内容简介:

In this study, we examine capital market-related agglomeration spillovers associated with large plant openings (referred to as “million-dollar plants”, MDPs). We consider whether reductions in information processing costs benefit incumbent firms that are geographically proximate to the MDP, resulting in increased analyst coverage and institutional investment. Specifically, we find that a broker (mutual fund) that covers (invests in) the MDP firm is more likely to cover (invest in) an incumbent firm following the MDP event, relative to a broker (mutual fund) that does not cover (invest in) the MDP firm. The effect is stronger in counties with lower ex-ante capital market awareness and among firms that exhibit stronger economic co-movement with the local economy or have a larger local presence. The effect also exists even when the incumbent firm operates in a different industry from the MDP firm. We also find decreases in illiquidity, volatility, and bid-ask spread for incumbent firms in the winning county relative to incumbent firms in the runner-up counties. Overall, we provide evidence of capital market agglomeration spillovers.
