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.
