Scope conditions of economic voting: The Danish exception?

In country after country, economic voting analysts have found that voters react sociotropically rather than egotropically. However, in a series of papers Nannestad and Paldam have found the exact opposite result for Danish voters - a result which challenges the scope conditions of economic voting. Changing only a few minor aspects of Nannestad and Paldam's design, including the introduction of a standard sociotropic item in their models, though, reproduces the standard result: strong sociotropic and weak egotropic effects. The challenging results thus seem to be methodological artefacts; a finding that strengthens confidence in the generalizability of the basic mechanism of economic voting. Voters are not necessarily altruists, however. Sociotropic voting may be driven by both egoistic and altruistic considerations.
