We shed light on the complementarity between firms electoral campaign contributions and their lobbying activity through three stylized facts.

Last, we find that f irms lobby on the new issues treated by legislators to whom they have contributed after these legislators are reassigned to new committees. Based on these key facts, we introduce a new definition of political connections based on persistent campaign contributions between firms and legislators.We then exploit the strategic links between lobbying activity and campaign contributions to build a new instrument that accounts for the endogeneity of firms\u2019 lobbying topics and provide new estimates on the impact of lobbying on firm size, financial performance and investments.<\/p>","protected":false},"excerpt":{"rendered":"<p>How do firms build their political influence?
