The Microeconomic Foundations of Aggregate

2019-7-22  Aggregate production functions may fail to exist if there is no single quantity index corresponding to final output; this happens if final demand is non-homothetic either be-cause there is a representative agent with non-homothetic preferences or because there are heterogeneous agents with different preferences. Furthermore, aggregate production

The Microeconomic Foundations of Aggregate

2019-7-22  Aggregate production functions are reduced-form relationships that emerge en-dogenously from input-output interactions between heterogeneous producers and factors in general equilibrium. We provide a general methodology for analyzing such aggregate production functions by deriving their first- and second-order properties.
