This paper develops a multisectoral framework for the measurement of persistence of shocks to sectoral and aggregate output, and provides a decomposition of the contribution of shocks from different sources to the overall persistence measure. The framework is applied to U.K. output data,...

A choice criterion is proposed for discriminating between disaggregate and aggregate models estimated by the instrumental variables method. The criterion, based on prediction errors, represents a generalization of criteria developed in the context of classical regressions models. The paper also...

This paper focuses on whether to use macro or micro equations to predict aggregate variables. The Grunfeld-Griliches prediction criterion is generalized to allow for contemporaneous covariances across the micro equations and for parametric restrictions on the disaggregate equations. An...

This paper discusses alternative methods of testing for aggregation bias and proposes direct tests of the discrepancy of the macroparameters from the average of the corresponding microparameters, and derives tests of aggregation bias in the general case where the parameters of interest may...
