Issues facing the demand and supply

Robbins has defined Economics as the science that studies human behavior as relationship between ends and scarce means which have alternative uses". Human wants are virtually unlimited and non-satiable, but the means to satisfy them are limited. Managerial Economics hence has evolved as a discipline of choice making. But why does scarcity arise? A resource is scarce if demand for it exceeds its supply. Scarcity is, therefore, a relative term. Anything that commands a price is a scarce item, called economic good, and the rest are free goods. Any item which is a free good today in a particular society may become an economic good tomorrow. Thus, scarcity can be defined as a condition in which resources are not available in adequate amounts to satisfy all the needs and wants of a specified group of people. The problem of scarcity, and thereby, choice would not have arisen if resources of production had been in abundance. A choice has to be made between ends (unlimited wants) and means (limited resources). Due to scarcity of resources, we have to constantly match the ends and means.

In Managerial Economics we are concerned with demand for a commodity faced by the firm. This depends upon the size of the total market or industry demand for the commodity, which in turn is the sum of the demands for the commodity of the individual consumers in the market. Thus we begin by examining the theory of consumer demand in order to learn about the market demand on which the demand for the product faced by a particular firm depends.

Demand is one of the crucial requirements for the existence of any business enterprise. A firm is interested in its own profit and/or sales, both of which depend partially upon the demand for its product. The decision which management makes with respect to production, advertising, cost allocation, pricing etc. call for an analysis of demand.

Demand for a commodity refers to the quantity of the commodity which an individual household is willing to purchase per unit of time at a particular price. Demand for a commodity implies:

Desire to acquire it,

Willingness to pay for it, and

Ability to pay for it.

Demand has a specific meaning. Mere desire to buy a product is not demand. A miser's desire for and his ability to pay for a car is not demand because he does not have the necessary will to pay for it. Similarly, a poor man's desire for and his willingness to pay for a car is not demand because he lacks the necessary purchasing power. One can also conceive of a person who possesses both the will and purchasing power to pay for a commodity, yet this is not demand for that commodity if he does not have desire to have that commodity.

In keeping with Hicks' insight, we seek here to clarify the implicit assumptions that underlie the shifts in demand and supply curves as they are drawn in existing economics texts. The observons we make are fairly simple, although many teachers of economics may be unfamiliar with them: If the demand relationship is assumed to be 'constant elasticity' (the double logarithm specification), a change in a demand-shifting variable (e.g., income) will result in a rotation of the demand curve and not a parallel shift, while 2) if the demand relationship is assumed to be linear in its arguments, a change in a demand-shifting variable will result in a parallel shift in the demand curve. The clarification is of interest, in part, because virtually all graphs in principles, intermediate microeconomics, and other textbooks in the various field areas are drawn as parallel shifts, implicitly assuming a linear relation. A quick sample of a number of Intermediate Microeconomics texts confirms the potential for confusion [Pindyck and Rubinfeld, 2005; Perloff, 2001 (with the exception of his coverage of an ad valorem tax and a specific tax); Browning and Zupan, 2004; Landsburg, 1999; Salvatore, 1997; Frank, 2000]. Shifting the curves parallel is not, in itself, 'wrong' but rather creates an impression in the student's mind that may lead to later confusion, as for example, when the student thinks in terms of parallel shifts when employing a constant elasticity specification in an econometrics course. Beyond this, those of us who teach regularly are likely to have students ask about why the various shifts 'look' the way they do-Is it always parallel or could it rotate? We suspect that many instructors will find themselves mumbling something like 'anything can happen,' rather than providing the easy response given here. The discussion here appears to 'fall between the cracks' of the standard curriculum in the sense that it is omitted from principles discussions as being (correctly, we feel) too advanced. However, in intermediate courses, supplementing the brief review of supply and demand material with material on the shapes and shifts of demand curves typically does not take place in the rush to get to price consumption paths, extension paths, calculus formalism, and the like. And, by the time future college teachers are in graduate school, the points made here will seem too pedestrian to get into the curriculum, despite the fact that most students are unaware of these observations. We are attempting, not to get these points formally incorporated into existing textbooks, but rather to familiarize those currently teaching economics with the implicit assumptions that underlie the various shifts.

Online purchasing (eBay)

eBay is The World's Online Marketplace® with a global customer base of 233 million. Founded by Pierre Omidyar in 1995, eBay has created a powerful marketplace for the sale of goods and services by a passionate community of individuals and small businesses. eBay now has a global presence in 37 markets, including the United States.

As an early Internet enthusiast, Pierre knew that people needed a central location to buy and sell all kinds of items on a level playing field and to meet other users with similar interests. He started eBay to fulfil this need. At the time, Pierre's fiancée (now wife) was an avid Pezâ„¢ (sweet dispenser) collector. She was having trouble finding people to trade with, and Pierre thought eBay might be the answer to her problems.

On any given day, there are millions of items listed on eBay across thousands of diverse categories, including antiques, toys, books, computers, sports, photography and electronics, amongst many others.

The internet has brought about revolutionary changes in business field. E-commerce was such a revolutionary change and it is conquering the consumers all over the world. Convenience is the main factor which attracts people to e-shopping. People no longer have to go to the busy shopping malls for buying a product. Moreover, e-shopping do not have any definite limits, including time and country, and people have the luxury of choosing the most suitable product from a huge number of sellers. Consumers prefer e-shopping because of these factors. This consumer preference for e-shopping can be understood from the phenomenal growth of companies like eBay and Amazon.

Consider the statistics of e-commerce in India. Indians changed to e-commerce only lately, but it is growing at an explosive rate. In 2006, contribution of e-commerce was $800 million, which increased to $1.2 billion in 2007 and $1.9 billion in 2008. Its contribution in the current fiscal year is $2.8 billion and it is expected to rise to $5.6 billion by 2011 (The Economic Times, 2009).

Even though economic recession has affected the growth rate of electronic shopping, its demand is increasing over the years, and with the introduction of newer technologies facilitating e-commerce in mobiles, this trend will continue in the coming years also.

The demand for laptop computers are increasing because of its reasonable prices and new technologies. In order to overcome the fierce competition from other manufacturers, most companies are introducing latest technologies in their laptops and are making them affordable by reducing the prices. The increase in demand was phenomenal with the introduction of notebooks.

The net supply of laptop in UK was 3.1 million in the year 2004, and it increased to 5 million in 2005 and to 5.6 million in 2007 (National Statistics, 2007). With the increase in demand for notebooks, the companies are increasing the supply of it, and around 3.6 million notebooks were sold in the fourth quarter of 2008 only. By looking at this trend, it can be estimated that the supply of laptops will increase in the coming years, and this period may see the dominance of notebooks.
