Summary
Bill Barnett has been highly influential in shaping academic research on monetary and financial aggregation, using index number and aggregation theory He is the inventor of the Divisia monetary aggregates and founder of the modern field of aggregation-theoretic monetary aggregation. Bill Barnett has made fundamental contributions to the associated fields of demand-system and flexible-functional-form modeling. In his career, he proved that Theil and Barten’s Rotterdam model could be aggregated over consumers under remarkably weak assumptions, with the addition of a remainder term having properties he explored. In a series of journal articles, he has found Hopf, transcritical, and singularity bifurcation boundaries crossing the parameter estimates’ confidence regions He has found this phenomenon in all classes of dynamical models in widespread use in macroeconometrics.
