ABSTRACT
This article nowcasts US quarterly real GDP growth rate with dynamic factor model (DFM) using Divisia Monetary Aggregate Index, Divisia M1, M2, M3, and exploits information from a large, unbalanced panel data. GDP nowcasting is evaluating the current quarter GDP given the available economic data up to the point when the nowcasting is conducted. GDP data is published quarterly with a substantial lag, while many monetary and financial decisions are made at a higher frequency. Therefore, nowcasting GDP has become an increasingly important task for central banks. This article uses DFM to nowcast GDP, compares the nowcasting results from DFM with the simple sum monetary aggregate M1, M2, M3, to the Model with weighted corresponding Divisia Index, then calculates the contributions of the Divisia Monetary index to US GDP nowcasting.

12 MAPFE is the average percentage of the absolute forecast error away from the actual official GDP data, it is another standard accuracy indicator of the forecasting results.
13 Moneyness measures the liquidity of monetary assets. Currency and coin are the most liquid (hundred percent liquid) and other monetary assets are not hundred percent liquid.
14 Prices of monetary assets are measured by the user costs or the opportunity costs of holding the asset for its liquidity services rather than investing it to obtain a much higher interest rate (Barnett Citation1980).
