tailieunhanh - Lecture Principles of economics - Chapter 3: Supply and demand

This chapter introduces two Core Principles (Equilibrium, Efficiency) and develops the basic supply and demand model. In this chapter, students should be able to: Describe how the demand and supply curves summarize the behavior of buyers and sellers in the marketplace, discuss how the supply and demand curves interact to determine the equilibrium price and quantity, illustrate how shifts in supply and demand curves cause prices and quantities to change. | Supply and Demand Chapter 3 McGraw-Hill/Irwin Copyright © 2015 by McGraw-Hill Education (Asia).

Discuss how the supply and demand curves interact to determine equilibrium price and quantity. Illustrate how shifts in supply and demand curves cause prices and quantities to change Explain and apply the Efficiency Principle and the Equilibrium Principle (also called “The No-Cash-on-the-Table Principle). 2 What, How, and For Whom? Every society answers three basic questions WHAT Which goods will be produced? How much of each? HOW Which technology? Which resources are used? FOR WHOM How are outputs distributed? Need? Income? 3 Central Planning versus the Market Central Planning Decisions by individuals or small groups Agrarian societies Government programs Sets prices and goals for the group Individual influence is limited The Market Buyers . | Supply and Demand Chapter 3 McGraw-Hill/Irwin Copyright © 2015 by McGraw-Hill Education (Asia).
