Starter Make a table with two columns – “WANTS” and “NEEDS” In each column write down ten things that you, right now in your life, want or need and write a price (estimate) for each Total the price at the bottom of your table Then below this total, write down your monthly income

Trade-offs Opportunity Costs When faced with SCARCITY of resources, decisions have to be made about how to use those resources Trade-offs Opportunity Costs

The Economic Problem Most of us want better food, clothing, housing, schooling, holidays, hospital care, and entertainment – Unlimited wants and needs But there is not enough to go around – Limited resources This gives rise to the basic economic problem of choice under conditions of scarcity. If we cannot have everything we want, we must choose what we will and will not have.

Trade-Offs This is the decision making process that is occurring in your mind right now! Am I going to pay attention to what Ms. Haggerman is saying, or am I going to text on my phone? Am I going to come to class or ditch? Am I going to stay in school or go find a full time job? Each and every decision you make has a cost!! Not necessarily a cost in dollar terms, but a cost in that you must give up something in order to get more of something else.

Opportunity Cost The “price you pay” for each decision you make is called the OPPORTUNITY COST. Opportunity cost is vital to the understanding of economics. “The amount of a product or service that must be forgone (given up) in order to obtain more of the next best alternative product or service”

Economy’s Resources An economy’s resources fall into four main categories: Land – Land, forests, minerals Labour – Human resources Capital – Tools, machinery, factories Entrepreneurs – People who take risks by introducing new products and new ways of making old products

Production Possibility Curve We are now going to illustrate on a diagram some of the issues surrounding economic choices. Production Possibility Curve – Shows the maximum amount of two products that can be made in this time period with current resources and technology

Production Possibilities Frontier Increasing Opportunity Costs The type of land resource suitable for growing Wheat is DIFFERENT than the land resource for growing Rice. If a society wants MORE Rice, then as you convert land suitable for growing Wheat (arable, relatively dry) so that you can grow Rice (wet, swampy) it will become MORE costly to do that, in terms of Wheat production We have INCREASING OPPORTUNITY COSTS of producing Rice in terms of Wheat

Production Possibilities Frontier Economy’s produce MORE that just Wheat and Rice. We produce LOTS of goods of many different types. We can broadly categorize goods into TWO categories Capital Goods and Consumer Goods

The PPC shows the relationship between two goods: The best way to illustrate Trade-Offs and Opportunity Costs is to use a Production Possibilities Curve The PPC shows the relationship between two goods: 1. Capital Goods (Investment Goods) Goods that satisfy our wants INDIRECTLY and promote future growth or “happiness” – Delayed gratification. 2. Consumer Goods Goods that satisfy our wants DIRECTLY. Instant Gratification Lesson 1 Act 1

E Productive Efficiency Full-employment of resources And producing at the lowest cost Consumer Goods

Production Possibilities Curve (Frontier) The reason the PPC is bowed is because of INCREASING OPPORTUNITY COSTS. At Point “A” the economy gives up 10 capital goods in order to get 400 consumer goods. 400 Consumer goods = 10 Capital goods 1 Consumer good = 10 Capital goods/400 1 Consumer good = .025 Capital good 100 .A .B .C 10 20 30 40 50 60 7 0 80 90 Capital Goods .D 100 200 300 400 500 600 700 800 900 1000 Consumer Goods

Production Possibilities Curve (Frontier) The reason the PPC is bowed is because of INCREASING OPPORTUNITY COSTS. At Point “B” the economy gives up 10 Capital goods in order to get 200 more Consumer goods. 200 Consumer goods = 10 Capital goods 1 Consumer good = 10 Capital goods/200 1 Consumer good = .05 Capital good 100 .A .B .C 10 20 30 40 50 60 7 0 80 90 Capital Goods .D 100 200 300 400 500 600 700 800 900 1000 Consumer Goods

Production Possibilities Curve (Frontier) The bowed nature of the PPC is due to INCREASING OPPORTUNITY COSTS Not all resources are adaptable to alternative uses. Resources used for Capital Goods may not be suitable to make Consumer Goods (and Vice Versa) Marsh land suitable for growing rice could not easily be converted for use as a an airport. It would be much more costly than using farmland in Kansas. 100 .A .B .C 10 20 30 40 50 60 7 0 80 90 Capital Goods .D 100 200 300 400 500 600 700 800 900 1000 Consumer Goods

[more/better resources, better technology] Economic resources are not completely adaptable to alternative uses. The “curve” indicates a “changing trade-off.” Obtaining more of one good requires giving up larger amounts of the alternative good.

Going to War (U. S. ) When the U. S Going to War (U.S.) When the U.S. entered WWI, we had severe unemployment. We were able to step up production of consumer goods and war materials simply by getting to full production. We went from 14.6% unemployment in 1940 to 1.2% in 1944. Over 7 million people went to work that were not working in 1940. United States [Beginning of WWII] C War Goods F Civilian Goods Going to War(Russia). Russia, on the other hand, entered WWII at full capacity. So their preparedness entailed a shifting of resources from civilian goods and a drop in their standard of living. The U.S. position was similar as we entered the Viet Nam War at full employment. We increased both military spending and domestic spending on the “War on Poverty.” Our attempt to achieve more “guns and butter” in a FE economy was doomed. We were trying to spend beyond capacity and ended up with double digit inflation in the 1970s. C Russia [Beginning of WWII] War Goods D Civilian Goods
