现代国际贸易理论中的国内和国际规模收益   总被引:1,自引:0,他引:1  
在二战后的国际贸易中,工业化国家之间的制造业产品的交易量巨大,这种产业内贸易现象的出现,在一定程度上对传统的赫克歇尔-俄林-萨缪尔逊贸易模型产生了冲击和质疑。经济学家从多个角度寻求对这种现象的理论解释,并开始注意产品差别化及其对规模经济的影响,但是,这些研究对贸易理论的影响很小,并且解释现实的能力也很弱。因此,把差别化的生产资料作为研究的重点,在国际收益的框架下,建立模型以推出国际规模收益,并且运用这一模型得出了国际规模收益、传统的国内规模收益和要素禀赋论之间的关系。  相似文献

"Using 1980 census and 1987 survey data on birth cohorts to examine recent primary and secondary school enrollment trends [in Thailand], this study reports that primary enrollment is nearly universal but secondary enrollment is much less prevalent. The study assesses several factors thought to influence enrollment and finds that urban residence, parents' completion of primary school, the mother's positive attitude toward education, and the family's being comfortable economically to be associated with children's enrollment in secondary school. It also indicates that, for moderately well-off families, proximity to schools has a major influence on secondary school attendance. For the wealthiest families, however, distance is not a hindrance to attendance, and for the poorest families, having a school nearby is not sufficient to ensure attendance."  相似文献

The Planning and Statistical Department of the State Family Planning Commission of China in July 1988 implemented a fertility and birth control survey in China on 2.16 million married women ages 15-57 using stratified, systematic, clustered, and non-proportionate sampling. 3 questionnaires were used: household, married women, and sample unit covering basic status, family planning status, general characteristics of pregnancy and contraception, population flow, deaths since 1981, and socioeconomic status. The authors suggest several international cooperative research projects including: design of fertility and contraception survey; Chinese population growth; Chinese population dynamics; dynamics of marital and family status; fertility; contraception and birth control; mortality; migration; status of the nationalities of China; population development; regional fertility status; and others. Data from the survey will be available in June 1989.  相似文献

The authors develop an econometric model to examine the impact of migration on fertility in Greece in the period 1968-1986. In the model, the fertility equation is considered within a simultaneous equation system, and international migration is included as an explanatory factor of both fertility and per capita income.

According to long-term follow-up studies of people diagnosed schizophrenic, one half to two thirds will become normal and be back in the community after a period of years. With evidence that schizophrenia is reversible, professions involved in social control and those doing therapy face new responsibilities. Therapists can approach psychotic symptoms expecting the person to become normal. The goal is to help people past periods of acute disturbance without doing them long-term harm.  相似文献

Research on family therapy training has produced very little data regarding the kinds of trainees that do best in family therapy training programs. This study attempts to provide some rough and preliminary data on that issue. One hundred and seventy trainees, drawn from seven different structural!strategic training experiences, were evaluated as to how much they learned by taking the Family Therapy Assessment Exercise pre- and posttraining. Their performance was correlated using a hierarchical regression analysis with a number of trainee variables such as amount of conjugal family experience, amount of experience doing family or individual therapy, or prior knowledge of family therapy. The results indicate that, as predicted, conjugal family experience was positively related, and prior knowledge was negatively related to performance. Prior experience doing individual therapy was also positively related to performance.  相似文献

Working with a treatment and observing team at the same time, behind the oneway mirror, offers a variety of ways to: (a) generate multiple realities; (b) work with two different models of family therapy simultaneously; and (c) provide feedback on the teams' own roles, rules and group process. The process that 6 trainees and two supervisors used with T and O teams to examine their own coevolution as a therapeutic system using the Milan model of family therapy and Ericksonian hypnotherapy is described. The article concludes with a discussion of the advantages and pitfalls of this type of dual supervision.  相似文献

This article reviews conventional theories about different aspects of labor migration: its origins, stability over time, and patterns of migrant settlement. For each of these aspects, the authors provide alternative explanatory hypotheses derived from the notions of increasing articulation of the international system and the social embeddedness of its various subprocesses, including labor flows. A typology of sources and outcomes of contemporary immigration is presented as a heuristic device to organize the diversity of such movements as described in the empirical literature.  相似文献
