Family migration policy, once basing citizens and resident foreigners' possibilities to bring in foreign family members mainly on the right to family life, is increasingly a tool states use to limit immigration and to push newcomers to integrate into civic and economic life. The family migration policies of Denmark, Norway and Sweden range widely - from more minimal support and age requirements...

BACKGROUND Ubiquitous computing technology, sensor networks, wireless communication and the latest developments of the Internet have enabled the rise of a new concept-pervasive health-which takes place in an open, unsecure, and highly dynamic environment (ie, in the information space). To be successful, pervasive health requires implementable principles for privacy and trustworthiness. OBJECT...

The fact that derivative securities are equivalent to specific dynamic trading strategies in complete markets suggests the possibility of constructing buy-and-hold portfolios of options that mimic certain dynamic investment policies, e.g. asset-allocation rules. We explore this possibility by solving the following problem: given an optimal dynamic investment policy, find a set of options at the...

An ethical rule is supposed to accurately reflect the ethical fact (the fact that the action the rule prescribes is ethically obligatory), whereas rules o...

This paper discusses unilateral sustainability policies for tradable resources in closed and open economies. The effects of sustainability policies are modelled in an intertemporal, competitive framework by applying different sustainability rules which are introduced unilaterally in the domestic country. The paper shows that no sustainability rule will lead to a slower rate of extraction of the...

If asset trade in the initial period takes place before the announcement of policy, a national policymaker can choose a policy rule which reduces the work effort of house...

Interest rate-based rules offer the advantage that they involve little change from the Fed’s current policy-s...
