which shape is most common in ppf
What shape does a PPF take if it displays increasing opportunity costs? What about if there are constant opportunity costs? Which shape is most common in production situations? Why? The shape that a PPF takes if it displays increasing opportunity costs is a curved shape. If there are constant opportunity costs, it is a linear graph. The most common is the curved graph because you have to factor in all the other variables such as labor, human needs, inconveniences â basically all the factors that will not be able to be accounted for on a linear graph.
