HERFINDAHL INDEX: A measure of concentration of the production in an industry that's calculated as the sum of the squares of market shares for each firm. This is an alternative method of summarizing the degree to which an industry is oligopolistic and the relative concentration of market power held by the largest firms in the industry. The Herfindahl index gives a better indication of the relative market control of the largest firms than can be found with the four-firm and eight-firm concentration ratios.

I've been offered another job -- an opportunity to wander around the streets of the distant mecca of Shady Lane to search out the mysteries of plant pathology. In Shady Lane, the sidewalks are smoother, the crosswalks are better, and the pay is much more lucrative. However, in that Shady Lane is in another time zone and several states away, migration would be my last topic of the day. There's a lot to be gained from this potential relocation of my residence, but it's not without cost. While I ponder this decision, perhaps you can help out by considering the topic of migration.
