Speed Matters: Limited Attention and Supply-Chain Information Diffusion
We develop a new measure for the speed of firm-level information diffusion in stock prices and study its determinants and implications. Using local flu epidemics as exogenous attention shocks, we show that inattention from dual-covering analysts and cross-holding institutions decreases the speed of information diffusion from customers to suppliers. Supply-chain information diffusion matters for investors and firms: we document that information diffusion speed drives customer momentum strategies, affects the price feedback effect for corporate investment decisions, and enhances supply-chain coordination. Our findings demonstrate that attention from key information intermediaries affects information efficiency with important implications for real economic outcomes.
