The phenomenon of Exchange Rate Pass-Through (ERPT) has long been a question of
interest. It was rekindled in the 1970s by a combination of rising inflation and the adoption of
more flexible exchange rate regimes in many countries following the demise of the Bretton
Woods system of adjustable pegs. In this high-inflation environment, concern increased
among central bankers about the potential effects of movements in their currencies on
inflation (McCarthy, 2000).
Since then, a large body of economic literature has studied the ERPT to various
domestic price measures. The empirical literature examines the role played by ERPT in both
small as well as large economies.
McCarthy (2000) analyzes the impact of the exchange rate changes and import
prices on producer and consumer prices in a recursive VAR framework. Using data from
six industrialized OECD countries, he finds that the exchange rate has a modest effect
on consumer prices. He also finds that the pass-through tends to be correlated with the
value of consumer prices as well as the degree of trade openness of the country.
Goldfajn and Werlang (2000), in a panel study using a sample of 71 countries, find
that the main determinants of pass-through are the cyclical component of output, the
initial overvaluation of the real exchange rate, the initial rate of inflation, and the degree of
openness. Among them, the real exchange rate misalignment is the most important determinant
for emerging markets, while for developed countries, the most important determinant is
initial inflation.
Choudhri and Hakura (2001), also using a 71-country data, consisting of both
developed and developing nations, find a strong positive association between pass-through and
the average inflation rate across countries. The inflation rate is found to dominate
other macroeconomic variables in explaining cross-country differences in pass-through.
Similarly, in 122 countries, Devereux and Yetman (2003) find a positive nonlinear relationship
between pass-through and mean inflation and exchange rate. |
