The expectations-augmented Phillips Curve (EAPC) can be regarded as an aggregate macroeconomic relationship that contains several distinct mechanisms for inflation determination. Explain and discuss how inflation occurs through such mechanisms and how the conduct of monetary policy affects inflation. Also, using the given dataset from the IMF World Economic Outlook database on the G7 countries and simple techniques in Excel (e.g., plotting a trendline or regression analysis), estimate a simple EAPC for any country of your choice and discuss your results. If you break the estimation period into two sub-periods 1980-2009 (i.e., before GFC) and 2010-2021 (post-GFC), is the estimated EAPC stable?
