随着我国高校毕业生数量的增加,大学生的就业问题也日益严峻,民工荒问题凸现。本文结合自身工作实践,就当前的就业问题和制度进行初步分析和对策探讨。     

Forecasting the semiconductor industry cycles by bootstrap prediction intervals

In recent years, there has been a recognition that point forecasts of the semiconductor industry sales may often be of limited value. There is substantial interest for a policy maker or an individual investor in knowing the degree of uncertainty that attaches to the point forecast before deciding whether to increase production of semiconductors or purchase a particular share from the semiconductor stock market. In this article, I first obtain the bootstrap prediction intervals of the global semiconductor industry cycles by a vector autoregressive (VAR) model using monthly US data consisting of four macroeconomic and seven industry-level variables with 92 observations. The 24-step-ahead out-of-sample forecasts from various VAR setups are used for comparison. The empirical result shows that the proposed 11-variable VAR model with the appropriate lag length captures the cyclical behaviour of the industry and outperforms other VAR models in terms of both point forecast and prediction interval.     

缩小数字鸿沟对退休再就业是否有帮助

本文使用CHARLS 数据构建了Logit 模型，以数字鸿沟为核心解释变量，结合个人特征、社会保障和对外经济支持等方面分析了数字鸿沟对退休再就业的影响。研究发现，其中老年数字鸿沟能够减少退休后的受雇就业，导致更多的退休人口选择不就业，但是对退休后是否自雇就业没有影响。综合而言，缩小老年数字鸿沟对退休再就业有显著的积极作用。此外，男性退休后更倾向于受雇就业，女性通常更需要照顾家庭。年龄对退休后受雇就业和自主经营具有负向影响，且影响程度相当。健康状况和社交活动参与对退休再就业也有显著影响。基于研究结果，本文提出相应的对策建议。
