How high is exchange rate pass-through in India? Has it changed over time?

Concerns about relatively high degrees of exchange rate pass-through in a number of emerging economies have contributed to a fear of floating. Despite the obvious policy relevance of this issue there is hardly any existing literature that has examined aggregate CPI pass-through for India, which has been liberalizing its economy since 1991. This paper estimates exchange rate pass-through (ERPT) at the aggregate level into India's CPI for the period 1980Q1 -2005Q3. We also analyze whether exchange rate pass-through in India has changed over time, particular since 1991, which was the beginning of the country's economic liberalization program.
