I have already mentioned that it is rather deceptive to discuss economic issues as if they were completely independent from normative judges. Several instruments and analyses regularly applied by economists strongly resort to assumptions and thereby beliefs and opinions. Several outcomes and issues discussed in economics strongly depend on the underlying set of institutions and thereby on the politicians responsible for them.
This is not a critique. My critique is rather reserved for those guys who try to exploit the relinquished political conscience of an economist in favour of an accusation – restate it and belie it as it would be something bad. Some probably do it intentionally and fully aware of their formal mistake. They accuse us of a normative bias because they know that others, less educated with regard to this issue, will follow their lead: tabooing political statements as if they would jar with the objectivity of science. The true intention, though, may be rather contrary directed. Instead of protecting science from political dependency the ulterior motive may be to protect certain political conditions from scientific discussion. The best to keep people from questioning a given set of institutions seems to be preventing critical thoughts about it in the first place.
If I, for example, once again dare to question the actual distribution of wealth and property rights, there is a high chance for an accusation that my request is politically motivated. The accusation may be right or wrong. Anyway, it bears no surplus for the scientific discussion. If economic outcomes depend on property rights, and property rights are determined by politically passed laws, any discussion of economic outcomes is logically linked to politics. Supressing the discussion thereby is not less politically motivated than forcing it. If there is a political dimension anyway, keeping quiet about it may serve an individual strategy but not consistency or even objectivity.
Do not get me wrong! I do not request that every discussion of an economic outcome should turn into a political discussion. All I want to state is that especially progressive economists will not be able to spare it all the time. The moment they request a change in economic settings or behaviour, there is a high chance that they implicitly demand political action. This does not imply political dependency for the one who states the request. It is the economic sphere that depends on the political sphere, not necessarily the economist who realizes and communicates this fact.
To this effect, do not evaluate our work over our explicit or implicit political requests only. Rather control for the assumptions we state in our models and analysis. Verify which interdependencies are incorporated and which are neglected. Check whether you can share our beliefs and follow our derivations. But do not render a technical or professional judgement based on our political conscience. If you want to judge economists with regard to political conscience, start with those who do not have one or try to hide it, because they seemingly did not get what economics is about.
