Document Summary
If you can produce the same amount of output but use less labor or capital(make one constant to analyze),then it is technological inefficient. Then b is technological inefficient,because we can use. 3 less units of labor to produce the same q=100. (compared with e) (i) w y. The total cost: a: 1001 b:805 c:420 d:150. So d is the economic efficient (ii) 50 5. So in this case, a is the economic efficient Measures of concentration (1) the four-firm concentration ratio. The ratio=0 then it is a perfect competitive market. The ratio=100 then it is a monopoly market. 60< ratio <100 it is a oligopoly market (2) the herfindahl-hirschman index(hhi) <1000 -> competitive >1800 -> uncompetitive (nearly monopoly) (3) limitations of a concentration measure (i) the geographical scope of the market (ii) barriers to entry and firm turnover. If there is only one producer in the market, then there is little or no competition.
