INteresting analyse, through I disagree. I have followed the party since its start in 1995, and while it have sometimes argued for what we would see as social democratic economic values, just as often it has argued for liberal or conservative values. Yes DPP has called itself the new Social democratic party, but it has also called itself the new centre party and the new conservative party. It have tradionational been a party which adapt much of its policies to what was popular and used ideologies buzz words as nothing more than someting to beat other parties in the head with ("we are the real social democratic/conservative/centre party not you", some of the MPs has even defined themselves as liberals. The problem is worsen by the fact that their princip program includes no comments about their economic views, and only in their working programs we see mentioning of taxes (they would like to see lower taxes but not without equal cuts, also they support the "tax stop"). Compare them to the Socioal Democrats who goes in much deeper detail about how they want a more equal society, and they are clearly to the right of them.
Yes economic they lay to the left of the Social Liberals (but right now everybody but LA do so too). I would put them economic as a traditional centre right party, where they share economic position with Venstre's left. But hjonestly they are hard to place because economy have never been a important part of DPP's platform.
When they have called themselves the real conservative party it has been in relation to their stances on immigration, law and order, schools etc. They have to a rather large extent adapted the traditional conservative line of "God, King and Fatherland" while at least some parts of the Conservatives have moved towards international, liberal views.
I agree that the DPP's economic policy is more like take things as they come which makes them somewhat hard to place, but I will maintain that their policies are generally rather similar to those of the SD. It's of course always difficult to compare as SD has also changed their attitude to f.ex. taxes several times. Helle Thorning was in favor of the "tax stop" when she was elected leader, then she made the "fair" agreements with SPP that included tax rises, and recently they agreed on a tax reform that lowered taxes and cut the state benefits for unemployed, some pensioners etc.
DPP not only opposed the latest tax reform, they also opposed reforms/cuts on early retirement benefits and flexible jobs. They introduced the "elderly cheque" and generally worked for better conditions for, especially the poorest, pensioners.
