Alternative Views of Consumer Behaviour
- Free markets are built on the assumptions of rational decision making
- In classical economic theory, the word 'rational' means that economic agents are able to consider the outcome of their choices and recognise the net benefits of each one
- Rational agents will select the choice which presents the highest benefits
- Rational agents will select the choice which presents the highest benefits
- In many ways, the assumption of rational decision making is flawed. Consumers are often more influenced by the following than a rational computation of net benefits
- The influence of other people's behaviour
- The importance of habitual behaviour
- Consumer weakness in computation
The Influence of Other People's Behaviour
- Peer pressure often prompts consumers to make purchasing decisions that may go against a computation of net benefits
- Producers influence consumers choices through various forms of advertising, including lifestyle, celebrity endorsement and influencer culture
- This results in emotional decisions and not necessarily rational decisions e.g. consumers purchasing the branded Nurofen when they could purchase the much cheaper (and essentially identical) Ibuprofen
- Producers use advanced behavioural psychology techniques to influence consumer choices e.g. Neuro branding
The Importance of Habitual Behaviour
- Consumers make so many purchasing decisions that they often rely on habits to speed up the process
- Using rule of thumb refers to a short cut that makes a quick estimation of benefits without gathering too much information
- Consumers use information from the past, which may be outdated, as they habitually purchase the same products e.g. visiting the same sections in a supermarket for several years
- Consumer inertia often develops as convenience is prioritised
- Consumers make purchasing decisions that directly harm them and are usually addictive, for e.g. alcohol
- Sellers recognise habitual patterns and exploit them. for example, products placed at the checkout till to benefit from impulse purchasing (chewing gum)
Consumer Weakness at Computation
- The wider the range of choice, the harder it is for a consumer to gather information and compute which one offers the highest net benefits
- Consumers often lack the time or ability to consider the relative prices of different products and sellers will frequently make it difficult for them to do so
- Products the seller wants to sell are often placed at eye level where computation is easy
- Many products that would deliver higher benefits are placed below knee level or high on the shelf where computation is hard
