Critically discuss the claim that the concept of rationality offers only a partial account of economic behaviour.

The concept of rationality is part of a broader concept of consumer culture, which spring from the liberalist school of thought. In this essay therefore, we will be discussing the claims of not only the rational model, but of much of liberalist thought as well. As we go along, we will be discussing weather the concept of rationality offers a good account of economic behaviour or not. We will be looking at some of the problems that the concept of rationality has managed to overcome, and how both the rational model and liberalist thought in general are useful tools in theorizing and in allocating resources in the market. At the same time, we will also be looking at the criticisms that can be made on the concept of. It’s major criticisms may be said to be that it tends to avoid taking any form of action (weather abstract or real) on the expansion of its own ideas to the social, and is incapable of giving any moral collective values. Therefore leaving the individual as ‘dope’.

According to liberalism, the consumer is an individual, which rationally pursues his self-defined interests through the market. The individual acts ‘rationally’ by “maximising satisfaction and preferences (or utility) subject to the constraints faced” and minimising the costs and losses. Therefore, liberalism theorises how consumers pursue what they want, not what they want or why they want it. Liberalists separate between what they call formal rationality and substantive rationality. Formal rationality is concerned solely with what consumers want; substantive rationality deals with the values and reasons related to the consumer- in consumer culture, this is called ‘cultural thinking’. In here lies our first problem; by restricting themselves to analysing only the formal, calculating rationality, liberal economics can refrain from making any judgements about the substantive needs and desires of individuals. Therefore, liberals can only ask the question of how individuals ‘calculate’ what they want. If liberals defined ‘what people want’ instead of ‘how do they calculate it’ they would be going against their very own principle of privacy and individual interests.

Although liberalist thought is capable of depicting the economic study of ‘rational action’, it is incapable of studying those needs that led to ‘rational action’. It is then quite ironical to see that although liberalism places individual choice at the centre of its moral and social world, it is something it knows almost nothing about.

Therefore, all our wants and desires are formulated prior to entering the market. The individual forms his desires and wants outside the market- in the private sphere. This idea has managed to ensure the privacy of individuals is safeguarded and has made of it a source of trying to discipline the power of social institutions. This means that by making personal liberty its fundamental goal and by preserving the ‘private sphere’ of the individual, personal interests become the only source of legitimacy. In this way, liberalists bring the image of the consumer as a hero in so far as he is a rational, self-interested economic man. For that reason, the individual becomes sovereign and social institutions have a right in so far as they represent the individuals’ needs, when this fails to be the case, the institution should be dismantled. Unfortunately, these are things easier said than done.

Liberals move from the formulation of desires in the private sphere, to the rational action pursued in the market by defining utility as the “property in an object whereby it tends to produce benefit, advantage…” Therefore, we are able to find out what consumers want by looking at utility in terms of what ‘satisfies them the most’. This idea is extremely successful in meeting consumers’ demand and in coordinating the economy, but at the same time it poses an incredible number of problems. It may be said that liberal thought only looks at the market, and thereby avoids looking at ...
