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 Possibilities Frontier
Used to illustrate: Productive Capacity Opportunity Costs Efficiency Productive Allocative Economic Growth/Decline Vital Link to Aggregate Supply (short/long run)

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
. . . 80 70 60 50 40 20 10 Wheat Rice Wheat . 80 78 70 55 38 20 40 60 80 100 -2 +20 -8 +20 . -15 +20 -17 +20 -38 +20 . NOTE: The GAIN in Rice is CONSTANT while the LOSS In Wheat is INCREASING each Time…What is going on??? Rice

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

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

. . A Capital Goods “Stuff you use to make other Stuff” Tools, equipment, factories, other infrastructure Capital Goods B . C . Consumer Goods “Stuff” for immediate Consumption. Food, consumer Electronics, etc. D Allocative Efficiency Where a society decides to Produce on its PPF. A value Decision based on values/politics . 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 Capital Goods .D 1000 Consumer Goods

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 Capital Goods .D 1000 Consumer Goods

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 Capital Goods .D 1000 Consumer Goods

Lets take a closer look at the PPC. What do the different points on the PPC represent? 100 .A .B .C .D 1000 Consumer Goods

Each point represents Productive Efficiency This means that this economy is allocating ALL of it productive resources in the least costly way 100 .A .B .C .D 1000 Consumer Goods

There are an infinite number of points on the PPC. Where a society decides to produce is called Allocative Efficiency This represents the combination of Capital and Consumer Goods most desired by the society 100 .A .B .C .D 1000 Consumer Goods

The WHOLE PPC represents “FULL PRODUCTION” Productive Efficiency Full-Employment of Resources 100 .A .B .C .D 1000 Consumer Goods

PPC and Efficiency Point C is efficient: all resources are fully employed A Q Maize Point E is inefficient: some resources are unemployed F C Point F is unattainable given current resources and technology E D Q Wheat

Do economy’s always produce on the PPC? No! Often they operate inside their production possibilities .A 100 .B .C E .D 1000 Consumer Goods

Do economy’s always produce on the PPC? Point “E” represents a point inside the PPC. Notice that this point “E” represents a lower bundle of Capital and Consumer Goods .A 100 .B .C .E .D 1000 Consumer Goods

Do economy’s always produce on the PPC? Point “E” represents a point inside the PPC. The area between point “E” and the PPC represents underutilization of resources or under-employment of resources or unemployment. The economy is being inefficient. .A 100 .B .C .E .D 1000 Consumer Goods

Do economy’s always produce on the PPC? Point “E” represents a point inside the PPC. This economy could be doing better… .A 100 .B .C .E .D 1000 Consumer Goods

Do economy’s always produce on the PPC? How about point “F”? Point F is outside our PPC It represents a combination of Capital and Consumer Goods that is currently not possible with this economies resources .A 100 .B .F .C E .D 1000 Consumer Goods

Do economy’s always produce on the PPC? How about point “F”? Point F is outside our PPC This point is desirable (more “stuff”) but currently not attainable. .A 100 .B .F .C E .D 1000 Consumer Goods

. . . A Capital Goods “Stuff you use to make other Stuff” Tools, equipment, factories, other infrastructure Capital Goods G B . C . Consumer Goods “Stuff” for immediate Consumption. Food, consumer Electronics, etc. . D F Allocative Efficiency Where a society decides to Produce on its PPF. A value Decision based on values/politics . E Productive Efficiency Full-employment of resources And producing at the lowest cost Consumer Goods

Production Possibilities Curve The PPC shows ALL possible combinations of two goods that can be produced if ALL available resources are fully employed (used) with the best technology currently available How do we get to point G?? 1. Technological advancement which increases Productivity 2. Discover new resources 3. Take resources (War) 4. Trade for Resources A B G C Robotics (Capital Good) D F E Compact Discs (Consumer Good) “OUR ECONOMY IS DRIVEN BY TECHNOLOGICAL ADVANCEMENT” CAN YOU THINK OF AN EXAMPLE IN HISTORY WHEN WE WERE INSIDE THE PPC?

[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. Possibilities-A, B, C, D, & E Impossibility [more/better resources, better technology]

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
