“…A number of other studies have used the Hodrick-Prescott (HP) method to estimate the output gap for India -Callen and Chang (1999), Ray and Chatterjee (2001), Srinivasan(2009), Dua and Gaur (2009), Kundan (2009), andPaul (2009). It is interesting to note that even though they use the HP approach, Callen and Chang (1999) list several drawbacks to this approach.Ozbekand Ozlale (2005) point out that the HP filter cannot capture the excessive boom-and-bust cycle along with volatile output, which is a well-known characteristic of many emerging markets.…”
