Exchange-rate pass through, openness, and the sacrifice ratio

摘要

Considerable recent work has reached mixed conclusions about whether and how globalization affects the inflation-output tradeoff and suggests that the ultimate effect of openness on the output-inflation relationship is influenced by a variety of factors. In this paper, we consider the impact of exchange-rate pass through and examine how pass through conditions the effect of openness on the sacrifice ratio. We develop a simple theoretical model showing how the extent of both pass through and openness can interact to influence the output-inflation relationship. Next we empirically explore the nature of these two variables and their interaction. Results indicate that greater pass through increases the sacrifice ratio, that there is statistically significant interaction between pass through and openness, and-once the extent of pass through is taken into account alongside other factors that affect the sacrifice ratio, such as central bank independence-openness fails to exert an empirically robust effect on the sacrifice ratio.
