ผศ. รังสรรค์ โนชัย ได้อธิบายทฤษฎีอุ

Asst. Prof., wedding, no theoretical explanation if there is demand. Chai Foundation comes from the theory of behavior and consumed. Make the theory itself need to reference definitions, assumptions about consumer behaviour all that khan is the assumption that the consumer must set the consumption of goods and services in order to obtain maximum satisfaction under the terms of the price of goods and services, income, and money.The supplied Consumer satisfaction measuring and comparing the value means the utility check, sort of relationship satisfaction. the main hypothesis of this residential utility. We can customize the format and variable factors influencing the consumption of goods and services is clearly to be used in the analysis. The pattern of demand depends on the format of the given utility to the consumer's satisfaction for the variable factors derived from the method of finding the greatest utility. So the consumption of goods and services that consumers receive the highest satisfaction depends on the price of goods and services and income factors, prices reflect the value of goods and services that consumers will want to use compared to the last unit value added utility of deciding the intake increases by one unit, because the theory of utility property of utility consumer goods to reduce the quantity of fallen little.The increased intake, so when prices rise Consumers also need to reduce the consumption of this product to make up the increased utility for the last unit value higher as compared with the price of goods. Similarly, when prices decreased. Consumers can consume increasing quantities because the price has decreased. The last unit, the utility can be reduced according to the.Based on consumption goods increased by 7. Features adjustable intake based on price, the quantity inverse relationships are in demand, with the price of goods. That is when item prices higher intake is reduced and the opposite when the price drops. This adjustment feature is consistent with the observation of phenomena, the behaviour of the consumer is actually a "rule of demand."According to the understanding of common money income as factors that determine the ability of the consumers that have much? If consumers have high income shall show whether he will be able to use the money for consumer products, not only in quantity. Also includes various types of goods and services even more.

Asst. Prof. Chai explains Knowles creates demand theory that is rooted in the theory of consumer behavior. The theory itself must be made ​​based on assumptions about consumer behavior requirements, all of which is most important. The assumptions that consumer demand for goods and services in order to get maximum satisfaction under revenue and cost of goods and services required to. Consumer satisfaction measurement and comparison of the configuration utility to sort of relationship satisfaction, it was completely the principles of the theory of utility. We can define variables and factors influencing consumption of goods and services clearly to be used in further analysis. Patterns of demand depending on the form of a utility that confirms the satisfaction of consumers for variable factors that have come out of the way for most utilities. The contribution of consumer goods and services that consumers get the most satisfaction depend on the price of goods and services and income factor represents the price of goods and services that consumers need to be comparable with the added utility. The last unit of the product in deciding consumption increased by one unit. The utility theory has the feature set of utility consumption to a diminished volume
increased consumption. So when prices soared. Consumers also need to reduce the consumption of this product down to the last unit of utility increases were higher as compared with the price higher. Similarly, when prices drop. Consumers were able to consume the volume increasing because prices have fallen. Utilities make the final unit can be reduced accordingly. This
is possible by increasing consumption itself. The volume of consumer prices as the supply-demand relationship in the inversely to its price, ie the price higher consumption will be reduced. And conversely, when prices fell. Adaptive manner consistent with the phenomenon of consumer behavior actually observed to be. "The law of demand"
as commonly understood financial income are factors that limit the ability of consumers to consume that much profit. If consumers have a higher income would show that he is able to use the money for consumer goods not only in greater quantities. Also, the type of product and service offerings even more.
