Data & Code

Representative-issue specific measures of contributions and lobbying expenditures

These data decompose representative-specific PAC contributions (from the U.S. House of Representatives) across issues and also decompose issue-specific PAC lobbying expenditures across representatives. This is done for i) all PACs, ii) only business PACs and iii) only labor PACs. For a detailed explanation of how these data were created, see Section 3 and the supplementary material of Revisiting the link between PAC contributions and lobbying expenditures.
