Putting the Politics Into Corporate Political Activity: A Variance Decomposition Analysis of Firm–Government Interactions Across Political Contexts

Despite the wealth of theorizing about the relationship between business and government, research on corporate political activity (CPA) has yet to comprehensively consider how political context (e.g., party ideology and the degree of united or divided party government control) may shift the salience of how CPA materializes across industry-, firm-, and executive-level factors, which can shed light on the level of effects that appear to matter more (or less). To advance our understanding, we conducted a variance decomposition analysis on U.S. public firms (2001–2019), exploring the relative effect of each level on firm (lobbying expenditures and campaign contributions) and government actions (government contracts), and parsing our sample based on whether key government branches are Democrat- or Republican-controlled. We generally found that firm effects explain the most variance, followed by industry, while executive effects explain the least. However, this pattern shifts notably when considering political context across our sample period. As such, our findings have important implications for future CPA research and theorizing.
