Economists are just starting to understand how observed input-output linkages and productivity differences are connected. This column investigates how differences in the distribution of sectoral input-output multipliers interact with sectoral productivities to determine cross-country differences in aggregate income. It finds that the impact of the linkages on productivity are substantial, which in turn has significant implications for policy.
