2. Draw a production function that exhibits diminishing marginal product of labour. Draw the associated total-cost curve. (In both cases, be sure to label the axes.) Explain the shapes of the two curves you have drawn.
We know that the average product of labour is the total

Problems and Applications 1. A commercial fisherman notices the following relationship between hours spent fishing and the quality of fish caught:
What is the marginal product of each hour spent fishing?
Use the data to graph the fisherman’s production function. Explain its shape

a) Hours | In pounds | MP | 1 | 10 | - | 2 | 18 | 8 | 3 | 24 | 6 | 4 | 28 | 4 | 5 | 30 | 2 |

b) Hours | In pounds | TP | AP | MP | 1 | 10 | 10 | 10 | - | 2 | 18 | 28 | 9 | 8 | 3 | 24 | 52 | 8 | 6 | 4 | 28 | 80 | 7 | 4 | 5 | 30 | 110 | 6 | 2 |

120 | | | | | | 100 | | | | | | 80 | | | | | | | | | | TP | | 60 | | | | AP | | | | | | | | | | | | MP | | 40 | | | | | | 20 | | | | | | 0 | | | | | | 1 | 2 | 3 | 4 | 5 | |

TP – constantly grow, so curve has positive slope
AP and MP constantly fall, so curve has negative slope

c)

| | | TC | | | 40 | | | | | | 35 | | | | | | 30 | | | | | | 25 | | | | | | 20 | | | | TC | | | | | | | | 15 | | | | | | 10 | | | | | | 5 | | | | | | 0 | | | | | | 1 | 2 | 3 | 4 | 5 | |

TC – constantly grow because variable costs grow in equal proportion, so curve has positive slope
