CF: HHI after a merger

someone, between, anything
I know that HHI of 1000 -1800 is "moderately concentrated"

also

if HHI goes up by more than 100 after merger, and HHI is between 1000 and 1800, then it will be opposed by regulators

can someone please help me with other HHI information

what does HHI mean if it is below 1000?

anything else?

i just want to get this straight:

if HHI after merger is > than 1800, if the HHI increased by more than 50 it is a challenge?

but between 1000 - 1800, it has to increase by more 100 to be challenged?

------

also

low HHI is .... basically bad, fragmented industry?

is that correct?

Low HHI - competitive industry I think i.e. not concentrated. Low HHI is a good thing..

ok I'm confused (not the first time)

First: is HHI the same or similar to HI? Herfindahl INdex?

With the Herf Index we want it to be high, high HI means the industry is not fragmented, more oligopolistic

----

What is the difference between HI and HHI?

They're pretty much the same thing. HHI uses the market shares in % form and the HI uses them in decimal form. I'm not sure why though...someone else can chip in here to help?

i believe the herfindahl is only the top 50 firms while the HHI is ALL firms an industry. i might have those two mixed up but the basic premise is the same
