|May 2013||Exploring Reallocation's Apparent Weak Contribution to Growth|
with Mitsukuni Nishida, Amil Petrin: 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...

|June 2012||Dynamic Olley-Pakes Productivity Decomposition with Entry and Exit|
with Marc J. Melitz: w18182
In this paper, we propose an extension of the productivity decomposition method developed by Olley & Pakes (1996). This extension provides an accounting for the contributions of both firm entry and exit to aggregate productivity changes. It breaks down the contribution of surviving firms into a component accounting for changes in the firm-level distribution of productivity and another accounting for market share reallocations among those firms - following the same methodology as the one proposed by Olley & Pakes (1996). We argue that the other decompositions that break-down aggregate productivity changes into these same four components introduce some biases in the measurement of the contributions of entry and exit.
We apply our proposed decomposition to the large measured increases of pro...
