The new research provides the following advance relative to the state of art. The first article, “Brain Drain as Exploitation”, provides the first full-length ethical analysis in the literature of the claim that developed states that rely on skilled working-age immigration in order to re-balance the proportion of their younger workers and retired elderly citizens, may be engaged in a form exploitation of the developing states that those skilled immigrants leave behind. This opens up a new, important avenue of research because it suggests that immigration policies of EU member states towards developed states needs to be reconsidered – in particular, the EU needs to examine whether its attempts at recruiting skilled immigrants from developing states amounts to a form of exploitation of those states.
The second article, “The Case for Replacement Migration”, provides the first full-length ethical analysis in the literature of the claim that developed states should give priority to relying on immigration over a policy of increasing fertility (pronatalism) in order to increase the proportion of younger workers in their populations. The research article shows that this prioritisation of “replacement migration” over pronatalism should take place only in those cases in which immigration would not amount to the exploitation of developing states. Policies. While the concept of “replacement migration” has been examined by demographers (since the concept was first introduced by the UN in 2001), my research article is among the first few articles on the topic in the field of ethics and political philosophy.
The third article, “Age, Justice, and Longevity”, advances the state of the art by closely examining an issue that has not been extensively discussed by moral and political philosophers to date, namely, how variation in longevity between different individuals should impact on their contributions to welfare state programmes. As with the two other research articles that this project has produced, this third article examines territory that is almost completely new to ethics and political philosophy. It is hoped that these three research articles, together with the other activities conducted during the project, will stimulate further research that can help to inform a transparent and ongoing public debate on how the EU can best respond to the pressures of population ageing.
