Aggregation may be harmful but cannot always be avoided in the analysis of complex econometric models. It should be carried out intelligently by choosing ein aggregative model optimally for modes of aggregation speeified in advance, i.e. minimizing the bias introduced by aggregation and...

A widely used method in the analysis of complex econometric models is to replace the "true model" by an aggregative one in which the variables are grouped and replaced by sums or weighted averages of the variables in each group. The analysis of the problem of choosing an aggregative model...

A widely used method in the analysis of complex econometric models is to replace the "true model" by a highly simplified aggregative one in which the variables are grouped and replaced by sums or weighted averages of the variables in each group. The analysis of the problem of choosing an...

This volume collects three independent contributions which discuss the role of computable general equilibrium (CGE) modelling in both research and teaching. The first paper by John Chipman suggests that statistical methods could be incorporated into CGE analysis. He argues that this would allow...
