The aim of this paper is to survey the historiography of Swiss Business Interest Associations (BIAs). Our objective is to contribute to the recent renewal in the research on BIAs, which, in spite of the considerable political as well as economic influence of the latter, has been somewhat neglected. To that end, we first discuss the main traits of Swiss BIAs’ genesis, development and particularities. We then present the quantitative as well as qualitative results of our historiographical survey. We show that researchers have essentially documented the political role of BIAs, but neglected their social and economic importance. We conclude by sketching some of the issues that would be worth addressing in further studies, in Switzerland as well as in other countries.
