This paper demonstrates that globalization, taking the form of a higher import component of consumption and a larger export component of GDP, is the cause of the apparent breakdown in the relationship between excess demand and inflation. Within a parsimonious empirical framework, we show that increasing openness of the US economy is all that is needed to re‐establish the relationship between inflation and capacity utilization. We also show that international trade has a significant separate influence on inflation, and is important for identifying a Phillips curve relationship between unemployment and inflation.
