In this article we generalize the aggregation theory in efficiency and productivity analysis by deriving solutions to … the problem of aggregation of individual scale efficiency measures, primal and dual, into aggregate primal and dual scale … efficiency measures of a group (e.g., industry).

This paper discusses conditions for aggregation of heterogeneous expectations in a new-keynesian economy. I show that … aggregation result depends on the way agents form cross-expectations, i.e. expectations on other agents’ decision variables, and I … determine a maximal class of cross-expectations operatorsthat support aggregation. Interpretation of obtained conditions in …
