Is there a formula to calculate this? I came across the following question which asked for it:Laspeyre index for price in 20X5 ( with base year of 20X0) 150 Corresponding Passche index 138.24What is Fisher’s ideal index? What is the logic behind Fisher’s ideal index and its relationship with these two numbers?

It is a better indicator than either of the two indices on their own (I explain the problems with Laspeyre and Paasche in my free lectures).However it is not examined in Paper MA.AuthorPostsViewing 2 posts - 1 through 2 (of 2 total)You must be logged in to reply to this topic.Log In Username: Password: Keep me signed in Log In
