Intergenerational cooperation within the household: a Public Good game with three generations

We analyze cooperation of individuals in a family context, using a Public Good game. In a lab experiment, 165 individuals from 55 three-generation families (youth, parent, and grandparent) play a repeated Public Good game in three different treatments: one in which three members of the same family play each other (family), a second with the youth and two non-family members, while preserving the previous generational structure (inter-generational), and a third in which three randomly-selected players play each other (random). We find that all the age groups cooperate more when playing with relatives, indicating that family ties may have a positive relationship to contributions to the Public Good. We also find that this trend is more evident for the youths and the parents than for the grandparents. Furthermore, young individuals tend to cooperate less than older generations, especially in non-family treatments. Our results serve as evidence of the relationship between family ties and inter-generational cooperative behaviors.

     

Design of ISD-1: an instrument for social diagnosis in care homes for older persons*

This article describes the design process and main features of an instrument developed for use in the specialist area of intervention in care homes for older persons. The essential aim of ISD-1 (instrument for social diagnosis) is to permit the correct formulation of social diagnoses and to standardise and define the professional language used by social workers. Its content has been organised into 4 dimensions of social diagnosis, divided into 15 sub-dimensions containing 83 diagnostic categories. This work was performed in Spain, in the 24 care homes of the Madrid Social Care Agency of the Community of Madrid, involving the participation of the 40 social workers practising in these centres. ISD-1 is an easily understood and used tool, of potential use for social workers practising in care homes for older persons and capable of being adapted for use in other institutional environments, as well as being capable of adaptation and translation for its application in other countries.     

Why do newcomers vote for a newcomer? Support for an immigrant party

This article studies the voters of DENK, the first immigrant party to gain seats in a national parliament. It builds further on the existing literature on how immigrants and people from immigrant descent vote in Western European countries. From the literature we derive seven expectations about the kind of voters that are likely to vote for an immigrant party in terms of their political cynicism, attitudes towards economic, globalisation and moral issues. We find that DENK voters are younger Muslims, who have conservative views on moral matters, cynical attitudes towards politics, right-wing views on economic matters and progressive views on issues that pertain to the globalisation dimension, such as immigration, integration and Islam and in particular discrimination. This article uses VAA data to construct a matched sample that in terms of key variables is representative for voters with and without a migration background.

公共性和效率性观点下公共产品供给模式多元化及其潜在问题

公共产品供给模式的多元化无论在理论还是实践上都极具争议,其产生之因是,通过多主体的协调配合可以克服政府及市场供给的无效或低效,但多元化机制中各主体的协调配合也会发生失效,一样会造成供给的效率损失以及产品公共性缺失的问题。而避免这种问题,政府必须发挥多元机制中的主导和协调作用,从而实现公共利益的最大化。

对马克思生产价格范畴的解读

在《资本论》第一卷中马克思认为商品是依据价值交换的,而在《资本论》第三卷中马克思又提出资本主义商品是按照生产价格交换的。对此,我国理论界对马克思的"生产价格"概念有不同的理解。从本质层面来看,生产价格与价格相比较,是性质不同的两个概念,生产价格是自由竞争资本主义对期商品价值的发展形式,即商品价值的一种具体表现形式,它不是一般意义上所理解的价格,它存在的历史前提是自由竞争资本主义时期,它在量上等于成本价格与平均利润之和。     

日本韩国城市化中农地保护的经验及启示

城市化发展加快导致农地紧缺已成全球性问题.日本、韩国分别从法律制度、土地规划、土地管理以及生态保护等方面加强本国城市化进程中农地的保护,并取得了瞩目成就.在新型城镇化建设飞速发展的今天,我国应充分借鉴日韩两国的有益经验,构建系统完善的农地保护法律制度体系,建立有效的土地使用规划配套机制,确立与新形势相适应的土地用途管理机制,并加强农地生态保护建设.
