We all know that the concept of happiness is impossible to quantify or put into numerical terms, but economists will try anyway! Thus, if the consumer ranks two apples higher than one, and three nuts higher than two apples, he must thereby rank three nuts higher than one apple. There several theories that have been developed to try and explain the behavior of a consumer, however they can be categorized in to two:? Discovering what product, service or idea customers want. This means that a consumer can tell exactly how much satisfaction she can derive from consumption of a certain goods. If indifference curve is vertical straight line parallel to the Y-axis c.

Utility functions are also related to risk measures, with the most common example being the entropic risk measure.

The analysis of how consumers make choices can be done using the budget constraint and indifference curves. His desire for ever greater satisfaction drives him up the indifference curve map see Fig. Algebraically, The above property implies the law of equimarginal utility, which states that the marginal utility per rupee spent, is the same for all goods. Income subsidies ease the way to both combinations, and so less is spent by way of income subsidies to secure the same welfare. It clearly defines and communicates expected behaviors and strengthens the connection between high performance and rewards.

Thus money cannot be used as a measuring-rod since its own utility changes. Despite abandoning the thought of quantifiable utility i. This is the first condition for the consumer to be in equilibrium that indifference curve should touch the budget line. Ordinal utility contrasts with theory: the latter assumes that the differences between preferences are also important. An example indifference curve is shown below: Each indifference curve is a set of points, each representing a combination of quantities of two goods or services, all of which combinations the consumer is equally satisfied with. It shows that the consumer spends his entire budget on current consumption. This would be a measurable utility if and only if the test employed for its direct measurement is based on an objective criterion that could let any external observer repeat the results accurately.

There are a number of differences between the methods in which either measure consumption satisfaction. Since the consumer is assumed to be insatiable, he aims to maximize his satisfaction. They both assume that the consumer is rational.
