Outline how the production possibility frontier can be used to demonstrate opportunity cost and examine how the effects of unemployment and technical change on production in the economy.
A production possibility frontier is a basic model that can examine the efficiency of an economy’s resource use, irrespective of the wants of that economy. A production possibility frontier is the simplest tool usable to demonstrate opportunity cost, at all possible combinations of two goods in production, the extremes being maximum Good A production with no Good B production, and maximum Good B production, with no Good A production. In all PPFs, a series of rules must be followed. They can be summed up with the term ceteris paribus (all things remaining equal). Ceteris Paribus relies on the following assumptions: * The economy can only produce two resources. * These resources are at a fixed quantity. * These resources are fully mobile. * Technology will remain at a constant rate. * The economy is a closed one.
An example of a basic production possibility frontier is shown in Fig. 1 below.

As seen in Fig. 1 above, a PPF can easily demonstrate opportunity cost. The opportunity cost of moving from point Q, to point R on the frontier for example, is 5 units of Good A, given up to produce 3 extra units of Good B. Plotting A on the Y axis, it is easy to see that moving 5 units down, yields 5 units less of that good for the production of 3 units right along the X axis (Good B). Two new points have been added to Figure 1 that do not lie on the frontier; Point Y and Point Z, to make Figure 2 below. At this point, in this stage of Zogg’s economic development, Point Y is possible to be achieved however point Z is not. Because the frontier itself marks the maximum production capacity of the possible combinations of Good A and Good B, it is possible indeed to be
