The Link Between Money and Nominal Spending

The recent financial crisis has reignited interest in the role of money and credit in driving economic activity.

The article shows that when trying to apply this theory to historical data, a complicated interaction between money and nominal spending emerges. And a deeper understanding of the forces driving money demand and supply is required to interpret the information contained in money about the level of activity and inflation.
