Abstract

Are global inflation synchronization and the flattening of the Phillips curve across the globe related? The globalization hypothesis has been proposed to explain the relationship but questions remain on its quantitative role. Focusing on South Korea, one of Asia-Pacific supply chain hubs, this paper investigates the extent to which import prices affect domestic price inflation over the period between 2002 and 2020. Specifically, we conduct the regression decomposition method to identify major sources of variation in domestic inflation, followed by a subsequent set of comparative analyses across various inflation forecasting models. Our findings confirm a tight link from import prices to domestic prices, with a 10pp increase in IPI inflation passed onto PPI and CPI inflation by 3.9pp and 3.4pp over time, respectively. The main finding of this study is consistent with the recent global inflation surge that has been driven largely by imported food and energy price channels.
