Measuring Aggregate Productivity Growth Using Plant-Level DataWe define aggregate productivity growth as the change in aggregate final demand minus the change in the aggregate cost of primary inputs. We show how to aggregate plant-level data to this measure and how to use plant-level data to decompose our measure into technical efficiency and reallocation components.how to determine aggregate plant,Measuring Aggregate Productivity Growth Using Plant-level DataAbstract.
