Is politics under increasing corporate sway?: A longitudinal study on the drivers of corporate access

This article analyses patterns in interest group access to the political process in the Netherlands from 1970 to 2017. Research has indicated that corporations are amongst the most frequent participants in contemporary political systems. Yet such research has had a strong focus on the US, leaving a gap in our knowledge of corporate lobbying within Europe. This study demonstrates for the first time in a European context that, in contrast to several decades ago, corporations have managed to increase their access to the political process. In doing so, the article tests a new approach that identifies large-scale interest group populations. The method shows itself to be reliable and can therefore be useful for other scholars. The explanatory model indicates that corporate access increases when the economy weakens and political opportunities increase. Overall, the article demonstrates that business interests have managed to expand their access, contributing to a fragmented interest group system
