Analysis of the Relationship between Trade Openness and Inflation: Evidence from MIKTA Countries

Foreign trade plays a key role in the development of a country's economy and international social relations. Accordingly, the increase and decrease in a country's trade openness directly and indirectly affects macroeconomic indicators. In short, it is important to know the expected relationship between trade openness and inflation for a country's economy. Investigating the relationship between trade openness and inflation is important in keeping inflation under control, along with foreign trade policy practices. On the other hand, the theoretical basis of the association between trade openness and inflation is known with the Romer (1993) Hypothesis. According to the Romer Hypothesis, it is argued that an increase in trade openness will negatively affect inflation. However, although there are findings supporting this theory for the studies done so far, there are empirical studies expressing the opposite. This study has investigated this relationship in MIKTA countries. Kónya (2006) panel causality test was used in the study using annual data between 1960 and 2020. In result of the this study, it was found that there is no causal linkage between trade openness and inflation in countries. These results do not coincide with the Romer (1993) Hypothesis.
