According to Wikipedia, the probably most widely used and most broadly reviewed encyclopaedia on earth, and the references cited therein, economics as a term was suggested by economists in order to establish their science “as a separate discipline outside of political science and other social sciences”. Looking back at my study of economics, I have to say that we probably pursued this intention a bit too far.
The definition for economics as well as economic science to be found in textbooks, dictionaries, and encyclopaedias often reduces our subject to concerns about “production, distribution, and consumption of goods and services”. In addition, we commonly narrow our investigations further down to only those goods and services whose exchanges are market outcomes or are at least accompanied by official transactions. At the end, we frequently draw conclusions about optimality with regard to welfare and utility while a huge part of interactions, which our utility and welfare depend on, is not even taken into account.
It simply may not be a good idea to separate economic science from other social sciences, while final conclusions about the economic system can hardly be drawn independent of the social system it is embedded in. Instead of narrowing our perspective, we should rather reconsider a broader definition of economic science which is still used in some textbooks, according to which we should deal with all of those human activities that serve the satisfaction of needs. This does not only extent our investigation to individual behaviour aside from markets. It also emphasizes that it may be fundamentally wrong to exclude normative considerations from economic analysis. If our welfare and utility also depends on the satisfaction of needs for things like fairness and equality, our concept of efficiency has to be refined.
This already suggests that also the intended separation from political science has to face limits. In addition, every exchange and negotiation, on markets or not, crucially depends on initial endowment and corresponding bargaining power. Endowment as well as power is not god-given. Just like markets are not god-given institutions. They are manmade and just like every law and order they root in temporary compromises. There is no property right that does not depend on normative rules in the past. There is no economic outcome that does not depend on the institutional framework determined by the political system in charge.
For the same reasons, there may be no separation of economics from other social and political sciences without a corresponding loss in validity of our conclusions. While we certainly have to specialize in our disciplines, our disciplines themselves should not specialize more than there interdependencies allow for.
