Globalization and inflation dynamics: evidence from emerging economies.

We test the impact of globalization on the inflation process (global slack hypothesis) for 15 emerging economies over the period (1996Q1-2019Q4). The novelty of this article lies in testing the impact of globalization on the inflation process. We introduce the smooth transition regression (STR) model of the Phillips curve to capture the gradual impacts of globalization on inflation dynamics. The main results are as follows. (i) The asymmetries in inflation exist that are not captured by the linear Phillips curve. (ii) The domestic output gap remains a main driving force of inflation. (iii) Globalization based on the trade weighted average of the domestic output gap does not affect the inflation process compared to other variables like the trade openness, import prices, real exchange rate and international oil prices. Our results yield important implications that the central banks of the emerging economies can stabilize inflation and output gap in an effective way, exploiting the inflation-output gap relationship. When economic expansion of the trading partners increases, the process of inflation dynamics changes in two economies (Brazil, and China). [ABSTRACT FROM AUTHOR]
