Enter a numeric response using an infeger) stion

Explanation / Answer

Answer:

The formula for Herfindahl–Hirschman Index is as follows -

H = sum of (market share)2 of total firms

So, here H = (44)2 + (35)2 + (20)2 + (1)2 = 1936 + 1225 + 400 + 1 = 3562.

Now from theorem as we know any value of H above 2500 is indicating highly concentrated market, so we can conclude that, there is high concentration in the market as the market's level of concentration is 3562.
