In this paper we extend the Harris-Todaro model of rural-to-urban migration to include urban agglomeration effects, some urban real wage flexibility, and a government budget constraint. Without employment subsidies laissez-faire migration is excessive unless real wage flexibility and agglomeration effects are high. Laissez-faire migration is too low compared with the first-best outcome supported by a subsidy, if its financing involves no costs. Simulations suggest that such a program would imply a substantial increase in taxation. If, as seems likely, an increase of this magnitude involves economic costs then the optimal outcome falls well short of first-best. 相似文献
The eighteenth-century moral philosopher Archibald Campbell is now largely forgotten, even to specialists in the Scottish Enlightenment. Yet his work is worth recovering both as part of the immediate reception of Bernard Mandeville and Francis Hutcheson's rival moral philosophies, and for better understanding the state of Scottish moral philosophy a decade before David Hume published his Treatise of Human Nature. This paper offers a reading of Campbell as deploying a specifically Epicurean philosophy that resists both the Augustinianism of Mandeville, and the Stoicism of Hutcheson. This leads him onto ground later claimed more conclusively by Hume, whilst helping us to better conceptualise the deployment and recovery of Hellenistic thought in the early modern period. 相似文献
