A theory of permissible illegal immigration

In many countries laws are not enforced against visibly present illegal immigrants. The visibly present illegal immigrants also tend to be concentrated in particular sectors. We explain such permissible illegal immigration in an endogenous-policy model where selective sector-specific illegality transforms illegal immigrants from non-sectorally specialized to sector-specific factors of production. Under initial conditions where no immigrants are present, the median voter opposes immigration. When, however, a population of illegal immigrants has accumulated, ongoing illegal immigration becomes an endogenous equilibrium policy, at the same time that a majority of voters opposes legal immigration and opposes amnesty that would legalize the immigrants' presence. We also establish a basis for domestic voters preferring that illegal immigrants be employed in service rather than traded-goods sectors.     

人口分布、隔离指数及其地理视角——以上海市外来人口分布为例

人口分布具有强烈的地理性,但是相应的空间变动却常常被主流学派所忽视。将空间性思维加入到人口分布的研究当中,关注于不同群体人口分布的局部空间变动,并使用相应的空间性指标进行分析。对这些空间性指标进行了理论探讨,并将其应用于上海市外来人口分布的实证研究中。上海市外来人口主要聚集在距离中心城区10-20公里范围内的近郊区,呈现出有规律性的环状分布。使用空间性的分析指标能够探测出城市社会空间分布的结构,并分析其动力演化机制,为构建和谐的城市社会提供研究依据。     

The Bioeconomics of the Spatial Distribution of an Endangered Species: The Case of the Swedish Wolf Population

Conservation of endangered species often entails significant costs, and, from a social perspective, many species can be characterized as both environmental bads and goods. This paper concerns the management of one such species, the Swedish wolf (Canis lupus). The fact that the wolf tends to disperse over a wide area causes specific management problems. The goal is to choose a harvesting strategy, such that the discounted stream of net benefits from the wolf populations in different geographical regions is maximized. The spatial dimension is involved through emigration and immigration. The solution to the management problem is shown to be a modification of the classical rule of renewable resource exploitation, caused by the migration of wolves between regions. Empirically, this problem is solved by dividing Sweden into 13 geographical regions, and accounting for the existence values, harvesting benefits, and predation costs of the wolf population in each region. The results show that the geographical distribution of wolves, in absolute numbers, is very sensitive to the abundance of prey and to different assumptions regarding the economic parameters of the model. However, the relative distribution of wolves across the country is less sensitive to these assumptions. The highest densities of wolves were found in regions with low marginal costs, due to the abundance of prey in relation to the comparatively low number of human hunters utilizing the same prey as the wolves. The lowest population densities were found in regions with a low carrying capacity for the wolf or with high costs of depredation on reindeer.

我国农民工进城务工收入的调查分析:2000-2008

农村劳动力转移是我国实现工业化必须面对的重大课题,也是解决我国三农问题的根本途径.现阶段我国农村劳动力转移突出地表现为农民工进城问题.农民工进城务工收入的高低,直接影响着我国农村劳动力转移的数量和质量.本文应用第一手调查资料,从农户行为的微观角度研究了我国农民工进城务工收入的变化趋势和影响因素.分析显示:从2000年到2008年,我国农民工进城务工的收入有了较大提高;年龄、性别、学历、收入水平、区位等因素的差异对农民工进城务工的收入有一定的影响.     

广西库区移民土地淹没长期补偿政策研究

1986年以来,我国水库移民安置普遍实行“前期补偿、后期扶持”的政策,随着社会经济的发展,其弊端日益凸现,需要研究出新的更适应实际情况的方法和政策。近年来,广西在水库移民安置方面,坚持从实际出发,总结经验,开动脑筋,集思广益,创造性地实施淹没土地的长期补偿政策,走出了水库移民安置经济补偿的新路子。     

“关系”的魅力与移民的“社会适应”：中哈移民的一个考察

从"关系"、"制度"、"区域选择"三个中心概念入手,通过对移民哈萨克斯坦共和国中国侨民的调查,论证了移民的"异国适应"主要取决于迁入国的移民制度和迁移者的"关系"强弱亲疏.种族歧视性导致了移民在初始状态的不平等,影响了其适应的进度.但对于迁移者个人的心理感受而言,种族群聚地是其最理性的区域选择.
