![]() ![]() This is because factors of production are not equally productive in all uses. Note also that the PPF is a curved line, bending out (concave) from the origin. There are competing uses of resources, so they are scarce. It therefore follows that, given our current limited stock of resources, to increase the production of one good means sacrificing some production of the other good. But this point lies outside of the PPF, indicating that more resources (factors of production) are required. At this point the economy would be producing more of both wheat and tractors, compared to point F. The PPF illustrates how resources are scarce. The curved line AB shows all the possible combinations of output of wheat and tractors that could be produced, provided that all resources are employed.įor instance, at point C it could produce OW tractors and OR tons of wheat: If all resources were devoted to wheat production, it could produce OB tons, and zero tractors. In the diagram (Fig 1) below, if country x devoted all its resources to tractor production it could produce OA tractors in a year, and zero tons of wheat. The country has a given quantity of factors of production which it can allocate to the production of either good. The economy of country X can produce two goods only (let’s call them wheat and tractors). We can represent the concepts of scarcity, choice and opportunity cost in a simple two dimensional diagram called a production possibility frontier ( PPF) diagram.
