"This paper analyses the distribution of a country's population among regions when migration involves fiscal externalities. The main question addressed is whether a decentralized decision making [by] regional governments can produce an optimal population distribution...or a centralized intervention is indispensable, as argued before in the literature.... It turns out that, while with costless mobility the fiscal externality is fully internalized by voluntary interregional transfers, with costly mobility, centrally coordinated transfers still remain indispensable for achieving the socially optimal allocation."

The childhood wish for parenthood when it remains unfulfilled in adult life causes pain to a couple and imposes a strain on their relationship. For a woman's failure to conceive may be rooted in an early unsatisfactory relationship to her mother. The new fertility techniques restore hope to these patients but may not be successful for such women and may also bring new emotional problems in their wake. Spontaneity in sexual relations is constrained, and transference to the doctors who administer techniques, giving or refusing permission for normal sexual intercourse, repeats infantile submission to the powerful parents of the past. Two clinical illustrations are given.
This paper examines some of the unconscious reasons that may lead to unfulfilled pregnancy, either by means of spontaneous abortion, or by conscious planned abortion. During pregnancy the universal dilemma of maternal ambivalence towards the foetus and whom it represents may be strongly influenced by unresolved conflicts and anxieties belonging to earlier stages of a woman's psychic development. Spontaneous or planned abortion, which allows the woman who has become pregnant to deny life to the foetus, may provide a psychosomatic solution to this psychic conflict.
