We develop a theory linking "misallocation," i.e., dispersion in marginal products of capital (MPK), to macroeconomic risk. Dispersion in MPK depends on (i) heterogeneity in firm-level risk premia and (ii) the price of risk, and thus is countercyclical. We document strong empirical support for...

This paper presents accounting decompositions of changes in aggregate labor and capital productivity. Our simplest decomposition breaks changes in an aggregate productivity ratio into two components: A mean component, which captures common changes to firm factor productivity ratios, and a...
