The title of this thesis is ?The preconditions of the acquisition guarantee- hard to design working political reforms?. The acquisition guarantee (förvärvsgaranti) is a form of credit guarantee issued by the Swedish government to credit institutes that give out housing loans to debtors with poor credit history. The reform hasn´t been used in any substantial extent.The purpose of the study is to investigate whether you could identify any problems with the preconditions that the governmental agency BKN was given to implement the acquisition guarantee, and if so describe which these problems are.Two questions are answered:1.      What preconditions for a working implementation of the guarantee, in the form of rules, objectives and directives was offered by the government in their steering of BKN?2.      How did the structural preconditions for a working implementation of the guarantee look like?By doing a text analysis of central documents I find that the lack of outcome could to some extent be related to weaknesses in how the reform was formulated.
