Political connections, institutional environment and informativeness of stock price

This study empirically investigates how political connections affect the information content of stock prices. We find that political connections increase stock price synchronicity; political connections in the category of government officials significantly increase stock price synchronicity; political connections in the category of industrial and commercial associations significantly decrease stock price synchronicity; the relationship between political connections in the category of NPC deputies and CPPCC members and stock price synchronicity is not significant; political connections in the category of NPC deputies and CPPCC members significantly increase stock price synchronicity in the case of direct listing.
