Production Possibilities Model Production Possibilities Curve: – A graphical representation of the various combinations of maximum output that can be produced from the available resources and technology – Assumptions: Full employment Use of the best technology available Productive efficiency 1-20© 2012 McGraw-Hill Ryerson Limited LO6

Production Possibilities Model 1-21© 2012 McGraw-Hill Ryerson Limited LO6

Figure 1.1 Unattainable x a b c d e Wheat Cars Attainable f LO6 © 2012 McGraw-Hill Ryerson Limited points on the curve represent maximum output possible with available resources

Production Possibilities Model Scarcity – Represented by points outside the curve Choice – Represented by points on the curve (efficient) and points within the curve (inefficient) Opportunity Cost – Represented by the downward slope of the curve 1-23© 2012 McGraw-Hill Ryerson Limited LO6

Law of Increasing Opportunity Costs – Factors of production are not equally suitable – As output increases, the per unit costs of additional units increases – Gives the production possibilities curve its bowed out shape 1-24© 2012 McGraw-Hill Ryerson Limited LO6
