Economics is the study of how society 
chooses to employ resources to produce goods 
and services and distribute them among 
competing groups and individuals.        lOMoAR cPSD| 59078336 BRANCHES OF ECONOMICS 
Macroeconomics: Concentrates on the  operation of a nation’s  economy as a whole.    Microeconomics:  Concentrates on the  behavior of people and  organizations in markets for  particular products or  services.    RESOURCE DEVELOPMENT      lOMoAR cPSD| 59078336
Resource Development -- The study of how to 
increase resources and create conditions that will 
make better use of them. We accomplish this by:    • New Technology  • New Methods  • New Processes  • Better Resources  EXAMPLES  of  RESOURCE  DEVELOPMENT      lOMoAR cPSD| 59078336
• Making resources last longer -  Recycling 
• New energy sources - Hydrogen  fuel  • New ways of  growing foods -  Hydroponics 
• New ways of creating goods and  services  – Aquaculture  – Nanotechnology   
Resource Development is often referred to as the New  Economy.        lOMoAR cPSD| 59078336 Economic Systems 
CAPITALISM is an economic system in which all or most of the 
factors of production and distribution are privately owned and  operated for profit.   
SOCIALISM is an economic system based on the premise that some, 
if not most, basic businesses should be owned by the government 
so that profits can be distributed among the people.   
COMMUNISM is an economic and political system in which the 
state (the government) makes almost all economic decisions and 
owns almost all the major factors of production.   
Note: These are nothing but economic philosophies of how 
society (country) chooses to employ its resources.  TWO MAJOR  ECONOMIC SYSTEMS      lOMoAR cPSD| 59078336
• Free-Market Economies -- The market largely 
determines what goods and services are produced, 
who gets them, and how the economy grows.  (Capitalism) 
• Command Economies -- The government 
largely determines what goods and services are 
produced, who gets them, and how the economy will  grow. (Socialism, Communism}  2-7  MIXED ECONOMIES 
• Note: Neither free-market nor command economies 
have created sound economic conditions so countries 
use a mix of the two economic systems.      lOMoAR cPSD| 59078336
• Mixed Economies -- Some allocation of resources is 
made by the market and some by the government. 
• Although the U. S. subscribes to the Capitalism 
philosophy, the U.S. does employ some 
Socialism and Communism philosophies    making it a mixed economy.  2-8 
Limits of Free-Markets (Capitalism) 
• Inequality of Wealth Causes National & World Tension    • Greed Compromises Ethics   
• Limitations Push Country towards Socialism, which  Leads to More Government      lOMoAR cPSD| 59078336 Regulation  Trends in World Economies 
• Communist governments are disappearing.  • Socialist governments are  cutting back on social  programs, lowering taxes and  moving toward capitalism.  • Capitalist countries are 
increasing social programs and  moving more toward socialism.  FOUR DEGREES 
of COMPETITION or FORMS of CAPITALISM      lOMoAR cPSD| 59078336 1. Perfect or Pure  Competition  2. Monopolistic  Competition  3. Oligopoly  4. Monopoly  EXAMPLES 
Perfect (Pure) Competition: Many sellers, similar 
products. Example Agricultural Products  Kansas Nebraska   VS.  Wheat Wheat        lOMoAR cPSD| 59078336
Monopolistic Competition: Large number of sellers, 
products differ but are close substitutes. Example Fast  Food    EXAMPLES 
Oligopoly: Few sellers that dominate market.  Example Soft Drinks        lOMoAR cPSD| 59078336
Pure Monopoly: Single seller has all the sales. Example   Public  Utilities    PRICING      lOMoAR cPSD| 59078336
• A seller may want to sell shirts for $50, but only a few 
people may buy them at that price. This creates a  surplus of goods. 
• A seller lowers the price to $30, 
more people than normal buy the 
shirts. This creates a shortage of  goods. 
• The seller establishes a price of $40  based on what consumers are 
willing to pay and what the seller is  willing to provide.  SUPPLY CURVES 
• Supply -- The quantities of products businesses are 
willing to sell at different prices.      lOMoAR cPSD| 59078336   DEMAND CURVES 
• Demand -- The quantities of products consumers are 
willing to buy at different prices.      lOMoAR cPSD| 59078336         lOMoAR cPSD| 59078336                           Price Elasticity 
When Elastic Demand exists, a slight decrease in the 
price of a product results in a relatively large 
increase in demand or items sold. On the other      lOMoAR cPSD| 59078336
hand, a slight increase in price results in a relatively 
large decrease in demand or items sold. In other 
words, people are price sensitive. When Inelastic 
Demand exist, a slight increase or decrease in price 
will not significantly change the demand or items 
sold. However, lowering price will increase the 
quantity sold but revenues will decrease. In other 
words, people are not as price sensitive.      lOMoAR cPSD| 59078336 Price Elasticity                                lOMoAR cPSD| 59078336 Elasticity Example  Elastic Demand    Price  Demand  Revenue  $7.00 50  $350.00  $9.00 20  $180.00  Inelastic Demand      Price  Demand  Revenue  $7.00 50 $350.00 $9.00 47  $423.00      lOMoAR cPSD| 59078336
SOME DETERMINANTS OF ELASTICITY 
Price elasticity can vary with products and services. 
A product could have elastic demand in one part of 
the country and inelastic demand in another part of 
the country. Also price elasticity for a product or 
service is influenced by several factors.   
Availability of Substitutes: If a product or service 
has close substitutes, demand would be elastic. 
However if a product or service has few substitutes, 
demand would be inelastic. For example, a new 
shirt or blouse has many possible substitutes, but 
gasoline has almost no substitutes.
