Aggregate versus Disaggregate Survey-Based Indicators of Economic Activity∗

چکیده
Qualitative survey data are used widely to provide indicators of economic activity ahead of the publication of official data. Traditional indicators exploit only aggregate survey information, namely the proportions of respondents who report “up” and “down”. This paper considers disaggregate or firm-level survey responses. It derives alternative disaggregate indicators of economic activity relating firms’ categorical responses to official data using ordered discrete-choice models. An application to firm-level survey data from the Confederation of British Industry shows that the disaggregate indicators of manufacturing output growth provide more accurate early estimates of manufacturing output growth than traditional aggregate indicators.

متن کاملChanges in the effects of monetary policy on disaggregate price dynamics
Based on a time-varying factor-augmented vector autoregression, we demonstrate that the propagation mechanism of monetary policy disturbances differs across disaggregate components of personal consumption expenditures. While many disaggregate prices rise temporarily in response to a monetary tightening in the early part of the sample, there is no evidence of a price puzzle at the aggregate leve...
