We develop a methodology to disentangle sources of capital "misallocation," i.e., dispersion in value-added/capital. It measures the contributions of technological/informational frictions and a rich class of firm-specific factors. An application to Chinese manufacturing firms reveals that adjustment costs and uncertainty, while significant, explain only a modest fraction of the dispersion, which stems largely from other factors: a component correlated with productivity and a fixed effect. Adjustment costs are more salient for large US firms, though other factors still account for the bulk of the dispersion. Technological/markup heterogeneity explains a limited fraction in China, but a potentially large share in the United States.
