Economics can be considered the science that deals with marketplace efficiency, or it can be viewed as a social science, which deals with human policy goals considered generally. The view Amartya Sen (1987) takes of the matter is that the broader view is the more correct. There is one large and important group of human goals that the mainstream professional economists systematically omit from their discipline: collective goals, especially other-regarding collective goals. How investigators can isolate lists of social goals that persons consider important is discussed. Using these it should not be difficult for social scientists to proceed to provide analysis, drawing upon all the relevant theoretical and imperical knowledge, and so making predictions for opportunity costs in terms of all the other goals of moving a unit closer to any goal (particularly a goal of central concern).
