This review article suggests that there is a new school of comparative lobbying emerging. However, this development is taking place only gradually. Unlike the earlier studies, which studied corporatism/pluralism, outside lobbying and lobbying regulations, the new comparativists are mainly focusing on inside lobbying strategies and success as a function of country-level factors. Yet, the literature still suffers from underdeveloped theories. I stress that our knowledge can be improved with better theorizing. Better theories, in turn, can be formulated by improving the use of quantitative data gathering, qualitative research, formal models and better communication between researchers working with different methodologies in different disciplines.
