摘要：This paper formalizes the process of updating the nowcast and forecast on out- put and in°ation as new releases of data become available. The marginal contribu- tion of a particular release for the value of the signal and its precision is evaluated by computing \news" on the basis of an evolving conditioning information set. The marginal contribution is then split into what is due to timeliness of information and what is due to economic content. We ¯nd that the Federal Reserve Bank of Philadelphia surveys have a large marginal impact on the nowcast of both in°ation variables and real variables and this e®ect is larger than that of the Employment Report. When we control for timeliness of the releases, the e®ect of hard data becomes sizeable. Prices and quantities a®ect the precision of the estimates of in°ation while GDP is only a®ected by real variables and interest rates.
