In this prоblem, we аnаlyze prоductiоn plаnning in two different types of widget markets. In one city, widget production is split across many different manufacturers: these firms are in perfect competition with one another. Here, marginal revenue per widget is constant at $4 (displayed on the left half of the marginal revenue column below). In another city, a single firm handles widget production, and constitutes a monopoly. Marginal revenue is decreasing, as shown in the right half of the marginal revenue column below. # of workers total product marginal revenue 1 12 $4 / $4 2 22 $4 / $4 3 31 $4 / $3 4 38 $4 / $3 5 44 $4 / $2 6 48 $4 / $2 7 51 $4 / $1 8 52 $4 / $1 Let the wage in both markets be $18. How many workers does the firm in perfect competition hire? [wpc]. What are total profits? $[ppc]. How many workers does the monopolist hire? [wm]. What are total profits? $[pm].
