The economics of citizenship: a common intellectual ground for social scientists?
Economists studying the economic behaviour of immigrants have tended to avoid serious interdisciplinary work. I argue that when presented with a particular set of research questions that lend themselves to a utility maximisation framework, an economist will be able to pursue interdisciplinary work. I further argue that the necessary if not sufficient ingredient for true economic collaborative research has been met in the field of citizenship acquisition. I review the existing empirical research on citizenship acquisition and its economic impacts to support this argument.
