<P> During the early stages of production MP is greater than AP . When the MP is above the AP the AP will increase . Eventually the MP reaches it maximum value at the point of diminishing returns . Beyond this point MP will decrease . However , at the point of diminishing returns the MP is still above the AP and AP will continue to increase until MP equals AP . When MP is below AP , AP will decrease . </P>
