|May 2013||Exploring Reallocation's Apparent Weak Contribution to Growth|
with Amil Petrin, Sašo Polanec: w19012
Two recent meta-analyses use variants of the Baily, Hulten, and Campbell (1992) (BHC) decompositions to ask whether recent robust growth in Aggregate Labor Productivity (ALP) across twenty-five countries is due to lower barriers to input reallocation. They find weak gains from measured reallocation and strong within-plant productivity gains. We show these findings may be because BHC indices decompose ALP growth using plant-level output-per-labor (OL) as a proxy for the marginal product of labor and changes in OL as a proxy for changes in plant-level productivity. We provide simple examples to show that 1) reallocation growth from labor should track marginal changes in labor weighted by the marginal product of labor, 2) BHC reallocation growth can be positively correlated, negatively correl...
