Whereas many writers and scholars interested in the field of social democracy have focused on factors such as the role of economic globalization and electoral pressures, Ashley Lavelle explores the importance of the collapse of the post-war economic boom and lower growth rates since then. He examines how these pressures have led social democrats to embrace neo-liberal policies and become threatened by minor parties and independent politicians. Providing an original argument about the decline of social democracy, the author investigates how its decline has increased the popularity of minor parties and independents, along with the reasons for social democratic membership and electoral decline. This is an important book for scholars of social democracy and the broader themes of world politics, political parties, social movements and globalization.
