操纵市场行为的几个基本问题

操纵市场行为的定义、法律性质与分类等基本问题是充分监管、有力处罚和有效预防操纵市场行为的基础性问题。操纵市场行为应当定义为以欺诈致使他人从事证券交易为目的,制造虚假的证券交易或者其他虚假现象的行为。操纵市场行为的法律性质不是垄断、恶意投机,而是证券欺诈。操纵市场行为可分为交易型和非交易型两大类,合同型和行动型操纵市场行为不应成为独立的种类。     

转喻视角下英语间接回指的分类研究

回指是一个语言表达式在同一篇章中被用来指代另一个语言表达式所表达的意义或事物的语言现象.回指可以分为直接回指和间接回指.从认知语言学中的概念转喻视角,以间接回指中整体与部分之间的映射以及间接回指中部分与部分之间的映射为依据,间接回指可分为辐射类、预设类、上下义类三大类和邻近类、因果类、前后景类三大类.     

行政诉讼类型界说

行政诉讼类型是依照一定标准对人民法院审理具体行政行为的活动进行归类而形成的诉讼形态。它具有内容的概括性、划分标准的多样性及与诉讼活动联系的密切性三个特征。它与刑事诉讼类型、民事诉讼类型、行政诉讼模式、行政诉讼请求、行政判决有一定的联系与区别，在本质上体现了对行政相对人的权利救济。     

品类个性的形成与作用机理

现有产品分类法没有反映消费者品类需求的差异,不能很好指导行业营销实践,而品类个性的提出为品类特性研究提供了全新的思路。本研究对影响品类个性形成的因素以及品类个性对品牌个性和品牌传播的影响进行逻辑分析,探索性地提出了解释品类个性形成和作用机理的结构模型。研究表明,消费需要类型、产品物理形式和产品生命周期等3个因素影响了品类个性的形成,所得到的品类个性可采用维度的方法描述。品类个性对品牌个性的选择和品牌传播的设计起指导作用。     

时间序列平稳性分类识别研究

平稳性检验是时间序列回归分析的一个关键问题,已有的检验方法在处理海量时间序列数据时显得乏力,检验准确率有待提高。采用分类技术建立平稳性检验的新方法,可以有效地处理海量时间序列数据。首先计算时间序列自相关函数,构建一个充分非必要的判定准则;然后建立序列收敛的量化分析方法,研究收敛参数的最优取值,并提取平稳性特征向量;最后采用k-means聚类建立平稳性分类识别方法。采用一组模拟数据和股票数据进行分析,将ADF检验、PP检验、KPSS检验进行对比,实证结果表明新方法的准确率较高。     

Childhood family structure and young adult behaviors

This paper examines a wide variety of forms, and full histories, of family structure to test existing theories of family influences and identify needs for new theories. The focus is on links between childhood family structure and both completed schooling and risk of a nonmarital birth. Using a 27-year span of panel (PSID) data for U.S. children, we find that: (a) change is stressful, (b) timing during childhood is relevant, (c) adults other than parents are important, and (d) two more recently studied family structures (mother-with-grandparent(s) and mother-with-stepfather) do not fit the molds of existing theories. The findings suggest that new theories should consider allocation of resources and reasons people group into family structures. Received: 11 September 1998/Accepted: 27 March 2000     

Intention to emigrate in transition countries: the case of Albania

We analyse the profile of potential emigrants from Albania using data from the Central and Eastern Europe Eurobarometer in 1992. Respondents were asked to rate on a four-point scale the likelihood that they would go to live in Western Europe. Our results show that intention to emigrate is correlated positively with males, education and certain occupations, and negatively with age. There is little relation between emigration and income. Those who support the introduction of a free market in Albania are also more likely to emigrate than those who do not. Received: 24 August 1998/Accepted: 17 April 2000     

Saving behaviour and earnings uncertainty: Evidence from the British Household Panel Survey

For the first time, this paper uses a panel data set, the British Household Panel Survey, to analyse saving behaviour in Britain. One objective is to test the precautionary saving hypothesis, according to which households save to self-insure against uncertainty. Our results show that in accordance with this hypothesis, various measures of uncertainty based on earnings variability have a statistically significant effect on households' saving decisions. Moreover, in accordance with the life cycle model, households save more if they expect their financial situation to deteriorate. Received: 15 June 1999/Accepted: 4 January 2001     

Ecosystem resilience, specialized adaptation and population decline: A modern Malthusian theory

The purpose of this article is to construct a theoretical framework characterizing the interactions among economic development, ecosystem equilibrium and possible population decline, and to discuss the population dynamics in the very long run. In our framework, economic activities bridge population and environment. On the one hand, human beings reform the environment through economic activities; on the other hand, economic activities decrease environmental resilience and increase the possibility of an environmental change in a discontinuous and irreversible pattern, as described in Arrow et al. (1995). Furthermore, a highly developed economy also causes over-specialization of human adaptation, which tends to exaggerate the impact of an environmental change on human population size.

The cost of children: May the collective approach to household behavior help?

The collective approach to household consumption behavior tries to infer from variables supposed to affect the general bargaining position of household members information on the allocation of consumptions goods and tasks among them. This paper investigates the extension of previous work to the case where children may be considered as a public consumption good by the two adult members of a household. The main question being asked is whether it is possible to retrieve from the aggregate consumption behaviour of the household and the relative earnings of the parents information on the allocation of goods between them and children. This alternative approach to the estimation of the ‘cost of children’ is contrasted with the conventional approach based on a ‘unitary’ representation of and demographic separability assumptions on household consumption behaviour.
