Where should Chinese internal migrant parents locate their school-aged children: migrate with them or leave them behind? And should they invest in private education of their children? We investigate whether migrant parents can afford to take their children to migrate and thus provide theoretical optimum that maximizes migrant parents’ utility which includes the children’s educational performance. Depending on the educational investment parents make and the relocation cost of children, we provide necessary and sufficient conditions under which migrant parents should take their children to migrate and conditions under which migrant parents should provide their children with private education.

Where should Chinese internal migrant parents locate their school-aged children: migrate with them or leave them behind? And should they invest in private education of their children? Empirical evidence based on the 2009 wave of the Rural-Urban Migration Survey in China (RUMiC) data is inconclusive. We use an overlapping generations model to find a theoretical optimum that maximizes parents’ utility which includes the children’s educational performance. Depending on the educational investment parents make and the relocation cost of children, we provide necessary and sufficient conditions for migrant parents to take their children to migrate and whether they should provide their children with private education. As the choices of migrant parents affect not only their children’s human capital accumulation, but also on the economic potential of their descendants, we present both short- and long-term consequences of the parents decision.

Tens of millions of young children were left behind by their migrant parents who left to find a job elsewhere to gain a better income and improve their families' living standards. Many studies suggest that migrant parents should bring their children rather than leave them behind, especially EU internal migrants. In this short note, we give an economic reasoning for the choice of migrant parents. Our finding shows that emotionally, bringing the children makes both children and parents better off; however, economically, that may not be the case. The ambiguity depends on the forgone opportunity cost, relocation cost of children, children's motivation, and the quality of the public school at the origin and destination. [less ▲]

Mobile location-based services (LBSs) empowered by mobile crowdsourcing provide users with context- aware intelligent services based on user locations. As smartphones are capable of collecting and disseminating massive user location-embedded sensing information, privacy preservation for mobile users has become a crucial issue. This paper proposes a metric called privacy exposure to quantify the notion of privacy, which is subjective and qualitative in nature, in order to support mobile LBSs to evaluate the effectiveness of privacy-preserving solutions. This metric incorporates activity coverage and activity uniformity to address two primary privacy threats, namely activity hotspot disclosure and activity transition disclosure. In addition, we propose an algorithm to minimize privacy exposure for mobile LBSs. We evaluate the proposed metric and the privacy-preserving sensing algorithm via extensive simulations. Moreover, we have also implemented the algorithm in an Android-based mobile system and conducted real-world experiments. Both our simulations and experimental results demonstrate that (1) the proposed metric can properly quantify the privacy exposure level of human activities in the spatial domain and (2) the proposed algorithm can effectively cloak users' activity hotspots and transitions at both high and low user-mobility levels.
