1) Formulas a) Total revenue i) TR = P(q)*q ii) Why little q? Because the firm can only control their output, all other firm’s outputs are assumed to be given and fixed, though in reality and more complex models, this may not be true. Even in reality, given the range of activity, the change in price is very small. b) Total Costs i) TC = c(q) ii) TC = c(K,L,N) c) Profit i) Pi = TR – TC ii) Pi = P(q)*q – c(q) iii) Pi = P(q)*q – c(K,L,N) d) Maximization i) DPi/dq = dTR/dq – dc(q)/dq = 0 ii) MR = dTR/dq = dc(q)/dq = MC iii) Produce until the last unit brings in as much revenue as it costs to make, so long as earlier units brought in more that they cost (positive but declining
