The Production Function • The production function : The relationship between quantity of inputs

The Production Function • The production function : The relationship between quantity of inputs used to make a good and the quantity of output of that good.

• The marginal product (MP) : The increase in output that arises from

• The marginal product (MP) : The increase in output that arises from an additional unit of input. • Marginal product of labour (MPL) • Diminishing Marginal Product : ? • The production function slope is the change in output from each additional input. • Then, the slope of production function is the marginal product of labour. • ยงใสคนงานเขาไปเพม MP ยงลด กราฟ production function กจะคอยแบนขน (ชนนอยลง (

MPL = Slope of Production Function

MPL = Slope of Production Function

• Now we got Total cost curve. • Total Cost vs Marginal Cost

• Now we got Total cost curve. • Total Cost vs Marginal Cost • Marginal Cost คอ ? – An increase in total cost that arises from an extra unit of production – MC = d. TC/d. Q

• Total, Marginal, Average • Average Total Cost, Average Fixed Cost, Average Marginal

• Total, Marginal, Average • Average Total Cost, Average Fixed Cost, Average Marginal Cost TC = FC + VC ATC = TC/Q AFC = FC/Q AVC = VC/Q MC = d. TC/d. Q

ATC = AFC + AVC

ATC = AFC + AVC
