In the literature, there is evidence of an inverse relation between trade openness and inflation which has been widely questioned. More recently, economic openness has been related to aggregate demand and supply to shed light on inverse openness-inflation in the developed countries. This paper contributes to the literature by examining the long run connection between trade openness and inflation in a developing country, Pakistan, using the Autoregressive Distributed Lag. The empirical finding suggests that the negative openness-inflation relationship holds for Pakistan.
