The Pariah Party Influence on Local Government Formation in Swedish Municipalities 2002-2018 This paper studies the correlation between the rise of the radical right party The Sweden Democrats and the rise of minority governments and bloc transcending/cross-partisan coalitions in Swedish local governments; the role of the Sweden Democrats in this development is studied and further its impact in the relation between right/left-wing governments. Taking off in classical coalition- and government formation theory together with the concept of pariah parties, I also continue to discuss the setting of local government in Sweden and its implication on local government studies in general. Regression analysis of formed government in the 290 Swedish municipalities over the last five local elections, 2002-2018, is used to answer the question of how the pariah party that is the Sweden Democrats, have affected the types of local government in Sweden. The study finds that the rise of the Sweden Democrats in Swedish municipal parliaments to a large extent can explain both an increase of cross-partisan coalitions and of minority governments. This can however only be said when the party holds the balance of power; just the size or sheer presence of the party in local parliaments does not seem to have a significant impact on government type. When the party does hold the power of balance, one can observe a significant shift in favour of right-wing governments over left-wing governments. Albeit not participating in government and being considered a pariah party, or perhaps because of this fact, the rise of the Sweden Democrats has significantly affected the character of Swedish local governments.
