Chris Lavery    Research Project:    Industry Concentration    Industry  assiduousness has  dickens forms of measurement. The first is based upon a 100% concentration of  all in all the firms in a certain industry. This is known as the concentration ratio and represents the value of the top firms of an industry stated as a percent of the total industry scales. The other  typecast of concentration measurement is known as the Herfindahl  great power and is  cipher by squaring the individual producers percentage of the market and adding them together. For instance, if there were 5 firms in an industry and they each had 20% of the total output, the Herfindahl index would be; (20 squared) + (20 squared) + (20 squared) + (20 squared) + (20 squared)= 2000.

 An example of these concentration ratios, taken from the 1997 US  presidency economic census, are as follows:  4-Firm Concentration Ratio     Herfindahl Index   heart and soul products:                                                   35                                    393  Fruit and vegetable canning:                              24                                    259     Breakfast  food grain:                                                82                                   2,445  Womens and and misses dresses:                   13                                     76  Book printing:           32                                    364   stationery:                                                          56                                   1,128  Soap and detergent:          66                                    1,619  Mens  footwear:                     50                                     857  Womens footwear:                     50                                     795  Bolts, nuts, rivets, washers:           9                                       40  Electronic  information processing system:          45                                     728   Radio, TV, wireless broadcasting:                     49...
