The Market forces of Supply and Demand
Supply and Demand * are the two words that economists use most often. * are the forces that make market economies work. * Terms refer to the behavior of people . . . as they interact with one another in markets.
Modern microeconomics is about supply, demand, and market equilibrium. * Buyers determine demand, Sellers determine supply.
Market
is a group of buyers and sellers of a particular good or service.

* Competitive market
-is a market in which there are many buyers and sellers so that each has a negligible impact on the market price.

Competition: Perfect and Otherwise

* Perfect Competition * Products are the same * Numerous buyers and sellers so that each has no influence over price * Buyers and Sellers are price takers

* Monopoly * One seller, and seller controls price

* Oligopoly * Few sellers * Not always aggressive competition

* Monopolistic Competition * Many sellers * Slightly differentiated products * Each seller may set price for its own product

Demand * Quantity demanded is the amount of a good that buyers are willing and able to purchase. * Law of Demand * The law of demand states that, other things equal, the quantity demanded of a good falls when the price of the good rises.

The Demand Curve: The Relationship between Price and Quantity Demanded

* Demand schedule is a table that shows the relationship between the price of the good and the quantity demanded.

* Demand curve is a graph of the relationship between the price of a good and the quantity demanded.

Market demand refers to the sum of all individual demands for a particular good or service.

Graphically, individual demand curves are summed horizontally to obtain the market demand curve.

ALTAF KHAN BOOK REVIEW:- Prof. Mullick and Prof. Khan has written this book with an objective to present a well-documented theory on supply chain management. Supply chain is a network of facilities and distribution options that performs the functions of procurement of materials, transformation of these materials into intermediate and finished products, and the distribution of these finished products to customers. Supply chain management is typically viewed to lie between fully vertically integrated firms, where the entire material flow is owned by a single firm, and those where each channel member operates independently. There are four major decision areas in supply chain management which are location, production, inventory and transportation and there are both operational elements in each of these decision areas .In essence, supply chain management integrates supply and demand management within and across companies.

Understanding Nrega: a Simple Theory and Some Facts

...CDE January 2011 UNDERSTANDING NREGA: A SIMPLE THEORY AND SOME FACTS Diganta Mukherjee Email: digantam@hotmail.com Unitedworld School of Business Kolkata Uday Bhanu Sinha Email: uday@econdse.org Delhi School of Economics University of Delhi Working Paper No. 196 Centre for Development Economics Department of Economics, Delhi School of Economics Understanding NREGA: A Simple Theory and Some Facts * Diganta Mukherjee # and Uday Bhanu Sinha Abstract A developing economy like India is often characterised by a labour market with demand and supply of labour and a wage that even if competitively determined may not be adequate for the poor household to reach their target income; what they consider as means of a decent living. Envisaging situations like these, the Indian government has implemented the National Rural Employment Guarantee Act (NREGA) in recent past, to complement the income of the poor by providing them employment for certain number of labour days in a year. In this paper, using a simple theoretical model, we have analysed the impact of NREGA scheme on (i) rural labour market, (ii) income of the poor households and (iii) overall agricultural production. It is seen that the income from NREGA alone can be a substantial part of the target income of the poor. We show that in such a situation, the poor may exhibit a backward bending supply curve of labour which may lead to an aggregate reduction in agricultural output. This adverse production effect...

Therefore, the long introduction has been shortened, the confusing diagram (former Figure 12-2) has been removed, and the extra part concerning outline of the chapter has been removed. The derivation of the IS curve section has been rewritten at the beginning. Box 11-1 and Box 11-2 and 11-3 are new The LM curve section has been rewritten to make it more clear, and the relevant diagrams are now side by side, which makes much more sense.

This paper mainly focuses on the recent recession and how is IT impacted and transformed during these conditions. Having discussed the history of IT in different market situations, this paper throws a light on future conditions and growth in the field of IT. DEMAND ANALYSIS OF IT IN DIFFERENT MARKET CONDITIONS Introduction Demand is an economic principle that tells us about consumers' want, readiness and their capability to pay a price for a specific good or service. It is a common belief that greater the demand, greater is the price of a good or service. But, what leads to the demand of a particular good/service is a complex analysis and is different for each good/service. Any business, before development or expansion, studies the demand for its product. This study of demand is a complex process. Based on this demand analysis report, a firm leadership would decide on extension or starting of the business. The demand analysis might help determine or justify a desire for expansion in a particular sector or just to assess the health of a particular sector. Even though the demand analysis procedure is performed differently based on the type of business or study, participants...

The advertisment could be a little more on the aggressive side to see what it is customers like, and to add to the strategy, it will make sense to aim towards more inexperienced internet users.
