Register Demand Much of the preceeding material in the consumer theory section is focused on the relationship between a consumer's preferences and a utility function that represents these preferences. There are two reasons for this emphasis.
Preferences are a natural psychological concept. Faced with choice alternatives, it is reasonable to expect that a consumer will be able to rank the alternatives. But when economists evaluate markets, they would like to have a representation of demand. If preferences are represented by a utility function, then demand can be derived from maximization of utility for various prices and income.
In this section, we assume that the consumer has preferences that are represented by a utility function, and we then carry out this derivation of demand. Once demand is represented by a function, it can be used to develop a model of exchange, and it can be combined with the supply functions of firms to model trade in a market.
Utility functions There are several classes of utility functions that are frequently used to generate demand functions. Each of these utility functions has specific properties and uses which are discussed below after the demand function for each is derived.
Diminishing Marginal Rate of Substitution Each of the utility functions examined below exhibits a property called "diminishing marginal rate of substitution. Figure 10 below demonstrates this idea. The curve in the figure shows a many combinations of commodities X and Y that all result in the same utility.
Combinations of X and Y that produce the same utility level are called an "indifference curve. The marginal rate of substitution MRS going from x1, y1 to x2, y2 is 3, since the consumer is willing to give up 3 units of Y to get one additional unit of X. The MRS going from x2, y2 to x3, y3 is only 1.
This reduction in the marginal rate of substitution is one of the main assumptions about preferences or utility beyond the regularity assumptions that were described in earlier sections.
Diminishing MRS is both an intuitive condition on preferences, and also a mild assumption, but in almost all cases it is enough to guarantee that the demand for a commodity decreases as its price increases.
The optimal consumption level for each commodity is determined by setting the slope of the indifference curve through a point x, y equal to the slope of the budget line. Figure 11 shows two consumption points, 'a' and 'b'.

At consumption point 'a', the slope of the indifference curve is not equal to the slope of the budget line. Note that at point 'b', the slope of the indifference curve and the budget line are equal, and the utility level is higher than at point 'a'.
Non-optimal consumption point a and optimal point b.cluster analysis and a median split technique were used to identify market segments based on consumer preferences, behavior, and lifestyles.
Differences between the segments were analyzed. Consumer can choose them by their preference and demand of notebook. An increase in demand for notebooks decline the quantity of demanded, but quantity supply constant.
Everyone also have their desire to buy the more better notebook that have new function. Trusted provider of global economic analysis, data, forecasts, scenarios, models and advisory services.
1 Abstract This study employs a choice experiment approach to investigate consumers’ preferences and willingness-to-pay (WTP) for organic food products. Consumer preferences is the cornerstone of microeconomic theory.
For example, economic theorist can assume that a certain person has Cobb-Douglas preferences for corn and potato. If coefficients are equal, then at equal prices for both goods consumer will choose equal volumes for both.
