Description:
Based on the 10-K listings of public firms, we identify economic connections among U.S. states, which lead to excess comovement in returns and liquidity of firms headquartered in connected states. The economic connections create spillover effects whereby the economy of a state affects its connected states thus amplifying the impact of local economic conditions on the U.S. economy.
