The effects of internal migration on regional wage and unemployment disparities in Canada

"This paper examines the role of the migration mechanism in the context of a general interregional factor flow adjustment model. Using an estimation technique, which pools cross-section and time series data, the direct effects of migration flows and regional investment on the growth of regional wages and unemployment [in Canada] are examined. The results suggest that migration has a small, but significant impact on regional wages and unemployment rates."     

Linked population and economic models: some methodological issues in forecasting,analysis, and policy optimization

Some problems associated with demographic-economic forecasting include finding models appropriate for a declining economy with unemployment, using a multiregional approach in an interregional model, finding a way to show differential consumption while endogenizing unemployment, and avoiding unemployment inconsistencies. The solution to these problems involves the construction of an activity-commodity framework, locating it within a group of forecasting models, and indicating possible ratios towards dynamization of the framework. The authors demonstrate the range of impact multipliers that can be derived from the framework and show how these multipliers relate to Leontief input-output multipliers. It is shown that desired population distribution may be obtained by selecting instruments from the economic sphere to produce, through the constraints vector of an activity-commodity framework, targets selected from demographic activities. The next step in this process, empirical exploitation, was carried out by the authors in the United Kingdom, linking an input-output model with a wide selection of demographic and demographic-economic variables. The generally tenuous control which government has over any variables in systems of this type, especially in market economies, makes application in the policy field of the optimization approach a partly conjectural exercise, although the analytic capacity of the approach can provide clear indications of policy directions.     

制订新教学计划的基本方针和准则

在改善专家培养的这个复杂问题中,教学内容及其与社会经济和科学技术进步的要求相适应,有着头等重要的意义。因此,修订教学计划乃是客观的必然规律。一九七二年到一九七三年制定的教学计划有许多特点:加强了科目的统一,从而保证对学生进行的普通教育、普通技术教育的可能范围内的普通专业教育的系统化;计划更加机动灵活,以便能及时修改专业科目的教育内容;提高了对学生平时学习成绩的检查的作用和意义。这些教学计划曾规定就经济学,生产的组织和计划,技术程序的自动化,劳动保护和劳动法方面大大提高学生的教育水平。此外,计划中还酌量对具体专业班级的特点作
