Author’s Name: Due Date: Economic Theory of Demand and Supply Microeconomics generally deals with how the society allocates its resources in the most efficient way possible to alleviate human suffering. Through Adam Smith’s theory of the invisible hand, individuals in pursuit of own self-interests generates unintended demand that compel another bunch of individuals to react (supply the needs of the other side) with the expectation of being able to receive a (quantifiable/measurable) compensation package that leaves both sides better off…

Thus, for the exchange of interests (expressed in terms of goods and services) to occur, demand and supply has to exist, but at some costs. From the field of academia to industrial circles, the basic premises of supply and demand are integrated into the daily actions of the society. To be sure, the theoretical mastery of economics depends much on the understanding of the theory at hand (Gandolfi, Gandolfi, and Barash 5-6). The theory of demand and supply is, therefore, an organization principle that coordinates the production of goods and services (in quantities, often referred to as output) to satisfy societal needs through the market (price) mechanism. Intuitively, the price mechanism functions in a perfectly competitive environment to maintain equilibrium of compensation to goods and services delivered by suppliers (supply side) and paid for by the consumers (demand side). The theory of demand and supply applies best to a theoretically free market structure in which no group of buyers or sellers holds the power to set market prices. Accordingly, the theory has two sides: the demand side and the supply side, which both function in the interest of the social needs. For a given commodity delivered in the market for exchange, demand measures the quantity that buyers would be willing and able to acquire at a unit price (Gandolfi, Gandolfi and Barash 17). According to the theory, all consumers are rational decision makers who seek to maximize their utility by choosing the "best" bundle (in terms of quantity) of goods that their money (income) can buy (Silberberg and Suen 252–254). Noteworthy, the two units of measurements in the theory of demand are inversely related; a relationship that sums up the law of demand. That is, ceteris paribus, any increase in the price of a commodity in a purely competitive market environment lowers the number of people (buyers) willing to buy the product. Higher product prices in this case may cause a massive shift by consumers towards more relatively cheaper substitute commodities; a scenario summarized in economics as price substitution effect. Conversely, consumers’ purchasing power acquired through a reduction in the price of a commodity offered for sale in the market increases their ability to buy the product with a possible consequential effect of a massive shift from other commodities considered expensive (income effect). It is important to note that the changes in product prices as well as the quantities along the demand curve occur with all other determinants predominantly held constant (constrained utility maximization) (Samuelson 79). That is, there are many other factors such as income, tastes and preferences, prices of substitute goods among others that occasionally come into play to affect demand of a given product or service. A change in the amount of income, for instance, shifts the demand curve either to the left or right depending on whether the change in income is negative or positive respectively. A sample shift in demand curve due to a decrease in income is shown in the diagram below. Supply on the other hand measures the quantity of commodities made available for exchange at a unit price in the market by sellers (Gandolfi,

There are four primary laws of supply and demand. First, if demand rises and supply remains unaffected, there will be a shortage causing a higher equilibrium cost. Second, if demand lessens and supply remains unaffected, there will be a surplus causing a lower equilibrium cost.
On the other had human beings have unlimited wants. In a free market economy, the forces of demand and supply determine the market equilibrium and the prices are determined by the price system. When a country or a company has a comparative advantage compared to the other countries, producing a same good, the country which has the advantage can supply the good at a cheaper rate compared to the other countries.
The core intentions of any business venture are to supply the market with goods and services in the right quantities of demand;maximize profit and explore measures to necessitate growth and expansion.The process of growth and expansion is purely determined by the business’ performance over a given period of time;its ability to handle micro economic environment and match them with the macro economic factors,and the overall behavior and response of the market.Market forces on the other hand determine the quantity to be produced and supplied by manufacturers and retailers respectively,and depending with the industry that the firm is in, the overall business environment can be explicitly define
Marshall's theory of demand and consumer surplus is to be understood within this context, as are criticisms, or critiques, of it. To understand Marshall's conceptualization of the demand curve and consumer surplus, it is necessary to understand his theory of supply and demand and his classification of markets.
Utility is defined as the amount of satisfaction a consumer derives from consuming a unit of a good or service, in the study of utility is measured in two ways namely cardinal utility and ordinal utility, cardinal utility involves assigning utils which is a measure of the level of utility, for example, the utility derived from consuming a unit of good X is 4 utils and utility derived from consuming good Y is 5 utils.
These are prices, speculation, government policies, tastes and preferences, and changes in income.
Supply and demand in economics are two concepts, which carry a lot of significance as they determine the
g to Taylor and Weerapana (53), the term demand is a relationship between two economic variables namely: the price of a particular good; and the quantity of that good that consumers are willing to buy at the price during a specific time period. It describes how much of a good
