Data frequency and exchange rate pass-through : evidence from India's exports

This paper studies the pricing behavior of Indian exporters using both annual and monthly data in order to uncover the role of data frequency in determining variation in the degree of short and long-run exchange rate pass-through (ERPT). Export price data during the post-1991 economic reforms period is disaggregated at the two-digit industry level and using a novel methodology in the ERPT literature (cointegration for heterogeneous panels) cross-industry differences in adjustment are identified. We observe that there is clear evidence of incomplete ERPT to prices in India's export markets, after having controlled for the level of exchange rate volatility and domestic inflation as an indicator of variations in marginal cost. The empirical results indicate that monthly data reflect more incomplete ERPT to destination market prices, relative to annual data, in which all the short run rigidities are more likely to have been adjusted. Thus studies that use higher frequency data are more likely to find incomplete ERPT in the short-run, even in the context of an emerging market economy. In the long-run, incomplete ERPT subsists in a few industries for both data frequencies.
