate rises in a year significantly increase repayments, so marketers of discretionary goods expect customers to delay purchases, trade down and respond strongly to value messages, promotions and flexible payment options. Businesses selling essentials may see customers switch to private-label and bulk buys.
Government factors
Governments influence customer choice by what they allow, restrict, tax and require.
- Restrictions on products and promotion. Tobacco must be sold in plain packaging and cannot be advertised. From 10 December 2025, age-restricted social media platforms (including Facebook, Instagram, Snapchat, TikTok, X and YouTube) must take reasonable steps to prevent Australians under 16 from having accounts, which reduces marketers' reach to younger teenagers on those platforms.
- Taxes and subsidies. GST, excise on alcohol, tobacco and fuel, and subsidies (for example on medicines listed on the Pharmaceutical Benefits Scheme) change the prices customers face and therefore their choices.
- Consumer protection. The Australian Consumer Law gives customers rights and confidence to buy (see below).
- Government spending and transfers. Changes to welfare payments, tax cuts and rebates change disposable income.
Consumer laws (summary)
The Australian Consumer Law (ACL), Schedule 2 of the Competition and Consumer Act 2010 (Cth), is enforced by the ACCC and state and territory fair trading agencies. The syllabus names four areas:
| Syllabus term | What the ACL says | Key point for marketers |
|---|---|---|
| Deceptive and misleading advertising | Section 18 bans misleading or deceptive conduct; section 29 bans specific false or misleading representations, including about price | Every claim, "was" price and comparison must be true and not create a false impression |
| Price discrimination | Charging different prices to different customers is not banned in itself, but can breach the law if it is unconscionable or substantially lessens competition | Student, seniors and off-peak prices are lawful; exploiting vulnerable customers is not |
| Implied conditions | Consumer guarantees: goods must be of acceptable quality, fit for purpose and match their description | Cannot be excluded; a major failure entitles the customer to a refund or replacement |
| Warranties | Warranties against defects are extra promises and must include mandatory text about the consumer guarantees | A warranty adds to, never replaces, the consumer guarantees |
Current case: ACCC v Coles ("Down Down"). On 14 May 2026 the Federal Court found that Coles contravened sections 18(1) and 29(1)(i) of the ACL with misleading "Down Down" price tickets. The ACCC had alleged that between February 2022 and May 2023 Coles temporarily raised the prices of 245 products before putting them on "Down Down" promotions with a "was" price reflecting the higher price. The court found that 13 of 14 sample tickets conveyed false or misleading discount representations because the "was" price had not applied for a reasonable period. Penalties were still to be decided. The case shows how economic conditions (price-sensitive shoppers), consumer psychology (the pull of a "discount") and the law interact.
The full detail, with more cases and the ethical aspects of marketing, is on ethical and legal aspects of marketing.
Scenario. A 17-year-old is choosing a first car.
- Psychological: motivated by independence and safety; perceives some brands as more reliable from past family experience (learning).
- Sociocultural: parents influence the decision (and may pay); friends' opinions and online reviews shape the shortlist; social trends favour fuel-efficient or hybrid cars.
- Economic: a limited budget; higher interest rates in 2026 raise the cost of car loans, pushing the choice towards a cheaper used car.
- Government: licensing rules for provisional drivers, registration and insurance costs, and safety ratings shape which cars are suitable.
Marketing implication. A used-car dealer targeting this segment would emphasise safety ratings (to parents and the buyer), low running costs, finance options and trustworthy reviews.
"Economic factors include interest rates" earns little. Explain the chain: higher rates raise repayments, which reduce disposable income, which reduces discretionary spending, so the business adjusts its marketing mix.
Quote the current cash rate and inflation rate with a date, or explain the mechanism without numbers. Rates in 2026 are higher than in 2025, so old examples about rate cuts no longer describe the situation.
It is lawful unless it is unconscionable or anti-competitive. Many businesses lawfully charge different prices to students, seniors or off-peak customers.
Psychological factors are inside the person (motivation, perception); sociocultural factors come from other people and society (family, peers, culture).

Psychological factors are the internal influences on a customer: motivation, perception, attitudes, learning and personality. Motivation explains why a customer buys: a customer motivated by status (esteem needs in Maslow's hierarchy) may choose a premium phone over a cheaper one with similar features. Perception is how the customer interprets information, so the same discount may be seen as good value by one shopper and as a sign of low quality by another. Attitudes formed by past experience (learning) make customers loyal to, or avoid, a brand.
Sociocultural factors are the influences of the people and society around the customer: family, reference groups and opinion leaders, social class, culture and subculture. Families shape many purchases, such as the weekly grocery shop or a car. Reference groups and influencers affect clothing, cosmetics and entertainment choices, which is why businesses pay creators to promote products. Culture affects demand for particular foods, celebrations and gift purchases, so supermarkets extend ranges for events such as Lunar New Year and Diwali.
Marketers use these factors to segment markets and design products, messages and channels that match what motivates their target market and who influences it.

Marks guide (Original, modelled on NESA criteria). 4 marks: explains how at least two economic factors affect buying decisions, with cause and effect, using accurate current conditions. 2-3 marks: describes economic factors with some link to choice. 1 mark: some relevant information.
Model answer. Economic factors affect how much customers can spend and what they choose. Interest rates: the Reserve Bank raised the cash rate three times earlier in 2026 and held it at 4.35 per cent on 11 August 2026. Higher mortgage and credit repayments reduce the disposable income of households with loans, so they delay discretionary purchases such as cars, holidays and renovations and shift towards cheaper brands. Inflation: consumer prices rose 3.5 per cent in the 12 months to July 2026 (ABS). When prices rise faster than incomes, customers become more price sensitive, compare prices more and buy more private-label products. Income and employment: rising wages and secure employment increase confidence to spend, while fear of unemployment encourages saving. Marketers respond with value messaging, smaller pack sizes, payment options and promotions.

Marks guide (Original, modelled on NESA criteria). 3 marks: outlines how government influences customer choice with a relevant, accurate example. 2 marks: describes government influence. 1 mark: some relevant information.
Model answer. Governments influence customer choice through laws that restrict what can be sold or advertised and to whom, through taxes that change prices, and through consumer protection that affects how businesses market products. For example, from 10 December 2025 age-restricted social media platforms such as TikTok, Instagram and Snapchat must take reasonable steps to stop Australians under 16 from having accounts. This limits the channels businesses can use to reach younger teenagers and changes the marketing mix for products aimed at them. Other examples include plain packaging and taxes on tobacco, which reduce its appeal and raise its price.
