What's all the fuss about real GDI?

Most analysts agree that real Gross Domestic Income (GDI) is another useful indication of economic activity. For the purposes of monetary policy, however, what ultimately matters, more than any other single measure of economic activity, is real Gross Domestic Product (GDP). This is why real GDP is front and centre in our economic analysis of the economy, particularly in our understanding of the inflation outlook and what direction monetary policy will steer.
