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...

We explain a puzzle from two recent meta-analyses that cover 25 countries and claim to show that inputs systematically move from higher-value to lower-value activities despite strong aggregate labor productivity growth (ALP). These papers use variants of the Baily, Hulten and Campbell (1992)...

We claim that the standard methodology to study the effects of the reallocation of factors on growth is not adequate in the presence of biased innovations. Labor-saving innovations increase output per worker and may decrease the marginal productivity of labor. Therefore, a reallocation of labor...
