"Forecasting Economic Aggregates by Disaggregates." Working Paper No.
This paper considers whether the predictive advantage of disaggregate models remains when forecasting subnational data.
For example, Hendry and Hubrich (2006) use disaggregate models to form forecasts for aggregate variables.
Three econometric models are used: the Chow and Lin (1971) model that disaggregates
the level of GDP; and the Fernandez (1981) and Litterman (1983) models that disaggregate

The Department, on the other hand, disaggregates the cluster into its constituent parts.

Among them are that (1) the cost of responding to these attacks is unpredictable and the existence of known application costs facilitates mergers; (2) the banking agencies will appear less arbitrary in always using the cluster; and (3) consideration of the costs and benefits of the alternatives favor rejecting these protests: the costs on the applicant and on the banking agency to respond to the protest outweigh any benefit to the public because the Department disaggregates the cluster and the chances that a banking agency will require greater divestitures than the Department, while not zero, are certainly small.
