As for the idea that Danish People Party not being right wing, it's a common theory among embarassed right wingers, but they have supported neoliberal policies, tax cuts and removal of labour rights, so yes they are right wing.
To call DPP a right winged economic party only really makes sense if you think that all other parties, except the Red-Green Alliance, are right winged as well. And while that's a legitimate view it does make little room for looking at the differences in economic policies that exist between those parties.
DPP's economic policies are broadly social democratic. They will support more liberal economic policies when they are in power due to the parliamentary situation in much the same way as the SD and SPP now support more liberal economic policies due to the parliamentary situation. The tax reforms are good examples; when the DPP was in power and agreed on fairly liberal tax reforms, the SD and SPP criticised them for being unfair and favouring the rich, and now when the SD and SPP are in power and makes a fairly liberal tax reform, the DPP criticised it for being unfair and favouring the rich.
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.
