Türkiye'de akaryakıt fiyatlarının gıda enflasyonuna etkisi

In the aftermath of the Covid 19 pandemic, food inflation is a fundamental problem that policymakers around the world, especially in Turkey, have been focusing on. Various factors play a role in the rise in food inflation. One of these factors is fuel prices. Fuel prices are reflected as a cost on food products in many items ranging from tractors used in agriculture to lorries providing logistics. It is seen that fuel prices are high in Turkey. There are two different reasons for this. The first reason is exchange rate increases and the second reason is the high rate of special consumption tax on fuel prices. In order to reduce food inflation, it is essential to reduce food production and logistics costs. This study aims to investigate whether fuel prices have an effect on food inflation. In the study, monthly petrol, diesel prices and food price index between 2005 and 2022 are used. In order to take into account the effect of rare events such as the Covid 19 pandemic, Fourier KPSS and Fourier Shin co-integration test were used in the study. According to the findings of the analysis, the existence of structural breaks in the series was determined. In addition, the existence of a long-run relationship between the series was found in the analysis findings. Finally, the findings of the analysis indicate that fuel prices increase food inflation in the long run.
