Contribution payments and information are two important channels of lobbying influence. In his paper, Andreas Polk analyzes what is known about these channels in Germany from a political economy perspective. Based on a discussion of the empirical literature and the available data, he argues that the state of empirical knowledge about lobbying in Germany is rather limited. To improve the understanding of the lobbying process, he identifies research gaps and discusses potential methodological approaches which can be suitable to address these questions. Also, he discusses the role of party donations and temporary employment of bureaucratic staff, based on two novel data sets. The analysis indicates that party donations might play a role as a means to achieve access; in contrast, the temporary exchange of employees in the public administration seems to be of rather less importance in informational lobbying.
